Abstract
An exhaust silencer for an agricultural tractor having a diesel engine with a cylinder capacity 2.5 to 4 liters and developing a power of 50 to 75 HP has a cylindrical body of elliptical cross-section which is closed at each end by an end-wall and is subdivided internally into two resonance chambers and two gas expansion chambers by three dished baffle-plates, the third baffle-plate having two tubular ducts. To optimize the acoustic performance specific dimensions of the chambers, of the ducts, of a perforated induction pipe and of an outlet pipe are prescribed.
