Title:
REDUCED NOISE SOLENOID CONTROLLED FUEL PUMP
Document Type and Number:
WIPO Patent Application WO2006060545
Kind Code:
A9
Abstract:
A high pressure fuel pump with reduced audible and hydraulic noise. The fuel pump incorporates a control scheme that utilizes an electronically controlled on/off type solenoid actuated valve (26, 33) to control pump fuel delivery and/or fuel system rail pressure. The power pulse for energizing or de-energizing the solenoid is selectively modified to slow the force verses time profile acting on the solenoid valve during the on/off and off/on transition.
