摘要： A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a fuel injection valve and a cavity formed on the top surface of the piston. The cavity has a bottom wall, a spark plug side wall and a fuel injection valve side wall. The fuel injection valve injects fuel toward the bottom wall of the cavity in stratified charge combustion. The fuel mainly proceeds toward the spark plug side wall of the cavity along the bottom wall, is deflected by the spark plug side wall and is led to the vicinity of the spark plug. In the engine, the spark plug side wall of the cavity is provided with a deflecting portion inclined toward the inside of the cavity. A first part of the deflecting portion provided on both sides of the spark plug side wall functions to lead the fuel to the vicinity of the spark plug. A second part of the deflecting portion on the central portion of the spark plug side wall functions to lead the fuel to a region neighboring the side of the fuel injection valve from the vicinity of the spark plug.

摘要： A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a fuel injection valve and a cavity formed on the top surface of the piston. The cavity has a bottom wall, a spark plug side wall and a fuel injection valve side wall. The fuel injection valve injects fuel toward the bottom wall of the cavity in stratified charge combustion. The fuel mainly proceeds toward the spark plug side wall of the cavity along the bottom wall, is deflected by the spark plug side wall and is led to the vicinity of the spark plug. In the engine, at least at a position where the fuel comes into collision, the bottom wall of the cavity is so inclined as to be deeper on the side of the fuel injection valve side wall than on the side of the spark plug side wall. An extended plane of the central portion of the fuel injection valve side wall intersects the upper wall of the cylinder at an obtuse angle on the side of said spark plug.
