What Is The Purpose Of A Vehicle Exhaust System?

Your vehicle’s exhaust system does a lot more than you might think it does. Trojan Auto Care is a full-service automotive shop, and this includes exhaust system repair and replacement, but what does the exhaust system really do? Let’s talk about this crucial automotive system and why you’ll never want to run the risk of allowing it to breakdown.

Vehicle Exhaust System Parts

The exhaust system removes the gases a combustion engine produces so you aren’t poisoned by them. This is the most crucial job of the exhaust system: protection. The exhaust system also muffles your engine’s noise and helps your engine run efficiently. The latter saves you money at the pump, which is an added benefit. The primary parts that make up your vehicle’s exhaust system include the

  • Catalytic Converter
  • Exhaust Manifold
  • Exhaust Pipe
  • Muffler
  • Oxygen Sensor

Basically, the exhaust manifold gathers the exhaust from each cylinder and pushes it into the exhaust pipe. The oxygen sensor measures the amount of oxygen in the exhaust and adjusts fuel delivery when necessary. The exhaust then flows through the catalytic converter to switch dangerous gases into carbon dioxide and water vapor. All the while, the muffler keeps everything quiet.

Let’s Break This Down a Little Further

Your car, truck, or UV’s engine needs a constant flow of oxygen and fuel to run efficiently. As exhaust builds up inside the combustion chamber, there’s no room for fresh oxygen, and your engine’s performance suffers. The exhaust system allows the circulation of fresh oxygen into the engine to keep the combustion (firing) going by removing the exhaust created by – you guessed it – the combustion.

Consequently, if there is a problem within the exhaust system, your vehicle’s performance will suffer. For example, if you have a muffler hole, you will hear the loud noises engine exhaust makes as it exits the vehicle. If your catalytic converter is clogged, exhaust will back up into the system. A failing oxygen sensor can make incorrect air-to-fuel ratio adjustments and this, too, will affect engine performance.

Anything that prevents fresh oxygen from getting into the engine will force your engine to work harder. It will struggle to keep the combustion going the exhaust is not expelled. The result could be a rich air/fuel mixture that will make your automobile stutter, surge, and even stall when flooded. You might also see black smoke coming out the exhaust pipe and your gas mileage will tank – no pun intended.
