PURPOSE:To make it possible to carry out fuel injection uniformly to all engine cylinders, by providing, in a fuel spill passage, a solenoid valve for compensating the amount of fuel injection for each cylinder. CONSTITUTION:ECU9 provides a deviation between an average rotational speed and a rotational speed of each cylinder, and gives a compensating value for the amount of fuel injection for each engine cylinder. The fuel injection amount for each engine cylinder is controlled by the opening time of a solenoid valve 8. That is, the timing of termination of fuel injection which means that high pressure fuel flows to the low pressure side through a fuel spill passage 7, is controlled. Thereby, fuel injection is carried out uniformly to all engine cylinders. |
