What are the types of engine filters?

The engine has air, oil, fuel three filters, air conditioning filters are generally called "four filters" in the car. They are respectively responsible for the engine intake system, lubrication system, combustion system cooling system medium filtration.

A. The oil filter is located in the engine lubrication system. Its upstream is the oil pump, the downstream is the engine in need of lubrication parts. Its role is to filter out harmful impurities in the oil from the oil pan, so as to supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs with clean oil, to play the role of lubrication, cooling and cleaning, so as to extend the life of these parts.

B. The fuel filter can be divided into carburetor and electric injection. For gasoline engines with carburetors, the fuel filter is located at the inlet side of the oil pump with low working pressure and generally adopts nylon shell. The fuel filter of electric injection engines is located at the outlet side of the oil pump with high working pressure and usually adopts metal shell.

C, the automobile air filter is located in the engine intake system, it is composed of one or several clean air filter components assembly. Its main function is to filter out harmful impurities in the air that will enter the cylinder, in order to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat.

D. Automobile air conditioning filter is used to filter the air in the car compartment and the air circulation inside and outside the car. Remove the air in the car or into the car air dust, impurities, smoke odor, pollen, etc., to ensure the health of passengers and remove the smell in the car, at the same time,the air conditioner filter also has the function of making the windshield not easy to atomize.

Replacement Cycle

Customers are generally advised to replace it every 15,000km. The automobile air filter often works in the harsh environment of the vehicle should not exceed 10 thousand kilometers to replace once. (desert, construction site, etc.) The service life of the air filter is 30,000 kilometers for cars and 80,000 kilometers for commercial vehicles.
