Which consequence results inside a catalytic converter when the air-fuel ratio fluctuates rapidly?

💡 Explanation

When the air-fuel ratio fluctuates, the oxygen storage capacity of the catalytic converter is exceeded, causing a decrease because the redox environment is disrupted, which inhibits the NOx reduction efficiency. Therefore the reduction efficiency drops, rather than the other effects that each optimize based on distinct stoichiometry ranges.
