Cummins Inc. unveils EPA 2021 B6.7TM and L9TM medium-duty engines at WTS20

3/3/20

Cummins Inc. introduced its next generation of medium-duty on-highway power solutions, showcasing advanced diesel and natural gas engines at The Work Truck Show in Indianapolis, Indiana.

Cummins’ medium-duty advanced diesel engines are designed to meet EPA 2021 emissions requirements while building upon more than three decades of performance, reliability, and durability, backed by the best warranty and extended coverage plans in the industry and the largest, most capable support network in North America.

“The Work Truck Show is an excellent venue to introduce the next generation Cummins B6.7TM and L9TM” said Rob Neitzke, EBU OEM Leader for Cummins. “Work Truck and Vocational users operate under some of the most severe duty cycles and expect their truck engines to deliver the power and performance to get the job done.”

The 2021 B6.7 (pictured left below) and L9 (picture right below) will provide customers with dependable, efficient solutions for vocational and specialty applications, as well as pick-up and delivery, regional haul, school bus, transit bus and emergency vehicle applications.

     

“We focused on making the engines even more reliable, and more efficient. We want to help users keep them on the road longer between scheduled maintenance intervals. We also were mindful to ensure we delivered the performance standards users expect from Cummins,” Neitzke said.

Enhancements to the next generation of B6.7 and L9 engines were made with customers’ total cost of ownership in mind. Both engines feature extended oil drain and fuel filter replacement intervals, and a redesigned breather that is now maintenance-free.

Base engine hardware improvements and advancements in air handling for the L9 deliver up to 5% better fuel economy when compared to the 2017 L9 engine model.  For truck applications, the 2021 L9 base warranty is now three years / unlimited miles, for added peace of mind.

Cummins Westport Natural Gas Technology
Cummins’ commitment to deliver sustainable products and lower NOx emissions continues with the Cummins Westport B6.7N natural gas engine, which recently received certifications from both the U.S. Environmental Protection Agency (“EPA”) and Air Resources Board (“ARB”) in California. 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.

The full Cummins Westport natural gas engine portfolio now meets this optional Low NOx standard.

“We’re proud to continue our legacy of emissions-leading products,” said Gordon Exel, President, Cummins Westport Inc. “The B6.7N is an excellent choice for medium-duty customers looking to reduce greenhouse gas emissions and lower their overall environmental footprint without sacrificing performance.”
