This paper describes an internal combustion engine. It comprises: a housing having an intake port at one end thereof and an exhaust port at the other end thereof; a compression chamber in the housing near the one end; compressor means in the compression chamber; a compressor transfer port opening through the downstream outlet wall; an expansion chamber in the housing near the other end thereof to receive combusted gases; work means in the expansion chamber driven by expanding, combusted gases; means rotating the compressor outlet wall at the same rotational drive speed as the expander inlet wall; an expansion chamber inlet port opening extending through the upstream inlet wall; a cylindrical combustion chamber block rotatable in the housing intermediate the compression chamber and the expansion chamber; at least two combustion chambers in the block; means rotating the block at a reduced speed relative to the speed of rotation of the compressor outlet wall and the expander inlet wall; means for igniting the charge of compressed gas during the intermediate portion of each revolution of the combustion chamber block. The combustion chambers being substantially hemispherical; the speed of rotation of the compressor outlet wall is in the same ratio to the speed of rotation of the combustion chamber block as the number of combustion chambers in the block is to the number of combustion chambers less one.
