Mollar International Develops Engine That Cleans The Air

DAVIS, Calif --Moller International, Inc. (OTCBB:MLER), the developer of the Skycar® aircraft, the Rotapower® line of rotary engines and the Aerobot® line of Unmanned Aerial Vehicles (UAV), today announced it has a solution to pollution problems caused by small internal combustion engines, including gas mowers and leaf blowers.

“The engine we have developed will revolutionize the small engine market in the United States,” Paul Moller, President of Moller International said. “The engine is about the size of a storage trunk, and is perfect for use in California because when its run with Ethanol, it not only lowers dangerous greenhouse emissions, but actually releases air cleaner than when it was initially used,”.

“We tested the engine and achieved remarkably low emission levels in recent test of its Rotapower® engine,” Moller continued. “With ethanol as the fuel, the toxic emissions generated by the Rotapower® engine were below the California Super-Ultra Low Emissions Vehicle (SULEV) standards as well as the ambient levels of some U.S. cities.”

The 530cc engine tested produced 22 hp at 4500 rpm with an air/fuel ratio of 20 and λ of 1.35. To the layman this means more power and distance for less money and cleaner air. The toxic emission levels, when used with ethanol, are as follows: Unburned hydrocarbons (HC) = .5 ppm or .0043 gm/hp-hr Carbon monoxide (CO) = 9 ppm or .03 gm/hp-hr Nitrous oxide (NOX) = 3 ppm or .016 gm/hp-hr

The carbon dioxide produced was 11%, which is 25% lower than with gasoline. Ambient carbon monoxide levels in the Los Angeles basin averaged 17 ppm over 8-hr for 144 days annually while the average annual HC level was at .8 ppm. In this case the Rotapower engine would help clean the air when used to power vehicles and equipment.

Previous tests of the Rotapower® engine using gasoline were witnessed by Dr. Andy Burke from the Institute of Transportation Studies (ITS) at the University of California in Davis. These tests showed that with gasoline the Rotapower® engine produced toxic emissions below the ultra low emission vehicle level (ULEV) without using an exhaust after-treatment (no catalytic converter required). This new data shows that the Rotapower® engine operating on ethanol meets the California SULEV standard also without exhaust after-treatment. The Company believes that applications using the Rotapower® engine running on ethanol could actually improve air quality in some cities in the US.

The Rotapower engine's low emissions, low weight and high power-to-weight advantages, make it very practical for a wide range of applications, including: personal watercraft, ATVs, and in other high-performance recreational vehicles. We also see major applications in industrial applications such as pumps, motor-generators, and auxiliary power units. Additionally, Moller International plans to equip the Skycar aircraft with these engines.
