What Is A Catalytic Converter?

Your car’s engine produces harmful pollutants during the normal combustion process. But for the sake of the environment and people’s health such harmful things cannot be released into the environment thus they needed to be filtered out.

And this is where a catalytic converter comes in. The job of a catalytic converter is to convert all the produced harmful pollutants into less harmful gases that can be easily released into the open.

What Are The Reasons For The Damage Of Catalytic Converters?

As stated earlier, a catalytic converter is a device that is a crucial part of a vehicle’s exhaust emission control system. 

Over time filtering out the harmful gases and pollutants it is understandable that it can get clogged with all the carbon buildup. Such a build-up restricts the converter from doing its job well.
