PACCAR will work with Cummins to to offer the new Cummins X15N natural gas engine (previous article) in Kenworth and Peterbilt trucks. The X15N is the first natural gas engine to be designed specifically for heavy-duty truck applications with power up to 500 horsepower. The engine will feature fuel system integration from Cummins Clean Fuel Technologies.
PACCAR, Cummins and several customers, including FedEx Freight and Knight-Swift, will demonstrate their ability to reduce carbon emissions for long-haul transportation using internal combustion engine technology.
The X15N is essential to our commitment to help customers achieve net zero greenhouse gas emissions and improve NOX. Importantly for the customer, the X15N will reduce the cost of adopting low emission technologies for their fleet and give them the confidence to do so, building on the solid foundation of over 30 years of experience with the natural gas.
—Srikanth Padmanabhan, vice president and president, Cummins Engine Business
When running on renewable natural gas (RNG or biomethane), the X15N engine will be able to achieve significant reductions in greenhouse gas emissions throughout the life cycle of Peterbilt and Kenworth trucks. This can range from a 90% reduction to being carbon neutral or even carbon negative, depending on the bio-source and the waste used to produce the fuel.
The new X15N is able to reduce NOX levels above 2024 EPA and CARB standards. The maximum torque output of 1,850 lb-ft (2,508 N m) provided by the X15N will deliver peak performance when paired with Eaton Cummins HD and XD Transmission automated transmission technologies.
