ABSTRACT:
A method of directing flow of exhaust gas includes directing a first portion of the flow through a first flow path and directing a second portion of the flow through a second flow path. A temperature of at least a portion of the flow in the first flow path is increased, and the flow in the first flow path is sent through a filter. The first and second portions of the flow downstream of the filter to are combined form a combined flow. The combined flow is maintained within a predetermined range of temperatures, and the combined flow is directed to a catalyst.
