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.

Kenworth noted this week that it showed a new T880S mixer – its first truck equipped with the Cummins Westport ISL G Near Zero emissions engine –at the Alternative Clean Transportation (ACT) Expo this past May in Long Beach, Calif. (F&F, April 21). Catalina Pacific is the operator and McNeilus supplied the ‘NGen’ fuel system for the truck shown at ACT Expo 2017.



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).
