New Efficient Split-Cycle EnginePosted January 11
Split-cycle engines were invented many years ago by Carmelo Scuderi but were always less efficient than traditional internal combustion engines. Now, an updated design sees them overtake standard engines in terms of efficiency for the first time.
A split-cycle engine features pairs of cylinders working together. One cylinder is responsible for intake and compression and the other for combustion and exhaust. A crossover passage links each pair. The new Scuderi split-cycle engine incorporates an air storage tank in its design and is named the Air-Hybrid engine. The air tank enables some of the energy that would ordinarily be lost to be recaptured and used.
The Southwest Research Institute has been testing a 2 cylinder Scuderi Air-Hybrid for the past year. Not only has their testing found it to be more efficient than a standard combustion engine but it also produces far fewer harmful emissions. Up to 50% less carbon dioxide and 80% less nitrous oxide is released.
Scuderi's president, Sal Scuderi, expects efficiencies to improve even further as final amendments to the design are made. He also believes the engine will be easy for manufacturers to switch to because minimal re-tooling will be required. Scuderi are aiming to licence the engine and have it available for use by car makers within 3 years.
