Abstract
Abstract An energy conservation cycle engine which protects environmental pollution by reducing NOx gases, unburned materials and increases the specific output power per weight by reducing friction-loss and vibration, by reducing the wall thickness of the main combustion chamber, and by raising the maximum combustion pressure thereby reducing CO 2 in the exhaust gas. A piston has a cup-like recess at its top and a small diameter piston protrudes therefrom. A cylinder head conforms with the shape of the piston to accept the protruded portion so as to form two combustion chambers, a main chamber and a sub-chamber, and the lower end of the sub-chamber is tapered to accelerate the movement of the combustion gas between the two chambers.
