Abstract:
An aftertreatment system comprises an aftertreatment component structured to decompose constituents of an exhaust gas produced by an engine. A reductant insertion assembly is fluidly coupled to the aftertreatment component and configured to insert a reductant therein. A controller is operatively coupled to the reductant insertion assembly and configured to instruct the reductant insertion assembly to insert the reductant into the aftertreatment component for a first insertion time between first time intervals. The controller determines an operating condition of the engine, and determines if the operating condition satisfies a predetermined condition. In response to the predetermined condition being satisfied, the controller instructs the reductant insertion assembly to insert the reductant into the aftertreatment component for a second insertion time between second time intervals. The second insertion time is longer than the first insertion time.

Claim (Index 20):
A method for preventing degradation in a performance of an aftertreatment system due to increase in a time period for which a reductant is inserted into the aftertreatment system, comprising:\n inserting the reductant into the aftertreatment system for a first insertion time between first time intervals; initiating a free-running counter in response to receiving a reductant insertion request; resetting the free-running counter after the first insertion time is complete, the first insertion time corresponding to a first volume of the reductant inserted into the aftertreatment system during a normal operation of an engine fluidly coupled to the aftertreatment system; if a predetermined condition of the engine is satisfied, inserting a second volume of the reductant into the aftertreatment system in a second insertion time, the second insertion time longer than the first insertion time; integrating the first volume of the reductant using an integrator so as to determine an integrated volume, the first volume integrated until the integrated volume is equal to or greater than a second volume corresponding to the second insertion time; resetting the integrator once the integrated volume is equal to or greater than the second volume; and in response to the integrated volume being less than or equal to the second volume, stopping insertion of the reductant into the aftertreatment system until the integrated volume is greater than the second volume.
