るスパークアシスト式メタノールエンジン。 In a spark-assisted methanol engine, fuel is radially injected from each nozzle at the tip of a multi-nozzle injection nozzle inserted into the cylinder head into a combustion chamber on the top surface of the piston, and ignited and combusted by an ignition means. The tip of the multi-hole injection nozzle is offset from the center of the combustion chamber to be close to the side wall surface of the combustion chamber, and the reach area of the injected fuel is short from the multi-hole injection nozzle to the side wall surface of the combustion chamber. A spark-assist methanol engine characterized in that a flat part is formed to reflect the fuel injected from the multi-hole injection nozzle toward the opposite fuel injection direction.
