るアルコールエンジン。 In an alcohol engine in which alcohol fuel is injected into a cylinder and combusted, a throttle valve is provided in the intake system, and a spark plug is installed in the cylinder, and the alcohol fuel is sprayed by natural ignition at a high compression ratio. burn it,
Moreover, the alcohol engine is characterized in that the intake air is throttled by the throttle valve to lower the compression ratio at the time of startup and at low temperatures, and the spark plug ignites and burns the spray of the alcohol fuel.
