Exhaust and Muffler Repairs Newcastle
The exhaust system has a fairly straightforward job on your car. For instance, it takes the burnt gas from the engine, and passes it through a filter (catalytic converter) to make it cleaner. Then, it shakes the gas all about in a can (muffler) to make it quieter. Simple right?
Well, sort of… Now let’s factor in the speed humps that wear or tear though the system, and the corrosion doing all its dirty work from the inside-out. Let’s also consider the sealing gaskets that endure a literal baptism of fire! OK, it’s a little less simple, but a lot easier to see how things go wrong.
So, if your car is starting to sound like the brass section of a primary school band, or if you’re concerned that harmful gas may be entering your car’s cabin, then why not book your exhaust and muffler repair with one of our fully qualified technicians at Green Bean Auto covering all of Newcastle, Lake Macquarie and surrounds?
Your exhaust. How does it work exactly?
The exhaust on your car helps to direct hot and harmful gasses from the engine by directing it to a safer location. Phew!
The system normally starts with robust pipes that attach to the engine, known as an exhaust manifold. This manifold helps to move the gasses from the engine and to absorb some of the high temperatures generated in your engine.
From there, the gasses flow through a filter known as the catalytic converter. This helps to minimise the harmful gasses from entering the atmosphere and thankfully, your car’s cabin too. The remainder of the exhaust system is made up of gaskets, hangers, piping and mufflers.
Your muffler. How does it work exactly?
These days, mufflers on cars are typically lightweight, thin-walled cylinders that are roughly the same size as the glovebox in your car. The job of a muffler is to quieten down the combustion process of your engine, reducing the overall volume (combustion noise). Before this happens, a resonator chamber first works to change the engine’s decibel (sound). The changing and softening of your engine’s noise allows for a more pleasant drive and keeps your neighbours happy too!
If you take a look inside a muffler, you’d likely find noise-muffling exhaust baffles, perforated holes that look similar to the side of a cheese-grater, and some fibreglass packing.
