The paper deals with the simulation of properties of IC engine equipped with a chemically inert porous media (PM) to homogenize and stabilize the combustion of CI engines. The purpose of the PM matrix use is to ensure reliable a ignition of lean mixture and to limit maximum in-cylinder temperature during combustion. It is aimed at NO formation reduction. The influence of PM on an engine cycle is examined by means of CFD simulations. Results demonstrating the influence of heat accumulation, heat supply during compression and expansion strokes and self-ignition properties of a fuel on the engine cycle are presented. All simulations involve modeling of NO formation. The homogenization capability and the flame stabilization one of the PM are discussed.
