Cummins retiring 2 engines and adding new X10

Cummins Inc. will retire its L9 and X12 legacy engines, changing them with a new X10 motor able of powering medium- and hefty-obligation vehicles on a variety of fuels.

The go is constant with Cummins’ prepare to present its X15 engine spouse and children driven by natural gasoline, hydrogen, propane and possibly other combustible fuels as an interim resolution alongside with zero-emission battery- and gas mobile-electric powered powertrains.

The fuel-agnostic motor platforms attribute a collection of motor variations derived from a prevalent foundation motor. Down below the head gasket, each individual engine has identical components. Components over the head gasket comprise components for diverse gasoline styles. Each individual engine operates on a person gas.

New Cummins motor slots among medium- and heavy-responsibility programs

The 10-liter displacement product slots among the B6.7 for vocational, transit, pickup and delivery and regional haul shoppers and the X15 targeted on extensive-haul trucking. The X10 will get started as a diesel motor and incorporate other gaseous fuels, which include B20 and renewable diesel.  

Cummins programs to present the X15N powered by natural fuel in 2024 and the X15H with hydrogen combustion in 2027.  

“We are committed to advancing diesel technology when our marketplaces and our customers require it to operate their businesses,” José Samperio, Cummins govt director of the North The united states On-Highway business, explained in a information launch.

New engine emits 75{09e594db938380acbda72fd0ffbcd1ef1c99380160786adb3aba3c50c4545157} less NOx emissions

The new X10 diesel will emit 75{09e594db938380acbda72fd0ffbcd1ef1c99380160786adb3aba3c50c4545157} fewer nitrogen oxide emissions than present engines and comply with the U.S. Environmental Protection Agency 2027 rules. The X10 architecture takes advantage of a belt-pushed, superior-output 48-volt alternator. An aftertreatment heater is scalable to other superior combustion technologies this kind of as cylinder deactivation.

Cummins obtained Jacobs Automotive Techniques, a maker of cylinder deactivation technologies, in 2022. It also partnered with startup Tula Technological know-how to exam diesel Dynamic Skip Fire technology that minimized NOx emissions by 74{09e594db938380acbda72fd0ffbcd1ef1c99380160786adb3aba3c50c4545157} in the X15 engine.

“It will be scalable to other sophisticated combustion technologies, but it is far too early to say which may be applied,” spokesperson Katie Zarich instructed FreightWaves.

The engine can be paired with various transmissions, such as the Eaton Cummins Endurant for greater drivability and effectiveness from idle to comprehensive ability. The X10 has lengthier upkeep intervals, lowering visits to the store. More than-the-air calibration, predictive provider suggestions and other features come through Cummins’ Acumen electronic connectivity.

The new engine will first be readily available in Europe and North The usa. Other locations will get it later and an off-freeway edition is portion of the extensive-time period approach.
