[0047] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] Reference below Figure 1-Figure 3 A device 100 for measuring the oil consumption of an engine 30 and a method for controlling the device 100 according to an embodiment of the present invention will be described.

[0049] like Figure 1-Figure 2 As shown, the measuring device 100 for the oil consumption of the engine 30 according to an embodiment of the present invention includes: a weighing device 10; a filling device 20, the filling device 20 is placed on the weighing device 10, and the filling device 20 includes a filling tank 21, a controller 22, an oil filling pump 23, a bypass line 24 and an oil pipeline 25. The fuel filling tank 21 is provided with a liquid level detection component 211, which is used to detect the oil height in the fuel filling tank 21. The controller 22 is fixed to the fuel filling tank 21. The pump inlet of the fuel filling pump 23 is connected to the fuel filling tank 21, and the pump outlet of the fuel filling pump 23 is connected to one end of the oil delivery pipe 25. The other end of the oil delivery pipe 25 is used to communicate with the oil pan of the engine 30. The fuel filling pump 23 is used to pump the engine oil in the fuel filling tank 21 into the engine 30. The bypass line 24 connects the fuel filling tank 21 and the oil delivery pipe 25, and the bypass line 24 is provided with a first opening and closing valve 241. The controller 22 is communicatively connected to the fuel filling pump 23, the first opening and closing valve 241, the liquid level detection component 211, and the weighing device 10. The controller 22 is configured to control the fuel filling pump 23 to stop working according to the detection information of the liquid level detection component 211. The controller 22 is also configured to control the weighing device 10 to work. The temperature detection element is provided in the oil pipeline 25 to detect the temperature of the oil in the oil pipeline 25. The temperature detection element is in communication with the controller 22. The controller 22 is also configured to control the first opening and closing valve 241 to open according to the detection information of the temperature detection element.

[0050] The filling device 20 is placed on the weighing device 10, and the weighing device 10 can be used to weigh the filling device 20. The filling device 20 includes a filling tank 21, a controller 22, an oil filling pump 23, a bypass line 24, and an oil delivery pipe 25. The filling tank 21 is used to store the oil to be filled and provide oil to the engine 30. The filling tank 21 is equipped with a liquid level detector 211, which is used to detect the oil level in the filling tank 21. This can prevent the filling pump 23 from priming when the oil in the filling tank 21 is exhausted, thereby reducing the risk of damage to the filling pump 23.

[0051] The controller 22 is fixed to the fuel tank 21. For example, the controller 22 and the fuel tank 21 may be fixedly connected by bolts, or they may be fixedly connected by snap-fitting. However, the present invention is not limited thereto. The controller 22 and the fuel tank 21 may also be fixedly connected by other means, as long as the controller 22 is fixed to the fuel tank 21. The pump inlet of the fuel pump 23 is connected to the fuel tank 21, and the pump outlet of the fuel pump 23 is connected to one end of the oil delivery pipe 25. The other end of the oil delivery pipe 25 is used to connect to the oil pan of the engine 30, thereby achieving communication between the fuel tank 21 and the engine 30, and further enabling the fuel pump 23 to pump the oil in the fuel tank 21 into the engine 30.

[0052] The bypass line 24 connects the fuel tank 21 and the oil delivery pipe 25. A first on-off valve 241 is provided on the bypass line 24. By opening and closing the first on-off valve 241, the bypass line 24 can be opened and closed. Specifically, when the first on-off valve 241 is open, the bypass line 24 connects the fuel tank 21 and the oil delivery pipe 25. When the first on-off valve 241 is closed, the bypass line 24 blocks the connection between the fuel tank 21 and the oil delivery pipe 25.

[0053] The controller 22 is communicatively connected to the oil injection pump 23, the first opening and closing valve 241, the liquid level detection component 211, and the weighing device 10. For example, the controller 22 can be communicatively connected to the oil injection pump 23, the first opening and closing valve 241, the liquid level detection component 211, and the weighing device 10 through a wiring harness, or the controller 22 can be communicatively connected to the oil injection pump 23, the first opening and closing valve 241, the liquid level detection component 211, and the weighing device 10 through wireless communication. As long as the controller 22 is communicatively connected to the oil injection pump 23, the first opening and closing valve 241, the liquid level detection component 211, and the weighing device 10, it will be sufficient.

[0054] The liquid level detector 211 may be an electronic liquid level gauge, and the controller 22 is configured to control the oil filling pump 23 to stop operating based on the detection information of the liquid level detector 211. Specifically, the liquid level detector 211 is used to detect the oil level in the oil filling tank 21. When the liquid level detector 211 detects that the oil level in the oil filling tank 21 has reached a preset level, the liquid level detector 211 feeds the detection information back to the controller 22. The controller 22 then controls the oil filling pump 23 to stop operating based on the detection information of the liquid level detector 211.

[0055] The temperature detection element can be a temperature sensor, which is arranged in the oil pipe 25 to detect the oil temperature in the oil pipe 25. The temperature detection element and the controller 22 are communicatively connected. For example, the temperature detection element and the controller 22 can be communicatively connected through a wiring harness, or the temperature detection element and the controller 22 can be wirelessly connected. As long as the temperature detection element and the controller 22 are communicatively connected, it will be sufficient.

