PURPOSE:To control the injection amount on starting to a proper value by controlling fuel injection amount on the basis of the top dead center signal when a revolution-angle signal is not detected, in the method for controlling the fuel injection amount on the basis of the revolution-angle signal of a plunger. CONSTITUTION:Opposed to a signal rotor 60 fixed at the top edge part of the driving shaft 2 of a vane-type feed pump 4, a pick-up 62 is installed onto a roller ring 3, and the fuel injection amount is controlled by allowing a solenoid valve 44 to communicate or to be cut-off on the basis of the revolution-angle signal detected from the pick-up 62. In association with the position of the top dead center of a specific cylinder, a pulley 84 having a projection 84A and a sensor 86 which generates a top dead center signal, accompanied with the passing, are installed, and when the revolution-angle signal is not detected on cranking, fuel injection amount is controlled by the top dead center signal. Thus, the proper injection amount can be obtained on starting. |
