When a car engine runs, it produces heat as it burns fuel to create power. This heat needs to be managed and released, otherwise it can cause wear and tear on engine parts and decrease the car's performance.
The exhaust system is designed to manage this heat. It collects the hot gases that are created during combustion and channels them out of the engine and into the atmosphere.
There are three main parts to an exhaust system: the manifold, the catalytic converter, and the muffler.
The manifold is where the hot exhaust gases first enter the system. It connects to each of the engine's cylinders and collects the gases as they exit.
The catalytic converter is the next part of the exhaust system. It's responsible for breaking down harmful chemicals in the exhaust, like carbon monoxide and nitrogen oxides, and turning them into less harmful gases like carbon dioxide.
Finally, the muffler is where the exhaust gases exit the car and are released into the atmosphere. The muffler's job is to reduce the noise created by the exhaust as it exits the car.
Overall, the exhaust system is essential to keeping a car running smoothly. Without it, the car would run hot and loud, and be harmful to the environment.
