Abstract: A method of determining an optimized position for a burner in an exhaust aftertreatment system includes estimating temperature distributions across faces of exhaust treatment devices positioned within parallel paths based on an initial burner position upstream of the parallel paths. A temperature distribution across the faces of the exhaust treatment device is again estimated based on a changed burner position. A difference between the estimates is determined. The changing, estimating and determining steps are repeated to correlate the burner position with a temperature variance across the faces. An optimized burner position is determined based on minimizing the temperature variance across the faces of the exhaust treatment devices.
