ンジンの燃料制御装置。 An operating state detection means for detecting the operating state of the engine in an engine in which one fuel injection injector is provided in the upstream part of the intake passage, and the injector supplies fuel to each cylinder;
a fuel injection amount setting means for setting a fuel injection amount by the injector based on the output of the operating state detection means; an acceleration determination means for determining an acceleration state of the engine; and a deceleration determination means for determining a deceleration state of the engine; Acceleration increase correction means receives the output of the acceleration determination means and corrects the set value of the fuel injection amount by the fuel injection amount setting means to the increase side in a predetermined acceleration state; deceleration reduction correction means for correcting the set value of the fuel injection amount by the fuel injection amount setting means to a reduction side in the state, and the acceleration increase when the fuel reduction by the deceleration reduction correction means exceeds a predetermined value. 1. A fuel control device for an engine, comprising a fuel increase reset means for resetting the fuel increase value by the correction means.
