Fuel Common Rail Injector Auto Parts Diesel Injector 321-3600 for CAT Auto

As a diesel engine is used over time, some parts may wear out or become damaged. Therefore, regular replacement of these parts is key to maintaining engine performance. The following are some common parts that need to be replaced:

1.Engine oil and oil filter: The engine oil lubricates the internal engine components and prevents wear. The oil filter is responsible for filtering out impurities in the engine oil. It is recommended to replace the engine oil and oil filter regularly according to the manufacturer's recommendations and vehicle usage. Generally speaking, the engine oil and oil filter need to be replaced every 5,000 to 10,000 kilometers. If the vehicle is often driven under harsh conditions, these parts may need to be replaced more frequently.

2.Fuel coarse filter and fine filter: The fuel coarse filter can filter out large particles of impurities in the fuel, while the fine filter can further filter out fine particles in the fuel. Both filters need to be replaced regularly to keep the fuel system working properly. It is recommended to replace the fuel coarse filter and fine filter regularly according to the manufacturer's recommendations and vehicle usage. Generally speaking, the primary and secondary fuel filters need to be replaced every 5,000 to 10,000 kilometers.

3.Air filter: The air filter prevents impurities in the air from entering the engine and protects the engine from damage. It is recommended to replace the air filter regularly according to the manufacturer's recommendations and the vehicle's usage. Generally speaking, the air filter needs to be replaced every 1,500 to 2,500 kilometers. If the vehicle is frequently driven in areas with poor air quality, the air filter may need to be replaced more frequently.

4.Spark plug: The spark plug is responsible for generating sparks in the combustion chamber to ignite the mixture. As the use time increases, the spark plug may wear or become damaged, resulting in reduced engine performance. It is recommended to replace the spark plug regularly according to the manufacturer's recommendations and the vehicle's usage. Generally speaking, the spark plug needs to be replaced every 2,000 to 3,000 kilometers. If the vehicle is frequently driven in high or low temperature environments, the spark plug may need to be replaced more frequently.
