Peterbilt to Offer Three Factory-Installed Heavy-Duty LNG Configurations

Peterbilt Motors Company will offer three new liquefied natural gas (LNG) configurations on its Models 387, 386 and 367 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.

Peterbilt trucks were part of Westport’s first heavy-duty LNG 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. To date, more than 50 Model 320 CNG Trucks are in operation throughout the US.

Based on the Cummins ISX diesel engine with cooled EGR, Westport’s ISX G engine offers 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 Westport LNG system is 2007 EPA and CARB certified to 0.8 g/bhp-hr NOx and 0.01 g/bhp-hr PM.

The Westport ISX G engine is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque for heavy-duty port, freight and vocational applications.

It has been most surprising that the railroads have not started using LNG or CNG co-fuels in their locomotive to a high degree. A Dutch company can supply a simple liqufier. It would be interesting to see wether CNG is or LNG is more energy efficient for trucks or locomotives. Heavy CNG tankers can be put behind a locomotive with ease. ..HG..

Cool. Are these dual fuel (diesel and NG)? If not, could someone explain why?
