What is the use of an exhaust silencer?

EI Williams designs custom built silencers including vent silencers, engine silencers, fan silencers and industrial silencers to meet all system requirements. We also have as part of our product line; thermal insulation blankets and industrial catalytic converters.

(firmenpresse) - The exhaust silencer plays an incredibly critical role to muffle the noise coming in the blasts inside a combustion engine .It's also used to cleanse the exhaust gases with the assist of a catalytic converter.



The exhaust design,as you might have noticed,features a bulge towards the end. The explanation behind making this bulge is usually to give a bigger cavity for the exhaust gases to flow,this mellows the sound coming directly in the engine and works around the principle of a Helmholtz resonator.



One other design sort, that my physics teacher taught me about ,includes splitting the exhaust stream into two with the help of a secondary channel emerging in the pipe after which reconnecting it back .the length of this secondary channel is such that when the two sound streams meet once again ,they are 180 degrees out of phase with respect to one another,this causes destructive interference at this junction! Therefore muffling the sound.



The catalytic converter catalyzes the redox reaction of ‘carbon monoxide-hydrocarbons’(ox) and ‘nitrogen oxides’(red) ,which basically assists in converting pollutants to significantly less dangerous gases.
