New design complements new generation of downsized vehicles
AUBURN HILLS, Mich., April 10 /PRNewswire/ -- FEV announced today it
has developed a new low-height cylinder head concept that allows a
reduction in the height of a classical design cylinder head by up to 15mm.
The new technology will be on display at the FEV, Inc. exhibit at the 2008
SAE World Congress, April 14 - 17, at Cobo Center in Detroit. The
announcement was made by Dr. Joachim Wolschendorf, Vice President, Vehicle
and Drivetrain Engineering Division and CTO, of FEV, Inc.
"This technology is an example of FEV's ability to look at innovative
ways to leverage conventional technologies to overcome practical production
barriers," said Wolschendorf. "Over the years, the variation in distance
from valve seat to camshaft centerline has been minimal. This new concept
offers distinct design advantages, particularly as OEMs focus increasingly
on downsizing vehicles and going to higher specific power."
The low-height cylinder head concept represents a 15 mm reduction in
head height. This reduction enables several engine modifications, such as
shorter valves, and a narrower cylinder V-angle that provide significant
additional packaging space in the engine compartment. Benefits also include
stiffer cylinder head structure and reduced valve stem forces, providing a
more robust and durable powertrain system. Other benefits include reduced
cylinder head bending, reduced valve stem diameter, in addition to its
shorter valve length.
The cylinder head was developed in Europe by FEV Motorentechnik, where
smaller, higher specific power vehicles have dominated the market for some
time. The technology is well suited for implementation in these types of
engines/vehicles. FEV has also implemented this technology in diesel
cylinder heads for high performance, where this technique contributes to
the achievement of engines with a power density greater than 100 kW/L [135
HP/L].
