Abstract:
A reductant insertion system for delivering a reductant to an aftertreatment system comprises a reductant storage tank configured to store a liquid reductant. A pressure relief valve is operably coupled to the reductant storage tank. The pressure relief valve is configured to selectively open in response to a reductant gas pressure in the reductant storage tank exceeding a predetermined reductant gas pressure threshold. A reductant insertion assembly is fluidly coupled to the reductant storage tank and configured to deliver the liquid reductant to the aftertreatment system. The reductant insertion assembly comprises a shutoff valve configured to be selectively closed in response to a liquid reductant pressure in the reductant insertion assembly exceeding a liquid reductant pressure threshold, so as to stop delivery of the reductant from the reductant storage tank to the reductant insertion assembly.

Claim (Index 20):
The aftertreatment system of  claim 13 , wherein the reductant insertion assembly further comprises a dosing valve fluidly coupled to the selective catalytic reduction system, and wherein the controller is further configured to:\n determine an amount of the liquid reductant to be inserted into the selective catalytic reduction system for optimal decomposition of NOx gases included in the exhaust gas; and open the dosing valve for a predetermined time so as to insert the determined amount of liquid reductant into the selective catalytic reduction system.
