Product introduction:

Sc25k series marine engine is a new generation of medium and high speed marine diesel engine, which has accumulated many years of experience in ship engine design and development of Shangchai company, and has absorbed excellent and mature technologies at home and abroad.

This series of products fully consider the characteristics of marine main engine, such as multi-purpose, multi working conditions, high reliability and high economic requirements, which is greatly improved compared with similar products in the market. With beautiful appearance, compact structure, large speed range, strong power performance, large low-speed torque reserve, low oil and diesel consumption, easy to use, it is the ideal main engine power for new generation of transport ships, fishing boats, engineering ships and other ships, as well as 350-550kw marine generator set market.


Product features:

1. Gantry body, rear gear chamber, good rigidity, low vibration and low noise;

2. Four valve structure, one cylinder and one cover, easy to use and maintain;

3. Integrally forging high strength crankshaft and connecting rod with good reliability;

4. Double supercharger intake system, more efficient and full intake, compact structure and beautiful appearance;

5. The torque reserve is large, which can meet the requirements of medium and heavy loads for medium and high speed torque, and the reserve is 20-30%;

6. Low cost of use: lower fuel consumption and oil consumption rate, greatly reducing the use cost of customers.

7. Safe and reliable: after more than 3000 hours of durability test, the main parts are in good condition.
