Preliminary Test Results of the Scuderi Engine Prove the Concept of Firing After Top Dead Center

FRANKFURT, Germany – Sept. 8, 2009 – Scuderi Group, LLC will announce next week that it has proven the revolutionary concept of Firing After Top Dead Center, a new thermodynamic process – the Scuderi Cycle – that has the potential to be the biggest advancement in internal combustion engines since the Otto cycle over 130 years ago.

Visit the Air-Hybrid Blog (http://www.scuderigroup.com/blog/) to listen to a podcast about the newly-proven Scuderi Cycle.

A press conference with Scuderi Group executives and engineers will be held at 2 p.m. on Tuesday Sept. 15 at the International Motor Show in Frankfurt (63rd IAA Cars) (http://www.iaa.de/) in Congress Center Messe Frankfurt (CMF) Illusion Room 2 and 3. A working, cutaway model of the prototype engine will also be on display in Hall 4.1, Stand No. A9.

The naturally aspirated, one-liter prototype is currently running and undergoing testing at an independent laboratory where preliminary test results have matched earlier computer simulation projections. Further testing will occur over the next several weeks as engineers continue to fine tune and adjust the prototype. Engine maps and other data are currently being made available to OEMs on a non-disclosure basis.

The Scuderi engine is expected to produce up to 80 percent fewer toxins than a typical internal combustion engine. The current naturally aspirated gasoline prototype is expected to reach efficiency gains of 5-10 percent more than any conventional engine on the road today. And when fully developed with its turbocharged and Air-Hybrid components, the engine is expected to achieve efficiency levels of 25-50 percent higher.

“Preliminary test results are very encouraging,” said Sal Scuderi, president, Scuderi Group. “The pressure curves produced from the combustion process of firing after top dead center are showing excellent results and torque levels remain very strong. We’re excited to see this progress and be able to introduce such a historical development at this year’s IAA event.”

Scuderi Cycle technology offers automotive OEMs a new and realistic solution for complying with higher emissions and efficiency standards going into effect around the world - without requiring large investments to modify current production processes. The Scuderi Engine was originally conceived and designed by Carmelo Scuderi (1925-2002).

The Scuderi Cycle is a split-cycle design that 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 in the other. Unlike conventional engines that require two crankshaft revolutions to complete a single combustion cycle, the Scuderi Engine requires just one. Besides the improvements in efficiency and emissions, studies show that the Scuderi Cycle is capable of producing more torque than conventional gasoline and diesel engines.

With the naturally aspirated engine prototype now running, Scuderi Group and its independent laboratory continue to work on the next prototypes. Completion of the turbocharged Scuderi Engine and the Scuderi Air-Hybrid are expected in 2010. For more information on the Scuderi Engine, visit www.ScuderiEngine.com.
