The Yuchai YC8CL1630L-C20 Marine Auxiliary Engine is designed for a wide range of inland and near-coastal yachts as well as government and service vessels. Built to deliver stable auxiliary power under diverse operating conditions, this marine auxiliary engine combines strong performance, fuel efficiency, and high reliability, making it a dependable choice for modern marine applications.

Powerful Performance

The YC8CL1630L-C20 marine auxiliary engine adopts high-efficiency turbocharging and intercooling technology to achieve higher power density and greater torque output. With sufficient power reserve, the engine adapts well to various operating conditions and supports efficient onboard operations, ensuring reliable auxiliary power supply during continuous service.

Fuel Saving and Cost Efficiency

Thanks to advanced four-valve technology, the engine significantly increases intake and exhaust airflow. The centrally positioned injector improves fuel atomization and promotes more complete combustion. As a result, exhaust smoke remains low, fuel consumption is reduced, and the operating curve stays smooth. In addition, the wide economic operating range helps lower overall operating costs.

Easy Maintenance

The YC8CL1630L-C20 features a modular design with wet cylinder liners and a one-cylinder-one-head configuration. Side inspection windows on the engine block further improve accessibility. Together, these design features simplify installation, inspection, and routine maintenance, reducing downtime and service effort.

Compact Structure

The engine block uses extensive curved structural designs to increase overall strength while reducing weight. A compact cylinder center distance further minimizes engine size, resulting in a smaller and more compact auxiliary engine that fits easily into limited engine room spaces.

Safe, Reliable, and Comfortable Operation

The YC8CL1630L-C20 uses a high-strength alloy cast iron block and an integral forged steel crankshaft. A dual safety anti-shock pad structure ensures safe and stable engine operation, extending service life and improving reliability. In addition, the water-cooled exhaust manifold effectively lowers engine room temperature, providing a safer and more comfortable onboard environment.
