  • Cylinder-injection type internal combustion engine and a fuel injection control apparatus therefor
    Patent number: 5722363
    Abstract: A fuel injection control apparatus for a cylinder-injection type internal combustion engine performs a switching of fuel injection control modes in accordance with the operating state of the internal combustion engine when the engine is operating in a steady state. When the internal combustion engine is operating in a transitional state, for example, when the engine is accelerating or decelerating, a fuel injection control mode suited for the transitional operating state is selected preferentially over the mode selection for a steady state by a fuel injection control mode switching means. Consequently, the fuel injection control apparatus permits desirable operation of the internal combustion engine, making it possible to greatly improve the drivability of a vehicle in which the engine is installed.
