Today, we are diving into the catalytic converter, a car part found in most modern cars.
To begin, the catalytic converter's primary function is to reduce harmful pollutants in your car's exhaust gas, by transforming the gas into less toxic parts.
So, what exactly does this converter look like? Usually, catalytic converters are quite long and round. They hold a ceramic core with a honeycomb structure inside. The gas is pressed through this structure where the chemical reactions can take place. You'll find the catalytic converter sitting as the last part right before the exhaust pipes. They’re normally easy to spot if you look under your car.
Beware that electric vehicles do not have catalytic converters as they don't emit exhaust gases.
Locating the catalytic converter in your car isn't too hard. Like I said, It is typically found along the exhaust pipe that connects to your engine, somewhere between the muffler and the exhaust pipe - the muffler dampens the car’s sound - and we’ll get to that car part in another episode soon.
Sometimes the catalytic converter can be hidden behind a protective shield. But remember to always make sure the car is cool before touching anything back there - to avoid any injuries as these parts can get really hot.
Now, let's talk about its lifespan. Generally, a catalytic converter can last up to ten years or more. However, its longevity is affected by the weather in your area as it can often rust over time. If your exhaust smells more than usual or you notice slower acceleration, it might be a sign that the catalytic converter needs a check.
Coming to the cost aspect, a new catalytic converter can range anywhere from 600 to 2,500 dollars. But if you're on a budget, you might consider getting one from a scrap yard which would cost significantly less. Keep in mind that replacing a catalytic converter can cost between 150 and 400 dollars, excluding the price of the part itself. The variation in the cost is often due to the accessibility of the converter in different car models.
In case you are wondering what happens when it breaks, be prepared for lower fuel efficiency and power, especially during acceleration. A malfunctioning catalytic converter might also cause the gas to smell like rotten eggs, and a rattling noise from the back of the car could also mean that the catalytic converter is getting worn.
Can you continue driving with a faulty catalytic converter? Technically yes, but it's not recommended due to the harmful gasses and it can also cause damage to your car's engine or exhaust system. It could actually have legal implications depending on the emission regulations in your area.
If you want to learn more about the catalytic converter, there’s a link in the show notes to an article where I dive a bit deeper. There are also pictures to help you understand it all better. There’s also a link to an overview of all the main parts of the car so you can learn about them too.
Well, that’s it! Next week we’ll have another car part ready for you!
Until then , take care and drive safely!
