An Experimental Study on Identification of Noise Generation Mechanism And Its Improvement in Gerotor Oil Pump

Whine noise in engine oil pump system was issued in developing an engine. Generally, A noise of engine oil pump largely are classified two cases. The first one is a gearing noise caused by relative motion of inner rotor and outer rotor. The other is fluid pulsation noise caused by oil pressure fluctuation. The aim of the paper is to identify a noise mechanism in engine oil pump and improve its Noise. Also, it suggests to the guide line on the design of oil pump.
