ABSTRACT:
A method for simultaneously measuring one or more properties (e.g. temperature, concentration of NOxand ammonia, etc) in an exhaust gas mixture. Signals from one or more sensors that are cross-sensitive to one or more gases can be combined. A decoupling observer algorithm can be applied, such that these cross-sensitivities are decoupled. The sensors simultaneously obtain an estimate of one or more gases in the diesel exhaust. A decoupling observer algorithm can be structured and arranged to be operable among a plurality of positions corresponding to several internal configurations.
