The Yuchai YC16VC Marine Main Engine is a V-type marine diesel engine developed from the mature and proven 16VC platform. Yuchai designed this engine for inland waterway vessels and marine fishing boats operating under demanding conditions. By integrating advanced diesel engine technologies from Germany, the United States, and Japan, and by following modern European engine development processes, the YC16VC offers stable performance, strong reliability, and excellent adaptability. As a result, it serves as an ideal propulsion solution for a wide range of commercial marine applications.

Energy Saving and Environmental Protection

The YC16VC adopts a new-generation electronically controlled unit pump fuel system to improve fuel efficiency. In addition, the engine combines advanced design concepts with high- and low-temperature water cooling technology. It also features turbocharging with intercooling and a four-valve cylinder head design. Therefore, this marine diesel engine meets IMO Tier II emission requirements while reducing fuel consumption and exhaust emissions under various operating conditions.

Compact Structure

The YC16VC features a compact overall layout with reduced size and optimized weight. As a result, installation becomes easier and maintenance more convenient, even in engine rooms with limited space. Furthermore, the camshaft integrates fuel injection and valve actuation into a single structure, which improves space utilization and ensures a compact engine configuration.

High Reliability

Yuchai equips the engine with a high-strength cylinder block, a forged alloy steel crankshaft, and alloy steel connecting rods. Consequently, this robust design reduces impact loads on the main bearings and enhances durability. In addition, it ensures reliable long-term operation during continuous high-load marine service.

Strong Load Acceptance Capability

By combining electronically controlled unit pump technology with an advanced turbocharging system, the YC16VC responds quickly to load changes and maintains stable speed control. Moreover, it delivers strong load acceptance, which is essential for vessels operating under variable marine conditions.

Easy Maintenance

Yuchai arranges the intake manifolds on both sides of the engine to improve service accessibility. Meanwhile, the one-cylinder-one-head design uses a mature and proven cylinder head platform, which simplifies inspection and routine maintenance. In addition, a proprietary turning gear mechanism further improves maintenance efficiency and reduces service time.
