As one of the most vital systems of your vehicle, the exhaust system is responsible for no less than your engine's toxic gas emissions. Primarily, this system conducts the transmission of all the burnt gases coming from your internal combustion engine down to the exhaust pipes. If these waste gases don't exit your engine immediately, then your engine could risk choking up and breaking down. Aside from this main function, your exhaust system also features the muffler, which is tasked to reduce the noise generated by the engine.
The muffler's the part that hosts this dampening stage of the emission process, and is composed of metal plates and tubes. Consider this your exhaust system's silencer. Without it, your engine's going to create quite a racket. This silencing device is often located along the exhaust pipe system underneath your vehicle, which stretches all the way to the rear until the tailpipe. In freighter trucks, this is vertically mounted behind the cab, but serves the same purpose of damping the tremendous amount of noise coming from the engine.
Being a silencing device, the muffler requires a complex mechanism to get the job done. This includes the use of a backbox, which is designed mainly to receive the pressure waves. These waves then bounce around the cylinders inside the chamber called the resonator, then through one or more tailpipes. The process of wave collision within a truck or car muffler allows for waves of equal but opposite amplitude to cancel each other out. This destructive interference is the muffler's way of conducting noise reduction.
With most of the exhaust system's parts located in the undercarriage, the muffler's condition is often neglected along with the pipes. These parts are vulnerable to excessive surface damage brought by rust, grime, and road impact, and may soon begin to manifest signs of wear. Compared to pipes, damage to mufflers should be relatively easier to detect due to obviously altered noise emissions. Aside from that, a faulty exhaust system can cause any vehicle to fail the state-required smog tests. For any car or truck owner, it should be customary to take a peek at your undercarriage from time to time to make sure there are no visible threats to your exhaust system. Keep your eyes, ears, and nose open for anything unusual about your emissions.
