An energy conservation cycle engine which can eliminate NOx and unburnt matter, reduces environmental pollution, reduces also a friction loss and vibration of a cycle engine, raises a maximum combustion pressure, reduces CO2, reduces the thickness of a main combustion chamber and its weight, reduces a specific weight per output and increases a specific output per weight. A piston has a stepped shape in which a small diameter portion protrudes from a large diameter portion having a cup-like recess, and a cylinder head has a shape for accepting, and fitting to, the piston so as to dispose two combustion chambers. Further, a tapered reduced diameter portion functioning as a fan-shaped nozzle is added so that a combustion gas can efficiently move from the main combustion chamber to a sub-combustion chamber. <IMAGE> <IMAGE> |
