Important Things You Need to Know About Your Car Exhaust

The exhaust system is far more important than many people give it credit for. Did you realize that it has everything to do with how fuel efficient your vehicle is? Not to mention it plays a role in your safety as well as in protecting the environment from harmful emissions.

In the combustion chamber, air and fuel are burned creating gases and the exhaust carries these emissions away. There are various parts to the system including the catalytic converter, the exhaust manifold, the muffler, exhaust pipe, and the oxygen sensor. If even one of these is failing then your car may be dangerous to you (the environment, and your wallet).

Bad Vibrations

Has your car started shaking inexplicably? A suddenly vibrating vehicle could be an indication of an exhaust problem. You might have a leak if your gas pedal and/or steering wheel are shaking, but if the leak is big enough the entire car might shudder. This isn’t just a risk to your car it can also impact your ability to steer and control your vehicle safely.

If your car is vibrating then make an appointment with a reputable mechanic immediately.

Loud Noises

Can you hear knocking? Clunking? Wheezing? Whispering? If your car is suddenly making loud noises you’ve never heard before then you could be in trouble. Part of the exhaust system’s role is keeping your vehicle running quietly, so if there is suddenly lots of engine noise the problem is likely somewhere in the exhaust. The system has many joints that are susceptible to leaks.

Remember, the harmful fumes that the exhaust carries away are harmful to your health and if they aren’t being disposed of properly they could be leaking into the cabin of the vehicle which is exposing you to harmful chemicals.

A Drop in Fuel Efficiency

Have you noticed your tank isn’t lasting you as long? Are you suddenly in need of gas far sooner than you normally would be even though you haven’t changed your driving routine? While there could be a plethora of reasons for this, one of the most common reasons for this lies in your exhaust system. When the exhaust is faulty it allows the gases to stay which causes the engine to run hotter thus burning your fuel quicker.

A Cloud of Smoke

Your car can puff out a wide variety of colored smokes, but do you know what they mean?

White – If the smoke is thin then you have nothing to worry about, however, if it’s thick it could indicate that your engine is overheating, that the engine block is cracked or that the head gasket is blown.

Grey – Your issue may lie in the transmission.

Blue – Indicates that you’re burning oil or that oil is leaking into the combustion chamber.

Black – This could be a sign of a few different issues. While it could indicate that your air filter is clogged or that your engine is burnt it may also mean there’s an issue with your fuel injectors, fuel pressure regulator or sensors.
