First Scuderi Engine Prototype Assembled

Most Significant Advancement in Internal Combustion in Over 130 Years

by Lenny Case

After several years of extensive research, development, and patent preparation, the Scuderi Group announced today the assembly of the proof-of-concept prototype for its Scuderi Split-Cycle Engine. The highly anticipated prototype will undergo further testing and analysis and will be officially unveiled to the automotive industry April 20 at the 2009 SAE World Congress in Detroit.

The one-liter, naturally aspirated gasoline prototype is expected to produce up to 80 percent less toxins than a typical internal combustion engine. And when fully developed with its turbo charged and air hybrid components, it is expected to achieve significant gains in fuel efficiency – the most since the inception of the Otto Cycle over 130 years ago. The introduction of the Scuderi split-cycle technology to the engine manufacturing industry is significant because it gives OEMs a new, cleaner burning solution to comply with tough emissions and efficiency standards going into effect around the world – without having to make significant investments to retool or modify current production processes. The original Scuderi Engine design was invented by Carmelo Scuderi (1925-2002).

The Scuderi Group expects further advancement of the technology once the greater engineering community begins working with the engine and makes modifications and improvements that will most likely take the efficiency to even higher levels.

“This is a very important milestone for the Scuderi Group as well as the Scuderi family,” said Sal Scuderi, president of the Scuderi Group. “This has been seven years in the making and we’re only just beginning to realize the potential that this technology holds. We are eager to conclude licensing discussions with OEMs, so we can see the engine come to life in a variety of vehicles and finally be able to give the driving public a more fuel-efficient and environmentally-friendly driving option.”

The basic Scuderi Engine 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. Additionally, by firing after top-dead center, it produces highly efficient, clean combustion with one cylinder and compressed air in the other. Unlike conventional engines that require two revolutions to complete a single combustion cycle, the Scuderi Engine’s combustion cycle is completed once per revolution. Besides the improvements in efficiency and emissions, test results have shown that the Scuderi Engine is capable of producing more torque than conventional gasoline and diesel engines
