ABSTRACT:
An ignition system for rotary piston engine wherein a glow plug mounted in the epitrochoidal housing of the engine is supplied with electric power to maintain the surface temperature of the glow plug within a range from 900.degree. to 1100.degree. C. A control unit for controlling the supply of electric power to the glow plug produces an output pulse signal the pulse width thereof being varied depending on engine operating conditions such as the amount of fuel supply and engine rotational speeds. A power circuit receives the pulse signal from the control unit and on-off controls the supply of electric power to the plug from a battery.
