Abstract: Systems and methods to selectively control plurality of dosing modules may include receiving data indicative of an exhaust flow rate. An amount of reductant to be dosed may be determined based, at least in part, on the data indicative of the exhaust flow rate. A decomposition delay time may also be determined and a first dosing module and a second dosing module may be selectively activated. The first dosing module may be selectively activated at a first time and the second dosing module is selectively activated at a second time. The second time is based on the first time and the determined decomposition delay time.
