Researchers have developed a new two-stroke engine notable for its low consumption and low level of pollutant emissions. The engine is the result of Powerful, a European project focusing on reduction in the engine’s weight and size using only two cylinders instead of the four used in the four-stroke engines currently on the market. Moreover, since it has fewer cylinders, the friction produced in the engine is reduced, increasing its mechanical output and, finally, its overall performance.

The validation tests proved its potential for reducing pollutant emissions and fuel consumption compared to the four-stroke version currently available on the market. The team studied the possibility of implementing new advanced combustion concepts as alternatives to the conventional diesel system, with very promising results. The research effort is now focused on the development of a boosting system that increases the actual levels of maximum power to the equivalent of a four-stroke engine.
