ABSTRACT:
A fuel injection control apparatus for an internal combustion engine includes a fuel injection portion that performs each of first fuel injection for performing stratified-charge combustion, and second fuel injection for performing homogeneous-charge combustion; and an injection distribution ratio control portion that controls an injection distribution ratio. The injection distribution ratio control portion controls the injection distribution ratio to a target injection distribution ratio set based on a predetermined engine condition after start of the engine. An initial injection distribution ratio is set based on an engine condition at a time of start of the engine, and a change in the injection distribution ratio is controlled by referring to the engine condition after the start of the engine, when the injection distribution ratio is changed from the initial injection distribution ratio to the target injection distribution ratio.
