ABSTRACT:
An apparatus for supplying fuel to an internal combustion engine is disclosed. The apparatus includes an injector that is selectively opened and closed and a pump for discharging the fuel to the injector from a fuel reservoir. The injector is open to inject the fuel to the engine when the engine is running and closed when the engine is idling. The amount of fuel to be injected is adjusted based on the operating state of the engine. A pressure sensor detects an actual pressure of the fuel to be supplied to the injector. A controller computes a target pressure of the fuel to be supplied to the injector. The controller determines a presumed change of engine speed based on the operating state of the engine and controls the pump based on the presumed change.
