Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to an engine lubricating oil temperature rising system, a control method thereof, and a vehicle. Background Art

[0002] Lubricating oil is an essential substance in the engine system, mainly used for lubricating relevant components in the engine to reduce component wear. The lubricating oil can be engine oil.

[0003] The viscosity of engine oil is greatly affected by temperature. In winter in plateau and high altitude areas, extremely cold weather of -40°C may occur. In such extreme environments, the engine often has problems such as insufficient oil supply and poor lubrication due to too low engine oil temperature and high engine oil viscosity. Over time, it will lead to serious wear of the moving parts of the engine, and in more severe cases, it will lead to complete damage of the engine. Therefore, it is very important to heat up the engine oil.

[0004] In the prior art, most of the heating devices for the engine oil in the oil pan need to use the heat generated by the exhaust pipe to assist in heating the engine oil in the oil pan after starting the engine. However, the engine oil temperature is still close to the very low ambient temperature before the engine starts, resulting in a difficult engine starting process and inability to lubricate the engine during startup, thereby affecting the service life and reliability of the engine. Summary of the Invention

[0017] Based on the above concept, the technical solution adopted by the present invention is:

[0039] Embodiment 1

[0040] This embodiment provides an engine lubricating oil temperature rising system, which can pre-heat the lubricating oil under the condition of low ambient temperature, reduce the difficulty of engine starting, extend the service life of the engine, and improve the reliability of the engine.

[0041] As Figure 1 shown, the engine lubricating oil temperature rising system includes an active temperature rising device, a coolant circulation temperature rising device and a controller.

[0042] Among them, the active temperature rising device includes: a power supply 11, a switch 12 and a heating component 13. The heating component 13 is connected to the power supply 11 through the switch 12, and the power supply 11 provides electrical energy. The heating component 13 is located at the bottom of the oil pan 10 of the engine and can be used to heat the lubricating oil in the oil pan 10 to increase the temperature of the lubricating oil, thereby reducing the viscosity of the lubricating oil.

[0043] The coolant circulation heating device includes a driving pump 21, a cooling pipeline 22, a first one-way valve 23 and a second one-way valve 24. The driving pump 21 is used to drive the coolant in the cooling pipeline 22 to flow. The cooling pipeline 22 is communicated with the cooling system of the engine, and part of the cooling pipeline 22 is installed on the inner wall of the oil pan 10 and is used to heat the lubricating oil in the oil pan 10. The driving pump 21, the first one-way valve 23 and the second one-way valve 24 are all located outside the oil pan 10. The first one-way valve 23 is arranged at the outlet of the driving pump 21, and the first one-way valve 23 is only used for the coolant flowing out of the driving pump 21 to flow into the cooling pipeline 22 in the oil pan 10, and the coolant in the cooling pipeline 22 in the oil pan 10 cannot flow to the driving pump 21 through the first one-way valve 23. The second one-way valve 24 is arranged at the inlet of the driving pump 21, and the second one-way valve 24 is only used for the coolant in the cooling pipeline 22 in the oil pan 10 to flow to the driving pump 21, and the coolant at the driving pump 21 cannot flow to the cooling pipeline 22 in the oil pan 10 through the second one-way valve 24, so that the one-way flow of the coolant can be realized. When both the first one-way valve 23 and the second one-way valve 24 are closed, the coolant in the cooling pipeline 22 located between the two one-way valves and partially located in the oil pan 10 is stationary and does not flow. It should be noted that the cooling system of the engine can absorb the heat of the exhaust pipe, so that after the engine is started, the exhaust pipe can heat the coolant in the cooling pipe, so that the temperature of the coolant in the cooling pipe rises and heats the lubricating oil in the oil pan 10.

[0044] The above-mentioned controller is respectively and controllably connected to the switch 12, the first one-way valve 23 and the second one-way valve 24. The controller is used to control the switch 12 to open and control the first one-way valve 23 and the second one-way valve 24 to close when the temperature of the lubricating oil in the oil pan 10 is less than the first preset temperature; when the temperature of the lubricating oil in the oil pan 10 is greater than or equal to the first preset temperature and less than the second preset temperature, the controller is also used to control the switch 12, the first one-way valve 23 and the second one-way valve 24 to open; when the temperature of the lubricating oil in the oil pan 10 is greater than or equal to the second preset temperature, the controller is also used to control the switch 12, the first one-way valve 23 and the second one-way valve 24 to close.

[0045] The engine lubricating oil temperature rising system provided in this embodiment adopts a combination of active heating and coolant circulation heating. Before the engine starts, the lubricating liquid in the oil pan 10 is heated by the active temperature rising device first. After the temperature rises to the first preset temperature, the engine is started, so that the engine will not start when the lubricating oil temperature is too low, reducing the difficulty of engine starting. After the engine starts, the active temperature rising device and the coolant circulation temperature rising device jointly heat the lubricating oil in the oil pan 10, having a relatively high temperature rising efficiency, so as to ensure that when the engine outputs power, the temperature of the lubricating oil can be relatively high, and thus have a better lubricating effect, so as to extend the service life and reliability of the engine.

