Thermal-Mechanical Analysis of the Cylinder of the Four-stroke Engine

This diploma thesis is focused on creating a finite element method model of a four-stroke engine with a purpose to determine an impact on cylinder bore distortion caused by several types of loading. Introduction of this work covers research of possibilities in modelling thermal-structural analysis of cylinder liner and verifications of the analysis results. An Ansys model was further created and cylinder liner radial deformation caused by head bolts tightening and thermal loading coming from combustion was determined. Finally, a whole engine working cycle was simulated with a gas pressure loading and its final impact on the total cylinder liner radial deformation was defined
