Apparatus and method for controlling fuel injection of direct injection gasoline internal combustion engine |
摘要 |
Discrimination is effected as to which of low-pressure and high-pressure conditions the pressure of fuel to be fed to a fuel injection valve is in. If in the low-pressure condition, the fuel injection pulse widths are corrected by assuming that the fuel pressure is a predetermined reference pressure, since the detection errors of a fuel pressure sensor are large. If in the high-pressure condition, the fuel injection pulse widths are corrected based on an actual fuel pressure detected by the fuel pressure sensor.
