気筒内燃機関の電子制御燃料噴射装置。[Claims for Utility Model Registration] (1) A fuel injection valve that injects a predetermined amount of fuel into an intake passage upstream of an intake throttle valve at predetermined intervals in synchronization with engine rotation based on a control signal from an injection amount control means; an idle control valve that controls the intake flow rate of an auxiliary air passage that bypasses the intake throttle valve by a control signal of an idle control means, and the air-fuel mixture introduced through the intake passage and the auxiliary air passage is passed through the intake manifold. In an electronically controlled fuel injection system for a multi-cylinder internal combustion engine, the intake throttle valve opening detection means detects the opening degree of the intake throttle valve, and the idle control valve detects the opening degree of the idle control valve. A control valve opening detection means, a water temperature detection means for detecting engine cooling water temperature, and a control valve opening detection means for detecting a cooling water temperature of a specific cylinder based on at least one of the detected intake throttle valve opening, idle control valve opening, and cooling water temperature. An electronically controlled fuel injection device for a multi-cylinder internal combustion engine, comprising: a correction means for decreasing or increasing an injection amount at an injection timing substantially corresponding to an intake stroke compared to the predetermined injection amount for other cylinders. (2) The correction means reduces the injection amount corresponding to the intake stroke of a specific cylinder to zero, and stops the fuel injection corresponding to the intake stroke of the specific cylinder. An electronically controlled fuel injection device for a multi-cylinder internal combustion engine according to item 1.
