Title
(EN) ACOUSTIC VOLUME IN HOT-END OF EXHAUST SYSTEMS
(ZH) 排气系统热端的声容积
Abstract
(EN)
A vehicle exhaust system includes a component housing defining an internal cavity, a first exhaust gas treatment element positioned within the internal cavity, a second exhaust gas treatment element positioned within the internal cavity and axially spaced from the first exhaust gas treatment element by a gap, and a resonator volume in communication with the internal cavity.

(ZH)
