ABSTRACT:
A rotary combustion engine comprising a housing having an inner trochoidal surface and a rotor mounted within the housing and having apex portions having sealing cooperation with said trochoidal surface to form a plurality of working chambers therebetween and in which said trochoidal surface is modified at least in the region at the ends of its minor axis by displacing said surface outwardly in this region to avoid the usual crest in each of these regions and further in which the rotor periphery is modified so that it is substantially the inner envelope of this modified trochoidal surface.
