Abstract
A method and apparatus for controlling an engine involves detecting a crank angle of an engine; detecting a rotation number of the engine based on the crank angle; detecting an injection timing by a fuel injection valve; determining an acceleration state; calculating a time period from injection to acceleration initiation based on the acceleration state and the injection timing; detecting a load of the engine; determining an injection correction value based on at least the acceleration initiation timing and the rotation number of the engine; determining a fuel injection pulse width based on the injection correction value, and controlling the fuel injection valve accordingly.
