The upper and the lower sides of the end cap are provided with a gas vent and an oil-returning opening. The gas vent upwards goes through an air channel and enters a PCV valve. The oil-returning opening downwards goes through an oil-returning pipe and is connected with the engine oil chamber of the crankcase. The structure of the camshaft is hollow with a rotary dissociation chamber formed in middle. The end of the rotary dissociation chamber facing one end of the end cap is an air outlet and the other end of the rotary dissociation chamber is an air inlet.
