This paper presents a two-dimensional model of heat flow through structural elements of cylinder of two--stroke cross-head engine of longitudinal scavenging, obtained with the use of the elementary balance method. Special attention was paid to the modelling of temperature distribution within engine cylinder liner of „wet” construction. For modelling the unsteady heat flow multi-dimensional equations with Dirichlet -- Fourier boundary conditions, were used. For the Fourier boundary conditions in the engine cylinder space local values of convective and radiant heat-transfer coefficients were applied. For calculations the KM3Rmethod of solving differential equations, based on the elementary balance method, was used. Modelling results have been presented in the form of the temperature field of engine cylinder structural elements infunction of the changeable angle of crankshaft position
