New Standard and Advanced Reliability

The SDEC SC33W marine engine is developed under the strict SAIC GPDP standards. It features an integrated design, high-strength block and cylinder head, and a forged crankshaft. With these durable parts, the engine achieves an average overhaul life of over 20,000 hours. Therefore, operators can rely on long-term, stable performance even under heavy workloads.

Strong Power and High Efficiency

The SC33W uses a four-valve, twin-turbo design that ensures efficient and full air intake. Its electronic unit pump works with a matched ECU and injectors to improve combustion and reduce emissions. As a result, the engine runs smoothly, saves fuel, and delivers strong power on demand. Maximum torque reaches 6400 N·m, while power increases by 10%. In normal working ranges, the engine maintains low fuel consumption and high torque, with a minimum fuel use of 190 g/kWh.

Flexible Options and Wide Adaptability

Users can select configurations based on vessel needs. The 33W engine suits high-speed operations, while the 38W model works better for medium- to low-speed tasks. Optional features include various starting methods, power output interfaces, seawater pumps with different flows, anti-corrosion cooling systems, and electric pre-fuel pumps. These options ensure the engine adapts to diverse marine conditions.

Comfort, Environmental Performance, and Low NVH

The SC33W has a compact, visually appealing design with optimized NVH. It reduces vibration and noise, improving comfort for crew and passengers. In addition, the engine meets modern environmental requirements, providing cleaner operation and smoother performance.

Easy Maintenance and Long Service Intervals

The engine’s modular design reduces potential faults. Each cylinder has a single cylinder head, making maintenance faster and simpler. Moreover, the extensive service network across the country ensures quick support. As a result, operators save time, reduce maintenance costs, and enjoy high uptime.
