[0026] Example 1

[0027] Figure 1 This invention provides a flowchart of a method for determining engine oil operating conditions according to Embodiment 1. This embodiment is applicable to determining the operating conditions under which engine oil can lubricate normally. This method can be executed by an engine oil operating condition determining device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S101. Obtain the target engine oil under the test conditions and determine the density and gas content curves corresponding to the target engine oil.

[0029] The target engine oil can refer to engine oil for which the operating conditions of the engine oil are determined.

[0030] Specifically, the density and gas content curves corresponding to the target engine oil can be obtained in advance based on the characteristic tests of the target engine oil. It should be noted that different target engine oils will have different density and gas content curves. For example, the characteristic tests of the target engine oil include: first, purging the measuring chamber of the oil gas content meter, and repeating the gas content calibration three times for the target engine oil with a 100% content, with the two results being consistent. Next, calibrating the oil temperature and density by starting the engine to allow the target engine oil to flow normally in the measuring chamber without obvious air bubbles. The engine speed is then adjusted to 1500 rpm, and the throttle is controlled at 20% opening for warm-up, allowing the target engine oil temperature to reach 90°C. Then, the engine speed is adjusted to 3000 rpm, and the throttle is controlled at 100% opening. When the engine oil temperature reaches 115°C, the engine is stopped. At this time, the oil temperature, oil density, and oil gas content are measured in real time. When the target oil temperature drops to 40°C, the measurement is stopped, and the characteristic curves of oil density and oil gas content can be obtained.

[0031] S102. Based on the density and gas content curve, perform an oil condition test on the target engine into which the target oil is injected, and obtain the test results of the target oil.

[0032] The oil condition test includes a steady-state tilt test and a momentary tilt test. A steady-state tilt test refers to the target oil being tilted relative to the vehicle for an extended period while the vehicle is traveling on an incline. A momentary tilt test refers to the target oil being tilted relative to the vehicle for a short period while the vehicle is accelerating or decelerating.

[0033] Specifically, based on the density and gas content curve, steady-state tilt test and instantaneous tilt test are performed on the target engine into which the target engine oil is injected, to determine the test results of the target engine oil under steady-state tilt conditions and instantaneous tilt conditions.

[0034] For example, the step of performing an oil condition test on the target engine into which the target oil is injected includes: determining the oil test items corresponding to the target oil injected into the target engine; and performing an oil condition test on the target engine into which the target oil is injected based on the oil test items.

[0035] The engine oil test items include at least one of the target engine oil quantity, the target engine tilt direction, and the target engine speed.

[0036] Specifically, according to the pre-planned test scheme, the oil test items corresponding to the target oil are determined, and the target engine injected with the target oil is subjected to oil condition test according to the oil test items.

[0037] For example, the step of performing an oil condition test on the target engine injected with the target oil according to the oil test items includes: treating each of the multiple oil test items as a variable item in the oil condition test, and treating the other test items in the multiple test items besides the variable items as fixed items; performing an oil condition test on the target engine injected with the target oil based on the fixed items, the variable items, and the change step size corresponding to the variable items, and obtaining a single test result corresponding to the variable items; and determining that the oil condition test of the target engine injected with the target oil has been completed when all the single test results corresponding to the test items have been obtained.

[0038] It should be noted that the target oil quantity, the target engine tilt direction, and the target engine speed are all oil condition test items, and each oil condition test item is multivariable. In the technical solution of this invention, to complete a comprehensive oil condition test, one of the oil condition test items is treated as a variable item, and the other oil condition test items are treated as fixed items. Based on each fixed item, the variable item, and the corresponding change step size of the variable item, an oil condition test is performed on the target engine injected with the target oil, thereby obtaining the individual test results corresponding to the variable item. When the individual test results corresponding to all the test items are obtained, the oil condition test is considered complete.

[0039] For example, the target oil quantity includes the standard oil quantity and the minimum oil quantity, and the target engine tilt direction includes the positive X-axis, the negative X-axis, the positive Y-axis, and the negative Y-axis (for example, the present invention determines the initial tilt direction of the target engine as the positive X-axis). The target engine speed is set with an initial speed of 1000 r / min and a step size of 500 r / min, up to 5500 r / min.

[0040] For example: If the target oil quantity is defined as a variable, and the target engine tilt direction and target engine speed are both defined as fixed, then the individual test results corresponding to the target oil quantity include:

[0041] The test results are as follows: oil condition test results are based on the standard oil quantity, positive X-axis direction, and target engine speed of 1000 r / min; and oil condition test results are based on the minimum oil quantity, positive X-axis direction, and target engine speed of 1000 r / min.

[0042] If the target engine tilt direction is determined as a variable, and the target oil quantity and target engine speed are determined as fixed, then the individual test results corresponding to the target engine tilt direction include:

[0043] The test results are based on the working conditions of the X-axis positive direction, standard oil quantity, and target engine speed of 1000 r / min.

