    Abstract: A toroidal engine that can be powered by a fuel/air mixture or by a compressed gas source. The toroidal engine uses one-way bearings to transfer torque generated in a toroidal chamber directly to a drive shaft. Pairs of pistons are mounted on two crank assemblies, which are concentric with the drive shaft. One-way bearings allow the crank assemblies to turn, one at a time, in one direction only. The crank assemblies are directly coupled to the drive shaft, which eliminates the need for complex gear and linkage arrangements. A system can be used with the toroidal engine to alternately stop the crank assemblies at a pre-determined position and to time the ignition of the engine.

The assembly includes parts without cooling channels that comprise a monolithic ceramic material or ceramic matrix composite material capable of allowing the engine when assembled to operate at elevated temperatures that would cause metal parts of a metal engine to lose strength, lose structural and mechanical integrity, suffer excessive oxidation/corrosion and/or fail. The ceramic material also allows the engine when assembled to operate with significantly lower heat loss to the surrounding environment as compared with a similar engine made using all metal parts. The ceramic material allows the engine when assembled to operate without requiring substantial cooling elements or an external fluid (e.g. water) cooling system. The engine when assembled as described will retain more heat or operate with a substantially reduced rate of heat rejection when compared to an entirely metal rotary engine.

    Abstract: Rotating bar within eccentric wheel was previously invented. But that was only suitable for pumps. In my proposed invention I used two dissimilar bars of same length named as prime mover and follower which are incorporated within eccentric wheel. The follower bar-end is hinged with prime mover bar-end while that prime mover bar-end is fixed at the centre of the circular housing named as power shaft. Prime mover rotates the eccentric wheel and that wheel rotates the follower the hinged joints and this assembly rotation creates differential volume repetitively and spark in compression stage creates combustion. This principle of engine operation also includes different sealing types and outward opening type cam assembly. In conventional reciprocating engine lots of power is lost because of change of direction of piston motion. This problem can be overcome by my proposed engine design which will lead to higher efficiency in automobile.

  • Publication number: 20130228149
    Abstract: The present invention is a rotary internal combustion engine, comprising an outer stator shell which forms several equal-sized stator chambers and an oscillating axle which forms several pistons corresponding to the stator chambers and separating each stator chamber into two sealed combustion chambers. When operating, the combustions of the combustion chambers cause the oscillating axle to oscillate. The oscillating motion is then translated to a mono-directional rotary motion, which provides the power output.

  • Publication number: 20130228150
    Abstract: A rotary engine has a rotor that has rockers pivoting in chambers. As each rocker pivots, it rotates an outer crankshaft. Each outer crankshaft has a spur gear that engages a stationary ring gear. Spur gear rotation causes the gears and the outer crankshafts to revolve around the ring gear. This cause the rotor to rotate. As the rotor rotates, successive chambers are positioned at the intake, compression, ignition, and exhaust positions. Igniting the fuel in the ignition position pushes the rocker inward to rotate the outer crankshaft associated with that rocker to cause the rotor to rotate.

  • Publication number: 20130133613
    Abstract: An internal combustion engine having combustion chambers that rotate about a main shaft axis in a step-wise manner. A first and second rotors each have elongate pistons that are interdigitated so that when one rotor rotates with respect to the other rotor, some chambers between the interdigitated pistons are reduced in volume and other chambers are increased in volume. Respective one-way bearings connect the first and second rotors to the main shaft to incrementally rotate it. Fuel mixture and exhaust apparatus is connected to one end of the engine to feed a fuel mixture to the increasing-volume chambers and extract the exhaust from other decreasing-volume chambers. At the same time, yet other chambers are experiencing compression and ignition cycles. An oil pump is driven by the first and second rotors for circulating a lubricant from a reservoir, through the engine parts to be lubricated and then back to the reservoir to cool the lubricant.

  • Publication number: 20130118445
    Abstract: The rotary piston engine 10 has a stationary central core 12 having a primary axis and radially offset inlet and combustion sections, the cylinder rows and their pistons rotating about the offset inlet and combustion sections, and the outer housing 18 rotating concentrically about the primary axis of the core 12. The cylinder rows are linked to the outer housing 18 to provide a 1:1 rotational correspondence, despite the different rotational axes of the cylinder rows and outer housing 18. The pistons are connected to the concentrically rotating outer housing 18 by connecting rods, thus moving inwardly and outwardly in their cylinders as their cylinder rows rotate about the radially offset inlet and combustion sections of the core 12. The engine 10 is devoid of complex valve mechanisms due to the rotary valve effect provided by the rotation of the cylinder rows around the stationary core 12.

  • Patent number: 8418672
    Abstract: An internal combustion engine having a generally rotary design is described. The engine includes a rotor that alternately rotates about first, second, and third axes of rotation as the rotor circulates within the engine. Each axis of rotation is about perpendicular to the other two axes of rotation. The rotor includes two flanges that alternately compress fluid in combustion chambers as the flanges rotatably enter and sweep through compression lobes. Detonation of compressed, combustible fluid occurs in the combustion chambers, force from the detonation driving the rotor about the axes of rotation. The rotor exerts maximum leverage on a power shaft at the point of detonation, and continues to exert similar leverage on the power shaft as the rotor rotates. The engine typically includes one or more power modules, each of the one or more power modules having three compression lobes and three combustion chambers.
