Performance analysis of turbocharger rotor friction pairs of an automobile engine

Abstract

Turbochargers are used in modern engines to increase their performance by increasing the amount of air supplied. To increase wear resistance, researchers and engineers are improving integrated technologies for strengthening turbocharger assemblies. The purpose of this study is to evaluate and analyze the influence of integrated strengthening technologies on the wear resistance of the turbocharger assembly. Integrated strengthening technologies include the use of new materials, coatings, design changes and manufacturing processes that improve the strength, thermal stability and wear resistance of the turbocharger assembly. A comprehensive analysis was carried out, including experimental tests, mathematical modeling and numerical simulations. Analyzed tests of wear resistance on specially designed stands simulating the real operating conditions of turbocharger units. The results can be used to analyze the effect of integrated strengthening technologies on wear resistance, considering various parameters such as temperature, torque and operating time.
