The main problem in conventional diesel engines and HCCI diesel is reduction of solid particles emitted to atmosphere. applying of particle filters requires special methods for their regeneration after some period of the engine work in a result of closing of substrate pores by soot. These methods require additional energy for combustion of soot (additional fuel or electric energy). The new method takes into account a self-regeneration of diesel particle filter by use of special heat recovery system. The paper shows an example of DPF self-regeneration. the exhaust temperature behind the turbine and catalytic converter is very low and particularly for HCCI engine the emission of particles is low in comparison to conventional diesel engines. for that case an additional energy is required for increase of gas temperature before DPF. the preliminary studies show a possibility of using the special design of DPF with heat recovery system. the paper shows the simulation results of such system and possibility of increasing the heat recovery ratio by change of geometry of DPF. the gas heat exchange formulas between dpf and the heat exchange module are partly included in the paper. the preliminary results of calculations shows the possibility of increase of exhaust gases in front of DPF about 20%, which enables a continuous regeneration of DPF. the work is carried out as part of the european project ipsy.
