Chrysler may use Fiat engine system in some U.S. models
September 13, 2009
BALOCCO, Italy -- Chrysler Group may incorporate Fiat's new MultiAir fuel-saving technology in some gasoline engines, Fiat sources say.
Fiat S.p.A. considers the variable valve timing system a breakthrough. The company says MultiAir improves power by about 10 percent and reduces fuel consumption 10 percent.
The MultiAir system provides direct control of air and combustion in engines, cylinder by cylinder and stroke by stroke, without using the conventional throttle. That saves energy wasted in traditional systems.
Fiat will offer its first MultiAir engine in Europe this month on the Alfa Romeo MiTo small hatchback.
The sources say Chrysler is considering MultiAir technology for these engines:
--
2.0- and 2.4-liter four-cylinder units produced by the Global Engine Manufacturing Alliance, which Chrysler operates with Hyundai and Mitsubishi. The engines are used in the Chrysler Sebring, Dodge Caliber and Avenger and Jeep Compass and Patriot. MultiAir units could arrive in late 2011.
-- The
Pentastar V-6 engine family now under development. The 3.6-liter Pentastar family will replace seven Chrysler engines. The new V-6 will debut next spring on the
2011 Jeep Grand Cherokee. MultiAir could be added in the second half of 2012.
