Just bought the Yuchai 4D 130 run 3000 kilometers, air pump with a click click. The engine speed is high, the sound also follows big, after the gas hits is normal
You this is a normal phenomenon, Yuchai 4108 pump part with protection valve, engine driven air compressor gas will also have pressure relief, the inflation is completed before the opening and closing of the valve to protect both the formation of the click frequency increased with the pump shaft speed increased, the pump shaft speed it is with the engine speed is proportional to the. After the charging is finished, the protection valve is normally open, neither clicks. I say a few words for use, focusing on the car maintenance and driving, air filter, oil filter if you don't change it, could cause premature wear of pump and other components of the engine, if the pump bearing clearance is large, there will be noise, but this is not your!
A normal phenomenon, there ` s no such Yuchai machine is what problems you run is ` I promise
