STERLING’S FIRST LNG TRUCK
Sterling Truck Corp. has rolled out a new tractor fuelled by liquid natural gas. The Set-Back 113 is aimed particularly at California port operations, but it can also find applications with utilities and municipalities. It’s a factory-built truck powered by the Cummins Westport ISL G engine.
Natural-gas technology can save an estimated $6000 in annual fuel and operating costs per truck, the OEM says, and in some jurisdictions there may be tax incentives as well.
The Cummins Westport ISL G is an 8.9 liter EGR engine, offering the lowest emissions available without sacrificing performance or efficiency. Available in ratings up to 320 hp, the ISL G already meets EPA 2010 standards with 85% lower NOx emissions than the C Gas Plus engine. It also sports a maintenance-free exhaust system with a three-way catalyst. No further technology or aftertreatment will be required to meet 2010 emissions standards.
