What exactly is the use of an exhaust silencer?


 
The exhaust silencer plays an extremely crucial part to muffle the noise coming from the blasts inside a combustion engine .It's also used to cleanse the exhaust gases using the help of a catalytic converter. Get far more information about industrial silencer
 
 
 
The exhaust design,as you might have noticed,has a bulge towards the end. The explanation behind creating this bulge is to provide a larger 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 ,involves splitting the exhaust stream into two with the assist of a secondary channel emerging from the pipe then reconnecting it back .the length of this secondary channel is such that when the two sound streams meet once more ,they are 180 degrees out of phase with respect to each other,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 aids in converting pollutants to less damaging gases.
