Exhaust Service

September 20th, 2011

by: Mike Najjar

 

Whenever we talk about exhaust service, most people normally think about exhaust pipes and mufflers. Well, actually, exhaust service is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your vehicle manufacturer recommends you have your emission system checked out by a qualified St. Louis exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Master Auto Repair handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Master Auto Repair at call one of our shops to schedule an appointment if you experience these problems.

Let's review the exhaust system. We will start from the top and start with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose, or a gasket is leaking, dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and the environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. You will find this out when your car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away.

The exhaust system is attached to the car by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service covers plain old pipes and high-tech computers. It impacts everything from life and death safety due to exhaust leaks, to fine-tuning the sound of your ride.
