ABSTRACT:
A fuel injection control apparatus for an internal combustion engine includes a basic injection quantity calculation unit for calculating a basic injection quantity on the basis of an intake air quantity and an engine speed. A deposit detection unit detects a deposit quantity indicating a quantity of deposit deposited in an air intake system of the internal combustion engine, the deposit containing carbon particles. A correction unit calculates a real injection quantity using the basic injection quantity and the deposit quantity when the internal combustion engine is operating in a steady state within a predetermined period after the internal combustion engine is started.
