This paper deals with the modelling of heat flow through cylinder liner structural components of a two-stroke engine. Especially, I paid attention to simulating temperature distribution for the wet cylinder liner. Multidimensional equations for the transient heat conduction with the Dirichlet and Fourier boundary conditions have been applied. In particularly, local values for the convective and radiative heat transfer coefficients using the Fourier boundary conditions determined in space of cylinder volume are applied. In order to determine the temperature distribution for the considered space, the radiosity method is used. Simulation results have been presented in the form of a temperature field for cylinder liner structural components depending on the crankshaft position angle. Application of the iterative calculation method for solving differential equations of energy balance allowed me to use software easy to get. I carried out all iterative computations using MSEXCEL spreadsheet. This way, I could decrease the simulation cost significantly. The simplicity of such an approach allowed me to apply the obtained results for visualization of the conduction heat transfer phenomena occurring in a cylinder of working marine engine. The presented approach could be used for the development of ship machinery simulators as well.
