Your question: Which is the device used in vehicles to reduce the pollutants in the exhaust?

A catalytic converter is a simple device that uses basic redox reactions to reduce the pollutants emitted from vehicles. It converts the harmful pollutants produced from the car engine into less harmful gases.

What pollutants are reduced from vehicle exhaust?

Over the past 30–40 years, vehicle tailpipe emissions of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HCs) have decreased significantly.

What pollutants are emitted by vehicles?

Vehicle pollutants harm our health and contain greenhouse gases that cause climate change. Burning gasoline and diesel fuel creates harmful byproducts like nitrogen dioxide, carbon monoxide, hydrocarbons, benzene, and formaldehyde. In addition, vehicles emit carbon dioxide, the most common greenhouse gas.

What is released from exhaust fumes?

The majority of vehicle exhaust emissions are composed of carbon dioxide, nitrogen, water vapor, and oxygen in unconsumed air. Carbon monoxide, unburned fuel, nitrogen oxides, and particulate matter such as mercury are also present in vehicle exhaust emissions in smaller quantities.