[0044] Test results of oil condition testing based on the working conditions of X-axis reversal, standard oil quantity, and target engine speed of 1000 r / min;

[0045] Test results of oil condition testing based on the working conditions of Y-axis positive direction, standard oil quantity, and target engine speed of 1000 r / min;

[0046] The test results are based on the oil condition test under the conditions of reverse Y-axis, standard oil quantity, and target engine speed of 1000 r / min.

[0047] If the target engine speed is determined as a variable, and the target oil quantity and target engine tilt direction are determined as fixed, then the individual test results corresponding to the target engine speed include:

[0048] Test results of oil condition test based on the working conditions of target engine speed of 1000 r / min, positive X-axis direction, and standard oil quantity;

[0049] Test results of oil condition test based on the target engine speed of 1500 r / min, positive X-axis direction, and standard oil quantity;

[0050] ···

[0051] The test results are based on the target engine speed of 5500 r / min, positive X-axis direction, and standard oil quantity.

[0052] At this point, the individual test results corresponding to all the test items are obtained, and the oil condition test is considered complete.

[0053] It should be noted that the target engine tilt direction may also include: starting with an initial tilt angle of 0°, increasing the tilt angle in increments of 1°, until a preset ending angle is reached.

[0054] For example, obtaining the individual test result corresponding to the variable item includes: determining the test termination condition corresponding to the variable item based on the density and gas content curve; and obtaining the individual test result corresponding to the variable item when the engine oil condition test meets the test termination condition.

[0055] The test termination conditions may include: steady-state tilt test termination conditions and instantaneous tilt test termination conditions. For example, steady-state tilt test termination conditions may include a target engine main oil passage pressure drop greater than 50 kPa, target oil gas content greater than 15%, a significant increase in the target oil content in the observation tank, and a target engine tilt angle greater than 45°. Instantaneous tilt test termination conditions may include: a target engine main oil passage pressure drop greater than 50 kPa.

[0056] Specifically, based on the density versus gas content curve, the test termination condition corresponding to the variable is determined. When performing an oil condition test on the target oil, if the test termination condition is met, the oil condition test is terminated, and the individual test result corresponding to the variable is obtained.

[0057] For example, the specific process of performing a steady-state tilt test on a target engine injected with the target engine oil can be as follows:

[0058] a) Set the initial oil level of the target engine to the standard oil quantity;

[0059] b) The initial tilt direction is set to the positive X-axis;

[0060] c) Adjust the target engine speed to 1000 r / min and fix a low torque;

[0061] d) Adjust the coolant temperature by regulating the target engine coolant thermostat to stabilize the target engine oil temperature at 100℃;

[0062] e) Wait for the target engine oil pressure and temperature to stabilize, and measure relevant parameters such as oil gas content and main oil passage pressure when the engine is in a horizontal state;

[0063] f) Increase the tilt angle in increments of 1°. At each angle, wait for the engine oil pressure and temperature to stabilize before starting the measurement. After the measurement is completed, increase the tilt angle until the steady-state tilt test termination condition is met.

[0064] g) Adjust the target engine to a horizontal state, increase the target engine speed in steps of 500 r / min until it reaches 5500 r / min, and keep the torque at a fixed low torque at each engine speed, and repeat steps e to f.

[0065] h) Tilt in the opposite direction of the X-axis, the positive direction of the Y-axis, and the opposite direction of the Y-axis, and repeat c to g;

[0066] i) Stop the engine, adjust the oil level to the lower end of the dipstick, and repeat steps b to h.

[0067] For example, the specific process of performing an instantaneous tilt test on a target engine injected with the target engine oil can be as follows:

[0068] a) Set the initial oil level of the target engine to the standard oil quantity;

[0069] b) The initial tilt direction is set to the positive X-axis;

[0070] c) Stabilize the engine oil temperature at 100°C by adjusting the engine coolant thermostat;

[0071] d) Set the engine speed to idle;

[0072] e) Wait for the target engine oil pressure and temperature to stabilize, and measure relevant parameters such as oil gas content and main oil passage pressure under horizontal conditions;

[0073] f) Increase the tilt angle in increments of 1°. After the engine oil pressure and temperature stabilize at each angle, take a measurement. Increase the tilt angle until the instantaneous tilt test termination condition is met.

[0074] g) Adjust the engine to a horizontal position, and then adjust the engine speed to 1000 r / min, 2000 r / min, and 3000 r / min in sequence. Repeat steps e to f for each engine speed.

[0075] h) Tilt in the opposite direction of the X-axis, the positive direction of the Y-axis, and the opposite direction of the Y-axis, and repeat c to g;

[0076] i) Stop the engine, then adjust the oil level to the lower mark on the dipstick, and repeat steps b to h.

