What does a catalytic convertor do ?

We have known about mufflers, exhaust pipes and many other. We do see many cars around us and find many different types of cars. As many cars we see, there are twice and thrice the number of muffler types and the modifications for the car. What is a catalytic convertor?

A catalytic convertor is also a device fitted in the car which helps to reduce the effect of harmful gases coming out of the exhaust. Sometimes, the combustion of the petrol or diesel is not complete, the energy will not be converted efficiently and many harmful gases will be released from the exhaust. Due to this, there exists a lot of pollution and environmental damage. For this reason, specially designed catalytic convertors are used. They are designed in such a way that they will eliminate or almost convert the harmful gases to non-harmful gases.

Three poisonous gases comes out from incomplete combustion of fuel from the engine. They are as follows-

  1. Hydrocarbons.
  2. Carbon Monoxide
  3. Nitrogen Oxides

Carbon Monoxide is very harmful for any human or any animal breathing in.  This causes many diseases in animals and humans too. Nitrogen oxide leads to acid rain which causes many damages to buildings and monuments. Hydrocarbons produces smog.

Catalytic convertors use a process to convert the poisonous gases to non-harmful gases. They use a catalyst to create a chemical reaction, which converts the poisonous gases to non-harmful gases. As in the carbon di-oxide preparation, we use sand as a catalyst, here we convert the poisonous gases. As we make a count on these gases, we have recorded that almost 90% to 95% of the harmful gases were converted to non-harmful gases. Breathing in carbon monoxide, hydrocarbons and nitrogen oxides causes many diseases and so reduction of these quantities will be a wise idea. Now we can breathe easily even when there are many cars on the road without face masks.
The catalyst used will be used for converting the nitrogen oxides to nitrogen and oxygen. The catalyst can be used to oxidize carbon monoxide to carbon dioxide. It can be used to oxidize unburnt hydrocarbons to carbon dioxide and water.


Once the catalytic convertor is installed in the car, you need to take care of many aspects like replacing, cleaning and all. Once when the time comes to replace, we need to buy another catalytic convertor. In many countries and in many states, the installation of a catalytic convertor is not legal. For example, in United States of America, the installation of catalytic convertor is not legal. It is made legal only after a detailed tests are conducted.


There is another reason to insert a catalytic convertor. The performance of the exhaust system will be drastically improved and you will b surprised with that performance. Many big brands like Corsa, Toyota and many other recommend using a catalytic convertor. Mega flow catalytic convertor is highly recommended for cars of suitable type by any state in the united states.
