Professional Mechanic Explains How Exhaust Systems Work, Anchorage, Alaska

The exhaust system is a critical part of every automobile. Its function has a direct and noticeable effect on your car’s performance, including its power and fuel efficiency. However, since it is often located underneath the vehicle and is not regularly handled, it goes unnoticed by many. Here, the mechanics from Dean's Automotive Service Center in Anchorage, AK, lend insight into how the exhaust system works.

What Does the Exhaust System Do?

Your vehicle’s exhaust system has four primary functions: to direct exhaust gas away from the engine, to improve engine performance and fuel efficiency, to lessen the noise the engine makes, and to reduce harmful emissions. While stock exhausts are equipped to adequately perform each function, some drivers hire a mechanic to install aftermarket parts that deliver more power or produce a particular sound they prefer.

How Does It Perform Its Job?

mechanicA typical exhaust system is comprised of an exhaust manifold, an oxygen sensor, a catalytic converter, a muffler, and exhaust pipes. As your engine runs, it produces different gases that are carried from the cylinders by the exhaust manifold and funneled through the front pipe, away from the engine. These gases pass through the oxygen sensor, which calculates the amount of O2 in the exhaust and adjusts the air-to-fuel ratio. They are then directed to the catalytic converter, which turns harmful carbon monoxide and hydrocarbons into carbon dioxide and water vapor. The converted gas enters the muffler—which dampens the noise—before exiting through the tailpipe.
