Title: Ignition device for rotary piston engine

Abstract: An ignition device for a rotary piston engine includes a glow plug which is mounted at an ignition port formed in an engine housing to communicate with a combustion and operation chamber and which, when electrically powered, is heated to red hot to ignite an air-fuel mixture in the combustion and operation chamber. The glow plug ignites the air-fuel mixture through a communicating port which is formed to face the combustion and operation chamber and which has a smaller aperture area than the cross-section area of the ignition port.
