Supplies in major maintenance:
In addition to changing the oil and oil filter, there are the following two items in car maintenance:
1. Air filter
The engine has to suck in a lot of air during the working process. If the air is not filtered, the dust will accelerate the wear of the piston group and cylinder. Larger particles enter between the piston and the cylinder, but also cause serious "pull cylinder" phenomenon. The role of the air filter element is to filter the dust and particles in the air, to ensure that the cylinder enters enough and clean air.
2. Gasoline filter
The function of the gasoline filter element is to provide clean fuel for the engine and filter out the moisture and impurities of the gasoline. Thus, the engine performance is optimized and the best protection is provided for the engine.
Usually, in the maintenance of the car, the operator will do other checks according to the specific situation of the car, but also increase other maintenance items, such as the inspection and cleaning of the engine related system, the positioning inspection of the tire, the inspection of the fastening parts and so on.
