ABSTRACT:
A pressure storage (common rail) fuel injection system for an engine is provided, in which the fuel injection pressure rise response when quickly accelerating the engine is improved, engine output shortage is prevented, engine noise is reduced, and improvement is made with respect to soot generation and exhaust gas particulation. A booster is provided to boost pressurized fuel fed out from a pressure storage with a directional control valve for piston operation. Low pressure fuel injection in which fuel from the pressure storage is fed directly to fuel injection valve for injection, and high pressure fuel injection in which fuel having been boosted by the booster is fed to the fuel injection valve for injection, are switched one over to the other by a directional control valve for fuel injection control.
