Abstract
A method for controlling a mechanical solenoid valve of a high-pressure fuel pump to supply fuel to an engine is provided. In one example, current supplied to the mechanical solenoid valve is adjusted according to a pressure downstream of the fuel pump. The method can reduce current used to operate the mechanical solenoid valve as well as pump noise, at least during some conditions.
