低セタン価燃料エンジン。 A low cetane number fuel that injects fuel as a spray in multiple directions from a fuel injection nozzle installed in the cylinder head, assists in ignition of this spray via a spark plug, and changes the swirl ratio according to the rotation speed and load. In the engine, spark plugs B are arranged to be exposed to at least one of the sprays and are provided at a relatively close distance to the fuel injection nozzle; A spark plug A is provided at a position slightly shifted from plug B in the swirl direction of the fuel spray, and when the swirl ratio is high, the spark plug A is ignited, and when the swirl ratio is low, the spark plug B is ignited. A low cetane number fuel engine characterized by ignition.
