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 14):
A method of reducing noise produced by a reductant insertion assembly of an aftertreatment system receiving exhaust gas from an engine, the method comprising:\n inserting a reductant into the aftertreatment component for a first insertion time between first time intervals; determining an operating condition of the engine; determining if the operating condition satisfies a predetermined condition, the predetermined condition comprising at least one of a vehicle speed being less than a predetermined speed threshold, an engine speed being less than an engine speed threshold, an engine torque being less than an engine torque threshold, and an exhaust gas mass flow being less than an exhaust gas mass flow threshold; and in response to the predetermined condition being satisfied, inserting the reductant into the aftertreatment system for a second insertion time between second time intervals, the second insertion time longer than the first insertion time.
