噴射式火花点火機関。 In direct injection spark ignition engines, in which fuel is injected from the fuel injection valve toward the top of the piston, and the evaporated fuel is ignited and combusted by the spark plug, the fuel injected from the fuel injection valve at the top of the piston under light load. An in-cylinder injection spark ignition engine is characterized in that a groove is formed at the position where the spark ignition hits to reflect hot fuel toward the spark plug.
