摘要： The operation of a fuel injector for an internal combustion engine is controlled, wherein the fuel injector has an on time that includes a pull-in time during which injector current increases to a pull-in current followed by a hold time during which the injector current is limited to a hold current that is less than the pull-in current. A control circuit receives a pressure signal from a pressure sensor that corresponds to a pressure of fuel supplied to the fuel injector for injection into the engine, correlates the pressure signal with fuel pressure, and decreases the pull-in time with increasing fuel pressure.
