Tell me about after treatment system.

Question

Accepted Answer

An after treatment system is a system used to reduce emissions from exhaust gases.

After treatment systems are commonly used in vehicles to reduce harmful pollutants in exhaust gases.
These systems typically include components such as catalytic converters, diesel particulate filters, and selective catalytic reduction systems.
The purpose of an after treatment system is to treat the exhaust gases after they leave the engine, reducing pollutants before they are released into the environment.
For example, a diesel particulate filter can trap and remove soot particles from diesel engine exhaust, while a catalytic converter can convert harmful gases like carbon monoxide and nitrogen oxides into less harmful substances.
After treatment systems are important for meeting emissions regulations and improving air quality.
