Rotary combustion engine having improved ignition means

摘要

The improved ignition means for a rotary combustion engine of the type, having a rotor which planetates within a multi-lobed housing cavity which is partly defined by an inner peripheral wall surface, comprises a spark plug having an axis which extends substantially normal to the peripheral wall surface and has means forming a spark-gap disposed in an ante-chamber adjacent the inner peripheral wall surface. An ignition channel of small size in relation to the size of the ante-chamber extends from the ante-chamber through the peripheral wall surface and is disposed in offset substantially parallel relationship with the longitudinal axis of the spark plug.
