空气滤清器的任务是滤除进入气缸的空气中的悬浮颗粒物,以减少气缸与活塞、活塞环的磨损。发动机工作所需的3种介质中,空气用量最大,而且来自大气。如果空气滤清器不能有效地滤除空气中的悬浮颗粒物,轻者加速气缸、活塞及活塞环的磨损,重则造成气缸拉伤,缩短发动机的使用寿命。 Air filter’s mission is to filter out the air into the cylinder of suspended particles to reduce the cylinder and piston, piston ring wear and tear. Of the three media required for engine work, the largest amount of air is used and it comes from the atmosphere. If the air filter can not effectively filter the suspended particles in the air, the lighter accelerates the wear of the cylinder, the piston and the piston ring, the more it will cause the cylinder strain and shorten the service life of the engine.
