Abstract:
An aftertreatment system comprises a SCR system including at least one catalyst. A NOx sensor is positioned down-stream of the SCR system. A controller is configured to determine an estimated engine NOx amount in the exhaust gas produced by an engine fluidly coupled to the aftertreatment system. The controller interprets an output value indicative of a first amount of oxygen in the exhaust gas downstream of the SCR system. The controller determines an adjusted engine NOx amount in response to the output value. A NOx sensor is positioned downstream of the selective catalytic reduction system and communicatively coupled to the controller. The NOx sensor is structured to provide the output value.

Claim (Index 18):
The method of  claim 16 , wherein O 2est  is determined using the following formula:\n O 2 est =\u03b2( m \u0116GR , T EGR , P EGR , m In{dot over (t)}ake , T Intake , P Intake ) \u2003\u2003(II) wherein: M \u0116GR  is a mass of exhaust gas recirculated into an engine cylinder; T EGR  is a temperature of the exhaust gas recirculated into the engine cylinder; P EGR  is a pressure ressure of the exhaust gas recirculated into the engine cylinder; m In{dot over (t)}ake  is a mass of intake gas introduced into the engine cylinder; T Intake  is a temperature of the intake gas introduced into the engine cylinder; and P Intake  a pressure of the intake gas introduced into the engine cylinder.
