ABSTRACT:
An internal combustion engine includes a rigid wall having a curved surface which forms part of the combustion chamber. The remaining part of the combustion chamber is formed by a flexible curtain whose outer edge is attached and sealed to the rigid wall. The wall and the curtain together form a closed space whose geometry and volume depend on their relative position. When the curtain moves toward the wall, the two approaching surfaces displace gas toward the center of the combustion chamber, thereby compressing it or expelling it from the chamber.
