The Path Inside A Car Exhaust System
Your Car Exhaust System is more than just a piece of pipe under your car’s rear end with fumes billowing from it. It is actually a fairly complex system of mechanical and chemical filtration chambers that convert noxious gas by-products of fuel combustion into a less toxic exhaust.
A Closer Look At The Car Exhaust System
The entire vehicle exhaust system is a labyrinth of pipes and chambers underneath the car’s chassis. And in order to understand its processes better, let us follow the flow of a vehicle’s gaseous by-products as they travels through the entire exhaust system.
Flow Of Gases In The Car Exhaust System
The first component of a vehicle’s exhaust system is directly connected to the vehicle’s main combustion chamber, or the part of the engine where the fuel is burned. The ignited fuel gives off a cocktail of harmful gases (mainly carbon monoxide), and these gases are fed into the first sections of the exhaust system’s exhaust manifold.
The pipes of the exhaust manifold that are attached to the each cylinder head combines into a single pipe known as the main body of the exhaust, and the main body is where filtration systems and sensors like the oxygen sensor and catalytic converters are attached.
The oxygen sensor maximizes efficiency in fuel consumption by measure the amount of oxygen in the exhaust and adjusting the fuel mixture accordingly, while the catalytic converter can be one or more chambers that contain chemical and mechanical filtration media and convert poisonous gases into water vapour and carbon dioxide.
After the gas filtration, the exhaust passes through the muffler, or the component of the exhaust system that serves to muffle or dampen the sound produced by fuel ignition. Without mufflers, cars would be a common source of noise pollution.
The entire exhaust pipe ultimately ends at the tail pipe, or the length of pipe that you usually see protruding out the back of your vehicle.
