What temperature can be expected on the surface of the catalytic converter?

The surface temperature of a catalytic converter typically ranges from 400 to 800 degrees Fahrenheit (200 to 427 degrees Celsius) during normal operation. However, under certain conditions, such as excessive fuel enrichment or malfunction, temperatures can exceed 1,600 degrees Fahrenheit (871 degrees Celsius). This high temperature is necessary for the catalytic reactions that reduce harmful emissions from the exhaust gases. Proper functioning and design are crucial to maintain these temperatures within safe limits to avoid damage.
