摘要： A fuel injection system for an internal combustion engine having the normal crankshaft and plurality of cylinders each with an intake passage and an exhaust passage. An intake stroke detector is provided for detecting if a particular cylinder of the engine is experiencing an intake stroke. Responsive to an intake stroke being detected, a fuel injector is actuated to inject fuel into the intake passage of the particular cylinder during its intake stroke. The engine is equipped with an exhaust gas recirculation system for recirculating a part of exhaust gases from the exhaust passage to the intake passage of each cylinder. A fuel injection timing control mechanism is provided for advancing the fuel injection timing responsive to operation of the exhaust gas recirculation system to control the fuel injection period relative to the intake stroke.