[0056] The controller 22 is further configured to control the opening of the first on-off valve 241 based on the detection information from the temperature detector. Specifically, when the temperature detector detects that the oil temperature in the oil delivery pipe 25 has reached a preset temperature value, the temperature detector feeds the detection information back to the controller 22. The controller 22 then controls the opening of the first on-off valve 241 based on the detection information from the temperature detector, thereby connecting the bypass line 24 to the oil filling tank 21 and the oil delivery pipe 25, thereby allowing the oil in the engine 30 to flow back into the oil filling tank 21. After the oil in the engine 30 flows back into the oil filling tank 21, the controller 22 is further configured to control the operation of the weighing device 10, thereby weighing the filling device 20. By comparing the weight change before and after the oil filling of the engine 30, the engine oil consumption can be accurately calculated. There is no risk of oil splashing during the oil filling, draining, and weighing processes, reducing measurement errors and effectively improving the accuracy of the engine oil consumption measurement results. Furthermore, by connecting different models of engines 30 to the filling device 20, the oil consumption of different models of engines 30 can be measured, thereby greatly improving the versatility of the measuring device 100. Furthermore, the measuring device has a simple structure and is easy to operate. The measurement process can be completed by operating the controller 22, reducing the possibility of manual operation errors and effectively improving measurement efficiency and accuracy.

[0057] Specifically, the measurement process of the measuring device 100 is as follows:

[0058] Before measurement, the fuel tank 21 is connected to the engine 30, and then the oil of the corresponding type and capacity of the engine 30 is added to the fuel tank 21 through the fuel filling port 212 of the fuel tank 21. Before measurement, the first opening and closing valve 241 is in a normally closed state.

[0059] The first time oil is injected into the engine 30: the controller 22 controls the oil injection pump 23 to start, and the oil injection pump 23 starts to pump the oil in the filling tank 21 into the engine 30. At this time, the first on-off valve 241 is in a closed state to prevent the oil from flowing back into the filling tank 21 from the bypass line 24. When the liquid level detection component 211 detects that the oil height in the filling tank 21 reaches the preset liquid level, the liquid level detection component 211 feeds back the detection information to the controller 22. The controller 22 controls the oil injection pump 23 to stop working according to the detection information of the liquid level detection component 211. At this time, the first time oil is injected into the engine 30 is completed.

[0060] The first oil discharge of the engine 30: the engine 30 is controlled to complete the warm-up and then shut down. When the temperature detection component detects that the oil temperature in the oil pipe 25 reaches the preset temperature value, the temperature detection component feeds back the detection information to the controller 22. The controller 22 controls the first on-off valve 241 to open for a first preset time to allow the oil in the engine 30 to flow into the filling tank 21. At the end of the first preset time, the controller 22 controls the first on-off valve 241 to close to stop the oil discharge of the engine 30, and the controller 22 controls the weighing device 10 to weigh and record the first weighing value G1 of the weighing device 10.

[0061] The second oil filling into the engine 30: the controller 22 controls the oil filling pump 23 to start, and the oil filling pump 23 starts to pump the engine oil in the filling tank 21 into the engine 30. At this time, the first on-off valve 241 is in a closed state to prevent the engine oil from flowing back into the filling tank 21 from the bypass line 24. When the liquid level detection component 211 detects that the oil height in the filling tank 21 reaches the preset liquid level, the liquid level detection component 211 feeds back the detection information to the controller 22. The controller 22 controls the oil filling pump 23 to stop working according to the detection information of the liquid level detection component 211. At this time, the second oil filling into the engine 30 is completed. The controller 22 also controls the weighing device 10 to weigh and record the second weighing value G2 of the weighing device 10.

[0062] The engine 30 drains the oil after working for the second preset time: After the engine 30 works for the second preset time and consumes part of the oil, the engine 30 stops working. When the temperature detection component detects that the oil temperature in the oil pipe 25 reaches the preset temperature value, the temperature detection component feeds back the detection information to the controller 22. The controller 22 controls the first on-off valve 241 to open for the first preset time to allow the oil in the engine 30 to flow into the filling tank 21. When the first preset time ends, the controller 22 controls the first on-off valve 241 to close to stop draining the oil from the engine 30, and the controller 22 controls the weighing device 10 to weigh and record the third weighing value G3 of the weighing device 10.

[0063] Among them, G1-G2 is the volume of oil injected before the engine 30 starts working, G3-G2 is the volume of oil remaining in the engine 30 after the engine 30 has worked for the second preset time, G=(G1-G2)-(G3-G2), and G is the oil consumption of the engine 30.

[0064] Thus, by measuring the oil consumption of the engine 30 using the measuring device 100 of the present application, the oil consumption of the engine 30 can be accurately calculated. There is no risk of oil splashing during the measurement process, which reduces measurement errors and effectively improves the accuracy of the oil consumption measurement results of the engine 30. Furthermore, by connecting different models of engines 30 to the filling device 20, the oil consumption of engines 30 of different models can be measured, thereby greatly improving the versatility of the measuring device 100. Furthermore, the measuring device 100 has a simple structure and is easy to operate. The measurement process can be completed by operating the controller 22, which effectively improves measurement efficiency.

