![]() Not only that, but they'll oxidize any leftover hydrocarbons as well as they pass through. Then, platinum and palladium use the remaining oxygen molecules by combining them with carbon monoxide to create CO2. Platinum and rhodium pull oxygen off the nitrogen atoms, causing the harmless nitrogen to exit the exhaust. This is one of the reasons catalytic converters carry a high price tag. Why? Because they contain several rare metals, including platinum, palladium, and rhodium. If you didn't know, catalytic converters are a popular target for thieves. What's inside a catalytic converter? First, there's ceramic, which doesn't react with anything, but it does get super hot, allowing the reactions to occur. The components inside act as a catalyst to help convert these toxic substances to something less harmful. ![]() Here's where a catalytic converter comes in, which was first patented back in 1950 by a French chemical engineer named Eugene Houdry. Additionally, if any of the hydrocarbons don't burn up, they are also released into the outside air. As a result of this, carbon monoxide is made, which is a toxic substance that depletes the ozone layer. Instead, it creates molecules that don't naturally exist. However, because of the heat inside the engine, the reaction isn't perfect. In a perfect world, igniting all of these (including oxygen) would produce a harmless combination of carbon dioxide and water. ![]() Gasoline is made up of hydrocarbons, which is an organic compound consisting of hydrogen and carbon. Let's get started with the basics first! What Is A Catalytic Converter And What Does It Even Do? Lastly, we will review what causes a catalytic converter to fail, and how much it costs to repair or replace one. Then, we'll examine a few of the main signs that suggest yours is failing (or has already failed). We'll first take a closer look at what it is and how it works. Thankfully, in this guide, we will cover everything you need to know about catalytic converters. If yours is failing, it will no longer be able to do this effectively, meaning your car likely will not pass a smog test. What is a catalytic converter? It is an emissions control device located near the exhaust manifold that reduces the toxicity of what comes out of the tailpipe. However, until the internal combustion engine is totally phased out, we will have to rely on catalytic converters to achieve this goal. The main one is to reduce emissions, which is the number of gases and particles exiting the tailpipe. There are many reasons automakers are making a push towards electric vehicles.
