EN Compression ignition engines have no possibility for self-regeneration of DPF and regeneration requires additional energy for soot combustion (additional fuel or electric energy) after some period of the engine work as a result of closing of substrate pores by soot. The innovation method takes into account a self-regeneration of diesel particle filter by use of special heat recovery system. The paper shows one of possible design of DPF self-regeneration. The exhaust temperature behind the turbine and catalytic converter is very low and for an increasing of gas temperature before DPF, the heat from soot combustion can be used. The preliminary studies show a possibility of using the special design of DPF with heat recovery system. The paper presents results obtained from simulations based on one-dimensional model of such system and analysis of increasing the heat recovery ratio by change of geometry of DPF. The gas heat exchange formulas between DPF and the heat exchange model are partly included in the paper. The preliminary results of calculations show the possibility of increase of exhaust gases in front of DPF about 20%, which enables a continuous regeneration of DPF. Heat recovery ratio is depends on soot combustion rate on the wall of DPF monolith. The method enables to recover some part of energy which is lost in the conventional DPF. The paper is a part of further work in European project FP6 IPSY.
