Idle speed problem, diesel filter may need to be replaced in advance

Replace the diesel filter cycle?
I believe that most drivers are in accordance with the filter elements and oil products they use, 10,000 kilometers, 15,000 kilometers, and 20,000 kilometers. In general, the problem is not big, but in the case of frequent traffic jams and other long idle speeds Pay attention to replacing the diesel filter in advance.

In the case of a certain oil, the replacement cycle of the diesel filter is mainly based on the time when the engine is running. There are two criteria for diesel filter maintenance in general vehicle maintenance manuals: replacement mileage and vehicle operating time. These two parameters are actually a rough estimate of engine operating time.
Under normal operating conditions, the correspondence between vehicle running mileage and engine working time is the same, so we usually use the mileage of the vehicle to estimate the filter replacement time, and there is nothing wrong with it.
However, in the case of frequent idling such as traffic jams, the engine is also working, and the diesel fuel is continuously filtered through the diesel filter, and the odometer is unchanged at this time. The corresponding relationship between the running mileage of the vehicle and the working time of the engine is too large, the engine working time has reached the diesel filter replacement requirement, and the mileage of the vehicle is far from the replacement time.
At this time, it is not enough to maintain and replace the filter element according to the number of kilometers. It is necessary to replace the filter element in advance, otherwise the engine will be faulty. In fact, it is not difficult to understand that engineering machinery, such as digging machines, forklifts, bulldozers, etc., are all replacing diesel fuel filters according to working hours.

Under severe conditions, trucks often travel on dusty roads and replace high-quality oil filters in time. The impurities and contaminated particles in the oil are filtered through the filter. In this way, the oil entering the oil passage is very clean and can effectively prevent the abrasive wear caused by the particulate matter on the engine parts. After the filter has been used for a certain period of time, a lot of dirt will adhere to the filter element, so the filter should be replaced regularly.

It is necessary to replace the oil and oil filter of the car in time, and it is necessary to replace the quality oil filter every time. When the filter is used for a long time, its filtration efficiency will decrease, and the oil pressure passing through the filter will be greatly reduced.
Although the oil pressure is reduced to a certain extent, the filter bypass valve will open, and the oil will enter the oil passage through the bypass to prevent the oil pressure from being insufficient. However, the oil entering the oil passage is not filtered, and will carry impurities into the oil passage. Increase the wear of the machine. In severe cases, the impurities in the oil may even block the oil passage, causing mechanical failure. Therefore, the quality of the oil filter directly affects the effect of the oil on the engine lubrication.
