Abstract
A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a fuel injector for injecting fuel as a spray in nearly the shape of a fan having a relative small thickness, a spark plug and a cavity formed on the top surface of a piston. The cavity has a long and narrow groove-like shape. The spray is injected by the fuel injector such that the spray is almost parallel with the center axis of the piston, and impinges in the cavity. The spark plug is arranged in the upper portion of the cylinder to face the cavity.
