′In a direct injection engine that has a cavity combustion chamber at the top of the piston that is offset from the center of the piston, and in which fuel is injected into this cavity combustion chamber from a fuel injection nozzle, the side wall of the cavity combustion chamber is approximately parallel to the axial direction of the piston. At the same time, the bottom surface of the cavity combustion chamber is inclined with respect to the axial direction of the piston, so that the depth of the bottom surface on the piston center side is made larger than the other part of the bottom surface, and the fuel injection nozzle is injected from the fuel injection nozzle. A combustion chamber for a direct injection internal combustion engine, characterized in that the center of gravity of the fuel spray is shifted closer to the center of the piston than the center of the cavity fuel chamber.
