Engine fuel injection control apparatus

摘要

An engine fuel injection control apparatus includes a variable valve device (100) that at least varies an intake valve open timing of an intake valve (23). A controller (70) adjusts the variable valve device (100) and a fuel injection timing of a fuel injection valve (53). The controller (70) controls a fuel injection end timing in accordance with an overlap amount of the intake valve (23) and an exhaust valve (33). The controller (70) adjusts 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 until and the intake valve open timing is set to become increasingly larger, upon determining that the engine (1) is being cold started and the overlap amount is larger than the prescribed overlap amount.
