<P>PROBLEM TO BE SOLVED: To provide a double piston cycle engine that is more efficient than a conventional combustion engine and capable of reducing harmful exhaust emissions. <P>SOLUTION: A dual piston cycle engine includes: a first cylinder 01 housing a first piston 03 therein; a second cylinder 02 housing a second piston 04 therein; an intake valve 10 coupled to the first cylinder for allowing a fuel mixture to enter the first cylinder; an exhaust valve 11 coupled to the second cylinder for allowing an exhaust gas to exit the second cylinder; and an interstage valve 12 that couples an internal chamber of the first cylinder to an internal chamber of the second cylinder and configured to minimize dead space between the first and second cylinders, wherein the first piston performs only intake and compression strokes and the second piston performs only combustion and exhaust strokes and the first and second cylinders are thermally isolated from one another. <P>COPYRIGHT: (C)2012,JPO&INPIT |