[0065] According to an embodiment of the present invention, the device 100 for measuring the oil consumption of an engine 30 connects a weighing device 10, a filling device 20, and an engine 30. Oil is injected into the filling device 20. An oil filling pump 23 is used to pump oil from a filling tank 21 into the engine 30. A bypass line 24 connects the filling tank 21 and an oil delivery pipe 25, allowing the oil in the engine 30 to flow back into the filling tank 21. The weighing device 10 weighs the oil in the filling tank 21. By comparing the weight change before and after filling the engine 30 with oil, the engine oil consumption can be accurately calculated. The risk of oil splashing during the measurement process is eliminated, measurement errors are reduced, and the accuracy of the engine 30 oil consumption measurement results can be effectively improved. Furthermore, by connecting different models of engines 30 to the filling device 20, the oil consumption of engines 30 of different models can be measured, thereby greatly enhancing the versatility of the measuring device 100. In addition, the measuring device has a simple structure and is easy to operate. The measuring process can be completed by operating the controller 22, thereby effectively improving the measuring efficiency.

[0066] According to some embodiments of the present invention, Figure 1 As shown, the other end of the oil delivery pipe 25 has a connecting joint 251 , which is used to communicate with the oil pan, and the temperature detecting element is provided at the connecting joint 251 .

[0067] Among them, the other end of the oil pipe 25 has a connecting joint 251, which is used to connect with the oil pan so that the engine oil can flow into the engine 30 through the oil pipe 25 and the connecting joint 251. The temperature detection component is provided on the connecting joint 251 so that the temperature detection component can detect the oil temperature in the oil pipe 25.

[0068] Specifically, the connecting joint 251 may include a self-closing quick-plug joint 253 and a drain bolt 254. When the oil pipe 25 is connected to the engine 30, the drain bolt 254 is connected to the oil pan, and the self-closing quick-plug joint 253 is connected between the oil pipe 25 and the drain bolt 254. When the oil pipe 25 is inserted into the self-closing quick-plug joint 253, the self-closing quick-plug joint 253 can be automatically locked, and the connection between the oil pipe 25 and the self-closing quick-plug joint 253 can be achieved without the use of tools, thereby reducing the assembly complexity of the measuring device 100 and reducing the use cost of the measuring device 100. In addition, the self-locking function of the self-closing quick-plug joint 253 ensures the stability and safety of the connection between the oil pipe 25 and the self-closing quick-plug joint 253, and reduces the risk of the connecting joint 251 falling off or leaking, causing the measuring device 100 to malfunction.

[0069] Furthermore, the temperature detection component can be a temperature sensor, which can be provided on the oil drain bolt 254. The temperature sensor can detect the oil temperature in the oil pipe 25 so that the controller 22 can work according to the detection information of the temperature detection component.

[0070] According to some embodiments of the present invention, Figure 1 As shown, one end of the bypass line 24 is connected to the oil filling tank 21, and the other end of the bypass line 24 is connected to the oil delivery pipe 25. The oil delivery pipe 25 is provided with a one-way valve 252. The connection between the bypass line 24 and the oil delivery pipe 25 is located on the side of the one-way valve 252 away from the oil filling pump 23.

[0071] One end of the bypass line 24 is connected to the fuel tank 21, and the other end is connected to the oil delivery pipe 25, thereby connecting the fuel tank 21 to the engine 30 through the bypass line 24. The oil delivery pipe 25 is equipped with a one-way valve 252, which allows oil to flow in one direction while preventing it from flowing in the opposite direction. Furthermore, when the oil pump 23 draws oil from the fuel tank 21 and flows it into the engine 30 through the one-way valve 252 and the oil delivery pipe 25, the oil cannot flow back into the fuel tank 21 through the one-way valve 252. The connection between the bypass line 24 and the oil delivery pipe 25 is located on the side of the one-way valve 252 away from the oil filling pump 23, so that the oil in the engine 30 can only flow back into the filling tank 21 through the bypass line 24, realizing the one-way supply of oil from the filling tank 21 to the engine 30 and the flexible return of oil in the engine 30, ensuring the stability of the oil supply, and thus helping to improve the accuracy of the oil consumption measurement results.

[0072] According to some embodiments of the present invention, Figure 1As shown, the measuring device 100 may further include: a second opening and closing valve 31, the second opening and closing valve 31 is communicatively connected to the controller 22, the second opening and closing valve 31 is used to be installed on the engine fuel filling port 32 of the engine 30, and the controller 22 is used to control the second opening and closing valve 31 to open or close the engine fuel filling port 32.

[0073] Among them, the second opening and closing valve 31 is communicatively connected with the controller 22. For example, the second opening and closing valve 31 and the controller 22 can be communicatively connected via a wiring harness, or the second opening and closing valve 31 and the controller 22 can be wirelessly connected, as long as the second opening and closing valve 31 and the controller 22 are communicatively connected. The second opening and closing valve 31 is used to be installed on the engine oil filling port 32 of the engine 30, and the controller 22 is used to control the second opening and closing valve 31 to open or close the engine oil filling port 32. When oil is filled into the engine 30, the controller 22 controls the second opening and closing valve 31 to open the engine oil filling port 32 so that the inside of the engine 30 is connected to the atmosphere, which helps to balance the air pressure inside and outside the engine 30, so that the engine oil will not be subject to excessive resistance or produce unnecessary pressure differences during the injection process, thereby ensuring that the engine oil can smoothly flow into the interior of the engine 30 to complete the oil filling process.

