To provide an incylinder direct injection engine with improved fuel economy as well as improved output.

This in-cylinder direct injection engine is provided with a first injector 13 facing a combustion chamber 12 and a second injector 14 facing a intake port 4. Gasoline is injected from the first injector 13, while high octane fuel (light oil fuel) is injected from the second injector 14. Furthermore, this in-cylinder direction injection engine is controlled such that, in operation ranges except for medium to low engine speed and high load, gasoline is injected only from the first injector 13.
