The Yuchai YC16VCX Marine Auxiliary Engine is designed for marine generator sets in the 1600–2000 kW power range. Developed from the proven VC-series platform, this auxiliary engine integrates advanced diesel engine technologies from Germany, the United States, and Japan. By following modern European engine development processes, the Yuchai YC16VCX Marine Auxiliary Engine delivers stable performance, high efficiency, and strong adaptability for continuous marine power generation.

Energy Saving and Environmental Protection

The Yuchai YC16VCX Marine Auxiliary Engine adopts a new-generation electronically controlled unit pump system to improve fuel efficiency. In addition, it combines advanced design concepts with high- and low-temperature water cooling technology, turbocharging with intercooling, and a four-valve cylinder head design. As a result, the engine meets IMO Tier II emission requirements while reducing fuel consumption and exhaust emissions during long-term operation.

Compact Structure

This marine auxiliary engine features a compact structure with reduced size and optimized weight. Therefore, installation becomes easier and maintenance more convenient. Furthermore, the camshaft integrates fuel injection and valve actuation into one design, which improves space utilization and ensures a compact engine layout in generator rooms.

High Reliability

Yuchai equips the YC16VCX auxiliary engine with a high-strength cylinder block, a forged alloy steel crankshaft, and alloy steel connecting rods. Consequently, this robust structure reduces impact loads on the main bearings and enhances durability. The Yuchai YC16VCX Marine Auxiliary Engine ensures reliable operation under continuous high-load conditions.

Strong Load Acceptance Capability

By combining electronically controlled unit pump technology with an innovative four-turbocharger parallel configuration, the engine responds quickly to load changes. Moreover, it maintains stable speed control and delivers strong load acceptance, which is essential for marine auxiliary power systems.

Easy Maintenance

The intake manifolds are arranged on both sides of the engine to improve service accessibility. In addition, the one-cylinder-one-head design uses a mature cylinder head platform proven in long-term applications. A proprietary turning gear mechanism further simplifies maintenance and improves overall service efficiency.
