The Yuchai YC6MK Auxiliary Engine for Marine Emergency Gensets is designed to provide stable and dependable emergency power for marine applications. It supports emergency generator sets on inland and near-shore vessels, where fast start-up and continuous reliability are critical. By combining proven mechanical strength with advanced electronic control, this engine ensures power availability when it matters most. Moreover, its compact design and efficient operation make installation and long-term use easier for ship operators.

High Reliability

First, the engine follows strict mechanical development and validation standards. During development, it passes multiple tests, including thermal shock tests, high- and low-temperature tests, and crankshaft fatigue tests. In addition, European development methods support reliability improvement across the entire design process. As a result, the major overhaul interval exceeds 12,000 hours, ensuring long service life and stable performance for emergency genset operation.

Fuel Efficient and Cost Effective

The engine adopts Yuchai’s advanced electronic control technology. Therefore, it allows precise control of fuel quantity and injection timing. Combustion remains stable and efficient, which reduces fuel consumption and lowers operating costs. Furthermore, four-valve technology increases intake and exhaust airflow, while the centrally positioned injector improves fuel atomization. Consequently, combustion becomes more complete and fuel efficiency improves during both standby and load operation.

Safe and Stable Operation

To enhance safety, the engine is equipped with digital local and remote monitoring instruments. These systems allow real-time monitoring and protection of engine operation. At the same time, the integrated cast iron freshwater-cooled exhaust manifold reduces engine room temperature. Thus, overall operating safety improves, and the onboard environment becomes more comfortable during emergency power operation.

Low Noise and Smooth Running

In addition, the optimized structure and combustion control help reduce vibration and noise. Smooth operation protects connected generator equipment and supports reliable power output. As a result, the engine maintains stable performance even during sudden load changes, which is essential for marine emergency gensets.

Overall, the Yuchai YC6MK Auxiliary Engine for Marine Emergency Gensets offers a balanced solution that combines reliability, efficiency, safety, and ease of operation, making it a trusted choice for marine emergency power systems.
