ABSTRACT:
A diesel exhaust particulate filter contains a high temperature depth type filter material arranged in a reflexive path throughout which diesel particulates are collected from engine exhaust gases passed therethrough. Upstream and downstream portions of the filter flow path are disposed in heat exchange relation. Upon heating of the incoming gases to the incineration temperature of collected particulates, the heat of combustion in the downstream portion will be partially transferred to the upstream portion, providing more even temperature levels and improving balance of the incineration process.
