GM Announces B20 Biofuel Capacity For Brandnew, 2011 Duramax 6.6L Turbo Diesel motor fuel
By General Motors GRAPEVINE, Texas – GM voiced currently that its brandnew lineup of heavy-duty diesel pickups will have B20 biodiesel capacity. B20 fuel is a mix of 20-percent biodiesel and 80-percent conventional diesel motor fuel, which helps lower co dioxide emissions and lessens dependence upon inorganicsubstance. The announcement was made during the National Biodiesel Discussion. GM’s brandnew Duramax 6.6L turbo diesel motor fuel engine has been substantially revised to include B20 capability, as well as meet despotic new emissions standards in effect this year.
A new Duramax will energy a redesigned 2011 Chevy Silverado as well as GMC Sierra heavy-duty pickups, as well as the Chevrolet Express and GMC Savana full-size vans. Chevrolet will betray a 2011 Silverado heavy-duty trucks at the Chicago Automobile Uncover upon Feb. 10. “B20 capability in the new heavy-duty trucks is a latest addition to a flourishing series of swap fuel options offering by General Motors,” pronounced Mike Robinson, clamp president, Environment, Appetite and Safety Policy. “We are looking dissimilar paths to fuel solutions in order to showoff potency, reduce emissions as well as minimize the coherence upon petroleum.” GM already leads in a marketing of FlexFuel vehicles capable of running upon E85 ethanol with some-more than 4 million vehicles on the road currently. Like ethanol, biodiesel is a domestically constructed, renewable fuel made primarily of plant make a difference – mostly soybean oil. In pristine form, biodiesel lowers co dioxide emissions. Estimates by National Biodiesel House indicate about 700 million gallons of the fuel were c onstructed in 2008 – up from about 500,000 gallons in 1999. Market fluctuations caused prolongation to diminution in 2009, but it approaching to climb with some-more mandates and a availability of authorized vehicles, such as the 2011 Chevrolet Silverado and GMC Sierra heavy-duty trucks. Validated as well as approved fuel Endless testing and validation was achieved on the Duramax 6.6L using B20 that meets ASTM International’s standard D7467, that covers biodiesel blends between B6 as well as B20. A Duramax diesel is covered by GM’s five-year/100,000 mile powertrain guaranty. To have a Duramax 6.6L and the fuel system concordant with B20, GM upgraded alittle seals as well as gasket materials to wardoff the ester calm of biodiesel and enclosed an upgraded fuel filter which includes a coalescing component. It improves a subdivision of h2o which may be present in the fuel, since biodiesel can capture and absorb water. Also, one more heati ng of the fuel circuit was combined to revoke the chance of fuel gelling or waxing which could block filters. A Duramax 6.6L’s diesel particulate metamorphosis complement facilities a downstream injector which reserve fuel for the regeneration process. This greatly reduces potential oil dilution, important with using biodiesel. Downstream injection saves fuel and works better with B20 than in-cylinde r post injection.
