Oil filter

As an oil filter, it is also what we often call a machine filter. It is generally replaced with the oil during maintenance. Its main function is mainly to filter out impurities in the oil, so as to be used for lubrication, cooling and cleaning inside the engine. Then it is inevitable that a thing will produce many stains after a long time, especially when it reaches its due life. Not only can it not be cleaned, it will also cause pollution, which is why the oil filter will be replaced by the way every time the oil is changed.For Japanese cars, they are generally replaced every 5,000 kilometers, while German cars and American cars are generally replaced every 10,000 kilometers.

Air filter

As an air filter, it is easy to confuse with another product, the air conditioner filter, but it is also well distinguished. The air filter is mainly to filter out impurities in the air that enters the engine and reacts with the fuel for combustion, so as to protect the cylinder, piston and other parts from damage. It is generally installed at the air inlet of the engine. The maintenance cycle generally ranges from 10,000 kilometers to 30,000 kilometers, mainly based on different models to judge.

Air conditioner filter

For air-conditioning filters, it is mainly to filter the air from the outside world into the car in the car's air-conditioning system, so that the impurities, dust, pollen, tiny particles, etc. in the air are isolated. In contrast, one is to filter the air in the car and the other is to filter the engine gas. It seems similar, but in fact it is very different. It is generally a grid-shaped box body, which is also often called an air-conditioning grid. The general replacement cycle is 10,000 kilometers to 30,000 kilometers, and most models are replaced once every 20,000 kilometers.

Gasoline filter

Gasoline filters are important auto parts that filter fuel impurities, provide clean fuel for the engine, and protect the engine and oil supply system.In the process of production, storage and transportation of gasoline, it is inevitable that certain impurities such as iron oxide, dust, etc. will be produced, or the oil quality of some stations is poor in itself and contains a lot of impurities. If these impurities are not filtered out and brought into the engine and oil supply system, it may damage the cylinder or cause blockage of the fuel injector. The general replacement cycle is 30,000 kilometers to 60,000 kilometers, and some models are even longer.
