The Yuchai YC6TF Marine Main Engine is a reliable marine diesel engine developed for inland cargo vessels and coastal fishing boats. It is well suited for transport vessels with a displacement of 3,000 to 7,000 tons, as well as trawler fishing vessels measuring 32 to 45 meters in length. Built on a proven platform, the Yuchai YC6TF Marine Main Engine delivers balanced performance, strong durability, and high operational efficiency, making it a dependable power solution for a wide range of marine applications.

High Fuel Economy

The Yuchai YC6TF Marine Main Engine adopts advanced four-valve technology to significantly increase intake and exhaust airflow. As a result, fuel atomization becomes more uniform and combustion more complete. This design effectively reduces exhaust smoke and lowers fuel consumption. In addition, the engine features a flat fuel consumption curve, which expands the economical operating range and helps operators reduce overall operating costs.

Safe and Reliable Operation

To ensure long-term reliability, the Yuchai YC6TF Marine Main Engine uses a high-strength alloy cast iron cylinder block combined with an integral forged steel crankshaft. This robust structure supports safe and stable engine operation under continuous marine working conditions. Consequently, the engine offers an extended service life and dependable performance for commercial vessels.

Easy Maintenance

The engine features a modular design that simplifies installation and servicing. Wet cylinder liners and a one-cylinder-one-head configuration make inspection and repair more convenient. In addition, the cylinder block includes side access windows, allowing maintenance personnel to perform routine service more efficiently and reduce downtime.

High Performance Output

The Yuchai YC6TF Marine Main Engine is equipped with efficient turbocharging and intercooling technology. This configuration increases power density, delivers higher torque, and provides sufficient power reserve. Therefore, the engine adapts well to various operating conditions and maintains high working efficiency during demanding marine operations.
