The Exhaust Resonator Explained

Feb 13, It may look like a muffler, but the resonators primary function is to take the sound waves created by the exhaust pulses and fine-tune them into a more organized pattern. While this helps improve power and efficiency, it also gives your vehicle its distinctive engine sound. Sep 21, Function of a Resonator A resonator installed as part of your car or trucks exhaust system serves one main purpose to resonate. Its sort of an echo chamber for your cars exhaust, preparing all of the loud noise coming from your engine for the muffler to silence it. But there is far more science to it than that.

When it comes to exhaust systems, many people know the basics. Things like the header, catalytic converter and muffler are all terms that you hear often but one that often goes unrecognized is the exhaust resonator. As engineers analyzed and improved exhaust systems, they realized there were advantages to be gained in organizing and controlling these pulses and came up with the concept for the resonator. Essentially it acts like a large echo chamber that takes the exhaust pulses and optimizes their frequencies to achieve better fuel efficiency and power production.

While this helps improve power and efficiency, it also gives your vehicle its distinctive engine sound. Whether you have a Dodge pickup or a Ferrari, many cars have their own signature sounds and it all comes from exhaust resonators. By tuning the pulses of exhaust gas to work together, it creates stronger waves of exhaust that vacuum the gas out more quickly. By manipulating the frequency of exhaust sound waves, it can either give your car a more throaty and loud tone or silence it for smooth peaceful driving.

Resonators are often times confused for mufflers and while they may appear similar and share some of the same jobs, they play an integral part in producing optimal volume and tone from your engine. They also have an important role in the exhaust evacuating process, which helps your engine produce how to assess gillick competence power and reduce fuel consumption at the same time.

The Resonator

Sep 29, You need a resonator to help control the sounds coming from your vehicles exhaust system to prevent it from being too loud or obnoxious. Your . Mar 27, Exhaust resonators are used to create smoother driving conditions, reduce noise from the engine exhaust and enhance engine performance. Exhaust resonators are add-on features within the exhaust system. The resonators are used primarily in combination with the muffler to reduce excessive exhaust noise. Feb 19, The Resonator When a wave hits the hole, part of it continues into the chamber and part of it is reflected. The wave travels through the chamber, hits the back wall of the muffler and bounces back out of the lovemeen.com: Karim Nice.

Internal combustion engines usually make a lot of noise while they are running, and this noise can be annoying and exhaustive to your ears, especially when it is heard for a long period of time. Thus, mufflers were created to reduce the noise generated by the exhaust system. Exhaust resonators, meanwhile, further reduce the noise by making sound waves that cancel noises out. A typical automotive exhaust resonator is made of a hollow steel cylindrical tube and is attached to the muffler of an exhaust system.

The sound can be enhanced by means of adjusting the exhaust note. Exhaust resonators are usually add-on features in exhaust systems.

They are placed together with the mufflers along the exhaust pipe and work primarily to decrease exhaust noise. The exhaust noise passes through the resonating chamber, which in turn tunes the sound to cause destructive interference in order to be canceled out by the opposite sound waves. Being an add-on device, exhaust resonators are provided by aftermarket manufacturers and can be installed on muffler systems of internal combustion systems, such as automobiles and motorcycles.

Some vehicles already are equipped with tuned exhaust systems with resonators, thus making the exhaust pipes capable of pulling the combustion products out of the chamber faster with reduced sound. Most aftermarket producers improve the exhaust tuners, as these help the vehicle perform more efficiently. Exhaust resonators provide a wide array of benefits to vehicle owners. Noise suppression also helps in passing fuel emission tests, as the resonator prevents chassis rattling, an effect that usually leads to contaminated fuel emissions.

Aside from exhaust resonators, catalytic converters also are part of the overall exhaust system to help the muffler perform its function of reducing exhaust noise. However, instead of canceling out each other's sound waves, their effect is to restrict the sound coming out of the exhaust pipe. Catalytic converters work hand in hand with exhaust resonators in reducing and suppressing engine noise, thus allowing the vehicle to achieve optimum engine and driving performance as compared with using mufflers alone.

Hailing from Arizona, William Hanz has been writing on a wide variety of subjects for nearly 2 years. His articles have appeared on several popular websites such as AssociatedContent. Hanz attended the University of Arizona majoring in computer science with a minor in English.
