Abstract

A distribution type fuel injection apparatus has a fuel injection pump having a solenoid valve for controlling pressure of a high-pressure chamber of the apparatus. The solenoid valve is actuated or deactuated at the optimum time for fuel injection end or beginning by a control signal produced by a circuit for computing the optimum timing in accordance with the condition of engine operation. Thus, precise control of injection timing or injection amount injected can be attained by electronic control without a complex mechanical structure.
