Scuderi Engine's Valve Train Sub-Assembly Tested by Independent Laboratory

Test Results of Performance Criteria Exceed Preliminary Expectations

DETROIT, MI--(Marketwire - April 15, 2008) - Reaching yet another significant milestone in its development of the world's most fuel efficient internal combustion engine -- The Scuderi Air-Hybrid Engine -- the Scuderi Group today announced that measured results from valve train test rig tests by an independent laboratory have exceeded expectations and have had a nearly perfect match to initial computer predictions of the engine. This announcement marks the first day of the Scuderi Group's participation in the SAE World Congress and Exposition at the Cobo Center, where they will be meeting with automotive engineers from around the world to discuss the latest developments of the much-anticipated Scuderi Engine (Booth 1337).

The newly developed valve train test rig is designed to fully actuate, test and measure all performance criteria of the Scuderi Engine's crossover valve train sub-assembly, prior to the final assembly of the first Scuderi Engine prototype. The crossover valve train is one of the most critical portions of the Scuderi Engine since it must actuate at greater than Formula 1 speeds. Testing on the valve train test rig is expected to continue through the month of April.

"The valve train on the Scuderi Engine has been one of the most scrutinized features of the engine since our debut here at SAE World Congress two years ago," said Sal Scuderi, president of the Scuderi Group. "The valve train test rig simulates every aspect of the engine's environment, minus the heat of combustion. Therefore the laboratory was able to fully actuate the crossover valves at all engine speeds under all load conditions, and compare measured results to the computer-predicted performance data."

The Scuderi Engine

The Scuderi Split-Cycle Engine is expected to provide significant improvements in the area of power, efficiency, and environmental protection. The results of state-of-the-art modeling and testing indicate:

--  Fuel efficiency 25-50 percent higher than in today's conventional
--  Nitrous emissions up to 80 percent less than that of today's gasoline
    and diesel engines
--  Improved performance of hybrid engines
--  Considerably more torque and power over conventional engines
--  Minimal increased manufacturing and tooling costs due to use of
    similar or common components

How the Scuderi Air-Hybrid Engine works

Through the addition of a compressed air storage tank and some controls, the Scuderi Engine can recover the energy that is normally lost when a vehicle is decelerated. To apply this principle in an electric-hybrid vehicle, a complex electrical system is needed that costs thousands of dollars and consists of generators, motors, and batteries.
