Air Hybrid
WEST SPRINGFIELD, Mass., USA – The Scuderi Group, developer of the world’s most fuel efficient internal combustion engine, has announced that Bosch Engineering GmbH will assist in the prototype development of the Scuderi Air-Hybrid Engine. As one of the world’s leading engineering services companies, Bosch Engineering will apply its expertise to the development of the timing system for the gasoline and diesel prototypes.
Specifically, Bosch will assist the Scuderi Group and its independent laboratory in defining the technical requirements and supplying component specifications. The team will start by focusing on the Otto (spark ignition combustion) cycle and then address the diesel cycle.
"Bringing the top tier talent of Bosch Engineering to our team developing the Scuderi Air-Hybrid Engine provides exceptional engineering resources that will help advance the Scuderi Engine technology," commented Sal Scuderi, president of the Scuderi Group.
As announced recently, the first independent lab report has predicted that the Scuderi Split-Cycle Engine under full-load (FL) conditions provides higher power, torque, and efficiency ratings than are currently attainable by the conventional turbocharged engines used in vehicles today.
The Scuderi Engine
The Scuderi Split-Cycle Engine is expected to provide significant improvements in the area of power, efficiency, and environmental protection. The Scuderi Group has made these latest improvements by focusing on fluid and thermodynamics in the engine core. The results of state-of-the-art modeling and testing indicate:
Fuel efficiency 25-50 percent higher than in today’s gasoline and diesel engines
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 small compressed air storage tank with only a few control elements costing only a few hundred dollars, 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. The Scuderi air-hybrid, unlike electric hybrids, also has the unique ability to recapture energy from the engine’s exhaust stream. This makes it possible to also use the Scuderi air-hybrid technology in stationary applications such as in generators, an area of application in which the electrical hybrid is considered impractical.

Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France. Writing in the Inderscience publication International Journal of Automotive Technology and Management, they suggest that the adoption of HEVs might even slow development of more sustainable fuel-cell powered electric vehicles.
Jean-Jacques Chanaron Research Director within the French National Centre for Scientific Research (CNRS) and Chief Scientific Advisor at the Grenoble School of Management and Julius Teske at Grenoble, question strongly whether the current acceptance of hybrid vehicle technology particularly in the USA is in any way environmentally sustainable.
The researchers have analyzed the spread of this technology including the non-financial drivers for its adoption. They point out that most manufacturers are rapidly integrating hybrid electric vehicles into their technology portfolio, despite the absence of significant profitability.
They add that the misinformed craze for hybrid vehicles especially in the USA, and increasingly in Japan and Europe, and potentially in China, could represent a red light for more innovative technologies, such as viable fuel-cell cars that can use sustainably sourced fuels, such as hydrogen. They concur with earlier studies that suggest that hydrogen fuel cells will not be marketable in high volumes before at least 2025. This could, however, be too late for some models of climate change and emissions reduction. They also point out that even fuel cell technology has its drawbacks and much of the marketing surrounding its potential has emerged only from the hydrogen lobby itself.
