Proven and Reliable with Better Economy

The SDEC SC15G auxiliary engine is built on a modular design that increases strength and stability. It uses a reinforced block, an integrated cylinder head, a forged steel crankshaft, and fracture-split connecting rods. These key parts improve durability and help the engine work well under long and heavy use. At the same time, all sealing gaskets are upgraded to reduce leaks and improve long-term reliability. The engine also uses an electronic unit pump system that offers clean and efficient combustion, and it easily meets China Stage II marine emission standards.

Strong Power with Large Torque

The SC15G features a large displacement that brings strong power and a wide power reserve. Its fuel curve stays flat across common working ranges, so the engine keeps stable fuel use in daily operations. Moreover, it delivers high torque at low speeds, which improves load response and overall efficiency. When compared with traditional mechanical pump engines, the electronic system helps save more than 5% in fuel consumption, which lowers operating costs for ship owners.

High Load Capacity with Broad Environmental Adaptability

This engine handles sudden load changes with quick acceleration, so it supports many different duty conditions. In addition, it performs well even when users operate with lower-grade engine oil, fuel, or coolant. Because of this, the SC15G fits harsh environments and demanding work sites where stability matters.

Easy Maintenance with Higher Uptime

Most parts remain interchangeable with earlier models, which improves serviceability and reduces maintenance time. The long service interval and well-tested reliability help the engine maintain high uptime throughout the year. Since the SC15G has a large population in the market, spare parts are widely available. As a result, the cost of maintenance stays low and daily operation becomes easier for users.
