As global awareness of environmental protection increases and regulations on ship engine emissions tighten, the demand for eco-friendly marine engine technology is growing. The degradation of the tribological properties of key components can lead to decreased engine efficiency, increased fuel consumption, and higher maintenance costs due to failures. Therefore, improving the tribological properties of key engine components such as the piston ring and cylinder liner system is crucial for developing eco-friendly marine engines. This study experimentally investigates the friction and wear properties of the piston ring and cylinder liner system in marine engines. Tests are conducted under various experimental conditions using a tribo-tester designed for this system. Notably, the Stribeck curve is obtained that shows the variations in the friction coefficient with respect to the Hersey number. The wear characteristics of the cylinder liner are quantitatively assessed, and major wear mechanisms are then proposed based on experimental observations. The findings contribute to a fundamental understanding of the friction and wear characteristics of the piston ring and cylinder liner in marine engines, thus aiding in the tribological design of eco-friendly marine engines.
