摘要：
In the top face of a piston (6), there is formed a cavity (30) having a bottom surface (32) which slopes downward toward an exhaust side and which includes a raised part (32a) extending from near the center of the bottom surface to an intake-side wall surface. The cavity guides fuel spray (15) which has been injected by an injector (12) and passed by an electrode part (14a) of a spark plug (14), to arrive near the electrode part of the spark plug again in the form of an air-fuel mixture (15a).
