Abstract: A fuel injection apparatus for an engine includes a fuel pump, a common rail, a fuel injection valve, and a pressure detector. The pressure detector detects pressure of fuel as actual fuel pressure. The apparatus compares the actual fuel pressure with target fuel pressure determined based on an operational state of the engine. The apparatus computes at least one of a lift amount, by which a nozzle needle of the valve is displaced from a valve seat of the valve, and a lifting speed, at which the nozzle needle is displaced from the valve seat, to be smaller with an increase of a difference between the target and actual fuel pressures when the actual fuel pressure is greater than the target fuel pressure. The apparatus applies the drive pulse to the drive unit based on the at least one of the lift amount and the lifting speed.
