Ceramic honeycomb filters performing diesel particulate trapping require regeneration by burning the subsequently accumulated particulate. During this regeneration, thermal failure occurs in some conditions. For developing a highly reliable system with this method, it is necessary to clarify the effects of various factors on the failure to optimize the regeneration conditions. This paper gives the results of an experiment, employing a burner method, of the effect on the damage of regeneration conditions of gas temperature, oxygen concentration, gas flow rate and amount of accumulated particulate, and discusses the regeneration conditions under which the filter is safely operated.
