Engine maker Scuderi Group announced it will unveil a design of its new air-hybrid engine at the SAE World Congress next week. By recapturing fumes from the exhaust and storing energy in the form of compressed air, the Scuderi Air-Hybrid Engine doubles the fuel efficiency of today's conventional engines and reduces toxic emissions by up to 80 percent, the company said in a statement. The Scuderi Air-Hybrid Engine is adaptable to diesel and gasoline automobiles, commercial vehicles and any other applications powered by internal combustion engines. The Scuderi Technology improves how an engine converts chemical energy into mechanical energy. Unlike conventional engines, the Scuderi engine divides the four strokes of a standard engine (intake, compression, power, and exhaust) over a paired combination of one compression cylinder and one power cylinder. These two cylinders perform their respective functions once per crankshaft revolution, while conventional engines require two revolutions of the crankshaft to perform these same functions. The Massachusetts-based Scuderi Group was recently awarded $1.2 million in federal funding to further the development of its engine.
