With advanced structural design and reliable performance, it has become a benchmark for efficient power in the maritime field, and can be widely applied to inland and coastal small and medium-sized ships and various offshore operation scenarios, providing efficient, reliable, and durable core power support for ship navigation and equipment operation, while meeting relevant marine environmental protection and safety standards, and adapting to the offshore operation needs of multiple regions around the world. The engine adopts an inline six cylinder layout, equipped with a single overhead camshaft, integrated cylinder head, symmetrical gantry cylinder block, four valve configuration, rear gear chamber and other core structures. Combined with the four stroke operation mode, the structural design is scientifically reasonable, effectively optimizing the intake and exhaust efficiency and combustion efficiency, greatly improving operational stability and durability. Its outstanding B10 life can fully meet the long-term continuous operation needs of ships. The engine has a displacement of 12.8L, a rated power of 408HP, and a maximum speed of 1800r/min. The power output is strong and stable, relying on advanced structural design and electronic fuel injection technology to perfectly balance power performance and fuel economy. The lowest fuel consumption rate is better than similar products, balancing high efficiency and energy saving. At the same time, it adopts a compact structural design, with a small volume and easy installation, which can flexibly adapt to the installation space requirements of various small and medium-sized ships. With its all-round core advantages, it has become the preferred equipment for small and medium-sized ship power in the maritime field.

1. Head of Overseas Ship Operation Enterprise: “Our fleet mainly engages in coastal small and medium-sized ship transportation. The power performance of the CAMC 12.8L 408HP marine engine is excellent. The 408HP power can fully meet the heavy load navigation needs of the ship, and the fuel consumption is lower than the similar engines we have used before. The compact structure also perfectly fits our ship installation space, and there have been almost no failures since operation. The reliability far exceeds expectations, making it the core power choice of our fleet.”
2. Overseas maritime equipment purchaser: “As a company specializing in maritime equipment procurement, we have compared multiple marine engines. This engine has a scientifically designed structure, easy installation, and outstanding B10 lifespan, which can meet the long-term continuous operation needs of ships. At the same time, it meets our local marine environmental protection and safety standards. After bulk procurement, we have received good feedback and will continue to cooperate in the future.”

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).
