Cummins Advances Natural Gas, Hydrogen Engine

Cummins Inc.’s 15-liter natural gas engine is coming to the United States by 2024.

The engine was introduced in China earlier this year and can be paired with a Cummins Eaton Automated Transmission Technologies Endurant HD Transmission and Cummins Fuel Delivery System, ensuring a purpose-built and fully integrated natural gas powertrain. The 15-liter engine will offer ratings up to 500 horsepower and 1,850 foot pounds of torque and is expected to weigh 500 pounds less than comparable 15-liter diesel engines currently available on the market while not requiring Selective Catalytic Reduction (SCR) to meet 2024 California or Environmental Protection Agency emission standards.

The 15-liter natural gas engine is part of Cummins strategy for its path to zero emissions. It can run on either natural gas or hydrogen, something Cummins officials said makes it a versatile offering to heavy-duty truck makers depending on their chosen environmentally friendly engine.

“The 15-liter natural gas engine is an important part of our path to zero emission strategy, by offering a significant reduction in both criteria pollutants and greenhouse gases in a product that’s available today and utilizes existing infrastructure,” said Tom Linebarger, Cummins chairman and CEO, during a recent conference call with investor analysts.

“Equally exciting is that this engine is designed to accept a range of gases and renewable fuels, including hydrogen in the future. In fact, all of Cummins’ engine platforms are being designed with the same fuel flexibility.”
