The technology evolved around the development of a stepped-piston, intricate combustion chamber and the incorporation of a direct fuel-injection system for a single cylinder, air-cooled engine of 125 cc. It produces improved performance over a same conventional two-stroke engine of similar displacement and lower emission (lower concentration of NOx. CO2, CO and HCs) levels and smoke. The design enables the engine capacity to expand in modular forms, from 125cc to 500cc with minor modifications.
