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 16):
An aftertreatment system for treating an exhaust stream of a lean burn engine, comprising:\n a selective catalyst reduction system positioned downstream of the lean burn engine; the selective catalyst reduction system comprising an injector for a stream of a reductant; 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; a third gas sensor positioned downstream of the secondary catalyst; and a controller in communication with the first gas sensor, the second gas sensor, the third gas sensor, and the injector, wherein the controller receives sensor input from at least the second gas sensor and the third gas sensor to determine concentrations of ammonia (NH 3 ) in the exhaust stream.
