Cummins Integrated Powertrain: Enhancing Fuel Efficiency and Performance

The Cummins 15L National VI Engine, with a mass production thermal efficiency reaching up to 48%, incorporates advanced technologies such as high-efficiency turbochargers, ultra-high pressure common rail fuel injection systems, U-shaped low back-pressure after-treatment structures, intelligent thermal management, and Down Speed optimization of the powertrain. These innovations significantly improve fuel economy by 5% to 12%. At the same speed, fuel consumption is reduced, and at the same fuel consumption, vehicle speed is increased.

Recently, this engine was awarded the "Discover Trust 2025 - Cross-border Logistics Efficient Engine Trusted by Users" for its outstanding performance in long-distance trunk transportation and complex road conditions, ensuring stable and economical fuel consumption levels.

WinDrive AMT Transmission
Equipped with advanced intelligent electronic control technology, the WinDrive AMT transmission integrates GearLogic intelligent control features. It automatically selects the appropriate gear and performs flexible shifting based on factors such as road slope, vehicle weight, engine torque, and throttle opening, assisting drivers in optimizing performance. Key features include intelligent neutral coasting, predictive shifting, and predictive cruise control, all of which contribute significantly to fuel savings. Additionally, the transmission offers a wide speed ratio range and overdrive configuration, enabling lower engine cruise speeds and further enhancing fuel efficiency.

Cummins Emission Control System
Utilizing efficient SCR technology, the Cummins emission control system ensures precise urea injection. Combined with advanced mixer technology, it achieves thorough reactions, maintaining the engine's fuel efficiency while meeting stringent emission standards.

Tailored for the Chinese market, the Cummins 15L Integrated Powertrain delivers a 76% increase in acceleration potential and a 20% improvement in climbing capability. The overall efficiency of the powertrain has been significantly enhanced. With a powerful output and a broad peak torque range, it excels in various working conditions, providing strong climbing and acceleration capabilities. Based on specific application scenarios, the powertrain selection and shifting strategy are optimized to achieve a transmission efficiency of up to 99.8%, ensuring the engine operates within its most economical range to balance power and fuel consumption, thereby maximizing fuel savings for users.
