Patent ID: 7881856

Claim:
An apparatus for controlling fuel injection for an engine, which is provided with a fuel injection valve, an inlet valve and a variable valve mechanism that is configured to vary an opening characteristic of the inlet valve, the apparatus comprising: a required air amount computing unit configured to compute a required air amount based on an accelerator opening; a control amount computing unit configured to compute a control amount of the variable valve mechanism based on the required air amount; an injection control unit configured to provide fuel injection from the fuel injection valve by dividing the fuel injection into a first injection and a second injection subsequent to the first injection; an air amount computing unit that computes an intake air amount based on the control amount of the variable valve mechanism; and an injection amount computing unit configured to compute the second injection amount based on a deviation between the intake air amount computed by the air amount computing unit in a first injection amount computing timing of the first injection and the intake air amount computed by the air amount computing unit in a second injection amount computing timing of the second injection.
