ABSTRACT:
A filtration system is disclosed which removes particulates from the exhaust gas of a diesel engine. The system has (a) a filter element, (b) oxidation means for conducting a flow of heated gas through at least a portion of the filter element, the heated gas being effective to ignite the particulates in that portion, and (c) a flow control means. The flow control means has walls dividing the filter element into first and second portions, and a flow diverter effective to normally permit full exhaust gas flow through both of said filter portions, and effective to selectively permit exhaust glow through only one of the filter portions while permitting flow of heated gas of the oxidation means through the other of said filter portions.
