Cyclone compared these results from dyanamometer testing to summary results for conventional internal combustion diesel engines, provided by Bridge Analzyers, the manufacturer of the testing device Cyclone used. Cyclone found that today’s diesel engines typically emit between 30 and 80 times more NO_x than the Cyclone Engine running the same fuel.

Unlike conventional diesels, Cyclone Engines do not require any exhaust after-treatment. The Cyclone Engine burns its fuel at approximately 2,000 °F (1,093 °C), whereas NO_x forms at temperatures above 2,300 °F (1,260 °C)—ranges typical for both diesel and gasoline-powered internal combustion engines. Nor does the Cyclone Engine idle; when no power is required from the engine, it shuts off.

While it is difficult to compare these results with current EPA standards, we believe that future mass emission testing of our engines will demonstrate that we can exceed even the most stringent environmental standards without the need for costly exhaust treatment equipment.

With minor adjustments to our Mark II 18HP generator engine over the following months, we believe that our emissions readings will improve further. The external combustion engine is naturally cleaner than internal combustion engines, and we expect the Cyclone to set the standard for this class.

The company performed the tests at its Pompano Beach, FL facility using a Bridge Model 9005-03 Gas Analyzer, which uses electro-chemical sensors to measure NO_x.
