High-Power 6-Cylinder Turbocharged Diesel Engine Series – CM6D28G / CM6D30G for Industrial and Heavy-Duty Applications
The CM6D28G and CM6D30G series represent a new generation of high-performance, four-stroke, water-cooled Diesel Engines engineered for reliability, efficiency, and adaptability in demanding environments. Designed with international standards in mind, these engines feature a single overhead camshaft, inline six-cylinder configuration, and an advanced Bosch high-pressure common rail Fuel system delivering up to 1600 bar pressure—enabling precise multiple injection strategies that significantly improve fuel economy while reducing combustion noise. With B10 life exceeding 30,000 hours, they are ideal for long-term industrial use where uptime and durability matter most.
Engineered specifically for global markets outside China, including regions with variable fuel quality, the CM6D series incorporates a two-stage fuel filtration system to protect critical components like the fuel pump and injectors from contamination—a key differentiator for operators in developing or remote areas. The modular design minimizes part count, enhances serviceability, and ensures faster maintenance cycles without compromising structural integrity. A rear-mounted gear chamber equipped with helical gears provides smooth meshing action, quieter operation, and extended mechanical life—especially beneficial in noise-sensitive applications such as marine propulsion or generator sets.
These diesel engines are rigorously tested under extreme conditions: high-temperature environments, plateau altitudes up to 4700 meters, and mountainous terrain. This ensures consistent performance even when operating at elevated elevations, making them suitable for mining, construction, agriculture, and off-grid power generation across diverse climates—from arid deserts to alpine zones. Their emission compliance with GB20891 China Phase III standard demonstrates advanced combustion control technology that meets strict environmental regulations globally, aligning with evolving sustainability goals.
Key specifications include a range of rated outputs from 316 kW to 390 kW, with maximum torque values reaching 2400 Nm at speeds between 1000–1500 rpm, ensuring excellent low-end pulling power for heavy-load operations. Displacement options vary from 11.8L to 12.8L depending on model variants, offering flexibility for various vehicle and machinery platforms. Fuel consumption remains impressively efficient, staying below 194 g/kW·h at full load, which translates into reduced operational costs over time. Noise levels remain under 97 dB(A), contributing to operator comfort and regulatory compliance in urban or residential settings.
Whether powering large-scale agricultural equipment, industrial generators, marine vessels, or mining trucks, the CM6D28G/CM6D30G series delivers robust performance backed by intelligent diagnostics. Integrated control systems support real-time fault pre-diagnosis, remote monitoring, and secure lockout functions—an essential advantage for fleet managers seeking predictive maintenance capabilities. These features not only enhance safety but also reduce unplanned downtime through proactive intervention.
Users consistently praise the engine’s resilience in harsh conditions, noting minimal wear after thousands of hours of continuous operation. Operators appreciate the intuitive interface and reliable communication between engine and control units, simplifying troubleshooting and minimizing reliance on technical support. Maintenance intervals are extended due to the durable internal components and effective filtration strategy, further lowering total cost of ownership.
Frequently asked questions often center around altitude tolerance—these engines maintain full power output up to 2000 meters above sea level and allow for controlled derating up to 4700 meters, eliminating the need for complex adjustments during high-elevation deployments. Another common inquiry involves compatibility with aftermarket modifications; while OEM parts are recommended for optimal longevity, many users successfully integrate third-party sensors and controllers thanks to the open architecture of the electronic control unit (ECU). Finally, concerns about fuel quality are addressed through the dual-stage filter setup, which extends injector life and prevents premature failure—even when using fuels with higher sulfur content than typically found in developed nations.
