What is emission system?

The emission system in a vehicle is responsible for reducing the harmful pollutants that are released into the atmosphere through the exhaust. This system helps to reduce emissions of nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter.

The emission system consists of several components, including the catalytic converter, oxygen sensor, exhaust gas recirculation (EGR) valve, and evaporative emission control system. The catalytic converter is used to convert harmful pollutants into less harmful gases before they are released into the environment. The oxygen sensor monitors the levels of oxygen in the exhaust gas to ensure the proper air/fuel mixture is being used. The EGR valve recirculates a portion of the exhaust gas back into the intake manifold to reduce emissions, while the evaporative emission control system captures and stores fuel vapors before they can escape into the atmosphere.

Regular maintenance and inspection of the emission system are important to ensure that your vehicle is meeting emission standards and is running efficiently. If you notice any issues such as decreased fuel efficiency, a rough idle, or the check engine light coming on, it is important to have your emission system checked by a professional mechanic. Failure to maintain the emission system can result in increased emissions, decreased fuel efficiency, and potential damage to other components of your vehicle.
