Further, the step S30 specifically includes:
step S301: and acquiring target test parameters corresponding to the working condition test strategy.
It is easy to understand that the test modes and test standards of the test strategies under different working conditions are different, and therefore, target test parameters corresponding to the test strategies under the working conditions need to be obtained, and the target test parameters are calibration parameters corresponding to the test strategies under the working conditions.

It should be noted that the inlet temperature of the oxidation catalyst in the post-injection diesel engine is different from the working condition of the diesel particulate filter in the post-injection diesel engine, so that the diesel particulate filter can be in a cycle of a carbon accumulation working condition and a regeneration working condition by adjusting the inlet temperature of the oxidation catalyst, as shown in table 3.

Based on the first embodiment, the step S30 further includes:
step S301': and acquiring performance parameters of a target vehicle according to the whole vehicle test strategy, wherein the target vehicle is provided with the engine to be tested.
In this embodiment, the whole vehicle test strategy is to set an engine to be tested on a whole vehicle to operate, the test strategy further includes a whole vehicle test strategy, and performance parameters of a target vehicle are obtained according to the test strategy, wherein the performance parameters include vehicle body mass, load mass, size, wheel base and the like.
Step S302': and judging whether the target vehicle is in a full-load state or not according to the performance parameters.
It should be noted that, whether the target vehicle is in a full-load state can be determined according to parameters such as vehicle body mass and load mass in the performance parameters, and the operation load of the engine can be increased to the maximum extent only when the vehicle is in a full-load state, so that the engine oil dilution evaluation result is more reliable.
Step S303': and acquiring the ambient temperature of the road when the target vehicle is in a full-load state.
It should be noted that when the target vehicle is in a full-load state, the road environment temperature of the running road is detected, the whole vehicle test strategy includes a normal-temperature road test and a cold-zone road test, the engine oil dilution conditions at different temperatures are different, and the normal-temperature road test or the cold-zone road test is determined according to the obtained road environment.
Step S304': and when the road environment temperature meets the preset test condition, controlling the target vehicle to run under the preset road working condition.
It is easy to understand that the road environment temperature is compared with the preset test condition, the preset test condition comprises a road environment temperature threshold value, whether the target vehicle needs to perform a normal-temperature road test or a cold-zone road test can be judged through comparison, the preset road working conditions corresponding to different road environment temperatures are different, and the preset road working conditions can be a flat asphalt road or a curved mountain road and the like.
Step S305': and acquiring the running distance of the target vehicle under the preset road working condition, and extracting sample engine oil from an engine to be tested arranged on the target vehicle when the running distance reaches the preset distance.
It should be noted that, the target vehicle cannot collect the engine oil in the engine during the driving process, and the target vehicle is required to stop driving, so a preset distance needs to be set, when the driving distance of the target vehicle reaches the preset distance, the target vehicle stops driving, and sample engine oil is extracted from the engine to be tested on the target vehicle, the preset distance set by the gasoline engine is different from the preset distance set by the diesel engine, the preset distance can be understood as the sampling distance of the sample engine oil, for example, the gasoline engine samples when the target vehicle reaches the equal distance of 3000km, 5000km and 8000km, and the diesel engine samples when the target vehicle reaches the equal distance of 10000km, 20000km and 30000 km.
Further, the step S40 includes:
step S401: and acquiring the installation position of the fuel injector of the engine to be tested.
In the present embodiment, the engine oil dilution corresponding to the sample engine oil is compared with a dilution evaluation threshold, so as to evaluate the engine oil dilution risk of the engine to be tested, and the dilution evaluation threshold is related to the installation position of the injector, where the installation position of the injector includes a side injector and a top injector.
Step S402: and determining a dilution evaluation threshold according to the installation position of the oil sprayer.
In this embodiment, the engines passing the bench test have different dilution evaluation thresholds, for example, the dilution evaluation threshold of the side injector corresponding to condition 1 in table 1 is 6%, and the dilution evaluation threshold of the overhead injector is 5%.
Step S403: comparing the engine oil dilution corresponding to the sample engine oil to the dilution evaluation threshold.
In particular implementations, after the engine oil dilution corresponding to the sample engine oil is obtained, the engine oil dilution corresponding to the sample engine oil is compared in magnitude to a dilution evaluation threshold.
Step S404: and evaluating the sample engine oil according to the comparison result to obtain an engine oil dilution risk evaluation result of the engine to be tested.
It should be noted that if the dilution of the sample engine oil is greater than or equal to the dilution evaluation threshold, it is determined that the engine to be tested has an engine oil dilution risk, and if the sparsity of the sample engine oil is less than the dilution evaluation threshold, it is determined that the engine to be tested does not have an engine oil dilution risk.
