Kenworth Truck Company will expand its presence in the growing market for environmentally friendly, liquefied natural gas (LNG) vehicles by beginning production of Kenworth T800 LNG trucks at its manufacturing facility in Renton, Wash., in 2009.

Under an exclusive agreement with Westport Innovations Inc., Kenworth will use Westport's LNG fuel system technology adapted for the Cummins ISX-15-liter engine.

Westport will open a new LNG fuel system assembly center in British Columbia, Canada 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.

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.

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.
