Kenworth Truck Company has made its second natural gas announcement of August announcing the availability of the Cummins ISX12N near zero NOx emissions natural gas engine for the T680, T880 and T880S models.

The ISX12N is certified by the Environmental Protection Agency and the California Air Resources Board. The engine meets CARBs optional low NOx standard of 0.02 g/bhp-hr which represents a 90 percent reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr, the company says.

”The Cummins Westport ISX12N provides an excellent, very low-emissions solution for fleets and truck operators that order the Kenworth T680, T880, and T880S for line haul, regional haul, vocational and refuse applications,” says Kurt Swihart, Kenworth marketing director.

In addition to offering ultra-low emissions, Kenworth says the ISX12N engine features a closed crankcase ventilation system, unique maintenance free three-way catalyst, on-board diagnostic capability and engine control module with excellent durability.

The Kenworth T680, T880 and T880s offer the 12-liter ISX12N ratings with 400 hp and 1,450 lb-ft of torque. The engine can operate on compressed natural gas and liquified natural gas as well as renewable natural gas, which offers additional reductions in GHG emissions. RNG is produced from the decomposition of organic waste from such sources as dairy farms, landfills, and urban waste treatment plants, the company says.