[0074] When the oil filling is completed, the controller 22 controls the second on-off valve 31 to close the engine oil filling port 32. The oil filling port of the engine 30 is effectively sealed, thereby blocking the direct connection between the interior of the engine 30 and the atmospheric environment, which helps to maintain the oil pressure and cleanliness inside the engine 30, and prevents external impurities or air from entering the interior of the engine 30, causing damage to the engine 30 or affecting the measurement results.

[0075] According to some embodiments of the present invention, Figure 1 As shown, the top wall of the oil filling tank 21 has an oil tank filling port 212, through which oil can be filled into the oil filling tank 21, and the oil tank filling port 212 is set on the top wall of the oil filling tank 21, which not only facilitates the oil filling operation, but also helps the engine oil to flow smoothly into the oil filling tank 21, and also helps to reduce the risk of oil splashing or overflowing during the filling process, which not only improves the stability of the oil filling process, but also reduces measurement errors.

[0076] The filling tank 21 can also be provided with a handle 215 for the user to grasp and operate. The filling tank 21 can be easily and stably lifted and placed on the weighing device 10 by grasping the handle 215, or the filling tank 21 can be removed from the weighing device 10, thereby improving the convenience and safety of the filling tank 21.

[0077] According to some embodiments of the present invention, Figure 1As shown, the measuring device 100 may further include: a third opening and closing valve 213 ; an oil drain port 214 is provided at the bottom of the oil filling tank 21 ; and the third opening and closing valve 213 is provided at the oil drain port 214 .

[0078] The bottom of the fuel tank 21 is provided with an oil drain port 214, which can be used to drain the oil in the fuel tank 21. For example, after the measurement device 100 has finished measuring, the oil in the fuel tank 21 needs to be drained. The oil drain port 214 is provided at the bottom of the fuel tank 21 to ensure that the oil in the fuel tank 21 can be drained as completely as possible during the draining process, thereby avoiding any residual oil. A third on-off valve 213 is provided at the oil drain port 214. The opening or closing of the oil drain port 214 can be controlled by opening or closing the third on-off valve 213. When the oil needs to be drained, the third on-off valve 213 is opened to open the oil drain port 214 to drain the oil in the fuel tank 21. When the oil does not need to be drained, the third on-off valve 213 remains closed, ensuring the sealing of the fuel tank 21 and preventing oil leakage.

[0079] The oil drain port 214 and the third opening and closing valve 213 arranged at the bottom of the filling tank 21 together constitute the discharge system of the filling tank 21, which not only helps to discharge and replace the engine oil, but also improves the sealing and safety of the filling tank 21, thereby indirectly improving the measurement accuracy of the measuring equipment 100.

[0080] According to some embodiments of the present invention, Figure 2 As shown, the controller 22 may include: an oil filling button, an oil draining button, and a time adjustment button 225. The controller 22 is further configured to control the oil filling pump 23 to start according to the trigger information of the oil filling button;

[0081] The controller 22 is further configured to control the first on-off valve 241 to open according to the triggering information of the oil release button;

[0082] The controller 22 is further configured to control the first on-off valve 241 to close according to the triggering information of the time adjustment button 225 .

[0083] The controller 22 may include an oil filling button, an oil draining button, and a time adjustment button 225. The user can press the oil filling button, the oil draining button, and the time adjustment button 225. When the user presses the oil filling button, the controller 22 can receive trigger information from the oil filling button, and the controller 22 controls the oil filling pump 23 to start according to the trigger information of the oil filling button. The oil filling pump 23 begins to pump the oil in the filling tank 21 into the engine 30. When the liquid level detection component 211 detects that the oil level in the filling tank 21 reaches a preset liquid level, the liquid level detection component 211 feeds back the detection information to the controller 22, and the controller 22 controls the oil filling pump 23 to stop working according to the detection information.

[0084] When the user presses the oil drain button, the controller 22 can receive the trigger information of the oil drain button, and the controller 22 controls the first opening and closing valve 241 to open according to the trigger information of the oil drain button, so that the bypass line 24 connects the filling tank 21 and the oil pipe 25, so that the oil in the engine 30 can flow back to the filling tank 21.

[0085] When the user presses the time adjustment button 225, the controller 22 receives trigger information from the time adjustment button 225. Based on the trigger information, the controller 22 controls the first on-off valve 241 to close, thereby blocking the fuel tank 21 and the fuel pipe 25, thereby stopping the engine 30 from draining fuel. It should be noted that the time adjustment button 225 can be used to set the duration of the fuel draining process for the engine 30. The user sets the duration of the fuel draining process by pressing the time adjustment button 225. When the set duration is reached, the controller 22 controls the first on-off valve 241 to close, thereby stopping the engine 30 from draining fuel.

[0086] In this way, oil injection and oil discharge can be accurately controlled, unnecessary oil waste can be reduced, and measurement errors can be reduced. By automatically managing the status of the oil injection pump 23 and the first opening and closing valve 241 through the controller 22, the safety risks caused by human operating errors can be reduced, and the measurement accuracy of the measuring device 100 can be further improved.

