Cummins diesel engine platforms are expanding for 2020. The X15 engine offering for 2020 includes a new X15 Efficiency Series engine, a new Productivity Series offering and the Performance Series engine customers have come to depend on. The Cummins X12 platform will also have expanded availability.
“We believe that diesel technology will be the best solution for many of the markets we serve for decades to come,” said Brett Merritt, vice president, on-highway engine business at Cummins. “That’s why we continue to invest in and innovate our diesel platforms.”
The 2020 X15 Efficiency Series base engine hardware improvements and advancements in air handling deliver up to a 3.5% better fuel economy when compared to the 2017 X15 Efficiency Series engine model, Cummins reported. The X15 platform now offers oil drain intervals of up to 75,000 miles. Extensions of up to 80,000 miles with the use of Valvoline Premium Blue oil and up to 100,000 miles through the Cummins OilGuard program are available for improved uptime.
The 2020 X15 Efficiency Series also boasts new EX ratings that deliver expanded powertrain capabilities that can deliver up to an additional 1.5% fuel efficiency increase on top of the improvements gained through base engine hardware and feature enhancements, Cummins said. These ratings contain the full suite of powertrain features, including not only all prior ADEPT features but also new capabilities such as predictive gear shifting, predictive braking, dynamic power and on-ramp boost. Many of the powertrain features in the EX ratings are only available with the X15 Efficiency Series engine when paired with the Endurant transmission from the Eaton Cummins Automated Transmission Technologies joint venture.
The new X15 Productivity Series ratings are designed for multi-purpose, vocational and heavy-haul customers who look not only for efficiency in their powertrain but also the response and performance needed to get the job done thanks to a wider engine speed range.
In 2020, Cummins is offering the same X15 Performance Series engine with no changes to the product in 2020.
Cummins’ X12 engine, designed for customers with regional-haul, vocational and intermodal truck applications in mind, the X12 engine is the lightest in its class, Cummins said. When paired with the Endurant transmission, Cummins offers the lightest powertrain in the industry.
As part of Cummins’ continued investment in advanced-diesel technologies, research is being conducted to further enhance turbocharger efficiencies and reduce emissions across the engine system. The Integrated System, a concept in development, packages new air handling and aftertreatment architectures closer together, which allows the turbocharger to work as efficiently as possible while still enabling effective thermal management. The system is being designed to help customers address future CO2 and NOx challenges.
