Cummins 15L Natural Gas Engine

Oct. 15, 2021

Cummins will bring to market a 15-liter natural gas engine for heavy-duty trucks.

The engine 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 company says. Other transmission pairings will be available at launch for specialized applications. The 15-liter engine will offer ratings up to 500 horsepower and 1,850 lb.-ft. 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 to meet 2024 California or EPA emission standards.