[0087] Furthermore, the controller 22 may also include an intelligent meter 226, which can accurately set the oil drain temperature, etc. The intelligent meter 226 can also record the weighing data of the weighing device 10 to simplify the measurement data recording process, thereby improving the test efficiency and accuracy of the measuring device 100. As an example of this application, Figure 2 As shown, the controller 22 also includes: a power button 220, the oil filling button may include a first oil filling button 221 and a second oil filling button 222, and the oil drain button may include a first oil drain button 223 and a second oil drain button 224. During the measurement process, when the engine 30 is filled with oil for the first time, the first oil filling button 221 is pressed, and when the engine 30 is filled with oil for the second time, the second oil filling button 222 is pressed. When the engine 30 is drained from the oil for the first time, the first oil drain button 223 is pressed, and when the engine 30 is drained from the oil for the second time, the second oil drain button 224 is pressed.

[0088] According to some embodiments of the present invention, Figure 1 As shown, the measuring device 100 further includes a running device 40 , and the weighing device 10 is placed on the running device 40 .

[0089] Among them, the walking device 40 can be constructed as a mobile vehicle. Specifically, the walking device 40 can include a placement platform 41, moving wheels 42, and a push rod 43. The placement platform 41 is used to place the weighing device 10. The walking device 40 moves through the moving wheels 42. The user pushes the walking device 40 by grasping the push rod 43, and can move the weighing device 10 to the vicinity of the engine 30 to measure the oil consumption of the engine 30.

[0090] Specifically, the size and shape of the placement platform 41 can be reasonably set according to the size and shape of the weighing device 10. For example, the upper surface of the placement platform 41 can be constructed as a plane, and the upper surface of the placement platform 41 can be provided with an anti-slip texture or an anti-slip pad, so that the weighing device 10 can be placed stably on the placement platform 41 to prevent the weighing device 10 from sliding or overturning, thereby improving the safety and stability of the weighing device 10.

[0091] By providing a moving wheel 42 on the walking device 40, the walking device 40 can be moved flexibly so that the weighing device 10 can meet the working requirements of different positions, and the moving wheel 42 can be provided with a locking mechanism 44, which can be a brake pad. The locking mechanism 44 can brake the moving wheel 42 to achieve the braking effect of the walking device 40, so that the walking device 40 can be fixed at the working position to prevent the walking device 40 from accidentally sliding, thereby reducing the risk of the measurement process being interrupted or terminated, and thus improving the stability and reliability of the measuring equipment 100.

[0092] The push rod 43 can be reasonably set according to ergonomic principles to facilitate user grasping and operation. The user can grasp the push rod 43 and push the walking device 40 to move the walking device 40 to the vicinity of the engine 30, so as to facilitate the normal subsequent measurement process.

[0093] By using the placement platform 41, the moving wheel 42 and the push rod 43 in conjunction with each other, the weighing device 10 can be placed stably and moved flexibly, which not only improves the measurement efficiency and flexibility of the measuring equipment 100, but also provides users with a convenient operating experience.

[0094] Furthermore, the measurement process of the measuring device 100 is as follows:

[0095] Before measurement, the weighing device 10 and the filling device 20 are moved near the engine 30 via the travel device 40. The travel device 40 is locked via the locking mechanism 44 to ensure that the travel device 40 stably supports the weighing device 10 and the filling device 20. The filling tank 21 is then connected to the engine 30 via the connecting joint 251, the oil delivery pipe 25, the filling pump 23, and the bypass line 24. The filling tank 21 is then filled with the corresponding type and volume of engine oil for the engine 30 through the tank filling port 212. Before measurement, the first on-off valve 241, the second on-off valve 31, and the third on-off valve 213 are all normally closed.

[0096] Filling the engine 30 with oil for the first time: Press the power button 220 to power on the measuring device 100, and press the first oil filling button 221 so that the controller 22 controls the oil filling pump 23 to start according to the trigger information of the first oil filling button 221. The oil filling pump 23 starts to pump the oil in the filling tank 21 into the engine 30 through the one-way valve, the oil delivery pipe 25, and the connecting joint 251. At this time, the first on-off valve 241 is closed to prevent the oil from flowing back into the filling tank 21 from the bypass line 24. The controller 22 also controls the second on-off valve 31 is opened to connect the engine 30 with the atmosphere to balance the air pressure inside and outside the engine 30, thereby ensuring that the engine oil can flow smoothly into the engine 30. When the liquid level detection component 211 detects that the oil height in the filling tank 21 reaches the preset liquid level, the liquid level detection component 211 feeds back the detection information to the controller 22. The controller 22 controls the oil filling pump 23 to stop working according to the detection information of the liquid level detection component 211. At this time, the controller 22 controls the second on-off valve 31 to close, completing the first oil filling into the engine 30.

[0097] The first oil draining of the engine 30: the engine 30 is controlled to stop after completing the warm-up, and the crankshaft of the engine 30 is controlled to rotate so that the camshaft of the engine 30 moves to the timing point position, and the time adjustment button 225 is pressed to set the oil draining time of the engine 30 (the first preset time), and the oil draining temperature (the preset temperature value) is set through the smart instrument 226, and then the first oil draining button 223 is pressed. When the temperature detection component detects that the oil temperature in the oil delivery pipe 25 reaches the preset temperature value, the temperature detection component feeds back the detection information to the controller 22, and the controller 22 controls the first on-off valve 241 to open for the first preset time to allow the oil in the engine 30 to flow into the filling tank 21. When the first preset time ends, the controller 22 controls the first on-off valve 241 to close to stop the oil draining of the engine 30, and the controller 22 controls the weighing device 10 to weigh and record the first weighing value G1 of the weighing device 10.

