Abstract

An exhaust silencer for a railway locomotive with a supercharged, six-cylinder diesel engine developing a power of about 200-250 HP has a cylindrical body closed at each end by an end wall and subdivided into three resonance chambers and three gas expansion chambers by five dished baffle-plates, the fourth and fifth baffle-plates each having four tube sections. To optimize the acoustic performance specific dimensions of the chambers, of the tube sections, of a perforated induction pipe and of an outlet pipe are prescribed.
