PURPOSE:To make the constitution simple and to make the cost low, by computing the amount of fuel injection based on the pressure in a fuel container, determining the opening time of a discharge valve based on the computation, and delaying the operating signal of the discharge valve later than the starting time of the fuel injection. CONSTITUTION:A fuel injection valve 2 injects the fuel into a fuel volume chamber 1. An electromagnetic valve 7 discharges the fuel in the fuel volume chamber 1. The pressure in the fuel volume chamber 1 is detected by a pressure pickup 6. The detected signal is inputted to a control device 8 through an amplifier 11. The control device 8 computes the amount of fuel injection from the fuel injection valve 2, determines the opening time of the electromagnetic valve 7 based on the result of computation, delays the operating signal of the electromagnetic valve 7 later than the starting time of the fuel injection of the fuel injection valve 2 by a specified time, and outputs the result. |
