Abstract
In a direct injection internal combustion engine which switches a fuel injection mode between a batch injection in which fuel is injected once and a split injection in which fuel is injected at a plurality of timings, a fuel increase amount is set larger for the split injection than for the batch injection when increase-correcting a fuel injection quantity set based on an engine operating state.
