    摘要: Gas treatment systems are described that allow for modular development of gas treatment systems, for example exhaust gas aftertreatment systems, using generally standardized parts. A number of subsections are provided, including a treatment subsection containing an exhaust gas treatment device for treating exhaust gas. The treatment subsection is designed to be connectable to an inlet subsection, an outlet subsection, or other subsections in a manner that allows the positions, both longitudinally and rotationally, of the treatment subsection relative to adjacent subsections to be adjusted as required during assembly. This permits an infinite number of length and/or clocking configurations for the aftertreatment system to be manufactured.

    摘要: An active silencer for a vehicle exhaust system that has a low profile so that it can be hung underneath the vehicle in a conventional manner without altering the vehicle. The silencer has a chamber isolated from the exhaust flow in which one or more speakers are mounted side-by-side. The speakers face downwards and share a common tuning chamber within the isolated chamber. The tuning chamber is ported to a mixing chamber where the canceling acoustic waves mix with noise from the exhaust flow before the exhaust noise exits to the atmosphere.
