Abstract
A fuel injection control apparatus and method for an internal combustion engine are provided for appropriately controlling the amounts of fuel supplied from an in-cylinder fuel injection valve and a port fuel injection valve to a cylinder in a simple control approach while satisfactorily reflecting a fuel transport behavior as a whole cylinder. An ECU calculates a required in-cylinder injection amount and a required port injection amount, calculates an in-cylinder injected fuel behavior parameter of a fuel from the in-cylinder fuel injection valve and a port injected fuel behavior parameter of the fuel from the port fuel injection valve, a net in-cylinder injection amount in accordance with the in-cylinder and port injected fuel behavior parameters based on the required in-cylinder injection amount, and a net port injection amount in accordance with the in-cylinder and port injected fuel behavior parameters based on the required port injection amount.
