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 23):
The method of  claim 21 , wherein a manual shutoff valve is positioned between the reductant storage tank and the reductant insertion assembly, and wherein the method further comprises closing the manual shutoff valve in response to the liquid reductant pressure exceeding the liquid ammonia pressure threshold.
