Car Exhaust Overview
Besides the tailpipe, there are several other important components that make up your car's exhaust that are not visible from the outside, including the exhaust manifold, downpipe, muffler, and catalytic converter. Keep reading to find out more about your car's exhaust system, what to look out for, and how to maintain it.
What Is the Exhaust System on a Car?
Located underneath your car, the exhaust system actually has three main functions, most of which are governed by laws in certain countries.
The first function is to carry away exhaust gases. The exhaust manifold collects exhaust gases from the engine's cylinders. The collected gases, which include toxic ones, are then converted by the catalytic converter into materials that are less harmful or non-harmful to the environment. The gases are subsequently channeled to the exhaust pipe, which releases them into the surrounding air. In some countries, the catalytic converter is required by law to be working properly so that the amount of pollutants released is minimal.
Second, because the collection and conversion of gases can be such a noisy process, the exhaust system is designed as a sound dampener. Your car's muffler, as its name implies, is integral to this step. The exhaust gases travel through the system and have their sound dampened by the muffler, which comprises perforated tubes, thus reducing the amount of noise leaving from the tailpipe. A well-functioning muffler is required in most countries to keep the level of noise pollution down.
Third, the exhaust system helps to increase your car's performance. If exhaust gases are left in the system, your car will have a harder time taking in oxygen to combust and generate power. The exhaust system therefore aids in increasing engine performance by enabling the engine to properly intake oxygen and expel the unwanted gases. The more effectively the engine performs, the more efficiently fuel is used, thus improving the fuel economy of your car as well.
Types of Car Exhaust Problems
For your safety, your budget, and your car's performance, it is in your best interest to keep your exhaust system running in optimal condition. The following signs can indicate a faulty exhaust system. If your vehicle is exhibiting any of them, it is time to take your car to a mechanic.
If you begin to experience an increase in engine noise. It could be a sign that there is a leak somewhere in the exhaust system, such as around the manifold or the joints.
Rattling / Vibrations
Excessive rattling and vibrations can be caused by several problems. One of the most common reasons is that there is a leak in the exhaust system. In such a case, the vibrations can be felt while driving, and worsen during acceleration.
Exhaust Smoke Colors
It is never a good sign if you see smoke coming out of your tailpipe, as it might point to problems outside the exhaust system.
Blue smoke usually indicates that there is excessive oil being burned by the engine as a result of worn-out valve seals, piston rings, or positive crankcase ventilation (PCV) valves.
Black smoke, on the other hand, is caused by too rich of an air-fuel mixture, likely due to issues with the fuel pressure regulator, air filter, and fuel injectors.
Finally, white smoke might be a sign that coolant and fuel are mixing. This can happen when the head gasket, which is responsible for keeping the two separate, fails or develops a leak.
If you notice smoke coming from your exhaust, we recommend having your car checked out immediately.
Unusual Exhaust Smells
The smell of gas is usually a telltale sign that there is a leak somewhere in your exhaust system, which is often paired with noise and vibrations. If you smell anything unusual, be sure to address the issue as soon as possible.
Decreased Power, Acceleration, and Fuel Efficiency
Because the exhaust system plays a part in increasing your engine's performance, a drop in power, acceleration, and fuel efficiency may signal that your engine has to work unnecessarily hard because there is a problem with the exhaust.
Car Exhaust Maintenance & Repairs
Cleaning your car's exhaust can help to prevent excessive buildup that can lead to rust and, subsequently, leakages. You can use soap and water to clean the exhaust tailpipe as far as you can reach to get rid of dirt and smoke deposits. Additionally, degreaser followed with metal polish can be applied to keep the tailpipe sparkling clean.
Your exhaust might need to be repaired if problems have already developed. Leaks in your exhaust can actually be repaired at home without welding if not too severe. Sealant-like products readily available on the market provide a solution that will save you the time and cost of bringing your vehicle to your local mechanic.
How to Prevent Catalytic Converter Theft
Your car's catalytic converter is an especially tempting target for thieves. This is because it contains precious metals such as platinum, palladium, and rhodium. Besides parking your vehicle in safe areas, you can ask your mechanic to have it secured to your vehicle.
How Long Do Car Exhausts Last?
The major parts in the exhaust system are designed to last the lifetime of your car. However, this is also largely dependent on the climate you live in. As with all systems in your vehicle, small problems can easily lead to larger, more expensive ones, so you should tackle them as early on as you can.
