Kenworth has announced the availability of a dual LNG tank for its Class 8 T800 series trucks (which are powered by Westport’s 15 liter GX engine). The tanks are multi-walled Dewar flask designs, which can hold up to 60 DGEs each. The added fuel capacity of this configuration allows for an operating range of 700 miles. Kenworth anticipates the added range of the dual configuration will allow truck operators that used to exceed the limitations of regional fueling infrastructure to reconsider the LNG option. The configuration is factory installed and backed by Kenworth’s base warranty. The LNG version of the T800 can be ordered in a gross combination weight (GCW) of up to 80,000 pounds for over-the-road operation and over 100,000 pounds for certain applications. The power and torque ratings of Westport’s GX engine are comparable to that of the stock PACCAR MX diesel engine. The GX offers power ratings from 400 to 475 horsepower and torque ratings from 1,450 to 1,750 pounds-feet. UPS currently operates LNG-powered Kenworth trucks from Salt Lake City and from Southern California to Las Vegas. As more LNG fueling stations come online, Kenworth says it expects the LNG option will become more attractive to truck operators.
