Abstract
A system and method for controlling fuel pressure in a fuel delivery system. The system includes a fuel pump and an inlet control valve. The inlet control valve is operated to a closed state by an electrical signal applied to the inlet control valve. The electrical signal includes a pull-in portion of the electrical signal that is applied to the inlet control valve having a pull-in time interval that is varied based on the fuel pressure. By varying the pull-in time interval to control fuel pressure, electrical energy consumed and acoustic noise generated by the fuel delivery system are reduced.
