Split-cycle engine

  • 06-Jul-2009 12:15 EDT

The Scuderi Group’s split-cycle engine is a one-liter, naturally aspirated gasoline prototype that is expected to produce up to 80% fewer toxins than a typical internal combustion engine. When fully developed with its turbocharged and air-hybrid components, the engine should achieve significant gains in fuel efficiency. The split-cycle design divides the four strokes of a conventional combustion cycle over two paired cylinders: one intake/compression cylinder and one power/exhaust cylinder. By firing after top-dead center, it produces highly efficient, cleaner combustion with one cylinder and compressed air with the other. The engine requires just one crankshaft revolution to complete a single combustion cycle. Studies show that it can produce more torque than conventional gasoline and diesel engines. The technology provides OEMs an immediate solution for complying with higher emissions and efficiency standards without having to make large investments to modify current production processes. Completion of the turbocharged Scuderi engine and air-hybrid are expected in 2010.
