An electronically-controlled cylinder fuel supply system in which an injector and an ignition plug are provided for each of combustion chambers, in which on the basis of an instruction signal to an engine and a speed of revolution of the engine, the fuel injection initiation timing and valve open duration of the injector, the ignition timing of the ignition plug and the quantity of suction air are determined through retrieval of values from a map stored in a ROM, in which a throttle valve is controlled such that the suction air quantity measured by an air flow meter coincides with the suction air quantity determined by the map retrieval, and in which the injector is provided with a fuel holding portion for temporarily holding the fuel injected during the lowered pressure of the combustion chamber and a vibration element for vibrating the fuel holding portion to atomize the fuel to thereby scatter the atomized fuel into the combustion chamber.

An electronically-controlled cylinder fuel supply system for an engine comprising: a plurality of combustion chambers each of which is provided with a fuel injector and an ignition plug; a suction air path for supplying air into each of said combustion chambers; an exhaust path for discharging an exhaust gas from each of said combustion chambers; sensor means for sensing an operating condition of said engine; first means for determining the amount of fuel to be injected and the time of ignition for discharge of said ignition plug for each combustion chamber on the basis of sensed signals from said sensor means; means for causing said fuel injector of each combustion chamber to inject said amount of fuel determined by said first means directly into the associated combustion chamber within the period of time from initiation of the intake stroke of the combustion chamber to the time of said ignition as determined by said first means for the respective combustion chamber; and second means for determining an air quantity to be drawn into said suction air path on the basis of said sensed signals from said sensor means; wherein said injector comprises a fuel holding portion provided at a fuel injection end of said injector for temporarily holding injected fuel therein and a vibration means for vibrating said fuel holding portion such that the fuel held in said fuel holding portion is atomized and scattered in said combustion chamber in the atomized state.
