The method comprises generating a temporary increase in carbon monoxide levels in an exhaust gas stream, monitoring subsequent oxidizing action and determining a degree of aging of the oxidizing catalytic converter as a function of the measured oxidizing action. The method further comprises measuring a temperature rise during oxidation and correlating the aging of the converter to the speed of temperature rise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determination of a degree of aging of an oxidizing catalytic converter","description":"A method for determining a degree of aging of an oxidizing catalytic converter in an exhaust system of an internal combustion engine is provided.
