Abstract:
1. An engine fuel injection control apparatus comprising: an intake port; a fuel injection valve provided in the intake port; a variable valve device that at least varies an intake valve open timing of an intake valve provided downstream of the fuel injection valve; and a controller operatively connected to the variable valve device and the fuel injection valve to adjust the variable valve device and a fuel injection timing of the fuel injection valve, the controller controlling a fuel injection end timing in accordance with an overlap amount of the intake valve and an exhaust valve, and the controller adjusting the fuel injection timing such that the fuel injection end timing is more advanced than the intake valve open timing and such that as an amount by which the overlap amount exceeds a prescribed overlap amount becomes larger, a time interval between the fuel injection end timing and the intake valve open timing is set to become increasingly larger, upon determining that the engine is being cold started and the overlap amount is larger than the prescribed overlap amount.
