Appl. No.:

12/873930

International Classification:

F02B 13/00
F02B 75/32

US Classification:

Abstract:

An internal combustion engine comprises a rotating connector engaged rotatably in the rotatable receptacle. The rotating connector includes two rotational axles, two radial arms extending from the rotational axles, and an off-center middle axle connected to the two radial arms, and the two rotational axles share a common axis and are parallel to the off-center middle axle. The upper end is rotatably connected to the off-center middle axle of the rotating connector and the lower end is rotatably connected to the crankshaft. The internal combustion engine goes through an engine cycle comprising an intake phase, a compression phase, a expansion phase, and a exhaust phase. During the intake and compression phases the piston travels between a top dead center and a first bottom dead center. During the compression and exhaust phases the piston travels between a second bottom dead center to the top dead center.

Abstract:

An internal combustion cyclone engine includes a gas hole, a gas hole plugging protrusion, and oblique holes. The gas hole is provided in the piston, and connects the explosion chamber with the combustion chamber. The gas hole plugging protrusion is provided in the cylinder and configured to be inserted into and seal the gas hole while the piston is pushed up. Oblique holes are provided around the gas hole through the top plate portion of the piston, and each of the oblique holes connects the explosion chamber with the combustion chamber concentrically and obliquely. At the top dead center the top plate portion of the piston almost touches the top wall portion of the cylinder. At the start of the expansion phase before ignition substantially all of the compressed gas is in the explosion chamber and whirls around inside the explosion chamber during the compression phase.
