DIRECT-FUEL-INJECTION-TYPE SPARK-IGNITION INTERNAL COMBUSTION ENGINE |
摘要 |
A direct-fuel-injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed on the top surface of the piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relative small thickness. In the engine, the side wall of the cavity facing the fuel injection valve, for leading the fuel to the vicinity of the spark plug, has a horizontal sectional shape consisting of a part of an ellipse shape of which two foci are at a position of the injection hole of the fuel injection valve and a position near to the spark plug in plan view, and the side wall has a deflecting portion to deflect the fuel toward the inside of the cavity.
