What is the function of an air filter?
The air filter is arranged in front of the carburetor or air inlet pipe to play the role of filtering dust and sand in the air to ensure adequate and clean air in the air cylinder.
Between larger particles into the piston and the cylinder, will cause serious scuffing, which is particularly serious in dry sandy environment
The engine will swallow a lot of air in the working process, if the air is filtered, suspended in the air dust to be sucked into the cylinder, piston and cylinder will accelerate the wear
