The Yuchai YC16VCX marine main engine is a new-generation V-type marine diesel engine developed from the proven YC16VC platform. Yuchai designed this engine specifically for inland waterway vessels and marine fishing boats. At the same time, the development team integrated advanced diesel engine technologies from Germany, the United States, and Japan. By following modern European engine development processes, the YC16VCX marine engine delivers high efficiency, strong reliability, and stable performance. Therefore, it provides an ideal power solution for various commercial vessels and fishing boats.

Energy Saving and Environmental Protection

The Yuchai YC16VCX marine diesel engine uses a new-generation electronically controlled unit pump fuel system to improve fuel efficiency. In addition, the engine applies advanced design concepts together with high- and low-temperature water cooling technology. It also features turbocharging with intercooling and a four-valve cylinder head design. As a result, the YC16VCX meets IMO Tier II emission requirements. Moreover, it reduces fuel consumption and exhaust emissions while maintaining stable operation under different marine working conditions.

Compact Structure

The YC16VCX marine main engine features a compact layout with reduced overall dimensions and lower weight. Therefore, shipbuilders can install the engine more easily, even in limited engine room space. Furthermore, the camshaft integrates fuel injection and valve actuation into one structure. This design improves space utilization and simplifies the overall engine layout.

High Reliability

Yuchai equips the YC16VCX marine 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. In addition, it enhances durability and ensures reliable operation during long-term, high-load marine service.

Strong Load Acceptance Capability

The YC16VCX combines electronically controlled unit pump technology with an innovative four-turbocharger parallel configuration. Therefore, the engine responds quickly to load changes. Moreover, it maintains stable speed control and delivers strong load acceptance, which is essential for marine propulsion under variable operating 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 maintenance. In addition, a proprietary turning gear mechanism further reduces maintenance time and improves overall service efficiency.
