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 to be specifically designed for heavy-duty truck applications with up to 500 horsepower 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,” said John Rich, PACCAR chief technology officer.
“The X15N is essential to our commitment to help customers reach net-zero greenhouse gas emissions and to improve NOx. 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,” said Srikanth Padmanabhan, Vice President and President, Cummins Engine Business.
The X15N engine will be able to significantly reduce the lifetime greenhouse gas emissions of Peterbilt and Kenworth vehicles while running on renewable natural gas, often known as RNG or biomethane. Depending on the bio-source and waste feedstock utilised to make the fuel, this can range from a 90 percent reduction to carbon neutral, or even carbon negative.
The new X15N can achieve lower NOx emissions than the EPA and CARB regulations for 2024. The X15N’s max torque output of 1,850 ft-lbs. is equally outstanding, and it will function best when partnered with Eaton Cummins Automated Transmission Technologies HD and XD Transmission.
