The engine adopts an inline 6-cylinder design and is equipped with an 11.8L large displacement core structure, with a maximum output power of 353kW and support for stable output at 1800rpm. The power transmission is smooth and long-lasting, and it is equipped with electronic high-pressure common rail fuel injection technology, which has the advantages of low energy consumption and environmental protection. It can easily meet the needs of various ships, whether it is heavy-duty transportation of merchant ships, smooth navigation of yachts, or continuous power supply of marine generator sets, it can provide stable and reliable power support. As a brand new spot model product, it can achieve fast delivery without long waiting times, significantly shorten the project landing cycle, and improve operational efficiency. At the same time, the engine structure has been strictly optimized, adopting advanced designs such as integral cylinder head and water-cooled wet cylinder liner. After 70000 hours of bench durability testing, it can effectively adapt to complex marine environments with high salt spray and strong turbulence, and has excellent durability, balanced power performance and operational stability. It also has CCS certificate and IMO emission certificate, fully meeting the needs of various marine scenarios such as commercial, leisure, and emergency power supply, demonstrating the technical strength and manufacturing level of Hualing Automobile in the field of marine power.

1. Strong power and wide adaptability: adopting an inline 6-cylinder design and an 11.8L large displacement core structure, the maximum output power can reach 353kW, supporting stable output at 1800rpm, and stable and long-lasting power transmission. Combined with electronic high-pressure common rail fuel injection technology, it has the advantages of low energy consumption and environmental protection, and can fully meet various ship power needs such as heavy loading of merchant ships, yacht navigation, and power supply of marine generator sets.
2. Spot delivery, efficient and convenient: Adopting a new spot delivery model, it can achieve fast delivery without long waiting times, significantly shorten the project landing cycle, effectively improve user operational efficiency, and solve the pain point of long delivery cycles for traditional engines.
3. Weather resistant, durable, stable and reliable: The structure has been strictly optimized and advanced designs such as integral cylinder head and water-cooled wet cylinder liner have been adopted. After 70000 hours of bench durability testing, it can effectively adapt to complex marine environments with high salt spray and strong turbulence, and has excellent durability and operational stability, ensuring long-term stable operation.
4. Compliant adaptation and guaranteed quality: With CCS certificate and IMO emission certificate, it fully meets the needs of various ship scenarios such as commercial, leisure, and emergency power supply. With stable and reliable comprehensive performance, it has become the preferred power equipment for commercial ships, yachts, and marine generator sets, demonstrating the excellent manufacturing level of Hualing Automobile.
(The person in charge of a merchant shipping company in Southeast Asia): “Our fleet travels to and from offshore routes for a long time, and we have extremely high requirements for the stability and power of marine engines. The CAMC marine engine has a strong 353kW power and a stable output of 1800rpm, which can fully meet the heavy load transportation needs of merchant ships. Moreover, the spot delivery mode allows us to avoid long waiting times and greatly shortens the resumption cycle after ship maintenance. What's even more surprising is that it can adapt well to high salt spray environments in the ocean, with an extremely low failure rate and durability beyond expectations. It has become the preferred power equipment for our fleet.”
(Purchasing Manager of a yacht manufacturing company in Europe): “Our yachts have strict requirements for power stability and environmental compliance. CAMC marine engines not only ensure smooth power transmission and comfortable yacht navigation, but also have IMO emission certificates, fully complying with European environmental standards. Its weather resistant and durable characteristics can also adapt to the complex environment of different sea areas, coupled with convenient spot delivery, effectively improving our production and delivery efficiency. We will continue to purchase in bulk in the future.”
CAMC International is a benchmark 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).
