Kenworth adds Near Zero 12 liter Natural Gas Engine to 3 models

The Kenworth T680, Kenworth T880 and T880S  are available for order with the Cummins Westport ISX12N near zero NOx emissions natural gas engine.

This engine is certified by both the Environmental Protection Agency and California Air Resources Board (CARB); it meets CARB’s 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. In addition, 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 Cummins Westport ISX12N provides an excellent, very low-emissions solution for fleets and truck operators that order the Kenworth T680, T880 and T880S for service in line haul, regional haul, vocational and refuse applications,” said Kurt Swihart, Kenworth marketing director.

These Kenworth trucks  can operate on compressed natural gas (CNG) and liquefied natural gas (LNG), as well as renewable natural gas (RNG), which offers additional reductions in GHG emissions. It has been demonstrated that the Near Xero engines operated with RNG are cleaner than similar electric trucks over their life cycle.
