Abstract
The intake flow velocity near the jet of a fuel injection valve is obtained on the basis of the engine rotational speed, engine intake air quantity and intake valve opening area. A crank angle position for maximum intake flow velocity is set as the timing for completion of fuel injection by the fuel injection valve. As a result, fuel injection can be reliably completed at a timing giving good fuel atomization characteristics.
