The Yuchai YC8CL Marine Main Engine is a compact and high-performance marine diesel engine designed for inland waterway yachts, nearshore yachts, and official service vessels. Developed by Yuchai to meet diverse marine operating conditions, the YC8CL combines proven engineering experience with advanced diesel engine technologies. As a result, the engine delivers strong power output, smooth operation, and high reliability, making it an ideal propulsion solution for leisure and service-oriented marine vessels.

Powerful Performance

The Yuchai YC8CL marine main engine adopts efficient turbocharging and intercooling technology to achieve higher power density and greater torque output. At the same time, sufficient power reserve ensures stable performance under various operating conditions. Therefore, the engine maintains high working efficiency during cruising, maneuvering, and continuous operation.

Fuel Efficiency and Cost Savings

The YC8CL features advanced four-valve technology, which significantly increases intake and exhaust airflow. In addition, the centrally positioned fuel injector improves fuel atomization and promotes more complete combustion. As a result, the engine delivers lower smoke levels, reduced fuel consumption, and a flatter fuel consumption curve. Moreover, the wider economical operating range helps operators save fuel and reduce overall operating costs.

Easy Maintenance

The Yuchai YC8CL marine engine uses a modular design with wet cylinder liners and a one-cylinder-one-head structure. Furthermore, the engine block features side inspection windows. These design choices simplify installation, inspection, and routine maintenance, while also reducing service time and labor costs.

Compact Structure

The engine block incorporates a large number of arc-shaped structural designs, which improve overall strength while reducing weight. In addition, a compact small bore spacing design allows the Yuchai YC8CL Marine Main Engine to achieve smaller dimensions and a more compact layout, making it well suited for vessels with limited engine room space.

Safe, Reliable, and Comfortable Operation

Yuchai equips the YC8CL with a high-strength alloy cast iron engine block and an integral forged steel crankshaft. In addition, a special dual-protection anti-shock pad structure ensures safe and stable engine operation, extending service life and reliability. Moreover, the water-cooled exhaust system effectively reduces engine room temperature, creating a safer and more comfortable onboard environment.
