Cyclone Power Technologies Completes Gasoline Combustion Tests; Green Engine Produces Few Noxious Emissions

POMPANO BEACH, FL--(Marketwire - September 20, 2007) - Cyclone Power Technologies (PINKSHEETS: CYPW) announced today that it has successfully tested its Green Revolution Engine™ to verify the combustion temperatures of low octane gasoline. The design of Cyclone's fuel injector, which works with a primary and secondary air source, maintained a low temperature flame front (under 2300 degrees Fahrenheit) with an extremely clean burn.

The importance of the company's recent test is environmental in nature, but with major cost advantages. As a result of the low temperature burn of the gasoline -- as opposed to the extremely high temperatures produced in internal combustion engines -- the Cyclone engine produced little or no nitrogen oxide emissions, and kept carbon monoxide levels at a minimum. Additionally, the cylindrical design of the engine's combustion chamber effectively eliminated much of the unburnt hydrocarbons from the fuel source.

Nitrogen oxide, carbon monoxide and hydrocarbons are poisonous materials that are often controlled in internal combustion engines by means of catalytic converters. While all gasoline cars on the American roads are required to have this expensive component, few if any smaller engine applications, such as lawnmowers, contain a catalytic converter. This is one major reason why the U.S. Environmental Protection Agency has found that the 54 million Americans mowing their lawns each weekend with gas-powered mowers may be contributing as much as five percent of the nation's air pollution.

"The low temperature design of the Cyclone external combustion engine can help reduce the emission of noxious materials in our environment at a greatly reduced cost over current I/C solutions," stated Harry Schoell, Cyclone's CEO and engine inventor. "We believe that it's time our nation started to look closely at the advantages of Cyclone's technology over current alternatives."

About Cyclone

Cyclone holds the U.S. patent, international patent applications, and exclusive commercial rights to the Green Revolution Engine™, an environmentally friendly and highly efficient external combustion, heat-regenerative engine. Developed by Cyclone's President and CEO, Harry Schoell, the Green Revolution Engine regenerates (or recycles) its heat, which allows it to run cleaner, cooler and more efficiently than traditional internal combustion engines. It is capable of running on any liquid or gaseous fuel, including ethanol and propane, and is lubricated with de-ionized water instead of motor oil. By eliminating many subsystems like oil pumps, radiators, catalytic converters and fuel injectors, Cyclone's Green Revolution Engine is expected to cost less to manufacture, operate and maintain; however, it is highly scalable and sufficiently powerful for applications ranging from lawn equipment and small home generators, large stand alone generators, to cars, trucks, buses, RVs, boats and ships, as well as earth moving equipment and locomotives.
