The Yuchai YC8CAX2000L-C22 Marine Auxiliary Engine is designed primarily for 8,000–12,000-ton transport vessels and 50–70-meter fishing boats. Built to support demanding onboard power requirements, this marine auxiliary engine delivers strong output, stable operation, and long service life. By combining proven Yuchai engineering with optimized marine-specific design, the Yuchai YC8CAX2000L-C22 Marine Auxiliary Engine provides a reliable auxiliary power solution for large commercial vessels.

Powerful Performance

The Yuchai YC8CAX2000L-C22 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 high working efficiency during continuous marine operations.

Fuel Saving and Cost Efficiency

Four-valve cylinder head technology significantly increases intake and exhaust airflow. At the same time, the centrally positioned injector ensures finer fuel atomization and more complete combustion. As a result, the Yuchai YC8CAX2000L-C22 Marine Auxiliary Engine delivers low exhaust smoke, reduced fuel consumption, and a flatter fuel consumption curve, which expands the economical operating range.

Easy Maintenance

The engine features a modular design with wet cylinder liners and a one-cylinder-one-head structure. In addition, side inspection windows on the engine block allow easier access during installation and servicing. These design choices help reduce maintenance time and lower operating costs.

Compact Structure

The engine block uses a large number of curved structural designs to improve overall strength while reducing weight. A compact cylinder spacing layout further shortens engine length, making the Yuchai YC8CAX2000L-C22 Marine Auxiliary Engine well suited for engine rooms with limited space.

Safe, Reliable, and Comfortable Operation

A high-strength alloy cast iron block and an integral forged steel crankshaft ensure safe and reliable engine operation over a long service life. Moreover, the water-cooled exhaust manifold design effectively lowers engine room temperature, improving onboard safety and crew comfort during operation.
