Semi-trailers usually encounter the following problems during driving:

1. Frequent starting and stopping, causing rapid wear of the engine; Driving in the city, it is inevitable to encounter traffic jams, stopping and starting 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 and 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, gasoline is not burned fully, which is easy to produce a large amount of carbon deposits, accelerate the oxidation of lubricating oil, cause the lubricating oil to fail, and lose its due lubrication protection performance.

2. Fuel is also the key to 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-grade 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 detonation will also destroy the lubricating oil film on the cylinder wall and deteriorate the lubrication of the parts. The test shows that a certain engine works for 200 hours with and without detonation. It is determined that the average wear of the upper part of the cylinder with detonation is more than twice that without detonation. In addition, fuel with excessive impurities will also accelerate the wear and corrosion of parts.

Before traveling, the semi-trailer should do a safety inspection. However, it is inevitable to encounter emergencies during driving. If you drive to a place where there is no village in front and no shop behind, it will be troublesome if there is a problem. If you master some common problems and emergency treatment methods, you will solve a lot of problems, at least you can solve the urgent problem. The following is a compilation of some common problems and emergency solutions for card friends.

1. Broken oil pipe. If the oil pipe of the semi-trailer is broken during driving, you can find a rubber pipe or plastic pipe that is suitable for the diameter of the oil pipe, temporarily connect it, and then tie the two ends with wire.

2. Oil leakage from the oil pipe joint. You can wrap cotton gauze around the lower edge of the horn, and then tighten the oil pipe nut and the oil pipe joint; you can apply bubble gum to the position of the oil pipe nut seat to seal it.

3. The trailer leaks oil and water. According to the size of the sand hole, you can choose an electrician's fuse of the corresponding specification and gently smash it into the sand hole to eliminate oil and water leakage.

4. When the motor vehicle is in use, if the oil tank is leaking and the oil tank is damaged, you can wipe the leaking area clean and apply bubble gum to the leaking area to temporarily block it.

5. The inlet and outlet hoses are broken. If the rupture is small, you can wrap the rupture with soap on the cloth; if the rupture is large, you can cut off the rupture of the hose, put a bamboo tube or iron tube in the middle, and tie it with wire.

6. The valve spring is broken. You can remove the broken spring, install the two broken sections in reverse, and then you can use it. If the spring is broken into several sections, remove the intake and exhaust valve adjustment screws of the cylinder and close the valve.

7. The fan belt is broken. You can use wire to connect the broken belts in series, or drive the car away after a while.
