Abstract:
An aftertreatment system comprises an exhaust reductant storage tank and a SCR system including a catalyst fluidly coupled thereto. The aftertreatment system also includes a controller configured to interpret an output signal indicative of a catalytic efficiency of the catalyst. The output signal is filtered using a fast filter to obtain a fast filter response signal, and also using a slow filter to obtain a slow filter response signal. It is determined if the fast filter response signal exceeds a first threshold and if the slow filter response signal exceeds a second threshold. In response to determining that the fast filter response signal exceeds the first threshold, and the slow filter signal response exceeds the second threshold, an indication is provided that an improper exhaust reductant is present in the storage tank.
