High Reliability and Strong Base

The SDEC SC4H marine engine provides steady and reliable power for a wide range of vessels. It uses a high-strength alloy cast-iron block, forged crankshaft, one-piece cylinder head, and rear gear housing. These durable parts make the engine strong and stable. In addition, it can run over 20,000 hours before a major overhaul. Therefore, operators can rely on the engine for long-term use and heavy tasks without worrying about breakdowns.

Strong Power and Low Fuel Use

The SC4H features a four-valve design and high fuel injection pressure, which improves airflow and fuel burning. As a result, the engine works efficiently, produces cleaner exhaust, and saves fuel. Moreover, it has high power density and extra power reserve, which allows fast acceleration when needed. Meanwhile, the fuel curve stays flat in normal working ranges, helping reduce fuel consumption and daily operating costs.

Compact Design and Low Noise

The SC4H has a modular and compact design that fits easily into small engine rooms. It is lightweight and takes up less space. In addition, it uses low-noise gears and a vibration-reducing main bearing support. Therefore, the engine runs quietly and produces less vibration, giving crew members a more comfortable and safer working environment.

Flexible Options and Wide Adaptability

The SC4H provides many optional configurations, including starting methods, output interfaces, exhaust pipes, and oil-filling points. Moreover, it performs well in various environments and can start in temperatures as low as –15°C. Because of this flexibility, the engine can handle different marine tasks and adapt to changing conditions at sea.

Easy Maintenance and High Uptime

The SC4H uses integrated components and has fewer wear parts, which lowers the risk of failures. The anti-wear valve system and fracture-split connecting rods extend service life. In addition, maintenance is simple and fast. As a result, the engine provides high uptime, reduces service costs, and ensures smooth operation for vessels over long periods.
