|The Kenworth T800 LNG truck.|
Kenworth Truck Company will begin production of Kenworth Class 8 T800 LNG trucks at its manufacturing facility in Renton, Washington in 2009. Under an exclusive agreement with Westport Innovations Inc. in Vancouver, B.C., Kenworth will use Westport’s LNG HPDI fuel system technology adapted for the Cummins ISX 15-liter engine.
HPDI uses a small amount of diesel to ignite the natural gas in the engine and provides diesel-equivalent torque, horsepower and a range of 400-450 miles. (Earlier post.)
The Westport LNG system comprises LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components to facilitate robust performance and reliable operation. The Westport LNG system is 2007 EPA and CARB certified to 0.8g/bhp-hr NOx and 0.01g/bhp-hr PM.
The Westport LNG system is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque for heavy duty port, freight, and vocational applications. LNG fuel tanks can be configured to suit customer range requirements. Trucks are eligible for federal tax credits in the United States and may be eligible for other state-specific emissions credits.
The Kenworth LNG factory installation coincides with the Ports of Los Angeles and Long Beach announcement to approve a new $1.6 billion Clean Truck Superfund. The fund will assist replacing many of the 16,800 Class 8 trucks serving the ports with LNG-powered vehicles. (Earlier post.)
The ports have also introduced a new progressive ban that will remove all pre-2007 trucks by 2012. Westport’s LNG fuel system is the only alternative fuel technology currently qualified for financial support under the ports’ Clean Truck program.
Kenworth and Westport Innovations have previously collaborated on an aftermarket basis to equip Kenworth T800s with LNG fuel systems. These trucks are already serving the Ports of Los Angeles and Long Beach. In addition, Pacific Gas & Electric Company in San Francisco recently became the first utility in the nation to operate Kenworth T800 LNG-powered trucks. (Earlier post.)
Westport will open a new LNG Fuel System Assembly Center in British Columbia to support the Kenworth factory initiative and to rapidly increase production capacities of LNG fuel systems to meet growing market demand. The Westport Assembly Center will facilitate significant capability for fuel system assembly and engine conversions for delivery direct to the Kenworth plant.
