Abstract
A fuel supply apparatus for an internal combustion engine having a plurality of cylinders, which supplies fuel through fuel injection valves provided corresponding to the plurality of cylinders. An amount of fuel supplied to the engine is controlled by changing a fuel injection period of said fuel injection valve, and performing a fuel injection with a plurality of injection modes including a reference injection mode. A fuel injection amount parameter for controlling a valve opening period of the fuel injection valve in the reference injection mode, is calculated according to an operating condition of said engine. When the injection mode is determined to be another injection mode which differs from the reference injection mode, the fuel injection amount parameter is corrected so as to compensate shortage or oversupply of the fuel injection amount according to a correction parameter indicative of a time period which affects a pressure change of the fuel supplied to the fuel injection valve caused by employing the other injection mode.
