EN This paper presents the modelling of the heat loads in the dry and wet cylinder sleeve in unsteady state. Next compared the results obtained temperature distribution on the individual surfaces of the dry and wet cylinder from the moment of starting the turbocharged Diesel engine to the moment when the distribution of the temperature changed in a small range. Modelling was conducted based on the boundary conditions III kind as a function of time, which describes the convective heat transfer coefficient and the temperature of the surrounding surfaces of cylinder sleeve, appointed on the basis of the bizonal model. The thesis used thefinite elements method (FEM). The calculations show that topparts of the cylinder sleeve near of the mount flange heat up thefastest however the temperature in the bottom parts below the 3rd ring in the piston is the lowest. Higher temperature of the dry cylinder sleeve in relation to the wet is caused by the fact that different convective heat transfer coefficients on the side of the liquid coolant were assumed. The highest difference of average temperature occurs in the initial phase of heating up of the dry and wet cylinder sleeve between 5 and 15 second. In the result of carried out calculations it was stated that the cylinder sleeve fastest heats up during first 20 second of the engine work then the temperature starts to stabilize and in 40 second it changes in a small range.
