ABSTRACT:
An internal combustion engine comprises a hollow rotary engine body, an axially opposite pair of main pistons capable of rotating with but slidably reciprocating relative to the engine body, a cam mechanism for causing the main pistons to make one full rotation with the engine body as the piston makes two reciprocations, and a pair of axially fixed auxiliary pistons coaxially inserted into the respective main pistons. A main combustion chamber is formed in the engine body between the main pistons, whereas a pair of auxiliary combustion chambers are formed in the respective auxiliary pistons. Explosive combustion takes place alternately in the main combustion chamber and each auxiliary combustion chamber.
