Which outcome limits catalytic converter efficiency near startup?

💡 Explanation

Emissions increase because catalytic converters rely on a minimum light-off temperature for activity; the catalyst's thermal mass heats slowly, therefore conversion remains low, rather than precious metal disruption causing deactivation at startup.
