Kenworth Truck has boosted the operating range of its natural gas powered T800 Day Cab and Extended Day Cab models by offering an additional 60 diesel gallon equivalent LNG fuel tank as a buyer option. Equipped with dual Liquefied Natural Gas (LNG) tanks and 15-liter Westport GX engines from Westport Innovations, the trucks will double their range to 700 miles (1126 kms), increasing versatility and appeal for long distance truck fleets.
“This option doubles the operating range of a typical LNG-powered Kenworth T800 equipped with a single LNG tank, making the truck a better choice for long haulers with slip-seat or drop-and-hook operations and for regional haulers whose drivers travel long distances, but still return home at the end of their shifts,” said Kenworth vocational marketing manager Alan Fennimore said in a release at the Great American Trucking Show.
The natural gas Kenworth T800 can be ordered in a gross combination weight (GCW) of up to 80,000 lbs. for over-the-road operation, with additional ratings exceeding 100,000 lbs. available for certain applications. The Westport GX engine is available in power ratings from 400 to 475 hp and torque ratings from 1,450 to 1,750 lb-ft, delivering similar power and torque to its diesel engine counterparts.
Fennimore said the optional tank will enable fleet operators to take full advantage of the expanding LNG fueling infrastructure being opened up across the United States by Shell, Clean Energy, Chesapeake and others.
According to a Fleets & Fuels article, the LNG tanks are manufactured in China by BTIC Westport, a joint venture of Westport Innovations and Beijing Tianhai Industry Company.
In July, Kenworth officials provided information about a proposed heavy-duty natural gas push beginning 2013. The company’s natural gas model range will be boosted by the addition of the new Cummins ISX12G 12-liter natural gas engine, which will initially be offered in the Kenworth T660.
