Underflow selective catalytic reduction steady state ammonia slip detection with positive perturbation

A method for treating exhaust gas from an internal combustion engine including, determining if a steady state condition exist and perturbing a reductant injection corresponding the steady state. Measuring a first and a second NOx values corresponding to the steady state and resulting from the pertur...
