ABSTRACT:
A fuel injection control apparatus and method for an internal combustion engine are provided for appropriately calculating fuel injection times for an in-cylinder fuel injection valve and a port fuel injection valve, thereby accurately controlling the amounts of fuel supplied to the internal combustion engine from the in-cylinder fuel injection valve and the port fuel injection valve, respectively. The fuel injection control apparatus calculates an in-cylinder fuel injection amount which should be injected by the in-cylinder fuel injection valve, and calculates an in-cylinder fuel injection time which is a valve opening time of the in-cylinder fuel injection valve in accordance with the calculated in-cylinder fuel injection amount and an acquired cylinder internal pressure. The fuel injection control apparatus further calculates a port fuel injection amount which should be injected by the port fuel injection valve, and calculates a port fuel injection time which is a valve opening time of the port fuel injection valve in accordance with the calculated port fuel injection amount and a detected pressure within an intake system.
