operation, and foreign body get into the engine air intake or the exhaust pipe, it will cause
the turbine and compressor blade damaged, and it can smash turbine shell in serious
condition. When using supercharged engine in desert area and area with bad working
environment, small dust can get into supercharger by damaged pipeline gap of air filter or
air intake system, which will lead to the wear of supercharger impeller air inlet. Therefore,
frequently check and maintain the air intake system pipeline and air filter, and timely
change filter element to reduce the happening of this fault.

(e). Check whether there is cracking in
