Cummins has announced that it will market a 15-liter natural gas engine for heavy-duty trucks.

The 15-liter engine will offer ratings of up to 500 hp and 1,850 lb-ft of torque. He should weigh 500 lbs. less than comparable 15-liter diesel engines currently on the market, while not requiring selective catalytic reduction to meet California’s or the Environmental Protection Agency’s 2024 emission standards, said Cummins officials in a press release.

The 15-litre natural gas engine can be paired with the Eaton Cummins Endurant HD transmission and Cummins fuel system, ensuring a fully integrated natural gas powertrain.

Other transmission pairings will be available at launch for specialty applications, Cummins officials said.

When powered by renewable natural gas, using methane collected from organic waste as the primary fuel source, the system can be credited with a neutral to negative carbon index, resulting in net greenhouse gas emissions equal to or less than zero.

The overview

The 15-liter natural gas engine is an important part of Cummins’ strategy for its path to zero emissions. Expanding product line will help achieve Cummins environmental goals, including reducing emissions from newly sold products by 30% by 2030 and a goal of carbon neutrality by 2050, aligned with Accord goals of Paris on the climate.

“We believe this natural gas option is a game-changer as an economical power option for existing diesel powertrains in heavy-duty trucks, making it an excellent complement to reduce CO2 emissions,” Srikanth said. Padmanabhan, president of Cummins’ engine business, in a press release.

The launch of the universal 15-liter heavy-duty platform ensures a full range of natural gas powertrains are available to meet customer and end-market emission reduction goals, Cummins officials said.

The engine is also the basis of Cummins’ recently announced hydrogen internal combustion engine, which is currently being tested.
