Recently, emission regulations formerly concentrated on the acknowledged major polluters, such as motor vehicle engine, have been extended to the smaller engines.This forced the two-stroke engines manufacturers to search for environmentally cleaner solutions. In this respect the most promising technology seems to be the adoption of direct-injection and the challenge is not to complicate excessively a power system which has in simplicity and low cost its best advantages.The paper reports on a two-stroke gasoline direct-injection engine prototype which even if equipped with a low-pressure fuel pump, provides high injection pressure values thanks to a Water-Hammer effect.The engine is a two-cylinders-water-cooled type and its design follows previous experiences on single-cylinder engines prototype.Once described the basic working principles of the proposed concept the engine realization phases and its running results on a test bed are presented.
