ABSTRACT:
The invention is an internal combustion engine for two or four cycle mechanical power generation. The engine has an annular cavity formed between its rotor and casing and around the rotor rotational axis. The rotor surface at the annular cavity has undulation(s) and the casing surface at the annular cavity has a plurality of circumferentially spaced axial plane slots each with a partition pivotally extending into the annular cavity but not abutting the annular cavity walls and in the combustion region therein and when there is a compression region to very close proximity of the cavity walls. The partitions in the annular cavity form a plurality of circumferential spaced volume varying chambers which cyclically vary in volume with rotor rotation. The partitions are displaced in their slots by a rotor cam means outside the annular cavity with undulations allowing the continued extension of the partitions to the rotor undulant surface in the annular cavity without abutting it. The power out loss due to the allowed mass flow between neighboring volume varying chambers is sustained rather then the large losses that occur if volume varying chambers where closed to one another in the annular cavity and the wear of the parts in the annular cavity. The engine has intake means, exhaust means, and fuel injection means arranged at the annular cavity allowing the volume varying chambers to function in a four cycle or two cycle mechanical power generation process. Ignition means if used in the engine, are used only once per operation to initiate combustion in the annular cavity, thereafter the combustion process in the annular cavity is self perpetuating.
