Emission systems typically consist of a catalytic converter, a muffler, and an oxygen sensor. The catalytic converter helps to convert harmful pollutants into less harmful substances, while the muffler helps to reduce noise from the engine. The oxygen sensor helps to monitor the amount of oxygen in the exhaust gases and adjust the fuel mixture accordingly to reduce emissions.
Emission systems are an important part of protecting the environment and reducing air pollution. They help to ensure that vehicles and other sources of emissions are operating as efficiently as possible and are not releasing harmful pollutants into the atmosphere.
