PROBLEM TO BE SOLVED: To provide an engine improved in heating efficiency. SOLUTION: In this multi-hybrid engine, a first piston mechanism 10 is structured to be operated by using the pressure of fuel gas, and a third piston mechanism 30 is structured to be operated by using the pressure of exhaust gas discharged from the first piston mechanism 10. Area of a third piston 350 structuring the third piston mechanism 30 is structured to be larger than area of a first piston 150 structuring the first piston mechanism 10. COPYRIGHT: (C)2006,JPO&NCIPI
