ABSTRACT
Radiation is considered to be an important mode of heat transfer in diesel engines. It is mainly caused by a presence of soot particles in combustion gases. Spatial distribution of radiative heat flux on walls of the combustion chamber can be an important factor of thermal load of some parts of the engine. The paper presents a numerical method used for solution of an integral equation resulting from mathematical description of variation of radiative heat flux on the walls of the combustion chamber. Preliminary results showing heat flux distribution for selected values of the crank angle and wall emissivity are also included.
