<p>An internal combustion engine comprises a housing (4) having a peripheral wall with a cylindrical internal surface and side walls defining a chamber. A rotor (18) is disposed within the chamber and has at least one recess (20) in its periphery. At least one pivotally mounted piston (22) is disposed in each of the recesses and has a pivotal end and a movable end defining collapsible chambers above and below the piston. A cam track (42) is carried on the inside of at least one of the side walls and followers (44, 46) operably interconnect the cam track and the movable end of the piston. An ambient air intake port (63) opens into the peripheral wall of the housing. An exhaust port (61) and at least one combustion chamber (54) are disposed in the peripheral wall of the housing. A fuel injector (52) is in communication with the combustion chamber and compressed air transfer ducts, valves and passageways are disposed at least in part exteriorly of the engine side walls, establishing fluid communication between the chamber below the piston and the chamber above the piston.</p> |
