Pollutants, including hydrocarbons, nitrogen dioxide, carbon monoxide, and others, are taken out of the motor before they may enter the atmosphere.
Engine operation triggers your exhaust system. The gases are formed as a result of the engine’s pressure and heat. The exhaust manifold is where the gases are combined with air after being forced there.
A catalytic converter then burns off the mixture. Through this method, dangerous contaminants are removed from the fumes and turned into safe substances.
The muffler is where the leftover gases are afterward forced to slow down and cool. The gas then leaves the vehicle through the exhaust.
