Peterbilt To Offer Westport Innovations LNG Options

Posted on October 14, 2008

Peterbilt Motors Co. has announced it will offer three new liquefied natural gas (LNG) configurations on its Models 387, 386 and 367 trucks beginning in 2009. The factory-installed LNG system is part of a joint agreement between Peterbilt and Westport Innovations Inc. to provide natural gas versions of select Peterbilt aerodynamic and vocational vehicles.

“LNG is emerging as an alternative clean, high-performance fuel for trucks that is domestically available and economical,” said Bill Jackson, Peterbilt General Manager and PACCAR vice president. “Peterbilt is committed to delivering products that reduce harmful emissions and realistically provide the performance and economics that our customers need,”

Michael Gallagher, President and Chief Operating Officer of Westport added, “Peterbilt is a strong commercial production partner and brings a high level of expertise and production capacity to meet the increasing interest for LNG trucks. Peterbilt trucks were part of our first road trials, in a field test with Norcal Waste in San Francisco in 2001.”

More recently, Peterbilt and Westport have collaborated on a project to build Model 386 LNG evaluation trucks for Wal-Mart under a funding program with Mojave Air Quality Management District. The LNG Models 387, 386 and 367 complement Peterbilt's existing Model 320 CNG vehicles.

Westport's ISX G engine and LNG fuel system for heavy-duty Class 8 trucks is based on the Cummins ISX diesel engine with cooled EGR. The LNG version of the engine is designed to offer the same horsepower, torque, and efficiency as the base diesel engine it is replacing. The Westport LNG fuel system comprises LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components. The system is 2007 EPA and CARB certified.
