Kenworth is adding the Cummins Westport L9N near zero NOx emissions natural gas engine as an option for its T680, T880 and T880S 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 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.