[0098] Filling the engine 30 with oil for the second time: Press the second oil filling button 222 to enable the controller 22 to control the oil filling pump 23 to start according to the trigger information of the second oil filling button 222. The oil filling pump 23 starts to pump the oil in the filling tank 21 into the engine 30 through the one-way valve, the oil delivery pipe 25, and the connecting joint 251. At this time, the first on-off valve 241 is closed to prevent the oil from flowing back into the filling tank 21 from the bypass line 24. The controller 22 also controls the second on-off valve 31 to open, so that the inside of the engine 30 is connected to the atmosphere to balance the inside and outside of the engine 30. The air pressure is increased to ensure that the engine oil can flow smoothly into the engine 30. When the liquid level detection component 211 detects that the oil height in the filling tank 21 reaches the preset liquid level, the liquid level detection component 211 feeds back the detection information to the controller 22. The controller 22 controls the oil filling pump 23 to stop working according to the detection information of the liquid level detection component 211. At this time, the controller 22 controls the second on-off valve 31 to close, completing the second oil filling into the engine 30. The controller 22 also controls the weighing device 10 to weigh and record the second weighing value G2 of the weighing device 10.

[0099] The engine 30 is drained after running for the second preset time: After the engine 30 runs for the second preset time and consumes part of the oil, the engine 30 stops running, and the crankshaft of the engine 30 is controlled to rotate so that the camshaft of the engine 30 moves to the timing point position. The time adjustment button 225 is pressed to set the oil draining time of the engine 30 (the first preset time), and the oil draining temperature (the preset temperature value) is set through the smart meter 226. Then, the second oil draining button 224 is pressed. When the temperature detection component detects that the oil temperature in the oil delivery pipe 25 reaches the preset temperature value, the temperature detection component feeds back the detection information to the controller 22. The controller 22 controls the first on-off valve 241 to open for the first preset time to allow the oil in the engine 30 to flow into the filling tank 21. When the first preset time ends, the controller 22 controls the first on-off valve 241 to close to stop draining the oil from the engine 30, and the controller 22 controls the weighing device 10 to weigh and record the third weighing value G3 of the weighing device 10.

[0100] Among them, G1-G2 is the volume of oil injected before the engine 30 starts working, G3-G2 is the volume of oil remaining in the engine 30 after the engine 30 has worked for the second preset time, G=(G1-G2)-(G3-G2), and G is the oil consumption of the engine 30.

[0101] Thus, by measuring the oil consumption of the engine 30 using the measuring device 100 of the present application, the oil consumption of the engine 30 can be accurately calculated. There is no risk of oil splashing during the measurement process, which reduces measurement errors and effectively improves the accuracy of the oil consumption measurement results of the engine 30. Furthermore, by connecting different models of engines 30 to the filling device 20, the oil consumption of engines 30 of different models can be measured, thereby greatly improving the versatility of the measuring device 100. Furthermore, the measuring device 100 has a simple structure and is easy to operate. The measurement process can be completed by operating the controller 22, which effectively improves measurement efficiency.

[0102] According to a control method for a measuring device according to an embodiment of the present invention, the measuring device is the measuring device of the above embodiment, and the control method includes:

[0103] S1: Pour a certain volume of engine oil of the corresponding model into the fuel tank, and connect the other end of the oil pipe to the oil pan of the engine.

[0104] Among them, the oil model and oil capacity of different engine models are different. Therefore, when measuring the engine oil consumption, the oil of the corresponding engine model and capacity should be injected into the filling tank, and the other end of the oil pipe should be connected to the oil pan of the engine to connect the filling tank and the engine, so that the oil can be injected into the engine.

[0105] S2, the controller controls the oil filling pump to work so as to inject the engine oil in the filling tank into the engine, and when the liquid level detection component detects that the oil height in the filling tank reaches a preset liquid level, the controller controls the oil filling pump to stop working.

[0106] Among them, the controller is communicatively connected with the oil filling pump, the liquid level detection component, the first opening and closing valve, and the second opening and closing valve. When the oil filling button is pressed, the controller can control the oil filling pump to work according to the trigger information of the oil filling button to inject the engine oil in the filling tank into the engine. The controller also controls the first opening and closing valve to close to prevent the engine oil from flowing back into the filling tank from the bypass line. The controller also controls the second opening and closing valve to open to balance the air pressure inside and outside the engine to ensure that the engine oil can flow smoothly into the engine. When the liquid level detection component detects that the oil height in the filling tank reaches the preset liquid level height, the liquid level detection component will feed back the detection information to the controller. The controller controls the oil filling pump to stop working according to the detection information of the liquid level detection component, and the controller also controls the second opening and closing valve to complete the oil filling of the engine.

[0107] S3, when the temperature detecting element detects that the temperature of the oil in the oil pipe reaches a preset temperature value, the controller controls the first on-off valve to open for a first preset time to allow the oil in the engine to flow into the fuel tank, and controls the weighing device to weigh and record the first weighing value G1 of the weighing device.

