[0002] The impact of DPF on engine oil after high mileage and the evaluation of DPF degradation index are important research directions in the field of vehicle exhaust aftertreatment.

At the same time, the overall durability of the after-treatment system will also be the focus of attention, including the coordination between various components, fatigue durability, etc. In addition to the evaluation of the performance of the DPF itself, future research will pay more attention to the overall performance evaluation of the after-treatment system, including the matching between the DPF and the engine, the reliability and durability of the after-treatment system, etc. This will help improve the vehicle's mileage and emission performance.

After that, the vehicle engine oil is replaced. In order to ensure the standardization of the subsequent measurement of the oil dilution amount, the oil level must reach the specified position height, and the operating condition test is carried out after the specified fuel is uniformly replaced. When the vehicle mileage is 0km, the oil state information is first collected in real time, and the oil level height purity is unified and uniformly recorded as the oil state information. After that, other state information of the current vehicle, such as vehicle load information, etc., needs to be collected before the test, and it is determined whether the vehicle load information meets the load condition of 500kg. In some optional embodiments, sandbags or dummies can be used to increase the vehicle weight, and after the above conditions are met, Start the vehicle DPF operating condition test, first start the current vehicle and test the vehicle according to multiple groups of preset test conditions, wherein the multiple groups of preset test conditions include at least front conditions and rear conditions, and recycle the preset test conditions after completing the front conditions and rear conditions in sequence, wherein the front conditions include at least five front test sub-conditions, and the rear conditions include at least five rear test sub-conditions. It should be noted that the above conditions include the operating conditions of most vehicles during driving on urban roads, such as the vehicle speed is limited to 60km / h, the vehicle frequently switches gears to complete start-stop operations, etc., so that the test data is more in line with the daily driving of drivers on urban roads, thereby improving the accuracy of the high mileage degradation evaluation value in the present invention.
[0049] In addition, for the specific description of the five front test sub-conditions and the five rear test sub-conditions, the current vehicle is started and idled for 5 seconds, then the vehicle is shifted into first gear and driven at a speed of 6 km / h for 24 seconds, then braked to stop and idled for 3 seconds to complete the first front test sub-condition;
[0050] Start the vehicle within 10 seconds and accelerate it to 40 km / h, then drive at a constant speed for 30 seconds, accelerate to 55 km / h within 40 seconds, decelerate to 20 km / h within 35 seconds, accelerate to 40 km / h within 10 seconds, then drive at a constant speed of 40 km / h in third gear for 55 seconds, stop within 10 seconds and idle for 40 seconds, completing the second front test sub-condition;
[0051] Start accelerating to 50 km / h within 40 seconds, then drive at a constant speed of 50 km / h in third gear for 30 seconds, decelerate to a stop within 14 seconds, and idle for 10 seconds to complete the third front test sub-condition;

[0053] Start accelerating to 20 km / h within 10 seconds, then decelerate to 4 km / h within 10 seconds, accelerate to 20 km / h within 15 seconds, decelerate to stop within 10 seconds, and then idle for 72 seconds, completing the fifth front test sub-condition;
[0054] Start accelerating to 50 km / h within 50 seconds, then decelerate to a stop within 35 seconds and idle for 20 seconds to complete the first post-test sub-condition;
[0055] Start accelerating to 35 km / h within 28 seconds, then drive at a constant speed of 35 km / h in third gear for 73 seconds, decelerate to a stop within 5 seconds, and then idle for 35 seconds to complete the second post-test sub-condition;
[0056] Start accelerating to 15 km / h within 5 seconds, then drive at a constant speed of 15 km / h in second gear for 35 seconds, decelerate to a stop within 5 seconds, then idle for 70 seconds, completing the third post-test sub-condition;
[0057] Start and accelerate to 40 km / h within 20 seconds, then drive at a constant speed of 40 km / h in the third gear for 60 seconds, decelerate to 10 km / h within 15 seconds, accelerate to 35 km / h within 15 seconds, then drive at a constant speed of 35 km / h in the third gear for 110 seconds, decelerate to 5 km / h within 15 seconds, accelerate to 25 km / h within 80 seconds, decelerate to stop within 10 seconds, and idle at the spot for 20 seconds to complete the fourth post-test sub-condition;

