- Manufactured according to high standards, advanced and reliable
The K series was developed strictly according to SAIC’s GPDP standard process. With an integrated engine design, the marine engine comes with high-strength body and cylinder head, and forged steel crankshaft, and core components which are all supplied by well-known brands. It has an average engine overhaul period of over 20000 hours. - Strong power and high fuel efficiency
Designed with four valves, dual turbocharged structure, fully efficient air intake, and dual electronic control unit, etc., the marine engine are available with two types including high power engine with electronically controlled high pressure common rail, and low power engine with electronically controlled pump. With wide power and torque range, the engine is applicable to various working conditions with medium and heavy load requiring high torque. The minimum fuel consumption reaches 190g/kW•h, which saves more than 10% fuel than similar products in the market. - Strong adaptability and various configuration
Users choose different models according to different working conditions, among which 33W marine engine is suitable for high speed working conditions, and 38W is suitable for medium to low speed working conditions. Engine starting method, output interface, seawater pump with different flow rates, anti-corrosion cooling system, pre supply oil pump and other configurations are optional. - Comfortable and environmentally friendly, superior NVH (Noise, Vibration and Harshness)
The engine has a compact structure and attractive appearance. The NVH optimization design of the engine effectively reduces vibration and noise, improving the comfort of crew and passengers. - Long interval maintenance in a convenient manner
Due to modular design, extremely few faults will occur. The marine engine is designed with one cylinder and one head, making operation and maintenance more convenient.
