This paper presents a new method for predicting the durability of the piston-ring-cylinder (PRC) system of an internal combustion engine based on observed changes in the physicochemical properties of the used engine oil. In the proposed method, information derived from testing the oil used in the engine is utilized to assess the durability of the engine cylinder liners.The course of changes in the proposed indicator of kinematic viscosity change intensity of the oil at temperature. When developing new power units for motor vehicles, increasing attention is paid to their durability under assumed operating conditions.
Durability, as an element of the generally understood product quality, often determines the potential user’s decision to choose a specific design or model. (…)
