Direct fuel injection engine

An engine control unit (13) ignites a second air-fuel mixture when the direct fuel injection engine is operating in a high-load stratified combustion region. The air-fuel mixture is formed after a majority of a fuel stream is guided toward the upper portion of combustion chamber (1) above a cavity (4) by the bottom surface (4c) of cavity after the fuel stream first hits the peripheral wall surface (4a) of cavity.
