Peterbilt Extends Natural Gas Engine Lineup

March 27, 2013

Peterbilt Motors Company announced the availability of the new 2013 Cummins Westport ISX12 G natural gas engine. Since 1996 Peterbilt has been manufacturing trucks featuring liquefied natural gas (LNG) and compressed natural gas (CNG) fuel systems solutions for over-the-road, regional, and vocational applications.

“With growing demand for natural gas engines, we are pleased to add the Cummins ISX12 G to our natural gas lineup,” said Bill Kozek, Peterbilt general manager and PACCAR vice president. “The pairing of the dedicated natural gas engine with Peterbilt provides customers exceptional fuel economy with an environmentally-friendly, domestically-sourced fuel that helps lower operating costs.”

Based on the Cummins ISX12 diesel engine, the ISX12 G is both Environmental Protection Agency (EPA) and California Air Resources Board (ARB) certified. The ISX12 G will not require a diesel particulate filter or a selective catalytic reduction system. Available in August 2013, the new ISX12 G engine features spark ignition technology, a 3-way catalyst, and will be available with a maximum 400 hp and max torque ratings of up to 1,450 lbs.
