The Yuchai YC6TDN Marine Gas Auxiliary Engine is designed to meet the growing demand for clean, efficient, and reliable auxiliary power in modern vessels. By combining proven engine architecture with advanced gas combustion and electronic control technology, it provides stable power output, low emissions, and excellent operating economy. As a result, it is well suited for auxiliary power supply on various gas-fueled and dual-fuel marine platforms.

Clean and Efficient Gas Power

The engine adopts advanced gas combustion technology to achieve stable and efficient energy utilization. Precise control of gas-air mixing ensures complete combustion, which reduces fuel consumption and minimizes exhaust emissions. Therefore, the engine supports cleaner operation while maintaining dependable auxiliary power performance.

High Reliability

Built on a mature engine platform, the YC6TDN uses a high-strength alloy cast iron cylinder block and cylinder head to ensure structural durability. In addition, a forged steel crankshaft and reinforced key components improve resistance to fatigue and wear. These features allow the engine to operate reliably under long-hour auxiliary duty cycles.

Stable Auxiliary Performance

Advanced electronic control systems manage ignition timing, gas supply, and load response with high accuracy. As a result, the engine delivers smooth power output, fast response to load changes, and stable operation, which is essential for marine auxiliary power systems and onboard electrical equipment.

Low Operating Cost

Compared with traditional diesel auxiliary engines, gas fuel helps reduce fuel costs while extending maintenance intervals. Moreover, optimized combustion reduces carbon deposits and component wear. Consequently, overall operating and maintenance costs remain lower throughout the service life.

Safe and Environmentally Friendly Operation

Multiple safety protection strategies are integrated into the control system to ensure safe gas operation. At the same time, low emissions help the engine comply with increasingly strict marine environmental requirements. This makes the YC6TDN a practical and forward-looking choice for modern marine auxiliary power solutions.
