Patent
·
OSTI ID:5688248
A compact, sound-attenuating muffler is described for a high-performance internal combustion engine or the like including a casing having an inlet opening formed for the flow of exhaust gases into the casing and an outlet opening formed for the discharge of gases from the casing, and partition means positioned in and supported from the casing including a divergently tapered first partition formed to deflect gases toward side walls of the casing, and a convergently tapered second partition positioned in and supported from the casing downstream of the first partition and formed with central opening means therein for convergence of gases from the side walls to the opening. An improvement in the muffler consists of: the casing being formed with a transverse cross-section having a width dimension substantially greater than the height dimension; the first partition being an imperforate member formed to extend over the full height dimension of the casing and being formed to terminate short of the full width dimension of the casing to define a pair of openings proximate opposite side walls of the casing; and the second partition being formed to extend across both the width and height dimensions of the casing and being imperforate intermediate the casing walls except for the central opening means.
