特徴とする内燃機関の電子制御燃料噴射装置。 A fuel injection amount setting means for setting the fuel injection amount based on the engine operating state, an engine acceleration state detection means for detecting the acceleration operating state of the engine, an engine load detection means for detecting the engine load, and an increase in the fuel injection amount. a correction coefficient storage means that stores correction coefficients for increasing the correction amount in accordance with the engine load; and a correction coefficient storage means that stores a correction coefficient corresponding to the engine load, and a corresponding correction coefficient from the correction coefficient storage means based on the engine load detected by the engine load detection means. a correction coefficient search means for searching for a coefficient; and a fuel injection amount setting means based on the correction coefficient searched by the correction coefficient search means when the acceleration operating state of the engine is detected by the engine acceleration state detection means. The fuel injection valve includes an increase correction means for increasing the set fuel injection amount to set the fuel injection amount, and a fuel injection valve drive control means for driving and controlling the fuel injection valve based on the set fuel injection amount, an engine deceleration state detection means for detecting a deceleration state of the engine; and an opening drive of the fuel injector by the fuel injection valve drive control means when the engine deceleration state detection means detects that the engine is in a predetermined deceleration state. In an electronically controlled fuel injection device for an internal combustion engine, the electronically controlled fuel injection device for an internal combustion engine is provided with a fuel injection stop means for stopping control, when deceleration other than a predetermined deceleration operation state in which the fuel injection valve opening drive control is stopped by the fuel injection stop means. When the engine load is equal to or less than a predetermined load in an accelerated operating state immediately after the operating state, the fuel injection amount is adjusted by the increase correction means based on a predetermined limit correction coefficient that is smaller than the correction coefficient corresponding to the predetermined load. An electronically controlled fuel injection device for an internal combustion engine, characterized in that an increase correction regulating means for performing an increase correction is provided.
