Emission regulations have become crucial in reducing the environmental impact of heavy-duty vehicles. The implementation of U.S. Environment Protection Agency’s (EPA) 2027 emission standards in North America is expected to be a significant milestone in this ongoing endeavor, drastically lowering nitrogen oxide (NOx) emission limits by over 80%.

As fleets work towards reducing emissions, understanding the differences in aftertreatment systems for various fuel types is crucial. The adoption and growth of hydrogen internal combustion engines (ICE) is a significant step as hydrogen ICE provides a low-emission, low-carbon option for a more sustainable transportation sector.

76,558 miles. 1,475 hours. 114 days. 33 city stops. 5 trucks. 9 professional drivers. When I woke up in Nashville, Tennessee on Saturday, October 3rd, there was only 1 day, 287 miles and 5 hours to go.

In April 2022, Cummins Inc. announced the acquisition of Jacobs Vehicle Systems (JVS), a supplier of engine braking, cylinder deactivation, start and stop and thermal management technologies. Not only did this addition to Cummins’ vast portfolio of advanced technology for engines bring ownership of JVS’s new technologies to the company’s current and future advanced engine platforms, it allowed Cummins to finally acquire ownership of Clessie Cummins’ very own invention from the 1950s, the Jake Brake®.

After working with Cummins Inc. and other major industry suppliers to slash emissions with a hydrogen internal combustion engine (H2-ICE), Southwest Research Institute is moving onto the next phase of its H2-ICE Consortium - drawing on real-world expertise from fleets.

Global power and technology leader Cummins Inc. (NYSE: CMI) has started full production of the X15N™ natural gas engine at its Jamestown Engine Plant. The Cummins X15N is the first 15-liter natural gas engine to be designed with flexibility to perform across a range of heavy-duty applications, including line haul and vocational.

The industries Cummins Inc. powers play a critical role in impacting climate change.
