The Scuderi Group will introduce the design of an air-hybrid implementation of its split-cycle engine (earlier post) at the SAE World Congress in Detroit next week. Scuderi claims that the air-hybrid system doubles the fuel efficiency of todays conventional engines and reduces toxic emissions by up to 80%—all with a low-cost, easily manufactured design.
The Scuderi Air-Hybrid Engine is adaptable to diesel and gasoline automobiles, commercial vehicles and any other applications powered by internal combustion engines.
The air-hybrid leverages Scuderi’s split-cycle technology by recapturing and storing energy in the form of compressed air. Unlike conventional engines, the Scuderi Engine produces compressed air during its normal operation.
By adding a small air storage tank with some simple controls costing only a few hundred dollars, the Scuderi Engine recaptures energy normally lost during the breaking of a vehicle. This compressed-air system would supplant the motor/generator and battery systems of electric hybrids.
The first diesel and gasoline air-hybrid prototypes, under development at Southwest Research Institute, are expected to be completed by early 2007.
