Muffler: Muffler, device through which the exhaust gases from an internal-combustion engine are passed to attenuate (reduce) the airborne noise of the engine. To be efficient as a So that vehicle owners understand the importance of an exhaust system and the connected muffler, here is some basic information to explain the purpose of two main components, the Emissions Control System and the Catalytic Converter! The catalytic converter looks like a muffler and is located in the exhaust system in front of the muffler. Simply stated, hydrocarbons or carbon monoxide in the exhaust are converted to carbon dioxide and water as they pass over the catalyst. Heat is generated in the converter as it works to clean the exhaust. Muffler, also called silencer, device through which the exhaust gases from an internal-combustion engine are passed to attenuate (reduce) the airborne noise of the engine. To be efficient as a sound reducer, a muffler must decrease the velocity of the exhaust gases and either absorb sound waves or cancel them by interference with reflected waves coming from the same source. In the typical reactive design shown in the , the arrows indicate the flow of exhaust gas through a set of tubes and chambers inside the muffler. One important chamber is known as the Helmholtz resonator. This chamber is of a dimension carefully tuned to reflect and cancel sound waves of specified frequencies. Why is an Exhaust System and Muffler so important? If you need a new muffler or an inspection of your exhaust system, our Rum River mechanic will be happy to help you. 17 It is important to get the best-quality muffler to prevent engine exhaustion. Although there have been a lot of muffler choices available today, it is not that hard to spot the good ones. Just make sure that avoid imitation brands and only get those with OEM marks. More importantly, your car's exhaust system is never complete without a muffler to blow out these wastes out with. The muffler is basically a silencer or a device that reduces the noise of your car's exhaust system.

Also called a 'silencer', it helps tone down your engine's exhaust sounds to more aurally-pleasing notes. In the typical reactive design shown in the illustration, the arrows indicate the flow of exhaust gas through a set of tubes and chambers inside the muffler. One important chamber is known as the Helmholtz resonator. This chamber is of a dimension carefully tuned to reflect and cancel sound waves of specified frequencies. Query: how important are muffler
