The Scuderi Group arrived on Tuesday for the opening of the 2008 Engine Expo in Stuttgart, Germany, Europe’s
premier trade show focusing on engine design and development. This is
the third consecutive year the Scuderi Group and its Air-Hybrid Engine
have participated in the event.
Sal Scuderi presents his talk during the Open Technology Forum held Tuesday at Engine Expo in Stuttgart, Germany.
The company had on display for the first time a model of what it claims is
world’s most fuel efficient internal combustion engine, its unique and highly promising split-cycle air-hybrid engine. The
Scuderi split-cycle arrangement and valve train technology changes the heart of the conventional
engine by dividing (or splitting) the four strokes of the Otto cycle
over a paired combination of one compression cylinder and one power
cylinder. Gas is compressed in the compression cylinder and transferred
to the power cylinder through a gas passage.
The gas passage
includes a set of uniquely timed valves, which maintain a precharged
pressure through all four strokes of the cycle. Shortly after the
piston in the power cylinder reaches its top dead center position, the
gas is quickly transferred to the power cylinder and fired (or
combusted) to produce the power stroke.
By splitting the strokes of the Otto cycle over a pair of dedicated
compression and power cylinders, the design of each cylinder can be
independently optimized to perform the separate and distinct tasks of
compression and power. As a result, the split-cycle design provides
more flexibility in how engines are built. Features that were
understood to be beneficial but impossible to implement in a
conventional design can be implemented in the split-cycle design.
Another highlight of the day was a presentation by Scuderi Group
president Sal Scuderi to a packed Open Technology Forum where he
participated in the Reducing Emissions track. Titled, “Air Could Be the
Answer,” Sal explored the idea of using compressed air to reduce
vehicle emissions. In his presentation, he highlighted that the Scuderi
Air-Hybrid - with its air tank that captures wasted energy in the form
of compressed air - has the potential of increasing fuel efficiency to
historical levels and reduce the release of NOx by up to 80 percent
compared to all the vehicles on the road today. He also discussed how
the Air-Hybrid is expected to have considerably more torque an power
over conventional engines with minimal manufacturing and retooling
costs.
