20090084345 | Reciprocating Rotation Type Engine and Power Transferring Device and Hybrid System Using the Same - A reciprocating rotary engine of the present invention includes a torus-shaped chamber which is divided into two regions. Each divided region forms a sealed chamber. Also, each sealed chamber is divided by a piston attached to a shaft whereby four sealed chambers are formed.

Each combination device has three rotational axes named by A, B and C, as in the case of a planetary gear unit or a differential gear unit. Following this notation, the torques of two axes, A and B are combined together and transferred to the remaining axis C. The two electric motors modulate the torque of B axis periodically in accordance with reciprocating rotary motion of the engine, to thereby provide a counterforce to oscillating power and transfer unidirectional torque to a drive shaft. Namely, the power from the engine can be more effectively converted. Also, a hybrid system of the present invention includes a reciprocating rotary engine, and a power converter for converting reciprocating rotary motion into unidirectional revolutionary motion.

20100000492 | MODIFIED REVOLVING PISTON INTERNAL COMBUSTION ENGINE - In a revolving piston device the revolving assemblies are made to complete one or more revolutions for every revolution of the elliptical gears. Port operating ring is used to open the intake passage for the travel of piston pair from TDC to BDC in one revolution of the elliptical gears and to open exhaust passage for the travel of piston pair from BDC to TDC during the next revolution of the elliptical gears. Lower speed of the revolving components induces less vibrations thus gives quite operation. Lower speeds of the elliptical gears allow higher speed of operation for revolving piston device. These types of engines can be used in automobiles, aero industries, marine ships, battlefield tanks, power generation and many other applications. The same concept can also be used to develop a revolving piston compressor or a revolving piston steam engine or a revolving piston two stroke internal combustion engine. | 01-07-2010 |

20110030652 | Inertial Rotation Internal Combustion Engine - This invention called the IRICE uses rotational pistons (cystons). The IRICE is more efficient than a conventional piston engine by negating loses caused by reversal of the pistons in the engine bore. The IRICE contains two or more adjacent cystons with at least one head per cyston separating chambers contained in the housing between adjacent cyston heads. Cystons alternate their motions via a fluid or gas, called the pf, under pressure in relation to the pressure in adjacent chambers. The cyston(s) currently in motion, called the MOP cyston(s), contacts part of the IRICE, called the pushcan, producing torque. The cyston(s) static in relation to MOP(s) are called the SIP cyston(s). SIP's contacts a section of the IRICE called the clampcan that restricts it's motion allowing pf pressure in the chamber between the two aforementioned cyston's heads to exhort force moving the MOP cyston(s) and the pushcan to do work. Pf is moved through the IRICE chambers via inlets and outlets. | 02-10-2011 |

20090255507 | Piston Valve Internal Combustion Engine - An internal combustion engine of two perpendicular, toroidal cylinders intersecting at two junctions with each cylinder containing one piston filling half of its volume. The pistons are 180 degrees out of phase; each alternately occluding one intersection or the other. Each piston completes a full power, exhaust, intake, and compression stroke in one revolution. Endplates of 45 degrees allow the combustion chamber junction to be permanently filled and sealed at all times; first by one piston, then by the tips of both pistons as the complementary-angled endplates tangentially slide past one another, and then by the other piston. Compressed gases are shunted into the crossing cylinder's combustion chamber. Both pistons orbit continuously, one-way. Airflow is also one-way. Each piston is mounted to a sealed, 360-degree, counterbalanced ring gear. One ring gear is positioned centrally and the other peripherally to prevent interference. These maintain coordination between the pistons and provide output. | 10-15-2009 |

The elliptical gears also modulate the relative rotational speeds of these rotary pistons to thereby complete compression, power, exhaust and intake strokes four times in one revolution of a power output shaft of the engine. The rotary modulation engine with the above arrangements has smaller volume and improved efficiency as compared to the conventional four-stroke engine that requires two revolutions of the engine's crankshaft to complete four strokes. The rotary modulation engine can be applied to cars, ships, power generators and the like, and has reduced number of parts, volume and manufacturing cost while provides effectively upgraded operation efficiency. | 04-05-2012 |
