What is a Catalytic Converter?

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.While pollutant gasses are comprised of harmful molecules, those molecules are composed of atoms. Because of this, the best way to break down the gasses is to split the particles after they leave the engine but before they enter the air.

This is what a catalytic converter does.

While this may sound like a complicated process, it’s quite simple. Catalysts are chemicals that speed chemical reactions without changing their overall process. A catalytic converter, meanwhile, is a metal implement bolted to the underside of the car. It is comprised of an input and output pipe. The input pipe pulls hot fumes from the engine, while the output pipe pushes vapors out. As the gasses from the engine blow over the catalyst, it creates a series of chemical reactions designed to alter the gasses and convert them into gasses that will not harm the environment.

While catalytic converters don’t eliminate air pollution, they can be instrumental in reducing immediate, localized air pollution, including pollution from roadways. Catalytic converters also work best when they’re warm, which takes about 10-15 minutes of driving or idling. This means your car may still churn out emissions for the first few minutes of a trip.

Types of catalytic converters

There are various types of catalytic converter. A simple ‘two-way’ oxidation cat works to turn carbon monoxide (CO) to carbon dioxide (CO2) and hydrocarbons, which are basically particles of unburnt fuel, to carbon dioxide and water.  More advanced ‘three-way’ catalytic converters are fitted to modern cars and these do the above while also reducing emissions of nitric oxide (NO) and nitrogen dioxide (NO2) which together are more commonly known as NOx, a major cause of localised air pollution.

1. Oxidation Catalyst (OC)

In the type of CCO (Catalytic Converter for Oxidation), Oxygen will react with CO and HC to form CO2 and H2O which do not contain pollution. For this oxidation process to run well.

2.Three-Way Catalyst (TWC)

Of all the types of Catalytic Converters, this one is the most ideal. In addition to CO and HC, NOx will also be converted into non-polluting substances. The NO and O2 processes will function as.


3. Three-Way Catalyst & Oxidation Catalyst

This type of Catalytic Converter is a combination of an oxidation catalyst and a three-way catalyst that aims to reduce air pollution even more optimally.
