1. Change the oil. Engine oil is equivalent to the lubricating oil of the engine, lubricating, cleaning, cooling, sealing, reducing engine wear. It is of great significance to reduce the wear of engine parts and prolong the service life. Regular oil changes can increase the life of refrigerated trucks.

2. Replace the oil filter element. Oil contains a certain amount of gum, impurities, moisture and additives. In the working process of the refrigerated truck engine, the metal chips generated by the friction of various components, impurities in the inhaled air, oil oxides, etc., are the objects of oil filter. If the oil goes directly into the oil cycle without filtering, it will negatively affect the performance and life of the engine. Therefore, it is necessary to replace the oil filter element regularly.

3. Replace the air filter element. The engine of a refrigerated truck absorbs a lot of air during its operation. If the air is not filtered, dust will accelerate the wear of the piston group and cylinder. Large particles entering between the piston and the cylinder can also cause the cylinder to pull. The role of the filter element is to filter dust and particles in the air to ensure that enough clean air enters the cylinder.

4. Replace the gasoline filter element. The gasoline filter can provide clean fuel for the refrigerator engine and filter out moisture and impurities in the gasoline. Thus, the performance of the engine is optimized while providing the best protection for the engine. In short, do a good job of the overhaul of the refrigerated truck. Regular replacement of oil and gasoline equipment can ensure the service life of the refrigerated truck and ensure its efficiency.
