Cummins Westport natural gas engines meet low-NOx standards

Cummins’ commitment to deliver sustainable products and lower NOx emissions continues with certification of the Cummins Westport B6.7N natural gas engine. It recently received certifications from both the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB).

The B6.7N meets optional Low NOx standard of 0.02 g/bhp-hr, a 90% reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr.

Cummins introduced its next generation of medium-duty on-highway diesel and natural gas engines at the Work Truck Show in Indianapolis.

At the show, Cummins also announced enhancements to the 2021 B6.7 and L9 diesel engines. Both engines feature extended oil drain and fuel filter replacement intervals, and a redesigned breather that is now maintenance-free.

Cummins’ suite of Connected Solutions is built on an open digital platform that is interconnectable with diverse environments. The portfolio offers fleet management tools and cost-saving technologies designed to enhance the customer experience across product lifecycles.
