The Role Catalytic Converters Play In Automotive Emissions: A Serious Concern


Visitors: 149

Catalytic converters have undergone a number of changes since the 1970s. New models were introduced to replace of the power-sapping pellet catalysts of earlier times. Contemporary honeycombs used in todays catalytic converters enable easy flow of exhaust through the exhaust system of the car. At the same time, they help clean the unsafe toxin gases produced in the engine of the car. Nevertheless, the natural life of the catalytic converter is restricted yet it is one of the most important parts of a car and a compulsory one at that.

Why do we need catalytic converters?

Fuel burnt in an engine produces harmful gases such as hydrocarbons; oxides of nitrogen and carbon monoxide, which is not at all safe for the environment. At such times the catalytic converters plays the most significant role by controlling the possible damages to the environment. The catalytic converter is installed between the exhaust line and the muffler where the chemical coating of the converter works as a catalyst and changes the poisonous gases into harmless inert gases. Preserving its own chemical properties, the chemical catalyst increases the speed of the reactions between two chemicals.

OEM catalytic converters, which come with the vehicle from the manufacturer, sometimes stop functioning efficiently. All converters have to be replaced at some time or the other, but because original catalytic converters are expensive, people prefer to go for replacement converters manufactured by OEMs.

Where is the catalytic converter located?

The harmful exhaust gases enter the catalytic converter from the engine side into a sort of stainless steel container. The inside of the container has a honeycomb mesh, which is lined with catalysts such as aluminum oxide, platinum, and palladium. These catalysts change the carbon monoxide and hydrocarbons to water vapor and carbon dioxide. Some converters have a third lining of chemicals such as platinum and rhodium to reduce nitrogen oxides. Catalytic converters are also known as three-way or dual bed converters.

Do not use leaded fuel with a converter

Whether it is an OEM or any other catalytic converter, it is suggested to use unleaded fuel with it since the lead oxide produced in the fuel renders ineffective the lining of the catalyst chemicals. The only reason for using lead in the fuel is for lubrication. These days the law has made it compulsory to have Catalytic converters. Manufacturers have researched and designed special engine parts in order to withstand chemicals and the corrosive temperatures in the parts of the engine.


In comparison to any other pre-control vehicles, the utmost benefit of installing catalytic converters minimizes the amount of toxins by about 96 percent compared to vehicles without catalytic converters.
