  • Non-synchronous injection acceleration control for a multicylinder internal combustion engine
    Patent number: 4573443
    Abstract: An apparatus for controlling fuel injection in a multicylinder internal combustion engine, wherein fuel injectors for each cylinder are simultaneously operated synchronous with crank angles. The amount of injection is controlled by signals from an air flow meter. The apparatus includes a system operating, nonsynchronous with crank angles, the injectors when the engine is accelerated. The amount of nonsynchronous fuel injection is controlled in accordance with the position of the nonsynchronous injection (i.e., occurrence of acceleration) between adjacent synchronous injections.
