  • Fuel injection system for internal combustion engine
    Patent number: 6722345
    Abstract: A fuel injection system carries out a multi-injection. A preceding injection affects a pressure in a combustion chamber at a succeeding injection. In order to ensure an amount and timing of a succeeding injection, the ECU carries out a compensating process. In one embodiment, an injection period for the succeeding injection is corrected by varying a corrective value in accordance with parameters indicative of a pressure deviation. In another embodiment, each of the injection amounts for preceding and succeeding injections is corrected in accordance with deviations from a standard pressure respectively. The deviation is determined based on an intake pressure.
