What is a catalytic converter?
A catalytic converter is a device that is installed in the exhaust system of an internal combustion engine. Its main function is to reduce the harmful emissions produced by the engine, such as carbon monoxide, nitrogen oxides, and hydrocarbons.
The catalytic converter works by converting these toxic gases into less harmful ones through a chemical reaction. This reaction takes place inside a honeycomb-like structure made of ceramic or metal coated with precious metals, such as platinum, palladium, and rhodium.
Catalytic converters have been a mandatory part of the exhaust systems in most vehicles since the 1970s. They play a crucial role in reducing air pollution and improving the air quality in urban areas.
A catalytic converter uses a process called catalysis to convert harmful gases into less toxic ones. As exhaust gases pass through the honeycomb structure of the converter, they come into contact with the precious metals coating. This interaction triggers a chemical reaction that breaks down the harmful compounds and transforms them into carbon dioxide, water vapor, and nitrogen gas.
The catalyst in a catalytic converter needs to be at a high temperature to effectively convert the exhaust gases. This is why catalytic converters are located close to the engine, where the exhaust gases are hottest.
Catalytic converters also require specific operating conditions to function correctly. One of these is a proper air-to-fuel ratio in the engine’s combustion process. If there is too much or too little oxygen present, the converter’s efficiency may decrease, leading to increased emissions.
In addition to reducing harmful emissions, catalytic converters also play a role in sound reduction. The honeycomb structure of the converter acts as a muffler and helps reduce engine noise.
Overall, catalytic converters are essential devices that have helped tremendously in reducing air pollution from vehicle exhausts. As technology continues to improve, catalytic converters are becoming more efficient and effective in their role. Additionally, various advancements have been made to make them more durable and long-lasting. With stricter emission regulations being implemented worldwide, the demand for better catalytic converters is only going to increase in the future [1].
