What is a catalytic converter (environmental canister) in a car? What are the reasons for its damage?

To understand why the catalytic converter (environment box) is damaged, you need to know how it works. The catalytic converter is part of a vehicle’s exhaust system. It converts the harmful gases in the exhaust into harmless gases. The catalytic converter is like a muffler in shape between the engine and the muffler. It’s on the underside of the car, usually under the rear passenger seat. You might have felt its warmth through the ground on a long drive.
After exhaust gases from the engine pass through the catalytic converter, the gases pass through a muffler, which may be more than one muffler in a single car depending on the vehicle’s design. The catalytic converter generally extends the life of the car and most of the problems are that it is subjected to clogging.
Inside the catalytic converter is a set of passages of ceramic material, a chemical reaction takes place between the converter body and the exhaust gases to make the pollutants less harmful. There are several passages for exhaust gas flow, to allow maximum surface area for hot gases to pass.
Causes of catalytic converter damage
There are two ways that a catalytic converter can be damaged:

• It can be blocked.
• It could be poisoned.

There is actually no “check port” for the consumer or mechanic to see an actual blockage in the transformer. Often, the only way to tell if the catalytic converter is not working properly (it’s plugged in) is to remove it and check for the change in engine performance. When a clogged converter is suspected, some mechanics temporarily remove the O2 sensor from the exhaust pipe before the catalytic converter and look for a change in performance.
The catalytic converter relies on receiving the right mixture of exhaust gases at the right temperature. Any additives or malfunctions that alter the mixture or the temperature of the exhaust gases reduce the efficiency and life of the catalytic converter.
Excessive use of leaded gasoline can shorten the life of the catalytic converter.
The catalytic converter can also be damaged due to poor quality exhaust valves used.
