Scuderi Presents New Engine Design at SAE World Congress

After various lab tests conducted by engine development company Scuderi Group, a new engine design is finding its way into the world. A re-engineered conventional four-stroke has been presented today at the SAE World Congress, one that benefits from a technology that enables maximum levels of power and torque while reducing the rate of fuel consumption and engine size.

Studies have concluded that the new engine design, when boosted with a turbocharger to 3.2 bar, decreases the BSFC (or brake specific fuel consumption) up to 14 percent, as a simultaneous increase occurs in the engine’s power BMEP (or brake mean effective pressure) by 140 percent. At the same time reducing the size of the engine over 29 percent.

The Scuderi Engine has two high-pressure strokes—compression and power, and two low-pressure strokes—intake and exhaust. The power stroke is positive work, or the energy that is produced by the expanding gases to create mechanical work. The intake, compression and exhaust strokes are all negative work, or the energy that the engine consumes to create mechanical work.

By separating the compression cylinder from the power cylinder and by using a standard turbocharger to convert recovered exhaust-gas energy into compressed air energy, the size of the compression cylinder can be downsized to achieve substantial reductions in negative compression work.

“The Scuderi Engine gains a massive advantage from turbocharging, Miller-like valve control strategies and extended expansion that is simply not possible with conventional engine designs,” said President of Scuderi Group, Sal Scuderi. “The net result is a smaller, higher-performing engine that yields significant gains in volumetric efficiency and power as well as reducing BSFC.  Studies are underway at the lab that will be announced in the coming weeks, that will show impressive results of the Scuderi Split-Cycle engine modeled in a 2011 Nissan Sentra."
