As vital components of diesel engines, failure issues of cylinder liner-piston ring components (CLPRs), which work under harsh conditions of high temperature, high pressure, and heavy load, become a technical shortcoming of performance improvement and service life for diesel engines. Online condition monitoring and maintenance based on the operating conditions of CLPRs are considered an effective method for ensuring normal diesel engine operation. For this reason, a comprehensive overview for condition-monitoring technologies, including lubricating oil and vibration condition monitoring, and wear-repairing strategies was necessary. However, such an overview, to the best of our knowledge, is needed in related research fields of condition monitoring and maintenance regarding diesel engines and its components. This paper systematically reviewed the research progress of online condition monitoring and self-repairing techniques for in-service diesel CLPRs from the perspective of tribosystems. To contextualize this concern, an initial review of various condition-monitoring techniques, such as lubricating oil, mechanical vibration, essential state parameters, and acoustic emission technology were specifically discussed. Subsequently, real-time maintenance strategies based on lubricating oil self-repairing additives were comprehensively summarized. Finally, this review concluded with a brief discussion of shortcomings and plausible future trends for various techniques. This study tackled wear-induced failure issues of CLPRs by reviewing online condition techniques and in-time maintenance methodology, providing a theoretical foundation and technical assistance for the development of operation and maintenance guarantee systems for marine diesel engines and intelligent engine rooms in the near future. |
