kscarbel2 Posted July 6, 2017 Share Posted July 6, 2017 Heavy Duty Trucking / July 5, 2017 Kenworth’s T680 on-highway flagship and T880 and T880S vocational trucks are now available for order with the Cummins Westport ISL G Near Zero NOx emissions natural-gas engine. The 8.9 liter Cummins Westport ISL G Near Zero is rated at 320 horsepower and 1,000 lb.-ft. of torque. Emissions of the ISL G NZ are 90% lower than the current Environmental Protection Agency and California Air Resources Board NOx limit of 0.2 g/bhp-hr and also meet the 2017 EPA greenhouse gas emission requirements, according to Cummins Westport. The engine makes use of advanced engine calibration, a three-way catalyst aftertreatment system, and a closed crankcase ventilation system to help achieve lower emissions. The ISL G NZ can operate on either compressed natural gas or liquefied natural gas and is also compatible with renewable natural gas. “The Kenworth T680 and T880 specified with the ISL G Near Zero emissions engine are ideal for regional haul, vocational, and refuse fleets focused on decreasing their environmental impact and reducing operating costs,” said Kurt Swihart, Kenworth marketing director.
