  • Accumulator type fuel injection control system and the method thereof
    Patent number: 5906188
    Abstract: In an accumulator type fuel injection control system, a fuel pressure setting means determines a basic fuel injection pressure from both fuel injection volume and engine speed, and when the temperature of a fuel discharged to a fuel tank is high, a fuel pressure correcting means subtracts, from the basic fuel injection pressure, a pressure reduction quantity which has been set according to the fuel temperature. Further, a fuel injection timing correcting means adds, to a basic fuel injection timing, an advance quantity which has been set according to the pressure reduction quantity and thereby determines a corrected fuel injection timing.
