PACCAR to Offer Cummins X15N Natural Gas Engine

PACCAR will work with Cummins Inc. to offer the new Cummins X15N natural gas engine in Kenworth and Peterbilt trucks. The X15N is the first natural gas engine specifically designed for heavy-duty truck applications with up to 500 hp output. The engine will include the integration of the Cummins Clean Fuel Technologies fuel delivery system.

“PACCAR can help customers achieve their business goals by offering sustainable, affordable power solutions that use proven engine technology and existing infrastructure,” says John Rich, PACCAR chief technology officer.

PACCAR, Cummins, and several customers will achieve lower carbon emissions for long-haul transport using internal combustion engine technology.

“The X15N is essential to our commitment to help customers reach net-zero greenhouse gas emissions and to improve NOx,” says Srikanth Padmanabhan, vice president and president, Cummins Engine Business. “Importantly for the customer, the X15N will reduce the cost of adopting low emissions technologies for their fleet and gives them the confidence to do so built on the strong foundation of more than 30 years of experience with natural gas.”

When operating on renewable natural gas, the X15N engine can achieve reductions in life cycle greenhouse gas emissions of trucks. This ranges from a 90% reduction to carbon neutral—or carbon negative—depending on the bio-source used for the fuel.

The new X15N is capable of lower NOx levels than the 2024 EPA and CARB standards. Equally impressive is the 1,850 lb-ft of peak torque output provided by the X15N. This will provide optimum performance when paired with Eaton Cummins Automated Transmission Technologies HD and XD Transmission.
