What is a catalytic converter and Types of Catalytic Converters?

The catalytic converter or by the name as ‘Cat-Con’ is a mechanical device. It reduces the harmful emissions created in the exhaust system of an engine. It is am an important device as it works with the harmful gases, which the engine creates at the time of the combustion of fuel. The primary purpose of a catalytic converter is to reduce exhaust emissions.

The Cat-Con reduces the harmful exhaust gases with chemical reactions. It reacts with the harmful pollutants in the exhaust gases and turns them into the lesser harmful gases.

Types of Catalytic Converters:

There are three different types of Cat-Cons. The first type is the oxidation catalysts. It reduces the harmful pollutants such as Carbon Monoxide, and fuel hydrocarbons in the exhausts. Moreover, it often uses a secondary air injection. Moreover, the oxidation catalysts only reduce a portion of the pollutants.


The second type is the dual bed catalytic converter which provides more perfection. It works in two stages. There are two elements which are located one behind the other.

Three-Way Catalytic Converter:

The last type if the Three-Way Catalytic Converter. The three-way catalyst helps in converting the harmful gases that are exhausted from the engine into harmless gases. The engine exhausts gases contain hazardous substances that cause damage to the environment. These include the oxides of nitrogen, carbon monoxide, and hydrocarbons.
