Mann, G S; Parker, W J; Tendulkar, D V

A diesel particulate trapping and incineration system is disclosed that includes a porous wall monolithic ceramic filter element having dual openended inlet passages separated from adjacent exhaust passages by particulate filtering porous walls. A balancing system for the distribution and incineration of particulates is provided including dual inlet ducts feeding exhaust gases to both ends of the inlet passages and valve means for controlling the amount of inlet gas flow entering the open opposite ends of the inlet ducts. In this way control is obtained of distribution of particulates over the length of the inlet duct walls as well as of the incineration of particulates upon heating of the exhaust gases to incineration temperature.
