The CM6D28C series diesel engine is a high-performance power solution designed specifically for heavy-duty conditions, including two models: C6D28C.353.20 (main engine) and CM6D28C.350.20 (auxiliary engine). Adopting six cylinder inline, water-cooled, and direct injection technology, the maximum power reaches 353kW (480Ps) and the maximum speed is 1800r/min. It can maintain stable output even in harsh environments.
Its reinforced crankshaft and cylinder structure have passed a 100000 hour durability test, and the B10 lifespan has exceeded 30000 hours, making it suitable for various scenarios such as construction machinery and generator sets. The intelligent electronic control high-pressure common rail system has achieved an 8% reduction in fuel consumption compared to its peers, and emissions meet the National VI/Euro VI standards. Modular design simplifies maintenance processes and has been widely used in heavy industries such as mining and ports, becoming a benchmark choice for high reliability power.

Super powerful performance
Adopting six cylinder inline high-pressure common rail technology, the maximum power is 353kW (480Ps), the maximum speed is 1800r/min, the torque fluctuation under heavy load conditions is ≤ 3%, and the power output stability is industry-leading.
Durable and reliable military grade
Strengthening the design of the crankshaft and alloy cylinder block, after 100000 hours of bench testing, the B10 has a lifespan of 30000 hours and a 40% reduction in failure rate compared to its peers.
Intelligent, efficient and energy-saving
The electronic control injection system, combined with variable cross-section turbocharging, reduces fuel consumption by 8%, meets the National VI/Euro VI standards for emissions, and saves over 15% in annual operating costs.
Full scene adaptability
Modular design supports rapid maintenance and wide temperature range operation from -30 ℃ to 50 ℃, adapting to the needs of various fields such as engineering machinery and generator sets.
Technical Director Evaluation of Middle Eastern Power Plants
“Our CM6D28C auxiliary unit has been running continuously for 2 years without major repairs at a high temperature of 50 ℃ in Dubai, and its 353kW power output stability far exceeds that of its European and American competitors. The intelligent electronic control system reduces fuel consumption by 10% compared to expectations, but it is recommended to enhance the automatic alarm function of the air filter in dusty environments.”
Feedback from South American Mining Group
“The 15 mainframe versions of the Chilean copper mine have withstood the test of oxygen deficient environment at an altitude of 4000 meters, with a full load speed retention rate of 98% at 1800r/min. Modular design reduces maintenance time by 30%, and it is recommended to shorten the oil change cycle under high dust conditions.”
CAMC International is a leading enterprise in China's heavy vehicle manufacturing industry. As a key national supported research and development production base for heavy vehicles and components, the company has maintained a leading position in the industry since its establishment in the 1970s. With a complete layout of the entire industry chain, CAMC has become the only truck manufacturer in China with the ability to independently produce core components such as engines, transmissions, axles, chassis, and cab, achieving full process autonomy and controllability from key components to the entire vehicle.
The company relies on the research and development strength of the national enterprise technology center, and its products cover a full range of commercial vehicles such as heavy-duty trucks, engineering dump trucks, and special transport vehicles, which are widely used in key areas of the national economy such as infrastructure, mining, and logistics. Through continuous technological innovation and intelligent manufacturing upgrading, CAMC not only maintains a leading position in the domestic market, but also sells its products to more than 80 countries and regions around the world, especially in the markets along the "the Belt and Road". As a representative enterprise of high-end equipment manufacturing in China, the company is actively promoting the application of new energy and intelligent technology in the commercial vehicle field, leading the industry to transform and upgrade towards green and low-carbon direction.
1.Q: What maintenance frequency is recommended for this engine in marine use?
A: For standard inland/coastal operations, we recommend routine oil/filter changes every 200 operating hours, and a comprehensive inspection (cooling system, supercharger) every 800 operating hours. Adjustments may be needed for extreme working conditions (e.g., frequent heavy loads).
2.Q: Can this engine be retrofitted into older vessels?
A: Yes—its compact inboard layout and modular design are compatible with most existing engine room spaces for older vessels. We suggest confirming the installation dimensions and interface specifications with our technical team before retrofitting.
3.Q: How does the automatic supercharging system perform in low-load conditions?
A: The system automatically reduces boost pressure in low-load scenarios (e.g., light cargo, calm waters) to optimize fuel efficiency while maintaining smooth, stable operation—avoiding unnecessary power waste.
4.Q: Is the engine compatible with low-sulfur diesel (required in emission-controlled areas)?
A: Absolutely. It is designed to run on low-sulfur marine diesel, meeting emission standards for most global coastal emission-controlled zones (ECAs).
