The Cyclone engine is a low temperature, low pressure, self starting engine. The engine can run using heat from fuel combustion, exhaust heat from engines, and on fuels such as bio fuels and solar energy. As the cyclone engine is a regenerative engine, it uses de-ionized water as both working fluid and lubricant.
Similar to a heat exchangers, water is circulated though pipes around a chamber, which either has an exhaust from an engine or burns fuel inside it. The preheat water then enters a steam generator wherein more heat is added to it to convert it into super heated steam. The air is heated and forced in the combustion chamber to increase the combustion process. An igniter ignites the fuel mixture in the chamber. The speed of the engine is controlled using a cam arrangement. The steam expands due to high temperature and pushes the piston down in a piston arrangement, which rotates a crank and crankshaft. The used steam exhausts to a condenser wherein it is converted to water. The water from the condenser is again send around the heat exchanger and thus the cycle repeats itself.
The advantage of the cyclone engine is that the fuel burns for a much longer period inside the combustion chamber, resulting in slow and efficient combustion and extremely low amount of heat loss to the environment. This engine can burn any type of fuel, including powdered coal, and does not need any external lubrication.
