3. INTRODUCTION
The Cyclone engine is a high efficiency, compact, and
powerful external combustion engine that can run on
traditional fuels or bio fuels.
 Created by Cyclone Power Technologies, it is also
called a "Schoell Cycle" engine after inventor Henry
Schoell. Incorporating a process of heat regeneration, it
is touted as a 21st century update to the traditional
Rankine cycle steam engine.
The Cyclone Engine is capable of running on
virtually any fuel (or combination of fuels)
including today’s promising new bio fuels, while
emitting far fewer pollutants than traditional gas
or diesel powered internal combustion engines.

4. How It Works
 The Cyclone Engine is a Rankine Cycle heat
regenerative external combustion engine, otherwise
known as a “Schoell Cycle” engine.
 It creates mechanical energy by heating and cooling
water in a closed-loop, piston-based engine system.

5. Functional Description`
The Cyclone Engine is built of three major components,
the Steam Generator, Piston Block, and Condenser. The
working fluid, deionized water, travels continuously through
these three components. Beginning in the steam generator
moving into the pistons, then to the condenser, and finally
pumped back into the steam generator.

6. Rankine cycle
 The Rankine cycle is a model that is used to predict the performance
of steam turbine systems. The Rankine cycle is an idealized
thermodynamic cycle of a heat engine that converts heat into
mechanical work. The heat is supplied externally to a closed loop,
which usually uses water as the working fluid.

9.  HEAT PROCESS
1. Fuel is atomized and injected into the patented centrifugal combustion chamber
(shown as lifted off the engine block for better viewing), where a spark ignites the
fuel-air mixture into a flame that spins around the heat coils. Thermocouples (not
pictured) control the duration of combustion to keep the heat in the combustion
chamber at a constant temperature.
 2. Water contained in the coils becomes super-heated steam (up to 1200°F) in as
little as 5 seconds from start up which is (a) piped to the cylinders, (b) where it
enters through a patent-pending valve system (not pictured). Note, valve timing
mechanisms regulate how much steam enters the cylinders – the longer the cut-
the greater the torque and acceleration.
 MECHANICAL PROCESS
3. Steam enters the six radial-configured cylinders under pressures up to 3200 psi
push the pistons down in sequence. Note, no motor oil is used – water is both the
working fluid and engine lubricant. Also, because of the valve design, the engine
starts without the need of a starter motor.
 4. The rotating action of the pistons connected through a patent-pending spider
bearing (not pictured) turns the crank shaft. Note, because the greatest amount of
torque occurs at the first rotation, the shaft can be directly connected to a drive
train without a transmission.

10.  COOLING PROCESS
5. Steam escapes the cylinders through exhaust ports and (a) enters the
pending condensing unit where it turns back into water, and (b) collects in a
sealed pan at the bottom of the condenser. Note, this is a closed-loop system
the water does not need to be replaced or topped-off.
 6. Blowers spin fresh air around the condenser to speed the cooling process.
 REGENERATIVE PROCESS
7. (a) Air which has been pre-heated from the condensing unit, (b) continues
to a second heat exchanger located in the exhaust port of the combustion
chamber, further pre-heating the air used for combustion while also cooling
exhaust fumes (to about 320°F).
 8. A high pressure pump (not pictured) pipes water from the collecting pan to
the heat coils (a) via heat exchangers surrounding each of the cylinders (only
one pictured), and then (b) to the center of the coils to start the heat cycle
again.

OPERATION

12. Heat regenerative engine(CE)
 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.

15. Why It's Better
 All-fuel : A traditional gas or diesel powered internal combustion
engine ignites fuel under high pressure inside its cylinders – a explosive
process that requires precise fuel to air ratios.
Because of the way we burn fuel – in an external combustion chamber
under atmospheric pressure -- we have incredible flexibility as to the
fuel we use. In combustion tests we have used fuels derived from
orange peels, palm oil, cottonseed oil, algae, used motor oil and fryer
grease, as well as traditional fossil fuels … none of which required any
modification to our engine. We have also burned propane, butane,
natural gas and even powdered coal.
 Earth-friendly: Several aspects of the Cyclone make it more eco-
friendly than internal combustion engines.

16. Fuel Choice: The Cyclone Engine can run on 100% bio fuels (i.e., it does
not require a 15% or less mixture with fossil fuels), and these new sources
can provide true carbon-neutral alternatives to fossil fuels.
Longer Burn Time: The Cyclone Engine’s patented cyclonic combustion
chamber allows for a longer burn time, which means that more carbon
particles are incinerated before being exhausted.
Lower Burn Temps: The Cyclone Engine burns its fuel at low
temperatures (about 2200°F), which is below the temperature at which
most harmful NOx gases are created.
Cooler Exhaust: Exhausted gases run through a heat exchanger before
leaving the engine, lowering the temperature at release to about 350
degrees … hundreds of degrees lower than internal combustion exhaust.
No Motor Oil: Water (de-ionized) is the Cyclone Engine’s sole lubricating
fluid, which means there is no waste oil to change, dispose or leak into
ground.
Quieter Run: Internal combustion engines have an explosion that emits
supersonic sound waves out the exhaust valves to the atmosphere,
requiring a muffler system. The Cyclone’s exhaust is virtually noise-free.

17. Lower Cost
• The Cyclone Engine is a one-piece unit that travels
without an “entourage” of complicated components.
Eliminating these subsystems reduces cost, size and
weight, while increasing overall efficiency and reliability
of the engine. For instance, the Cyclone Engine needs:
• No catalytic converter or muffler
• No oil pump or motor oil
• No transmission or transmission fluid
• Overall, the Cyclone Engine has fewer parts to
manufacture, assemble and, ultimately, break-down or
wear-out.

18. High Efficiencies
The Cyclone Engine is a highly efficient external combustion engine, with
efficiencies nearing the top diesel engines on the market today. Higher
efficiency means less fuel required to produce the same work.

19. ADVANTAGES(BIO FUELS)
• Clean burning – Provides complete combustion and a very clean exhaust
• Efficiencies comparable to diesel
• Low noise, vibration, and infrared signatures
• Provides an ideal power source for hybrid and conventional vehicles.
• Large range of sizes possible – from 1 KW up to over 1 Megawatt.
• Facilitates conversion to a range of synthetic fuels, including biomass.
• Does not require a radiator, water pump, oil pump, complex fuel injection, or
catalytic converter, reducing cost, weight, space and increasing reliability.

20. Applications
 The Cyclone engine has the potential to be used in many applications from small appliances and
lawnmowers to large marine propulsion plants and power plants. One major intention of the Cyclone
Engine is for use in automobiles. As of April, 2011, the engine is being developed for use in several