[0108] Among them, the first preset time can be a period of time (the duration of the oil draining process of the above-mentioned engine), and the controller is communicatively connected with the temperature detection component, the first opening and closing valve, and the weighing device. The temperature detection component can be used to detect the oil temperature in the oil pipe. When the temperature detection component detects that the oil temperature in the oil pipe reaches the preset temperature value, the temperature detection component will feed back the detection information to the controller. The controller opens the first opening and closing valve according to the detection information of the temperature detection component to connect the bypass line to the fuel tank and the fuel pipe, and the first opening and closing valve is opened for the first preset time to allow the oil in the engine to flow into the fuel tank. The controller controls the first opening and closing valve to close and ends the oil draining of the engine. At this time, the controller controls the weighing device to weigh and record the first weighing value G1 of the weighing device.

[0109] S4, the controller controls the oil filling pump to inject the oil in the filling tank into the engine, and when the liquid level detection component detects that the oil height in the filling tank reaches the preset liquid level, the controller controls the oil filling pump to stop working, controls the weighing device to weigh and records the second weighing value G2 of the weighing device.

[0110] Among them, after the oil in the engine flows back to the filling tank, the controller controls the filling pump to work again to re-inject the oil in the filling tank into the engine, and when the liquid level detection component detects that the oil height in the filling tank reaches the preset liquid level, the controller controls the filling pump to stop working, completes the secondary oil filling of the engine, controls the weighing device to weigh and records the second weighing value G2 of the weighing device.

[0111] S5, controlling the engine to stop operating after the engine operates for a second preset time.

[0112] The second preset time may be a period of time. After the engine completes secondary oil injection, the engine is controlled to start working to consume the oil. After the engine has worked for the second preset time, the engine is controlled to stop working.

[0113] S6, when the temperature detecting element detects that the temperature of the oil in the oil pipe reaches a preset temperature value, the controller controls the first on-off valve to open for a first preset time to allow the oil in the engine to flow into the fuel tank, and controls the weighing device to weigh and record a third weighing value G3 of the weighing device.

[0114] Among them, after the engine stops working, when the temperature detection component detects that the oil temperature in the oil pipe reaches a preset temperature value, the temperature detection component will feed back the detection information to the controller. The controller opens the first on-off valve according to the detection information of the temperature detection component to connect the bypass pipeline to the fuel tank and the oil pipe, and the first on-off valve is opened for a first preset time to allow the engine oil to flow into the fuel tank. The controller controls the first on-off valve to close and ends the oil draining of the engine. At this time, the controller also controls the weighing device to weigh and record the third weighing value G3 of the weighing device.

[0115] S7, calculating the oil consumption G according to the formula G=(G1-G2)-(G3-G2).

[0116] Among them, from the above-mentioned oil filling and draining steps, it can be concluded that G1-G2 is the volume of oil injected before the engine starts working, and G3-G2 is the volume of oil remaining in the engine after the engine has been running for the second preset time. Then G=(G1-G2)-(G3-G2), and G is the oil consumption of the engine.

[0117] According to some embodiments of the present invention, the preset temperature value may be 85°-95°, and the first preset time may be 26 min-35 min.

[0118] Among them, the preset temperature value can be 85°-95°, for example: the preset temperature value can be 85°, 90°, 95° and other values. When the oil temperature is 85°-95°, the fluidity, lubricity and sealing of the oil are better, which helps to reduce the measurement error caused by changes in the oil state. Therefore, when the oil temperature is 85°-95°, draining the engine can relatively reduce the fluctuation of oil consumption caused by temperature changes, thereby improving the accuracy and reliability of the measurement.

[0119] The first preset time may be 26 minutes to 35 minutes, and may be a value such as 26 minutes, 30 minutes, or 35 minutes, to ensure that the engine oil flows into the refueling tank as much as possible, thereby reducing measurement errors caused by residual oil. Furthermore, the first preset time needs to be reasonably set based on the engine model, oil type, engine oil capacity, and actual conditions, thereby minimizing measurement errors.

[0120] According to some embodiments of the present invention, when the temperature detecting element detects that the temperature of the engine oil in the oil delivery pipe reaches a preset temperature value, the controller controls the first on-off valve to open for a first preset time to allow the engine oil in the engine to flow into the fuel tank, and controls the weighing device to weigh and record a first weighing value G1 of the weighing device, including:

[0121] The engine is controlled to complete warm-up before stopping, and the engine crankshaft is controlled to rotate so that the engine camshaft moves to the timing point position.

[0122] Among them, the engine is controlled to complete the warm-up before being shut down. The warm-up can increase the oil temperature, reduce the viscosity, and enhance the fluidity, so that the oil can be more evenly distributed in various parts of the engine, thereby more accurately reflecting the engine's oil consumption. When the oil temperature is low, the high viscosity of the oil may cause the oil to remain inside the engine and cannot completely flow back to the oil pan, resulting in inaccurate oil volume and measurement errors. After the warm-up, the oil temperature increases, the viscosity decreases, and the fluidity enhances, so it can fully flow back to the oil pan, thereby reducing measurement errors and improving the accuracy of the engine oil consumption measurement results.

[0123] And controlling the rotation of the engine's crankshaft to move the engine's camshaft to the timing point position can ensure that the crankshaft, piston connecting rod, intake and exhaust valves, camshaft and other components inside the engine are all stopped at the same position, thereby reducing the residual oil on the crankshaft, piston connecting rod, intake and exhaust valves, camshaft and other components, thereby reducing measurement errors and improving the accuracy of the engine oil consumption measurement results.