[0059] Step S03, obtaining mileage information in real time, and collecting the oil status information of the current vehicle as evaluation information of the current vehicle after the mileage information meets the preset mileage.
[0060] In specific implementation, when the vehicle is in the process of implementing the pre-operating condition and post-operating condition cycles, the mileage information is obtained in real time, and when the mileage information meets 5000km and 10000km respectively, the current vehicle's oil level is obtained first, and then the oil is collected and the residual carbon content of the oil is tested, and then the oil status information is uniformly determined as the evaluation information of the current vehicle, and the oil is tested and analyzed. The specific test results must be based on the oil's own dynamic viscosity of 100℃, 6.7cst or above, and the residual carbon increase compared to the initial test is less than 2.1w%.

[0062] Embodiment 2
[0063] See also Figure 2 , which shows a post-processing high mileage degradation evaluation method in a second embodiment of the present invention, and the method specifically includes steps S11 to S14.
[0064] Step S11, collect the current vehicle status information, the status information at least includes oil status information, load information and mileage information, and determine whether the current vehicle load information meets the preset conditions. If so, execute steps S12 and S13.
[0065] Step S12, implement the plateau driving mode, and drive 5700 km based on the altitude condition of 2800m and the average speed of 25km / h.
[0066] It should be noted that the working condition test time in this step accounts for 75% of the total plateau driving test time.
[0067] In the specific implementation, it is necessary to select a flat road with an altitude of 2800m for the working condition test, and according to the working condition test distance of the whole process of 10000km, take 57% of the whole working condition test distance as the working condition test distance of this step, and complete 5700km at an average vehicle speed of 25km / h. It should be noted that this working condition test process includes idling time, and the idling time accounts for 32% of the total duration of this working condition test. In some optional embodiments, it can be idling after engaging the first gear or idling the vehicle in neutral. In this case, the vehicle speed can be adjusted arbitrarily, but it must be ensured that the average vehicle speed is 25km / h after the vehicle has driven 5700km. The advantage of this approach is that it can reflect the degradation of the vehicle according to different vehicle speeds at different stages, and it is not necessary to keep the vehicle at 25km / h throughout the journey, so that the final engineering test data is more in line with actual driving, and the accuracy of the working condition test is further improved.
[0068] Step S13, based on the altitude condition, driving 4300 km round trip from 2800 m to 4100 m and an average speed of 58 km / h.
[0069] It should be noted that the working condition test time in this step accounts for 25% of the total plateau driving test time;
[0070] In the specific implementation, after completing the altitude condition of step S11 on the flat road of 2800m, directly enter the round-trip driving section from 2800m to 4100m above sea level, and the working condition test distance of this section accounts for 43% of the whole working condition test distance, and ensure that the working condition test distance is traveled at an average speed of 58km / h during the 43% process, and this working condition test process also includes idling time, and the idling time accounts for 11% of the total duration of this working condition test, and is the same as some optional embodiments of step S12, which can be idling after engaging the first gear or idling the vehicle in place in neutral. In this case, the vehicle speed can be adjusted arbitrarily, but it must be ensured that the average vehicle speed is 58km / h after the vehicle has driven 4300km.
[0071] Step S14, after the final mileage reaches 10000 km, the oil level of the current vehicle is obtained, and then the oil is collected and the residual carbon content of the oil is detected as the plateau evaluation information of the current vehicle.
[0072] In specific implementation, in plateau driving mode, it is possible to obtain the vehicle's oil level after the mileage reaches 10,000 km based on vehicle mileage feedback, and collect oil to perform residual carbon content detection in the oil. In some optional embodiments of the present invention, the final mileage can also be the oil level and oil sampling detection operation in the vehicle when the mileage in the vehicle mileage information is 0 km and 5,000 km.
