The engine must inhale a large amount of air during operation. If the air is not filtered, dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious "Cylinder Scoring" phenomenon, which is particularly serious in dry and sandy working environments.

The air filter element is a kind of filter, also called air filter cartridge, air filter, ventilation device, etc. Mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms.

The air filter installed in front of the carburetor or intake pipe to filter out dust and sand in the air to ensure that sufficient, clean air enters the cylinder.

The function of the crankshaft bearings is to bear the rotational gravity, tension, centrifugal force, etc. transmitted to the crankshaft by the connecting rod. It plays the role of lubricating and fixing the guide crankshaft.
