ABSTRACT:
A catalytic converter has an inner region and a jacket surface surrounding the inner region and being disposed approximately parallel to a given flow direction. The inner region conducts a flow of a fluid containing ingredients to be converted in the inner region by a catalyzed exothermic reaction. The flow passes through the inner region in the given flow direction. The reaction zone is defined as a part of the inner region in which a reaction predominantly takes place. A method for detecting a reaction zone in the catalytic converter includes detecting the reaction zone by measuring a distribution of temperature over the jacket surface along a measurement path being aligned approximately parallel to the given flow direction. The reaction zone is determined by a segment of the measurement path at which the temperature deviates by less than a predetermined limit value from a maximum value of the temperature over the measurement path.
