ABSTRACT:
In one embodiment of the invention, the engine comprises a rotary-piston, Wankel-type machine having a ceramic-material housing. Within the wall of the housing are confined pluralities of passageways which provide conduits for the conduct therethrough of coolant, for the introduction of a primary or secondary fuel, and for the ignition of the wall-confined-passageway-supplied fuel. The coolant passageways open only externally of the housing, whereby the same supply and discharge coolant to dissipate engine heat. The fuel passageways have openings, which open onto the inner wall of the housing, for supplying air/gasoline-vapor mixture, or methane, or hydrogen, or diesel oil, etc. The ignition passageways confine electrical leads, which leads have a spark-gap interruption formed in each thereof, and also have openings which open onto the inner wall of the housing -- the interruptions being disposed in registry with the openings. Further, the openings in the fuel passageways and the ignition passageways are in immediate adjacency -- to effect controlled combustion. With reference to the direction of piston travel, pairs of fuel and ignition openings are spaced apart along the inner surface of the housing wall so that a cascade-effect combustion can be generated.