[0077] S103. Determine the oil operating conditions of the target oil based on the operating condition test results of the target oil.

[0078] Specifically, based on the operating condition test results of the target engine oil, the suitable operating conditions for the target engine oil to work normally can be determined.

[0079] The technical solution of this invention involves acquiring a target engine oil under test conditions and determining its density and gas content curves. Based on these curves, an engine oil condition test is performed on a target engine injected with the target engine oil to obtain the test results. The engine oil condition test includes steady-state tilt testing and instantaneous tilt testing. Based on these test results, the engine oil condition is determined to match the target engine oil to a vehicle, thereby preventing wear on moving parts and improving the user experience.

[0080] Example 2

[0081] Figure 2 This is a flowchart of a method for determining engine oil operating conditions according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment requires an oil aging test on the target engine oil before determining the density and gas content curve corresponding to the target engine oil. Figure 2 As shown, the method includes:

[0082] S201. Obtain the target engine oil under the test conditions.

[0083] S202. Perform an oil aging test on the target oil. If the target oil has not reached the aging state, determine the density and gas content curve of the target oil.

[0084] Specifically, before determining the density and gas content curve, it is necessary to determine whether the target engine oil has reached the aging state to ensure that the target engine oil is in a normal working condition and to determine the corresponding engine oil operating conditions.

[0085] For example, the oil aging test on the target engine oil includes: warming up the target engine injected with the target engine oil under a first preset operating condition; running the target engine under a second preset operating condition when the target engine oil reaches a preset oil temperature; performing an oil dilution test on the target engine oil when the continuous running time of the target engine under the second preset operating condition is greater than or equal to a preset running time; and determining that the target engine oil has not reached the aging state when no dilution phenomenon is observed.

[0086] The first preset operating condition can refer to the target engine operating at a preset speed and a first preset throttle opening. The second preset operating condition can refer to the target engine operating at a second preset throttle opening. The preset oil temperature can be predetermined based on actual needs.

[0087] Specifically, the target engine is started, and the target engine oil is allowed to flow normally in the measuring chamber without obvious air bubbles. The target engine is then warmed up by adjusting its operating condition to the first preset condition (e.g., 1500 rpm, 20% throttle). When the target engine oil temperature reaches the preset oil temperature (e.g., 90°C), the target engine is switched to the second preset condition (e.g., 100% throttle). If the target engine runs continuously for a time greater than or equal to the preset running time (e.g., 5 hours), an oil dilution test is performed on the target engine oil (e.g., the air content of the oil in a horizontal state should not exceed 15%). If no dilution phenomenon is observed in the target engine oil, it is determined that the target engine oil has not reached the aging state.

[0088] S203. Based on the density and gas content curve, perform an oil condition test on the target engine into which the target oil is injected to obtain the oil condition test results. The oil condition test includes a steady-state tilt test and an instantaneous tilt test.

[0089] S204. Determine the oil operating conditions of the target oil based on the operating condition test results of the target oil.

[0090] In the technical solution of this invention embodiment, before determining the density and gas content curve corresponding to the target engine oil, it is necessary to conduct an engine oil aging test on the target engine oil to prevent the engine oil operating condition test from being performed on the aged target engine oil, thereby improving the accuracy of determining the engine oil operating condition of the target engine oil.

[0091] Example 3

Figure 3 As shown, the device includes: a target engine oil acquisition module 301, a working condition test result acquisition module 302, and an engine oil working condition determination module 303. Among them,

[0093] The target engine oil acquisition module 301 acquires the target engine oil under the test conditions and determines the density and gas content curves corresponding to the target engine oil.

[0094] The working condition test result acquisition module 302 is used to perform an oil working condition test on the target engine injected with the target oil based on the density and gas content curve, and obtain the working condition test result of the target oil. The oil working condition test includes a steady-state tilt test and an instantaneous tilt test.

[0095] The oil condition determination module 303 is used to determine the oil condition of the target oil based on the test results of the target oil condition.

[0096] The technical solution of this invention involves acquiring a target engine oil under test conditions and determining its density and gas content curves. Based on these curves, an engine oil condition test is performed on a target engine injected with the target engine oil to obtain the test results. The engine oil condition test includes steady-state tilt testing and instantaneous tilt testing. Based on these test results, the engine oil condition is determined to match the target engine oil to a vehicle, thereby preventing wear on moving parts and improving the user experience.

[0102] When the continuous running time of the target engine under the second preset operating condition is greater than or equal to the preset running time, an oil dilution test is performed on the target engine oil.

[0103] If the target engine oil does not show signs of dilution, it is determined that the target engine oil has not reached the aging state.

[0104] Optionally, the module for obtaining operating condition test results includes:
