A rotary internal combustion engine comprising a cylinder bore in a stator sealed between parallel end walls; a power shaft concentric with the cylinder bore journaled in bearings in the end walls; an annular eccentric piston fixed onto the engine shaft just clearing the end walls and the cylinder as it rotates. A first abutment with one end pivotally anchored in the stator near 10:00 o'clock, the other end projecting clockwise and free to swing vertically in the cylinder space, seals the space between the cylinder and the piston from end wall to end wall, forming the counter-clockwise end of a combustion-expansion chamber. A second abutment, pivotally anchored in the stator near 2:00 o'clock, its free end projecting counter-clockwise and sealing the space between the cylinder and piston from end wall to end wall, forms the clockwise end of the combustion-expansion chamber. Both abutments are spring biased downward toward the piston. The combustion chamber, centered near 12:00 o'clock, comprises a shallow arcuate cavity adjacent the path of the piston, opening into and combining with the cylinder space. Fuel injection means for the invention engine is mounted preferably in the engine head. An air intake port is positioned in the vicinity of 3:00 o'clock to admit air into a compression chamber formed ahead of the rotating eccentric piston, the air pressure to lift the free end of the first abutment to allow the piston head to sweep a charge of air into the combustion chamber. Exhaust means comprises preferably at least one poppet valve per cylinder positioned in the engine head.
