Dana Corporation Unveils 12-Volt 'Stop-Start' Technology for Better Fuel Economy and Reduced Emissions

Oct 21, 2002

    TOLEDO, Ohio, Oct. 21 /PRNewswire/ -- Convergence 2002, Booth # 520 --
Dana Corporation (NYSE: DCN) has developed a new starter/alternator which
enables "stop-start" technology with traditional 12-volt electrical systems.
Use of this technology, which is being developed for the light truck/SUV
market, results in improved fuel economy and reduced emissions.

    Dana's starter/alternator technology saves fuel by shutting off a
vehicle's engine when the vehicle comes to a stop and restarts it instantly
when the driver removes their foot from the brake pedal.  Restart occurs in
less than 300 milliseconds, resulting in extremely smooth operation.
"The benefits of this technology are obvious in stop-and-go, bumper-to-bumper
city traffic," Hickey said.  "If the vehicle isn't running, emissions are
reduced and fuel isn't consumed."
    The design utilizes switched reluctance technology and combines both a
motor and a generator into one unit.  Switched reluctance motors use no
magnets, making Dana's design more cost efficient.  The rotor is reduced in
complexity as compared to equivalent AC induction and DC magnet systems.  The
design generates no internal heat, and is significantly more efficient than
existing systems in low-speed generation.  It can operate on 12 to 300 volts
and has significant advantages over similar designs.
    "One of the most important advantages is that it can be engineered to
output from two kilowatts to 40 kilowatts using the same basic technology,"
said John Hickey, director of advanced product engineering for Dana's
Automotive Systems Group. "Our starter/alternator will start a V-8 engine on
12 volts and will work on existing vehicles."
    The starter/alternator can be programmed in a variety of ways.  For
example, in the event of frequent stops and starts in a traffic jam, the
system can be programmed to increase the time interval before the engine
    In addition to its fuel economy and emissions benefits, the
starter/alternator technology may provide a boost in bringing electric power
steering to market faster, due to its ability to power advanced electrical
    The starter/alternator provides maximum generation capability while at
idle.  As a result, a greater number of electronic systems such as steering
and cooling can operate while the vehicle is idling without causing a power
    "The ability of the starter/alternator to provide 'power demand matching'
means that, when used to power other advanced electronic/mechanical systems
such as electric power steering and intelligent cooling, the overall fuel
economy savings can be significantly increased," Hickey said.
