With the core advantages of lightweight design, ultra quiet operation, and stable high-power output, it has become the preferred equipment for various types of ship power supply, providing reliable and powerful power support for ship navigation, communication, and various auxiliary equipment, demonstrating CAMC's technological accumulation in the field of marine power. This engine is made of advanced lightweight materials, which makes it easier to transport, install, and operate compared to traditional bulky models, and is in line with the spatial layout characteristics of ship engine rooms; Equipped with an innovative electric exhaust system, using electric static hydraulic actuation technology to achieve intelligent adjustment of exhaust valve timing and lift, integrating the advantages of high efficiency and energy saving. At the same time, it has been specially optimized to achieve ultra quiet operation. Through vibration isolation, sound insulation and noise reduction design, the operating noise is greatly reduced, avoiding interference with crew life and ship equipment operation, and meeting the standards of ship quiet operation. The engine structure is compact and neat, and can be installed neatly in the internal compartments of the ship without occupying too much space. The rated power covers 164-321kW, and the rated speed is stable at 1500-1800rpm. The power output is strong and continuously stable, suitable for the power needs of ships of different tonnages. Based on the four stroke cycle working principle, it achieves efficient fuel conversion, balancing power performance and economy. As a brand new product, it has undergone strict and comprehensive factory testing, and all performance indicators have reached the industry's high standards. After installation, it can provide stable power for ships without additional debugging. With mature manufacturing technology, it is suitable for complex operating environments such as high humidity and high salt spray on ships, and has outstanding durability, laying a solid foundation for long-term stable navigation of ships.

"Hanma power" engine is independently developed by the company and has completely independent intellectual property rights. At present, it has obtained 43 inventior patents, 135 utility model patents and 25 appearance patents.
The company has invested and built an engine automation production base with international advanced level, with a design capacity of 50000 units/ year. The company has four major production workshops: machining, final assembly, hot testand coating.
Equipped with international and domestic top processing, assemibly,testing, and coating equipment. The company practices the concept of green manufacturing and uses advanced network information technology to build an engine industry, and realizes the whole process automation flexibility, informatization and intellligent manufacturing of engine products.
"Hanma power" was officially put on the market in 2013. With its signficant advantages of energy conservation, environmental protection safety and relablity, it is welcome by users and exported to more than 30 countries and reaions in Southeast Asia, South America, Middle ast Ainca and other places, so far the production and saes have exceded 80000 units. It goes hand in hand in the two fields of road engine and off road engine, and ranks among the mainstream engine brands in China.
1. The person in charge of the operation of a certain European cargo ship: “Our cargo ship has high requirements for the convenience and quietness of the engine. The CAMC four stroke electric exhaust marine engine uses lightweight materials, making installation and operation very worry free. The ultra quiet operation hardly affects the rest of the crew. The rated power of 164-321kW fully meets our navigation needs, with stable operation at 1500-1800rpm. It has passed the factory test and is directly put into use after installation. It is suitable for high humidity environments at sea and has been running without any faults, making it very reliable.”
2. Purchasing Manager of a sightseeing boat in Southeast Asia: “Sightseeing boats have strict requirements for noise control, and the ultra quiet design of this engine perfectly meets our needs. At the same time, the lightweight and compact structure does not occupy too much cabin space. The power output is stable, and the rated speed and power are suitable for our sightseeing boat navigation needs. It is installed and used immediately, saving the trouble of debugging and convenient maintenance in the later stage, effectively improving the operating experience of sightseeing boats. It has been purchased and put into use in bulk.”
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).
