Bosch Schaeffler assists Scuderi to develop air hybrid engine (figure)

The Scuderi Group revealed on September 25th that it is working in collaboration with several global engineering firms, including German-based Mahler, Schaeffler, Swedish Cargine Engineering, U.S.-based ConvergentScience, and Gates. These companies are supporting the development of the Scuderi Air-Hybrid engine, which features a Split-Cycle design. This innovative approach to internal combustion engines has the potential to significantly improve efficiency and reduce emissions.

Scuderi Air-Hybrid Engine Based in West Springfield, Massachusetts, with offices in Frankfurt, Germany, the Scuderi Group has built its reputation through advanced research, development, and patent licensing. The company claims that its Air-Hybrid engine technology represents a major breakthrough in engine design over the past few decades, offering a versatile solution applicable to any internal combustion engine. Earlier this year, Scuderi announced a partnership with Bosch Engineering GmbH to develop the fuel injection system for the Air-Hybrid engine. The newly announced collaborators are each contributing key components and technical expertise: - Mahler is supplying pistons. - Schaeffler is providing the valve mechanism. - Cargine Engineering’s pneumatic control valve plays a crucial role in the Split-Cycle design and gas-exchange chamber (cross-over chamber). - ConvergentScience is offering advanced CFD software for simulation and analysis, supporting critical research at the Scuderi Group's independent lab. - Gates is supplying engine belts. The Scuderi Air-Hybrid engine uses a unique Split-Cycle piston design, which allows for improved efficiency and performance. According to the company, the engine can achieve: - Superior fuel economy compared to current gasoline and diesel engines. - An 80% reduction in nitrogen oxide emissions. - Enhanced hybrid performance with greater torque and power output than traditional engines. - Minimal increase in manufacturing costs by using common or similar parts. The technology introduces a small compressed air storage tank along with control units, adding only a few hundred dollars to the cost. This setup allows energy recovery during deceleration, improving overall efficiency. Unlike most hybrid-electric systems, which rely on complex electronics like generators, motors, and batteries—often increasing costs by tens of thousands of dollars—the Air-Hybrid system offers a simpler, more cost-effective alternative.
