Direct injection engine
 A direct injection engine in which an injector injects fuel toward a cavity formed in a top surface of a piston to produce a locally distributed mixture around a spark plug is constructed such that the direction of a fuel spray ejected from the injector is varied during a fuel injection period to properly spread the mixture and prevent its local overrichness. The direct injection engine is provided with means for generating a swirl, for example, so that the fuel spray from the injector is directed toward the spark plug when the pressure in a cylinder is low in a compression stroke, and the fuel spray is deflected by the swirl away from the direction of the spark plug as the pressure in a cylinder increases.
