What Is Exhaust? - What Is Your Car's Exhaust System?

What is Exhaust?

Your car's exhaust system is a complex, yet important part of your vehicle's mechanics. It's the mechanism that carries gases out of the engine and away from the passengers and the environment.

It's important that your exhaust is working properly, because a damaged or malfunctioning exhaust system can cause problems such as carbon monoxide poisoning and other health risks. Fortunately, you can identify some signs that your exhaust system is not functioning correctly and take steps to get it fixed or replaced as soon as possible. Let's take a closer look at automobileyes.com.

The exhaust manifold

A car's exhaust manifold is one of the most common parts of an exhaust system. It collects the incoming exhaust from all of the cylinders in a single pipe. Then it sends the gas to a catalytic converter, which analyzes the emissions and transforms them into less harmful substances, such as nitrogen dioxide or carbon dioxide.

The catalytic converter then sends the gases through the muffler, which reduces their volume and noise level. It also helps to reduce air resistance, which increases fuel efficiency.

Resonators

A resonator is another important component of an exhaust system that is often used to reduce the amount of noise produced by the engine. Resonators are usually tuned for a certain frequency, which is why they're commonly found on high-performance cars.

Headers

A header is a manifold that's specifically designed to scavenge the exhaust from the cylinders in your engine. The header's shape and length are carefully calculated to optimize the flow of the exhaust.

Generally, headers are made out of steel tubing that's joined at narrow angles to encourage the pressure waves produced by the scavenging to flow into the outlets of the header pipes and not back towards the cylinders.

It's a good idea to check your headers every so often, as they're the most likely place for exhaust leaks. If you see that the headers are starting to leak, they should be repaired or replaced immediately.

Muffler

The muffler is another important part of an exhaust system, but it's not as well-known. It's typically located at the rear of your vehicle, behind the tailpipe.

A muffler reduces the noise of the exhaust as it moves through the system, helping to make the various components of the exhaust work together more effectively. Increasing the size of a muffler can boost performance by making your engine sound more powerful, but be careful to keep in mind that the larger the muffler, the louder it sounds, and that some states require mufflers to be welded or otherwise secured to prevent leakage.

You should also be aware that if you are using a sportier exhaust system, it's likely to draw complaints from neighbors or even hefty fines from the authorities. It's also worth mentioning that some modified exhaust systems are illegal in some states, so it's important to check this before you purchase your next system.

The exhaust system is a complex piece of machinery, but it's one that can help your car function more efficiently and save you money on fuel. Keeping your exhaust system functioning correctly will improve its overall performance and safety, as well as help the environment by reducing greenhouse gas emissions.
