Cummins Westport L9N Engine
Kenworth has introduced the Cummins Westport L9N near zero NOx emissions natural gas engine to its options for the T680 on-highway truck and T880 and T880S work trucks. The L9N engine is certified to the California Air Resources Board (CARB) optional low NOx standard of 0.02 g/bhp-hr ‒ a 90 percent reduction from engines operating at the current Environmental Protection Agency (EPA) NOx limit of 0.2 g/bhp-hr.

In addition to ultra-low emissions, the L9N features on-board diagnostic capability, a unique maintenance-free three-way catalyst, closed crankcase ventilation system, and an engine control module with excellent durability.
The T680, T880 and T880S offer the 8.9-liter L9N rated at 320 hp and 1,000 lb-ft of torque. The engine operates on 100 percent natural gas, which can be carried on the vehicle in either compressed natural gas (CNG) or liquefied natural gas (LNG) form. The engine is also compatible with renewable natural gas (RNG), which can provide even further reductions in GHG emissions.
“The Kenworth T680, T880 and T880S specified with the Cummins Westport L9N near zero emissions engine are ideal for pickup and delivery, vocational and refuse fleets focused on reducing their environmental impact and decreasing operating costs,” said Kurt Swihart, Kenworth marketing director.
