Peterbilt enhances its natural gas vehicle leadership

Peterbilt Motors Company continues to be a leader in the market for natural gas-powered vehicles. Peterbilt has been manufacturing trucks featuring liquefied natural gas (LNG) and compressed natural gas (CNG) fuel systems since 1996. Peterbilt has earned a 40 percent market share of the commercial truck natural gas market, providing vehicle solutions for over-the-road, regional and vocational applications.

Peterbilt offers two natural gas engine platforms for the market. The Cummins Westport 8.9 liter ISL G with 320hp at 1,000 lbs of torque, features spark ignition, and a 3-way catalyst emission system that can be configured with either LNG or CNG fuel systems. The second platform is the Westport HD15 liter engine with 475hp and 1,750 lbs of torque and diesel pilot ignition, which is configured for the LNG fuel system only. 

Peterbilt will offer the new Cummins Westport ISX12 G in 2013. This engine will be rated up to 400hp and 1,450 lbs of torque. It features spark ignition technology, a 3-way catalyst, and can be configured with an LNG or CNG fuel system. Peterbilt’s three dedicated natural gas engine platforms offer an efficient and clean technology that will benefit customers in a wide range of applications.
