Abstract:
A fuel injection control apparatus of an engine equipped with a variable valve timing mechanism that controls the valve timing of at least one of an intake valve and an exhaust valve, comprising:a valve timing detector that detects the valve timing controlled by said variable valve timing mechanism; and a fuel injection controller that inputs with a signal from said valve timing detector to detect a state in which the valve timing is switched by said valve timing mechanism, computes a valve overlap amount of the intake/exhaust valves when the valve timing is being switched, corrects a transient correction amount of fuel being supplied to the engine based on the computation value of said valve overlap amount, corrects and computes a fuel injection quantity by said corrected transient correction amount, and outputs a signal for said fuel injection quantity to a fuel injection valve.
