Impact of internal combustion engine overheating on lubricating oil degradation

Abstract

The study analysed the impact of overheating of internal combustion engines on lubricating oil degradation. It highlighted that malfunctioning of key components, such as radiators, coolant conductors and water conductors, contributed significantly to overheating. Problems such as dirt and sludge build-up, leaks and blockages in these systems reduced cooling capacity, which accelerated oxidation, decomposition and sludge formation in the lubricating oil. This led to a deterioration in engine efficiency and shortened the service life of engine components. In addition, the investigations underlined the importance of preventive maintenance, including radiator cleaning, periodic replacement of hoses and thermostats, as well as the use of materials with advanced thermal properties. These methods were proposed as solutions to minimise the risks of overheating, especially in areas of high climatic temperatures. The study also explored the feasibility of advanced technologies, such as monitoring systems and high-performance coolants, to optimise engine performance. These findings offer valuable information for users, technicians and manufacturers, enabling improved design and maintenance of engines that are more resistant to overheating. Finally, it was emphasised that proper knowledge about the functioning of cooling systems is crucial to ensure efficient vehicle performance and avoid costly repairs.
