Core Product Portfolio: Comprehensive Power Solutions for All Scenarios

1. Traditional Power Core: Efficient and Reliable Engines & Generator Sets

🔵Engine Series: Covering a full displacement range of 2.5L-95L, offering multi-fuel options including diesel, natural gas, hydrogen, and methanol, suitable for both on-highway and off-highway scenarios. On-highway engines are widely used in medium/heavy-duty trucks, buses, and light commercial vehicles; off-highway engines serve construction machinery, agricultural equipment, mining machinery, marine vessels, oil & gas fields, and railways. Renowned for exceptional power performance, fuel efficiency, and reliability, these engines have taken the lead in advancing National VII/Non-road Stage V emission technology reserves, continuously meeting stringent global emission standards.​
🔵Generator Set Series: Providing 2.5kW-2700kW diesel/gas generator sets, paired with 0.6kVA-30,000kVA alternators and complete control systems. These solutions deliver emergency power supply, backup power, and primary power for data centers, hospitals, financial institutions, factories, remote mining areas, and other scenarios, ensuring uninterrupted power availability.

2. New Energy Breakthrough: Full-Industry-Chain Layout for Zero-Carbon Power​
Through Cummins Accelera™, the company's new energy brand, a full-chain zero-carbon solution covering "hydrogen production, storage, transportation, and application" has been established:

🔵High-Power Fuel Cell Systems: Boasting high power density, long service life, and lightweight design, suitable for buses, trucks, rail transit, marine vessels, and power generation scenarios;​
🔵Hydrogen Technology: Including water electrolysis hydrogen production equipment, 700Bar high-pressure hydrogen storage systems, hydrogen internal combustion engines, and core components (hydrogen injectors, air compressors, etc.), supporting hydrogen production coupled with renewable energy;

🔵Electric Drive Solutions: Comprising central drive motors, e-axles, and integrated power electronics, meeting electrification power demands;​
🔵Transitional Technologies: P1/P2/P4 hybrid architectures, microgrid integration, and energy storage technologies, achieving approximately 20% fuel savings to facilitate customers' smooth transition.

3. Key Components & System Integration​
Independently researching and manufacturing core components such as turbochargers, fuel systems, emission aftertreatment systems, transmissions, and braking systems, Cummins has built full power chain integration capabilities. The launch of Multi-Fuel Powertrain 3.0 realizes collaborative optimization of engines, aftertreatment systems, and transmissions through intelligent control technology, ensuring operation in the efficient range at all times. Leveraging digital twin and artificial intelligence technologies, the company provides customized R&D and real-time operating condition optimization services.

Technological Advantages: Innovation-Driven Sustainable Development Capabilities

🔵Dual-Track Strategy: Simultaneously advancing traditional power emission reduction and zero-carbon technology breakthroughs, investing over $1 billion annually in R&D, with more than 11,000 engineers and 50 global technology centers;​
🔵Localization Strength: Establishing 37 institutions and 26 manufacturing enterprises in China, localizing production for 19 engine series, and soon launching a 30-liter high-horsepower platform tailored for mining operating conditions;

🔵Significant Environmental Achievements: Through technological innovation, cumulative reduction of 55 million tons of greenhouse gas emissions, equivalent to saving 5.4 billion gallons of diesel, helping customers reduce costs while achieving carbon emission reduction goals.

Global Application Scenarios: Full-Scenario Coverage from Polar Regions to Urban Areas

Cummins power is present in various harsh environments worldwide: from plateau transportation on the "Roof of the World" to Antarctic research station construction, from urban logistics and express delivery to agricultural machinery in vast fields, from long-distance voyages of deep-sea vessels to stable power supply for data centers. It provides 24/7, full-condition reliable power support for truck drivers, mining operators, engineering constructors, power service providers, and other users.

Service Support: Global Network & Intelligent Assistance

🔵Global Service Network: Operating over 500 distribution and service outlets and more than 10,600 authorized dealers worldwide; in China, covering 18 provincial customer support centers and over 3,000 authorized dealers;​
