Everything you need to know about Catalytic Converters

During the 20th century, motor vehicles were the cause of majority of the world’s pollution. Since vehicle’s were a necessity, it was up to researchers to come up with a new way to tackle this debilitating issue. As a result, catalytic converters were invented, an innovative device that is capable of filtering out harmful gases from a vehicle’s exhaust system. 

Today, these devices have been mandated by the UK’s Ministry of Transport (MOT), meaning no vehicle is allowed to drive on UK roads without having a catalytic converter installed. However, many remain unaware about this device and its value. To shed some light on this matter, Turborevs features everything you need to know about catalytic converters.

What is a Catalytic Converter?

Catalytic converters are a filtering system that is attached to the exhaust backbox of a vehicle. The device consists of a honeycomb-shaped filter that is made out of a neutral material such as platinum. The harmful gases that are emitted by the car’s exhaust system pass through this filter, converting the harmful emissions into their benign counterparts.

How does a Catalytic Converter Work?

Despite seeming like a complex device, the workings of catalytic converters are quite simple. Once the gases pass through the honeycomb filter, they react with the catalyst. This reaction converts the gases into their less harmful counterparts.

This process takes place through two different reactions – oxidation and reduction. These processes convert hydrocarbons and carbon monoxide into water and less harmful oxides such as carbon dioxide.

Types of Catalytic Converters

Catalytic converters come in a few different types, however, the basic process of filtering out harmful gases remains the same. The different types are based on the kind of reaction taking place within the catalyst. There are three types in total which have been listed below.

  • Oxidation Catalyst – A simple converter that employs oxygen as a catalyst.
  • Three-Way Catalyst – A three-way catalyst uses the process of reduction, converting a wide range of gases.
  • Three-Way Catalyst and Oxidation Catalyst – These catalysts are quite versatile and use both reduction and oxidation for converting the exhaust fumes.


Catalytic converters have played an immense role in acting as a barrier against pollution and climate change. Today, these devices have become more important than ever as the world tackles climate change, and understanding how these devices work is essential.
