Emissions System Repairs Part 1

Part one of a series on emissions system repair explores your car’s catalytic converter.

What is a Catalytic Converter?

What is a Catalytic Converter

First off though, what is a catalytic converter? A catalytic converter is a component in your car’s exhaust system that takes a catalyst and uses it to convert exhaust into harmless compounds. Your car exhaust is usually made of hydrocarbons, carbon monoxide, and nitrogen oxides. All three of these things combined make smog and lead to things like acid rain or other forms of pollution.

A catalytic converter is usually made of a platinum and palladium coated catalyst in a ceramic shell. Catalytic converters are really quite miraculous in what they do. Carbon monoxide, which is highly toxic, is converted to carbon dioxide which is not. Hydocarbons are converted into water and carbon dioxide, and nitrogen oxides are converted into both nitrogen and oxygen. But what is the most important thing that a catalytic converter does? It allows you to pass emissions testing.

Do I Need to Pass Emissions Testing?

If you live in Maricopa County, more than likely you will need to pass emissions testing in order to register your vehicle. Not every car needs to do it. Electric vehicles and alternative fuel vehicles obviously are exempt from emissions testing, and 2007 and newer models aren’t often tested for five years. Without a properly functioning catalytic converter, it’s unlikely that you will be able to pass emissions, and thus will not be able to register your vehicle.

Think for a minute what that means. No registration means that if you drive your car and get pulled over, you’ll almost certainly get a ticket. So, you have two choices open to you. You can park your car in your driveway or garage, or get emission system repair in Gilbert.

This concludes part one of our series. For more information on emission systems repair in Gilbert, be sure to read part two and part three as well
