Peterbilt LNG-fueled engines

| January 18, 2012

Peterbilt will offer three new engines fueled by liquefied natural gas on its Models 387, 386 and 367 in 2009. The factory-installed LNG system is part of a joint agreement with Westport Innovations to provide natural gas versions of select Peterbilt aerodynamic and vocational vehicles. Westport’s ISX G engine and LNG fuel system for Class 8 trucks allows trucking fleets to move to lower-cost, domestically available natural gas and/or biogas while offering industry-leading emissions. Components in the system include LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components.
