What does a catalytic converter do?

An automotive catalytic converter is an emission control device that reduces harmful emissions and toxic gases such as hydrocarbons, carbon monoxide, and other pollutants in exhaust from an internal combustion engine into less toxic pollutants by catalyzing what's known as a "redox reaction". Located in the exhaust system along with the muffler, catalytic converters are one of the last filtering mechanisms for air pollution from vehicles before the exhaust pipe.

What are the signs of a malfunctioning catalytic converter?

Sluggish engine performance, reduced acceleration, dark exhaust smoke, the smell of sulfur or rotten eggs from the exhaust, the "check engine" light coming on, and excessive heat under the vehicle are some of the symptoms that may suggest it's time for a catalytic converter replacement. Failing a smog emissions test is also a sure sign that it may be time for a catalytic converter repair.

Catalytic converters contain a part which is structured like a ceramic honeycomb (covered with tiny pores) that are coated with platinum, rhodium, or palladium. Although the quantities vary by model and make, on average a standard catalytic converter contains about 3-7 grams of platinum, 2-7 grams of palladium and 1-2 grams of rhodium. Due to its importance in cutting emissions, and the precious metals it contains, unfortunately catalytic converter thefts are quite common.

NAPA carries a wide variety of parts to help you replace your catalytic converter or repair your exhaust system. We carry catalytic converter adapters, catalytic converter air tubes, catalytic converter flange stud kits, catalytic converter heat shield retainers, catalytic converter pipes, diesel oxidation catalysts, spring kits, and catalytic converter installation kits.
