Abstract:
The present application provides an aftertreatment system for treating an exhaust stream of an engine. The aftertreatment system may include a selective catalyst reduction system positioned downstream of the engine, a secondary catalyst positioned downstream of the selective catalyst reduction system, a first gas sensor positioned between the engine and the selective catalyst reduction system, a second gas sensor positioned between the selective catalyst reduction system and the secondary catalyst, and a third gas sensor positioned downstream of the secondary catalyst.

Claim (Index 15):
A method determining a flow rate of a reductant in an aftertreatment system for an exhaust stream of an engine, comprising:\n receiving a first input from one or more first gas sensors positioned between the engine and a selective catalyst reduction system to determine a first concentration of ammonia (NH 3 ) and a first concentration of NOx in the exhaust stream; receiving a second input from one or more second gas sensors positioned between the selective catalyst reduction system and a secondary catalyst to determine a second concentration of ammonia (NH 3 ) and a second concentration of NOx in the exhaust stream; receiving a third input from one or more third gas sensors positioned downstream of the secondary catalyst to determine a third concentration of ammonia (NH 3 ) and a third concentration of NOx in the exhaust stream; estimating a first change in the exhaust steam between the first gas sensor and the second gas sensor; estimating a second change in the exhaust stream between the second gas sensor and the third gas sensor; and varying a flow rate of a reductant to the selective catalyst reduction system based upon the first change and the second change.
