In line with Cummins’ commitment to sustainability, the new Cummins X15 engine is designed to accommodate low-carbon diesel fuels.

It can effectively utilize biodiesel blends of up to 20% and renewable diesel blends of up to 100%.

Cummins has been at the forefront of embracing renewable fuels and remains dedicated to furthering the adoption of higher biodiesel blends and renewable diesel.

These low-carbon diesel fuels have demonstrated effectiveness in reducing the carbon intensity of diesel fuel consumption.

Moreover, they are readily accessible within the existing fueling infrastructure, facilitating their widespread use in today’s transportation sector.

Eaton Cummins Endurant

Eaton Cummins Endurant transmissions, including the Endurant HD and XD series, are optimized to integrate seamlessly with the next-generation X15 powertrain.

These transmissions enhance efficiency and performance while ensuring a comfortable driving experience.

They boast best-in-class transmission lube change intervals of up to 750,000 miles and offer remote diagnostic capabilities.

Cummins-Meritor Drivetrain Systems

Cummins-Meritor drivetrain systems, such as the Cummins-Meritor 14X™ HE tandem drive axles, are engineered for superior performance, durability, and fuel efficiency.

Equipped with a proprietary Meritor lube management system (MLMS), these axles feature fast ratio options, fuel-efficient bearings, and high-efficiency spiral bevel gearing.

Additionally, Cummins-Meritor Permalube™ RPL drivelines reduce maintenance requirements and are capable of handling the high torque demands of modern downsped engine platforms.

What are the Cummins HELM™ Platforms?

The Cummins HELM™ platforms comprise multiple engine versions derived from a shared base engine, resulting in a commonality of certain components below the head gasket.

However, above the head gasket, each engine version boasts distinct components tailored to its specific fuel type.

Operating on a single fuel, each engine version offers unique capabilities.

The Cummins X15N, for instance, represents the natural gas variant and serves as the inaugural engine on the Cummins HELM™ platforms accessible to customers.

Notably, the HELM™ platforms encompass a range of engine platforms, including the B, X10, and Cummins X15 engine platforms.
