火ガスエンジン。[Claims for Utility Model Registration] (1) The cylinder head has an auxiliary chamber approximately in the center, and has a passageway through which auxiliary gas for ignition flows in from the upper part of the auxiliary chamber, and is ignited in the auxiliary chamber by a spark plug, resulting in main combustion. A spark-ignition gas engine that forms a torch into a room, characterized in that a narrow throat-shaped passage is provided in front of an ignition plug in a sub-chamber. (2) Spark ignition, which has an auxiliary chamber approximately in the center of the cylinder head, has a passage for auxiliary ignition gas to flow in from the upper part of the auxiliary chamber, and is further ignited in the auxiliary chamber by a spark plug, forming a torch into the main combustion chamber. A spark-ignition gas engine in which a shelf-shaped protrusion is provided in front of the auxiliary gas supply port for ignition in a direction perpendicular to the axis of the sub-chamber to form a rich air-fuel mixture near the spark plug.
