A fuel injection valve that directly injects a fuel into a combustion chamber from a rim of a cylinder toward a center line of the cylinder in a slanting direction toward a lower portion of the combustion chamber, an ignition plug that is arranged at substantially a center of the cylinder, and injection openings from which a spray that forms a shape that widens toward an end from a portion near a center of the combustion chamber toward a side wall of the combustion chamber on a cross-section perpendicular to a direction of injection is injected are included.
