Cummins Westport’s 8.9-Liter ISL G Engine
Available for T680, T880 and T880S Trucks
Kenworth’s T680 on-highway flagship tractor and its T880 and T880S vocational vehicles are available for order with the super low-NOx, ISL G Near Zero natural gas engine by Cummins Westport.
The 8.9-liter engine is rated at 320-horsepower with 1,000 foot-pounds of torque, Kenworth says, noting that the ISL G NZ is certified by both the U.S. EPA and California Air Resources Board for nitrogen oxide emissions of just 0.2 grams per brake horsepower-hour – 90% below the 2.0 g/bhp-hr standard (F&F, September 17, 2015).
“The new engine uses advanced engine calibration, a unique maintenance-free, three-way catalyst after-treatment system, and a closed crankcase ventilation system to help achieve this reduction,” Kenworth said this week.
‘Ideal for Regional Haul, Vocational and Refuse Fleets’
“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,” Kenworth marketing director Kurt Swihart said in this week’s Near Zero announcement.
The trucks can be either CNG/compressed natural gas- or LNG/liquefied natural gas-fueled.
The natural gas option for the T880 was first offered three years ago (F&F, August 18, 2014).