[0046] Optionally, please continue to refer to Figure 1 The engine lubricating oil temperature rising system further includes a temperature sensor 14. Wherein, the temperature sensor 14 is located in the oil pan 10 and electrically connected to the power supply 11. The power supply 11 supplies electrical energy to the temperature sensor 14. The temperature sensor 14 is used to detect the temperature of the lubricating oil in the oil pan 10 for the control of the engine lubricating oil temperature rising system. In some embodiments, to ensure the control accuracy, the temperature sensor 14 detects the temperature of the lubricating oil in the oil pan 10 in real time. The temperature sensor 14 can be a structure in the prior art, and this embodiment does not limit it.

[0047] Further optionally, the temperature sensor 14 and the heating component 13 are respectively installed on the side wall of the oil pan 10 and are spaced apart in the height direction of the oil pan 10. For example, the temperature sensor 14 is located above the heating component 13 and close to the lubricating oil liquid level, and the heating component 13 is arranged close to the bottom wall of the oil pan 10. The relatively large distance between the temperature sensor 14 and the heating component 13 can prevent the heating component 13 from interfering with the accuracy of the temperature sensor 14, and the eddy current generated when the heating component 13 heats will not affect the temperature sensor 14. It should be noted that the temperature sensor 14 is arranged to avoid the cooling pipeline 22 to prevent the cooling pipeline 22 from affecting the temperature sensor 14, thereby improving the detection accuracy of the temperature sensor 14.

[0048] Still further optionally, the controller is electrically connected to the temperature sensor 14, and the controller is used to obtain the detection value of the temperature sensor 14. The engine lubricating oil temperature rising system further includes a touch display panel 3. The touch display panel 3 is connected to the power supply 11 to obtain electrical energy through the power supply 11. The controller is connected to the touch display panel 3 and controls the touch display panel 3 to display the detection value of the temperature sensor 14, that is, the temperature of the lubricating oil can be fed back to the user through the touch display panel 3 to realize the real-time monitoring of the lubricating oil temperature. Optionally, the touch display panel 3 can be the screen of the vehicle, and this embodiment does not limit it.

[0049] The specific structure of the heating component 13 can have various forms. In some alternative embodiments, the heating component 13 includes an electric heating element and a stirring element arranged in series. Among them, the electric heating element is used to heat the lubricating oil in the oil pan 10, and the stirring element is used to stir the lubricating oil in the oil pan 10 so that the lubricating oil in the oil pan 10 can be heated evenly. The heating element can be a heating plate or a heating rod, and the stirring element can be a structure in the shape of a blade. Alternatively, the stirring element can also be in a spiral shape. This embodiment does not limit this. When the heating element is a heating rod, the stirring element can be a sheet-like structure arranged on the heating rod, and the rotation of the heating rod can drive the stirring element to rotate to stir the lubricating oil.

[0050] Optionally, the cooling pipeline 22 is evenly wound around the side wall of the oil pan 10. On the one hand, it can increase the contact area with the lubricating oil to have a better heating effect, and on the other hand, it can improve the uniformity of heating the lubricating oil.

[0051] In this embodiment, aiming at the actual vehicle use requirements in winter in northern regions, plateaus, high altitudes and other areas, two heating methods of active heating and coolant circulation heating are combined. During the actual vehicle use in winter, the vehicle is first powered on. At this time, the engine is not started, and only the switch 12 is closed, and the battery is used to supply power to the heating element and the stirring element to heat the lubricating oil through the heating element. When the oil temperature in the oil pan 10 ≥ 20 °C, the engine is started and idled for 1 minute, and then the first one-way valve 23 and the second one-way valve 24 are opened to realize the combination of active heating and coolant circulation heating. When the oil temperature of the oil in the oil pan 10 ≥ 50 °C, the switch 12, the first one-way valve 23 and the second one-way valve 24 are closed. By combining active heating and coolant circulation heating, the problem of too low oil temperature before the engine starts can be solved, and the oil in the oil pan 10 can be heated together after the engine starts, improving the efficiency of oil temperature rise.

[0052] Embodiment Two

[0053] This embodiment provides a control method for an engine lubricating oil temperature rise system, which is applied to the engine lubricating oil temperature rise system in Embodiment One, as Figure 2 shown. The control method of the engine lubricating oil temperature rise system includes the following steps:

[0054] S1. Detect the temperature of the lubricating oil in the oil pan 10 of the engine;

[0055] Optionally, in some embodiments, the temperature of the lubricating oil can be detected by a temperature sensor 14 arranged in the oil pan 10, and the temperature sensor 14 and the heating component 13 are arranged at intervals in the height direction of the oil pan 10. It should be noted that in this embodiment, the temperature sensor 14 can be controlled to detect the temperature of the lubricating oil in the oil pan 10 in real time so as to be able to master the temperature of the lubricating oil in real time.

