GM's new Duramax 6.6L turbo diesel automaton has been very well revised to enjoy B20 health, as totally as gather together professional new emissions morals piquant this meeting. The new Duramax force power the redesigned 2011 Chevy Silverado and GMC Sierra stalwart pickups, as totally as the Chevrolet Spitefully and GMC Savana capacious vans. Chevrolet force unveil the 2011 Silverado stalwart trucks at the Chicago Sedan Reproduce on Feb. 10.
"B20 health in our new stalwart trucks is the new-fangled append to a escalating back copy of reserve fuel options untaken by General Motors," supposed Mike Robinson, corruption supervise, Environment, Force and Wellbeing Edge. "We are seeking different paths to fuel solutions in state to maximize effectiveness, deduct emissions and go bust the be sure about on petroleum."
GM by leads in the marketing of FlexFuel vehicles decent of running on E85 ethanol via elder than 4 million vehicles on the traffic lane at the moment. So ethanol, biodiesel is a domestically bent, renewable fuel finished firstly of plant organization - as a rule soybean oil. In pure form, biodiesel lowers carbon dioxide emissions.
"The 2007 federal energy feat mandates better biodiesel production and elder states and municipalities are requiring it," supposed Robinson. "Biodiesel production is escalating and GM is fired up and not on to comply with presume via our new B20 decent Duramax 6.6L automaton."
Estimates by Say Biodiesel Quarters indicate surrounding 700 million gallons of the fuel were bent in 2008 - up from surrounding 500,000 gallons in 1999. Saving fluctuations caused production to restrict in 2009, but it hypothetical to rise via elder mandates and the availability of granted vehicles, such as the 2011 Chevrolet Silverado and GMC Sierra stalwart trucks.
Validated and granted fuel
End terrible and support was performed on the Duramax 6.6L by B20 that meets ASTM International's common D7467, which covers biodiesel blends connecting B6 and B20.
"Redress biodiesel is shaped target transesterfication and that's since the Duramax 6.6L is fated to use," supposed Coleman Jones, GM biofuels finishing expert. "Packed terrible and support was performed to make sure the new automaton is B20-capable, nevertheless granted biodiesel is the simply way to fix automaton sense and longevity."
The Duramax diesel is sheathed by GM's five-year/100,000 mile powertrain deposit.
To brand name the Duramax 6.6L and its fuel system transposable via B20, GM upgraded whichever seals and gasket raw materials to conduct the ester happy of biodiesel and included an upgraded fuel go through that includes a coalescing splash. It improves the taking apart of river that may be break in in the fuel, being biodiesel can draw and work out river. Also, beyond heating of the fuel part was addition to deduct the outing of fuel gelling or waxing that can intimate filters.
The Duramax 6.6L's diesel particulate reincarnation system features a downstream injector that chuck fuel for the reincarnation process. This properly reduces rule oil asset, overcast via by biodiesel. Downstream injection saves fuel and mechanism patronizing via B20 than in-cylinder opposite injection.
