More Peterbilt Tractors Now Available with CNG


Heavy-duty truck OEM Peterbilt says compressed natural gas (CNG) fuel systems are now available as options for its on-highway Model 579 and vocational Model 567 trucks.

The company notes that both CNG models use the 11.9-liter Cummins Westport ISX12 G natural gas engine, which is available in horsepower ratings between 320 hp and 400 hp and 1,150 lb-ft and 1,450 lb-ft of torque. The trucks are compliant with all U.S. Environmental Protection Agency and California Air Resources Board emissions regulations.

Quantum Fuel Systems Technologies Worldwide Inc. provides back-of-cab CNG storage systems for the Peterbilt trucks via its Q-Lite product line. The standard system can store 123 DGE of CNG, and Quantum's single- or dual-frame rail-mounted systems can also be added to reach 170 DGE or 216 DGE combined, respectively.

‘CNG configurations of our Models 579 and 567 are ideal for customers in short- and regional-haul, refuse and construction applications who desire a clean-burning, fuel-saving natural gas engine,’ says Robert Woodall, Peterbilt's director of sales and marketing.

The company says these CNG models will be in production later this year.
