On September 23rd, at the China (Beijing) International Construction Machinery, Building Materials Machinery and Mining Machinery Exhibition (BICES 2025), Cummins unveiled a new low-carbon power solution for the off-road market. This solution includes a next-generation excavator hydraulic system with an intelligent control system, a 3.9L-15L hybrid power system, and a 19L methanol industrial engine. The solution empowers the construction and mining machinery sectors with technological innovation, while also showcasing the achievements of domestically producing a full range of mining power products, contributing to the development of a sustainable ecosystem for the industry.

 Fifty Years of Partnership

Empowering China's Construction Machinery Industry

 From introducing its first high-horsepower engine to China in 1975 to today's comprehensive and diverse power solutions for the industry, Cummins has consistently leveraged its global technological strength to deeply integrate with the Chinese market. Over the past 50 years, from traditional fuel-powered engines to low-carbon and even zero-carbon power systems, and from single-application scenarios to diversified power solutions, Cummins has consistently been at the forefront of technology, providing reliable and green power support for the Chinese construction machinery industry.

Diverse Power Sources

Together Toward a Zero-Carbon Future

Cummins' new low-carbon power solutions for the off-road market provide the construction machinery industry with diverse low-carbon power options.

Intelligent Hybrid System

Furthermore, the new generation of excavator hydraulics is equipped with an intelligent control system, designed specifically for the dynamic power needs of excavators. Through active interaction and coordinated control between the engine and hydraulic system, it achieves over 10% improvement in energy efficiency.

New Methanol Power

Cummins has released the industrial version of its 19L methanol engine, developed and manufactured by Chongqing Cummins. This represents a major breakthrough in displacement and fuel options for its multi-fuel engine platform. Utilizing multi-point inlet injection and spark ignition technology, this engine reduces CO2 emissions by 18% when using conventional methanol compared to a diesel engine, while using green methanol can achieve zero carbon emissions.

This engine boasts 500kW of continuous power and is precisely adapted for wide-body mining trucks (135-160 tonnes) and large excavators (130-160 tonnes). It can also be flexibly expanded to various applications, including power generation and marine applications, offering broad adaptability. The product offers outstanding performance advantages: First, it features innovative cold-start technology, enabling stable operation in extreme environments ranging from -35°C to 50°C. Second, it boasts excellent altitude adaptability, maintaining full torque output at altitudes up to 3,000 meters. Third, its oil filter maintenance interval is up to 500 hours, significantly reducing maintenance costs. Fourth, it offers integrated range-extended powertrain services, providing a comprehensive powertrain solution. Fifth, it shares the same high-reliability components as the 19L series, offering high commonality and easy maintenance. Newly designed key components are also alcohol-resistant and corrosion-resistant, further enhancing operational stability.

Electric Drive Technology

 In the hybrid power sector, Cummins' electric drive business demonstrates strong technical capabilities, providing users with a complete range-extended and plug-in hybrid powertrain, encompassing the range extender, all-in-one controller, drive motor, and electric drive axle. This provides a solid foundation for efficient equipment operation.

 Leveraging the unique advantages of deep powertrain integration, Cummins' electric drive technology can precisely optimize the hybrid system's energy consumption in real time based on actual operating conditions, while also optimizing power output, ensuring outstanding performance in diverse operating scenarios. Furthermore, in terms of pure electric technology, Cummins has completed the development of two major platforms: central drive and electric drive axle, which comprehensively cover various construction machinery applications. This platform can also be flexibly combined with single-motor controllers or all-in-one controllers, allowing for in-depth customization based on specific customer needs. Notably, all core components support 800V systems, providing customers with even greater power performance and further meeting the industry's demand for efficient and green power.

 Off-road Components

 Cummins customizes core components for off-road applications, balancing diverse operational requirements with efficient and stable equipment operation. The emission treatment system, available for Euro V and National IV non-road heavy-duty engines, is integrated with the engine and works with the ECM electronic control to optimize performance, reduce fuel and urea consumption, and features ultra-long cleaning range, non-stop soot cleaning, and sensorless regeneration. Rigorously tested to ensure reliability. Other innovative features include turbochargers and fuel systems: methanol turbochargers are corrosion-resistant and suitable for low-carbon applications, while high-horsepower turbochargers expand the application range of construction machinery. High-flow injectors provide precise fuel delivery and improve efficiency, while high-horsepower oil pumps enhance adaptability and durability. High-power braking technology improves braking safety and reduces wear in mining trucks, while brake clearance adjustment-free technology improves efficiency and reduces costs.

Deepening our presence in China

 Creating a Chinese Mining Power Solution

 Cummins is deepening and upgrading its localization strategy, providing customized services tailored to Chinese needs. It has achieved localization of its entire mining power system, covering displacements from 19L to 60L and horsepower from 600 to 3000hp, meeting multiple emission standards.

 In collaboration with OEMs, customized development tailored to mining environments has reduced fuel consumption of localized high-horsepower engines by 10%. Upgraded filter elements and filtration systems, along with long-life split-flow centrifugal filters, extend maintenance intervals to 1000 hours. Leveraging its Chongqing base, Cummins has achieved a closed-loop system for R&D, production, sales, and service of high-horsepower products in China, adapting them to local operating conditions, reducing costs, and improving efficiency. Cummins also leverages its global service network and uses digital tools to provide integrated high-horsepower services.

 Cummins engines from 3.9L to 15L are now hybrid-powered, including extended-range, P1, and P2+P2.5 configurations. These offer differentiated architectures for applications such as excavators, loaders, mining trucks, rotary drills, and reach stackers. This deeply integrated "engine + motor + battery" system improves system fuel economy by 10%-30% and extends battery life by over 20%, providing continuous, efficient, and low-emission power options for demanding applications such as high-altitude, cold regions, and heavy loads.