[0124] According to some embodiments of the present invention, controlling the engine to stop operating after the engine has operated for a second preset time includes:

[0125] Control the engine's crankshaft rotation to move the engine's camshaft to the timing point position.

[0126] Among them, controlling the rotation of the engine's crankshaft to move the engine's camshaft to the timing point position can ensure that the crankshaft, piston connecting rod, intake and exhaust valves, camshaft and other components inside the engine are all stopped in the same position, thereby reducing the residual oil on the crankshaft, piston connecting rod, intake and exhaust valves, camshaft and other components, and further reducing the measurement error, so as to further improve the accuracy of the engine oil consumption measurement results.

[0127] Furthermore, the measuring process of the measuring device is:

[0128] Before measurement, the weighing device and filling device are moved near the engine using the travel device. The travel device is locked using the locking mechanism to ensure that the travel device stably supports the weighing device and filling device. The filling tank is connected to the engine via a connecting joint, oil pipeline, filling pump, and bypass line. Then, the filling tank is filled with oil of the appropriate model and capacity of the engine through the tank filling port. Before measurement, the first, second, and third on-off valves are all normally closed.

[0129] The first time to fill oil into the engine: press the power button to power on the measuring equipment, press the first oil filling button so that the controller controls the oil filling pump to start according to the trigger information of the first oil filling button, and the oil filling pump begins to pump the engine oil in the fuel tank into the engine through the one-way valve, oil pipe, and connecting joint. At this time, the first on-off valve is in a closed state to prevent the engine oil from flowing back into the fuel tank from the bypass line. The controller also controls the second on-off valve to open to connect the engine with the atmosphere to balance the air pressure inside and outside the engine, thereby ensuring that the engine oil can flow smoothly into the engine. When the liquid level detection component detects that the oil height in the fuel tank reaches the preset liquid level height, the liquid level detection component will feed back the detection information to the controller. The controller controls the oil filling pump to stop working according to the detection information of the liquid level detection component. At this time, the controller controls the second on-off valve to close, completing the first time to fill oil into the engine.

[0130] The first oil draining of the engine: control the engine to complete the warm-up before stopping, and control the engine crankshaft to rotate so that the engine camshaft moves to the timing point position, press the time adjustment button to set the engine oil draining time (first preset time), set the oil draining temperature (preset temperature value) through the intelligent instrument, and then press the first oil draining button. When the temperature detection component detects that the oil temperature in the oil pipe reaches the preset temperature value, the temperature detection component will feed back the detection information to the controller, and the controller controls the first on-off valve to open for the first preset time to allow the engine oil to flow into the fuel tank. When the first preset time ends, the controller controls the first on-off valve to close to stop the engine oil draining, and the controller controls the weighing device to weigh and record the first weighing value G1 of the weighing device.

[0131] The second time of filling oil into the engine: press the second oil filling button so that the controller controls the oil filling pump to start according to the trigger information of the second oil filling button. The oil filling pump starts to pump the engine oil in the filling tank into the engine through the one-way valve, oil pipe, and connecting joint. At this time, the first on-off valve is in a closed state to prevent the engine oil from flowing back into the filling tank from the bypass pipe. The controller also controls the second on-off valve to open so that the engine is connected to the atmosphere to balance the air pressure inside and outside the engine, thereby ensuring that the engine oil can flow smoothly into the engine. When the liquid level detection component detects that the oil height in the filling tank reaches the preset liquid level height, the liquid level detection component will feed back the detection information to the controller. The controller controls the oil filling pump to stop working according to the detection information of the liquid level detection component. At this time, the controller controls the second on-off valve to close, completing the second time of filling oil into the engine. The controller also controls the weighing device to weigh and record the second weighing value G2 of the weighing device.

[0132] The engine is drained after running for the second preset time: after the engine has run for the second preset time and consumed part of the oil, the engine stops working, and the engine crankshaft is controlled to rotate so that the engine camshaft moves to the timing point position, press the time adjustment button to set the engine drain time (first preset time), set the drain temperature (preset temperature value) through the intelligent instrument, and then press the second drain button. When the temperature detection component detects that the oil temperature in the oil pipe reaches the preset temperature value, the temperature detection component will feed back the detection information to the controller, and the controller controls the first on-off valve to open for the first preset time to allow the engine oil to flow into the fuel tank. When the first preset time ends, the controller controls the first on-off valve to close to stop draining the engine, and the controller controls the weighing device to weigh and record the third weighing value G3 of the weighing device.

[0133] Among them, G1-G2 is the volume of oil injected before the engine starts working, G3-G2 is the volume of oil remaining in the engine after the engine starts working for the second preset time, G=(G1-G2)-(G3-G2), and G is the oil consumption of the engine.

[0134] Therefore, by measuring engine oil consumption using the measuring device of the present application, engine oil consumption can be accurately calculated. There is no risk of oil splashing during the measurement process, which reduces measurement errors and effectively improves the accuracy of engine oil consumption measurement results. Furthermore, by connecting different engine models to the filling device, the oil consumption of engines of different models can be measured, greatly enhancing the versatility of the measuring device. Furthermore, the measuring device has a simple structure and is easy to operate. The measurement process can be completed by operating the controller, effectively improving measurement efficiency.
