Abstract:
An exhaust gas treatment system for an internal combustion engine may have a reductant delivery system that delivers reductant to an exhaust stream in an exhaust aftertreatment system. A temperature sensor may be positioned in or near the flow of reductant and exhaust to measure the temperature of the reductant and exhaust. A change in temperature over time, such as an increase, decrease, or change in variation amplitude, may indicate the presence of a reductant deposit in the system. Detection of the deposit may initiate a regeneration cycle in which the operating characteristics of the system change to eliminate the reductant deposit to prevent it from hindering the performance of the exhaust aftertreatment system.

Claim (Index 1):
A method for diagnosing existence of a reductant deposit in an exhaust aftertreatment system that delivers reductant to exhaust gas produced by an internal combustion engine to provide a mixture of exhaust gas and reductant, the method comprising:\n sampling a temperature of the mixture of exhaust gas and reductant with a temperature sensor positioned in or near the exhaust aftertreatment system; determining when the temperature is below a predetermined temperature value; in response to the determined temperature being below the predetermined threshold value, determining a presence of a reductant deposit in the exhaust aftertreatment system; and in response to determining the presence of the reductant deposit, initiating a regeneration cycle of the internal combustion engine to increase a temperature of the exhaust gas flowing through the exhaust aftertreatment system to at least partially remove the reductant deposit.
