| 123045000 | ROTARY RECIPROCATING PISTON | 7 |
| 20090194071 | Sorrels engine - An internal combustion engine of uniquely simple elements that combines the use of an assemblage of rotating elements to restrain cylinders radically coplanar perpendicular to centerline of the power shaft and pistons and connecting rods to a rotating coplanar reciprocating alignment with the cylinders, channels to force strokes of the pistons and connecting rods, with the energy of the power stroke and the resistance of the same by the channels producing a force that rotates the assemblage inside a ported engine housing. Engine should be lighter, able to use a variety of fuels, able to use simplified ignition systems, produce more power and be more cost efficient to manufacture and operate than existing engines of the same displacement. Once engine position and fuel is decided elements of the fuel, cooling, lubrication, ignition and electrical systems can be included in the drawings. | 08-06-2009 |
| 20090199821 | METHOD TO CONVERT FREE-PISTON LINEAR MOTION TO ROTARY MOTION - Embodiments described herein include a method for converting free-piston linear motion to rotary motion, comprising:

| 20100101534 | MULTIPLE-FUEL ROTARY ENGINE - A multiple-fuel rotary engine includes a cylinder seat, a cylinder body, pistons, an intake/exhaust regulation module, a cover, and a top lid. The cylinder body has bores receives the pistons therein and when the cylinder body carries the pistons to rotate, making gas holes thereof positioned under an intake channel, the gas holes are first set in communication with a first sub-channel of the intake channel and then the second sub-channel, whereby two fuel supply systems respectively and sequentially supply two different fuels into the same bore to complete an intake stroke of two different air-fuel mixtures. Combustion of the air-fuel mixtures in the bore provides explosion energy that drives the piston outward to complete the operation of the engine. | 04-29-2010 |
| 20130098335 | X-ENGINE ASSEMBLY WITH PERFECT BALANCE - An X-Engine assembly includes four cylinder banks which are located on two intersecting planes with the crankshaft axis being on the line of the intersection of the two planes, and having a Double-Acting Scotch Yoke (DASY) power conversion system that couples the reciprocating motion of the pistons with the rotating crankshaft to provide pure sinusoidal piston motion. A series of DASY X-Engine configurations that satisfy even-firing for both 2-stroke and 4-stroke, and other engine cycles, achieve perfect balance with regard to vibrating forces and moments that are all zero, and all configurations have zero torsional vibration of the crankshaft resulting from the reciprocating masses. | 04-25-2013 |
| 20130276757 | ROTARY RECIPROCATING PISTON ENGINE - This internal combustion engine utilizes a rotary piston motion simultaneously having an upward and downward stroke to facilitate a power output. In comparison to existing engines, this engine possesses fewer parts, has enhanced fuel economy and performance, and is capable of using alternative fuels. The drive shaft is connected directly to the piston and a fixed arm is attached to the driveshaft. The fixed arm has a rotating bushing traversing upon an inclined bearing surface to allow rotary and reciprocating motion of the piston. | 10-24-2013 |
| 20080289606 | Piston Cam Engine - The invention relates to a piston cam engine used in different field of the mechanical engineering, as internal-combustion engines compressors, pumps etc. The cam engine comprises cylinders ( | 11-27-2008 |
| 20100108034 | Rotary Engine - A rotary engine ( | 05-06-2010 |
