Recently, the need for noise reduction of high pressure fuel pump has been increasing due to rising environmental consciousness and improving comfort. Based on our acoustic investigation under idling condition, we identified that the solenoid noise and the compression noise are dominant on high pressure fuel pump. We have investigated the acoustic improvement technique of the solenoid noise for high pressure fuel pump and came to a conclusion that the solenoid noise can be reduced ca. 3dB by using optimization of control parameters and a reduced spring force. In this paper, we explain the concept of noise reduction, the control method and the extent of acoustic improvement.
