The engine of any large truck and semi-trailer vehicle is the dominant one among all the parts. So how should the driver maintain the engine of the semi-trailer in normal times? The following are some common problems and solutions for you, hoping to be helpful to the driver.
Usually, semi-trailers will encounter the following problems during driving:
- Frequent starting and stopping, causing rapid wear of the engine;
Driving in the city, it is inevitable to encounter traffic jams, stop-and-go is common, and it is inevitable to speed up and slow down, merge and rush. Generally speaking, new cars will gradually experience insufficient power, reduced control sensitivity, and increased noise after driving in the city for about 2-3 years. These phenomena are related to the frequent start-stop of the car, which causes engine wear. Therefore, minor repairs are often carried out, which costs a lot of money and time. However, few people know that when the car starts and stops frequently, the gasoline is not burned fully, which is easy to produce a large amount of carbon deposits, accelerate the oxidation of the lubricant, cause the lubricant to fail, and lose its proper lubrication protection performance.
2. fuel is also the key factor affecting the life of the engine;
The selection of fuel must comply with the brand specified by the vehicle. It is forbidden to use low-brand fuel, otherwise the engine will produce knocking when working, causing strong impact on the parts and increasing the additional load on the parts, thereby accelerating the wear of the parts. The high temperature, high pressure and shock wave generated by the knocking will also destroy the lubricating oil film on the cylinder wall and deteriorate the lubrication of the parts. The test shows that when an engine works for 200 hours with and without knocking, the average wear of the upper part of the cylinder with knocking is more than twice that without knocking. In addition, fuel containing excessive impurities will also accelerate the wear and corrosion of the parts.
