From The Engine To The Tailpipe

We all know what an internal combustion engine does right? Simply put, it burns fuel in a closed chamber to generate the power needed to either drive a vehicle or just to make a lot of noise. But what happens to the fuel when it is burned. Of course, combustion involves chemical change and that means a new substance is formed from the liquid fuel. That is what we call the engine's emission right? Now, what happens to that gas on its journey from the combustion chamber to the tailpipe where it is expelled to the atmosphere?
Let us take a tour inside a vehicle's exhaust system shall we? Typically, the emission of the engine will pass through a catalytic converter, a muffler, yeah, like your Mercedes-Benz muffler dude, and if you own a turbocharged vehicle, emission will also pass through the turbocharger.
From the engine, the exhaust gases will be collected by the exhaust manifold or called the header. An exhaust manifold is connected to the engine with a pipe fused to different cylinders, the gases from all cylinders are then passed through a single pipe connecting all the other entry pipes of the manifold.
The turbochargers on vehicles are powered by the onrushing exhaust gas. The exhaust gas powers a turbine which generates pressurized air which will be fed to the engine for better performance. Turbochargers are found in the exhaust system because it drew power from exhaust gas, that is definitely clear.
Catalytic converters meanwhile are placed in the exhausts system to clean out the engine's exhaust. The cat con does this by forcing exhaust gases to react with elements embedded on the device. Once the exhaust gas reacted with the elements of the catalytic converter, it becomes cleaner. The gas then passes through to the muffler.
The muffler's job is to reduce the noise of the escaping exhaust gas. it is designed to make sure that the sound made by the onrushing exhaust gas will be cancelled out.