[0056] S2. When the temperature of the lubricating oil in the oil pan 10 is lower than the first preset temperature, control switch 12 is turned on, and the first one-way valve 23 and the second one-way valve 24 are controlled to be closed;

[0057] In this embodiment, since the temperature of the lubricating oil is lower than the first preset temperature, it indicates that the temperature of the environment where the vehicle is located is relatively low. Starting the engine directly is difficult and will affect the performance of the engine. In this embodiment, the lubricating oil is first heated by the active heating device to increase the temperature of the lubricating oil by a certain value. Specifically, control switch 12 is turned on to supply electrical energy to heating component 13 through power source 11, so as to heat the lubricating oil through heating component 13. At the same time, since the engine has not been started and the exhaust pipe does not heat the coolant in cooling pipe 22, the temperature of the coolant in cooling pipe 22 is approximately the ambient temperature. Therefore, it is necessary to control the first one-way valve 23 and the second one-way valve 24 to be closed to prevent the coolant in cooling pipe 22 from circulating and absorbing the heat of the lubricating oil.

[0058] S3. When the temperature of the lubricating oil rises to be greater than or equal to the first preset temperature and less than the second preset temperature, start the engine and control the first one-way valve 23 and the second one-way valve 24 to be opened;

[0059] When temperature sensor 14 detects that the temperature of the lubricating oil in oil pan 10 rises to be greater than or equal to the first preset temperature and less than the second preset temperature, it indicates that the temperature of the lubricating oil is already relatively high and its lubricating ability is strong. At this time, in order to quickly increase the temperature of the lubricating oil, the active heating device and the coolant circulation heating device can be controlled to cooperate to heat the lubricating oil, that is, start the engine and control switch 12, the first one-way valve 23 and the second one-way valve 24 to be all opened. Since the temperature of the lubricating oil has risen to the first preset temperature, starting the engine at this time, the lubricating oil can have a good lubricating effect, which is convenient for the engine to start smoothly and has little impact on the service life of the engine.

[0060] After the engine is started, the coolant in cooling pipe 22 is heated through the exhaust pipe of the engine, and the coolant is driven by drive pump 21 to circulate in cooling pipe 22 to heat the lubricating oil in oil pan 10. It should be noted that after the engine is started, the heating of the lubricating oil by the coolant circulation heating device is the main, and the heating of the lubricating oil by the active heating device is the auxiliary, realizing the recycling of energy for energy conservation. In this embodiment, heating component 13 can be connected to the controller, and the controller can control the heating power of heating component 13. Through the mutual cooperation of the active heating device and the coolant circulation heating device, the temperature of the lubricating oil can be quickly heated to the preset value (i.e., the second preset temperature).

[0061] S4. When the temperature of the lubricating oil rises to be greater than or equal to the second preset temperature, control switch 12, the first one-way valve 23 and the second one-way valve 24 are closed.

[0062] In step S4, when the temperature sensor 14 detects that the temperature of the lubricating oil rises to be greater than or equal to the second preset temperature, the lubricating oil can absorb the heat of the engine during the lubrication process, and thus can maintain a high temperature to have a better lubrication effect. Therefore, there is no need to heat it through the active heating device and the coolant circulation heating device anymore. Therefore, the controller controls the closing of control switch 12, the first one-way valve 23 and the second one-way valve 24.

[0063] The control method of the engine lubricating oil temperature rising system provided in this embodiment adopts a combination of active heating and coolant circulation heating. Before the engine is started, the lubricating liquid in the oil pan 10 is heated by the active heating device first. When the temperature rises to the first preset temperature, the engine is started, so that the engine will not be started when the lubricating oil temperature is too low, reducing the difficulty of starting the engine. After the engine is started, the active heating device and the coolant circulation heating device jointly heat the lubricating oil in the oil pan 10, with a high heating efficiency, so as to ensure that when the engine outputs power outward, the temperature of the lubricating oil can be relatively high, and thus have a better lubrication effect, so as to extend the service life and reliability of the engine.

[0064] Optionally, when the temperature of the lubricating oil in the oil pan 10 rises to be greater than or equal to the first preset temperature and less than the second preset temperature, the engine is started and the engine is controlled to idle for a preset duration, and after the preset duration, control switch 12, the first one-way valve 23 and the second one-way valve 24 are opened. Through the idling of the engine, the exhaust pipe is gradually heated up. Then, when the first one-way valve 23 and the second one-way valve 24 are opened, the coolant can start to circulate and absorb heat at the exhaust pipe, preventing the situation that the temperature of the exhaust pipe is relatively low and the exhaust pipe absorbs the heat of the coolant when the coolant circulates, reducing energy consumption. In some optional embodiments, the first preset temperature is 20 °C, the second preset temperature is 50 °C, and the preset duration is 1 minute.

[0065] Embodiment III

[0066] This embodiment also provides a vehicle, including an engine and the engine lubricating oil temperature rising system in Embodiment I. The heating component 13 of the engine lubricating oil temperature rising system is located at the bottom of the oil pan 10 of the engine, and part of the cooling pipeline 22 of the engine lubricating oil temperature rising system is installed on the wall of the oil pan 10. For the vehicle provided in this embodiment, the lubricating oil adopts different heating strategies at different temperature stages to quickly heat the lubricating oil on the basis of energy saving, so that the lubricating oil can lubricate the acting parts of the engine well at the initial stage when the engine outputs power.
