Abstract
A feel injection system for an engine controls a behavior of a nozzle needle for controlling a fuel injection timing and a fuel injection amount. The system controls a hydraulic pressure applied to the nozzle needle for displacing the nozzle needle between its fully opened position and its fully closed position. The system so controls the hydraulic pressure applied to the nozzle needle as to quickly displace the nozzle needle from the fully opened position to a given position which is located between the fully opened and closed positions, on the other hand, slowly displace the nozzle needle from the given position to the fully closed position so as to decrease an impact load applied to a valve seat for the nozzle needle when the nozzle needle is seated onto the valve seat.
