The software will be used to develop cleaner-burning engines and potentially fuels in advance of impending regulations in the US and Europe, which call for limits on the size and number of soot particles emitted by passenger cars. This can shave days, weeks or months from a design cycle to get cleaner cars more quickly on the road.
Unlike conventional diesels, Cyclone Engines do not require any exhaust after-treatment. The external combustion engine is naturally cleaner than internal combustion engines, and we expect the Cyclone to set the standard for this class. Nor does the Cyclone Engine idle; when no power is required from the engine, it shuts off.
