An engine system having a reductant delivery and storage system is described. In one example, a physical condition associated with a reductant storage device is correlated with a characteristic of a fluid stored in the reductant storage device to determine the availability and make-up of the stored fluid. In response, engine operation may be adjusted.

Approach for detecting reductant availability and make-up

Methods for updating the PF soot load of an engine are provided herein. In one example, a soot storage estimate is based on processing operations that occur at different timings. The method can improve soot estimation during some conditions.

Determination of diesel particulate filter load under both transient and steady state drive cycles
