Abstract
An exhaust treatment method is provided. Method of increasing activation of NOx reduction catalyst using two or more reductant is discussed. The NOx catalyst is disposed to receive both the exhaust stream and reductant stream. The sensor is disposed to sense a system parameter related to carbon loading of the catalyst and produce a signal corresponding to the system parameter. The controller is disposed to receive the signal and to control dosing of the reductant stream based at least in part on the signal. The method includes sensing a system parameter related to carbon loading of a catalyst, producing a signal corresponding to the system parameter and sending the signal to a controller; and controlling a dosing of a reductant stream based at least in part on the signal.
