Designed for demanding marine operating conditions, the Yuchai YC6TF Marine Auxiliary Engine provides stable and efficient auxiliary power for a wide range of vessels. By combining advanced combustion technology with a robust structural design, this engine achieves an excellent balance between performance, economy, reliability, and service convenience, making it a dependable choice for long-term marine operation.

High Economic Efficiency

Four-valve technology significantly increases intake and exhaust airflow, which improves air exchange efficiency. Fuel atomization becomes more uniform, combustion more complete, and exhaust smoke visibly lower. As a result, fuel consumption stays low, the fuel curve remains flat, and the economic operating range expands, helping operators reduce overall running costs.

Safe and Reliable Operation

A high-strength alloy cast iron cylinder block paired with an integral forged steel crankshaft ensures stable operation under continuous load. This robust structure enhances resistance to fatigue and wear, supporting safe engine operation and extending service life for long-term reliability.

Easy Maintenance

The modular design simplifies installation and servicing. Wet cylinder liners, a single-cylinder single-head configuration, and side inspection windows on the cylinder block provide convenient access during maintenance. Therefore, routine servicing becomes faster and more efficient, reducing downtime and maintenance effort.

High Performance

High-efficiency turbocharging and intercooling technology increases specific power output and delivers higher torque. With sufficient power reserves, the engine adapts well to various operating conditions and maintains high working efficiency, ensuring reliable auxiliary power support during demanding marine operations.
