|The Cyclone Engine is a Rankine Cycle heat regenerative external combustion, otherwise known as a “Schoell Cycle” engine. In short, the Cyclone is a 21st century, high efficiency, compact and powerful 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. To date, Cyclone has over 1,000 hours of running and testing our engines, has achieved verified thermal efficiencies above 30%, and is very close to putting the first of these engine models into small-scale commercial production.
From waste energy and solar thermal power generators to cars, trucks, trains and ships, we see a day when our planet will be powered in a sustainable manner by just One Engine – the Cyclone Engine.
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-off the greater the torque and acceleration.
3. Steam enters the six radial-configured cylinders under pressures up to 3200 psi to 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.
5. Steam escapes the cylinders through exhaust ports and (a) enters the patent-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.
7. (a) Air which has been pre-heated from the condensing unit, (b) continues up 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 the exhaust fumes (to about 320°F).
