Modeling the performance of the "valve-guide" engine pair using modern software is an effective tool both for identifying weak points in the design and for predicting the behavior of the friction unit in operation. In this study, the method of finite element analysis was chosen as a tool to study the contact and antifriction parameters of the friction pair of the internal combustion engine "directional valve". Using the FEM application program, the raw data on the material, surface dimensions, loads, and motion kinematics are described. Based on the constructed finite-element model of the "valve-guide" conjugation, an analysis of the influence of determining tribological factors: sliding speed in contact, temperature, skew angle, friction coefficient on contact stresses both for each part of the friction pair and in the process of contact interaction was carried out. A consolidated matrix of the results of the numerical experiment was built, and the conclusions regarding the influence of each factor on the tribological characteristics were substantiated. Algorithms of influence on the design, technological and operational factors for prolonging the resource of the friction pair of the internal combustion engine "valve-guide" are outlined
