What Is the Operating Temperature of a Catalytic Converter?
The normal operating temperature of a catalytic converter is between 550 and 1,600 degrees Fahrenheit with the optimum temperature being about 806 degrees. High operating temperature can be a sign of extra pollutants in the exhaust system. It can also result from excess fuel going through the exhaust system.
A catalytic converter is designed to remove harmful emissions from the exhaust of a vehicle or other piece of machinery before they are released into the atmosphere. The original converters, called two-way converters, reduced carbon monoxide by combining it with oxygen, creating carbon dioxide. Modern converters for passenger cars do the same plus convert nitrogen oxides into nitrogen and oxygen and hydrocarbons into water and carbon dioxide.
