ABSTRACT:
A catalytic converter for a diesel engine comprises a stack of metal strips, coated with a combustion catalyst, the strips being spaced apart by indentations. The indentations are aligned transversely to the flow axis of the converter, and are staggered so that the exhaust gas follows a tortuous path as it flows between the strips. Particulates in the exhaust gas are trapped out in the clefts formed where an indentation presses against the adjacent strip. At intervals, fuel is injected into the exhaust gas. The fuel burns on the catalyzed surface and heats the converter sufficiently to burn the trapped particulates. In an alternative embodiment, there are two converters, and fuel is automatically injected into that converter which has more trapped particulates, so as to burn the particulates trapped in that converter.
