Abstract
A fuel injection valve is shifted, with respect to the bore center of a cylinder, toward one end of an engine's output shaft. A top surface of a piston has inclined surfaces, and is raised by the inclined surfaces. A cavity is formed by hollowing out portions of the inclined surfaces, and faces the injection axis of the fuel injection valve. In a vertical cross section taken along the plane passing through a particular location in an intake other-side region of a combustion chamber and the location of the fuel injection valve, the distance from an injection tip of the fuel injection valve to the wall surface of the cavity at the particular location is longer than that from the injection tip to the wall surface at a diametrically opposed location to the particular location.
