クアシスト式アルコールエンジン。 A spark-assist alcohol engine that is configured to spray fuel from an injection nozzle into high-pressure gas in a combustion chamber pressurized during the compression process, and ignite a portion of the fuel spray using a spark plug to enter the combustion process. , a heat-resistant cap is attached to the end of the spark plug opposite the combustion chamber,
An ignition chamber that accommodates the electrode of the spark plug is formed within the heat-resistant cap, and is located downstream of and opposite to the fuel spray inlet that guides a portion of the fuel spray into the ignition chamber and the swirl in the combustion chamber. A spark-assisted alcohol engine characterized by having a flame outlet.
