Method and apparatus for estimating a dosing-error in a selective catalytic reduction system |
abstract |
A method and apparatus for determining if a selective catalytic reduction (SCR) device is being mis-dosed with a reductant comprises (i) determining a NOx readout difference figure from the difference between an expected exhaust gas output from the SCR and a measured exhaust gas state from the SCR device; and (ii) determining a mis-dosing indication figure which indicates if the SCR device is being under, over or correctly dosed by cross-correlating the NOx readout difference with a NOx sensor sensitivity figure, wherein the NOx sensor sensitivity figure is an indication to how sensitive the measured exhaust gas output state is to dosing errors. Also shown is a method and apparatus that comprises determining a first cross correlation figure by cross-correlating a measured exhaust gas figure with a NOx sensor sensitivity figure; determining a second cross-correlation figure by cross correlating an expected exhaust gas figure with a NOx sensor sensitivity figure; and determining a mis-dosing indication figure from the difference between the first and second cross-correlation figures. |
