The Cyclone Engine is designed around the principles of an external combustion engine, to efficiently use any liquid or gaseous fuel and create more power and significantly less emissions than current gasoline or diesel powered internal combustion engines.
Schoell cycle engine is a cross between a Rankine, Diesel and Carnot cycle engine. Compact, scalable technology, expects to have a production prototype in around eight months, as of March, 2007. Applications will range from weed eaters to trains. It could also use concentrated solar as the input heat source.
The Cyclone answers the problems of size, complexity, and high pressure gasses that have kept the Stirling engine from becoming practical.

Stage of Development
Quoting from http://cyclonepower.com/about.htm
Cyclone Technologies has completed its initial research and design of the engine, and has already successfully bench-tested single and twin cylinder engines in the smaller power range.
Four six-cylinder engines are currently being assembled. Bench testing on these medium scale engines will commence within the next few months.
We are well beyond the proof of concept stage.

The Schoell cycle is an external combustion engine.
Its highest torque is at 1 rpm.
A 100 HP Cyclone engine would weight about 320 pounds, but would not require a radiator, transmission, catalytic converter, nor complex electronic ignition controls, reducing all those expenses, on top of being more inexpensive to build than the 400-lb ICE equivalent.
It only has one cam and six valves. It doesn't require exhaust valves. It uses composite bearings.
The expanding/contracting fluid is deionized water, which is maintained in a closed system. The engine is water lubricated, not requiring replenishment of the lubrication. There is no blow-by of lubricant.
The engine harnesses the heat from fuel combustion in a heat exchanger system. The fuel burns for a much longer period of time, allowing for a more complete burn, and very little of the emitted heat is lost to the environment, but is converted to rotational torque. Internally, the temperatures don't go above 2000 degrees. The external temperature is about 350 Fahrenheit, which could be put to use in a Combined Heat-Power (CHP) application.
The noise level of the engine is much lower than in an ICE. You can hear the combustor as a lull sound; you can hear the blower, which sounds like the fan on an ICE. There is no exhaust noise.
The Cyclone can burn any liquid or gaseous fuel, and has even run on powdered coal. It would eliminate the need for expensive refinement of petrol, and requires no additives for lubrication. The engine would still require a fuel filter to keep the gunk out, but its orifices are much larger than diesel or fuel injection engines.
The company thinks the Cyclone engine will have greater longevity than the traditional I.C.E.
- U.S. Patent No. 7,080,512 (PDF) - Heat regenerative engine; Harry Schoell; Cyclone Technologies LLLP; July 25, 2006
- A heat regenerative engine uses water as both the working fluid and the lubricant. In operation, water is pumped from a collection pan and through a coil around a cylinder exhaust port, causing the water to be preheated by steam exhausted from the cylinder. The preheated water then enters a steam generator and is heated by a combustion chamber to produce high pressure super heated steam. Air is preheated in a heat exchanger and is then mixed with fuel from a fuel atomizer. An igniter burns the atomized fuel as the flames and heat are directed in a centrifuge within the combustion chamber. The speed and torque of the engine are controlled by a rocker and cam arrangement which opens a needle-type valve to inject high pressure super heated steam into a cylinder having a reciprocating piston therein. The injected steam expands in an explosive action on the top of the piston at high pressure forcing the piston down and drivingly rotating a linked crank cam and crankshaft. Exhaust steam is directed through a centrifugal condenser having an arrangement of flat plates. Cooling air from blowers circulates through the flat plates to condense the steam to a liquid state. The water condensation is returned to the collection pan for subsequent use in steam generation.

Quoting from http://cyclonepower.com/about.htm
The engine is scalable in its size and output such that it can be utilized for applications ranging from small generators, household, and lawn equipment, to medium scales addressing automotive, power boats, and light trucks, and the larger scales required in the trucking, commercial marine, off road construction equipment, and stationary generator markets.
"In addition to developing the engines, the Cyclone team has secured an initial tier of investment, participated in major engineering trade shows, signed a contract with an investment group for the manufacturing rights of this engine in marine applications, and made marketing contacts with generator manufacturers, automobile manufacturers, and diesel engine builders." About
The company does not plan on manufacturing, but will be licensing the technology for its myriad of applications. Detroit has shown quite a bit of interest.
Presently they are considering a public offering. They need about $5 million US.
