METHOD FOR DETECTING THE DEGREE OF AGING OF CATALYTIC CONVERTERS |
| 摘要 |
The invention is directed to a method for determining the state of aging of a catalytic converter (2). The disclosed method functions in a non-contacting manner as resonances formed when the catalytic converter (2) located in a housing is excited with high-frequency electromagnetic waves are analyzed. |

1. A method for the noninvasive detection of the degree of aging of an automotive exhaust gas converter which is located in a metallic catalytic converter housing, via emission of an alternating electromagnetic field and detecting the same, wherein the adsorption of water on the catalyst surface is determined using certain resonance characteristics at a catalyst temperature of <200° C., and the degree of aging of the catalytic converter is thereby inferred. |
