mufflers -- designing

[Nishant_iitd09]

hi friends....
we are trying our best to design our own muffler this year. can u help us out in some respect. we are lacking in how to decide the density, radius of perforations in absorption muffler. i got report on this but, it is for 6 cylinder engine. i need it for 4 cylinder.

does the attenuation(transmission loss) depends on thickness of absorbing material, how we can decide it (parameters to decide).

length of muffler is an important task............we hav not got any proper information for this.

thanking in aticipation.

Nishant,

I am sorry I can not help you with the mufflers, but a lot of others already have. It is the second time you have started a tread on the same topic(designing mufflers for formula cars) in 2 months. Please do not do this it is absolutely not helping our cause, just read the Teams from India thread to know what I am talking about. You are from IIT D you have been around the forum long enough to know how it works.

Please take out this thread you have started and the other one that you have accidentally created. I really do not mean to be rude but please understand.

Thanks,
