ABSTRACT:
In a direct fuel injection type spark ignition internal combustion engine, fuel is assisted in evaporation by a squish flow. The engine includes a squish portion for generating the squish flow, a spark plug located adjacent to a center of a cylinder, and a fuel injector. The squish portion is enlarged so as to closely oppose the spark plug at the opening end of the squish portion. The fuel injector is located at a closed end of the squish portion and injects at least one portion of the fuel onto either one of two squish portion defining surfaces defining the squish portion therebetween. Evaporation of the fuel injected onto and adhering to the squish portion defining surface is promoted by the squish flow before being ignited by the spark plug.
