特徴とするスパークアシスト筒内噴射エンジン。 Fuel is directly injected into a cylinder from a fuel injection valve having a plurality of nozzle holes, at least a portion of the injected fuel is attached to the wall surface of a combustion chamber and evaporated, and the fuel evaporation is promoted using an intake swirl. In a spark-assisted direct injection engine that transports evaporated fuel to the ignition plug and ignites it at the ignition plug for combustion, fuel injected from multiple nozzle holes in a direction opposite to the swirl direction adheres to the engine. A spark-assisted in-cylinder injection engine is characterized in that a recess is provided only in the wall surface of the combustion chamber to generate a swirl flow and a squish flow in the forward direction.
