What is a Catalytic Converter?

A catalytic converter is a pollutant air defence system in your car. It locates between the engine and the muffler in a car.

It’s ordinarily ceramic-coated beads with precious metals like canister, platinum and palladium etc., as the catalysts.

A catalytic converter is the final defence against harmful gases and pollutants which emit from car. Its main job is to convert harmful and unburned gases into harmless gases.

In a Catalytic converter,  carbon monoxide turns into carbon dioxide, hydrocarbons turn into carbon dioxide and water, and nitrogen-oxides turn back into nitrogen and oxygen gases. 

Signs of Bad Catalytic Converter

A good catalytic converter can serve you for more than ten years or even longer. But it can be harmed; due to contaminants, clogging, overheating or physical damage. Leaded gas also reacts with catalyst metals and causes damage. 

Leakage in the combustion system may spread air coolants into the catalytic converter. Liquids in the catalytic converter can clog air ventilation through it.  However, if the catalytic converter goes bad, you should diagnose it as soon as possible. 

Here are some symptoms that may indicate a faulty catalytic converter.
