In a direct injection diesel engine comprising a nozzle, the cavity is arranged such that the center of the cavity is located closer to the center of the cylinder hole than the tip of the nozzle and closer to the end of the cylinder hole than the center of the opening. Further, the fuel injection nozzle is mounted so that the axis of each injection hole intersects the inner wall surface of the cavity at the same angle in a substantially horizontal plane at the maximum road dead center position of the piston. direct injection diesel engine.
