This paper investigates on the improvement of gerotor type engine oil pump noise. Gerotor type pump is widely used as oil pump because of its simplicity and high efficiency. Noise from gerotor oil pump is basically affected from teeth number of its inner rotor and oil passage system. By increasing teeth number and improving relief valve and oil passage system, harmonic order noise was definitely decreased.
