Product Overview
As a core power unit tailored for marine scenarios, CAMC’s 11.8L marine automatic supercharged diesel engine combines "high power + extreme reliability" to serve as the main propulsion system for inland river and coastal vessels. Featuring a 6-cylinder inline layout paired with automatic supercharging technology, it delivers robust, consistent power at a stable 1800rpm. Its closed water-cooling system is optimized for the long-duration, high-load demands of marine navigation—making it a top-tier choice for next-gen marine propulsion.

Product Advantages
Automatic Supercharging: Unmatched PowerThe built-in automatic supercharging system intelligently adjusts intake pressure based on the vessel’s load (e.g., against currents or heavy cargo) without manual intervention. The 11.8L large displacement + 6-cylinder design ensures sustained, strong power output in complex waters—eliminating the frustration of insufficient propulsion.
Water-Cooled Stability: Non-Stop DurabilityThe fully enclosed water-cooling system is upgraded for the marine environment (humidity, salt spray), efficiently regulating engine temperature even during continuous long-hour operation. This drastically reduces overheating risks, perfectly matching the long-endurance needs of marine navigation.
Marine-Specific Design: Seamless IntegrationThe "Inboard" mounting configuration fits seamlessly into standard vessel engine room layouts. Its compact dimensions (1780×986×1448mm) and modular structure simplify integration and post-sales maintenance, cutting down shipyard installation and debugging costs.
Brand-New Quality: Worry-Free ReliabilityDelivered in brand-new condition, this engine leverages CAMC’s proven diesel power expertise. Every component—from cylinder block materials to pipeline seals—undergoes marine environmental durability testing, withstanding vibration and salt corrosion to ensure safe, stable navigation.
Application Scenarios
Main propulsion for inland cargo vessels
Power system for coastal working ships (e.g., aquaculture vessels, engineering ships)
Main drive for small passenger ships and official vessels

Our Factory
CAMC is the national priority production and research development base of heavy trucks, special purpose heavy vehicles and spare parts, which is also the state mainly supports enterprise. CAMC was found in 1970s and we are the only truck enterprise in China which is capable of produing everything on our own including engine, gearbox, axles, chassis, cabin and so on. For years, CAMC has been doing good and professional work in commercial vehicles. Our product covers a huge scope in this field, like tractor truck, dump truck, concrete mixers, pump truck, cargo truck, garbage truck, crane truck, bulk cement truck, tank-carring truck, semitrailers and other special vehicles along with different driving forms such as 4X2, 6X2, 6X4, 8X4, 10X4. The emission standard covers a range from EURO 2 to EURO 6.
FAQ
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).
