Sterling Truck Corp. introduced the Sterling Set-Back 113 with Natural Gas.

The natural gas-fueled tractor is ideal for port operations, as well as natural gas utilities and municipalities. This truck is powered by the Cummins Westport ISL G.

"Due to deterioration in air quality, the Ports of Los Angeles and Long Beach have embraced the use of alternative fuels in commercial vehicles. At the same time, utility companies and municipalities throughout North America have shown increased interest in green transportation technology," said Richard Shearing, manager of product strategy. "By introducing the Set-Back 113 with Natural Gas, we're giving our customers a hard-working truck that reduces both costs and environmental emissions."

The Cummins Westport ISL G, an 8.9-liter stoichiometric cooled-exhaust gas recirculation engine, offers low emissions without sacrificing performance and efficiency. Available in ratings up to 320 horsepower, the ISL G already meets EPA 2010 standards with 85 percent lower NOx emissions than the C Gas Plus engine and features high power-to-weight ratio with an optimized turbocharger. The ISL G also features a maintenance-free exhaust system with a three-way catalyst.

The Set-Back 113 with Natural Gas is on display at the Alternative Fuel Vehicles Institute show.
