Abstract

In order to serve the design, improvement, and manufacture of engine cylinder liners, it is necessary to accurately determine its temperature distribution. This paper presents the calculation of the cylinder liner temperature distribution in a V-12 engine by the finite element method (FEM) written in ANSYS Parametric Design Language (APDL) and verified with experimental results. In this model, the process of heat transfer from the ring group and area of the piston skirt to the cylinder liner wall is considered by using the thermal circuit method. In the study, at engine speeds of 2000 [rev/min] and 1200 [rev/min], the thermal distribution of the cylinder liner is carried out at 50%, 60%, 75%, and 100% of an entire load. The results of the tests show that the theoretical model is highly reliable, with the largest relative error of 5.49%.
