Use of air filter:
1, the role of the air filter is to filter 98% ~ 99% of the dirt in the air to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat;
2, some engine air filters are also installed with resonators, resonators are conducive to reducing suction noise. The purpose of replacing the air filter element; The air filter is located at the entrance of the inlet, and the dust, moisture and oil in the air are filtered by the air filter element during the driving of the car;
3, when the paper filter element adsorbs too much dirt will be blocked, the air intake will decrease, the engine power will decrease, at this time should replace the air filter element; The air filter of the car is usually replaced every 15000km (or 1 year).
The role of the air filter: the engine in the working process to suck in a lot of air, if the air is not filtered, the dust suspended in the air is sucked into the cylinder, it will accelerate the piston group and the wear of the cylinder. Larger particles entering between the piston and the cylinder will cause a serious "cylinder pulling" phenomenon, which is particularly serious in a dry and sandy working environment. The air filter is installed in the front of the carburetor or the intake pipe to filter the dust and sand in the air to ensure that sufficient and clean air is entered into the cylinder.
Air filter is a device that is mainly responsible for removing particulate impurities from the air. When the piston machinery (internal combustion engine, reciprocating compressor, etc.) works, if the air contains impurities such as dust, it will aggravate the wear of the parts, so it must be equipped with an air filter. The air filter is composed of two parts: a filter element and a housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and can be used continuously for a long time without maintenance.
