Abstract: An exhaust aftertreatment filter is provided with localized and efficient heating for regeneration. Electrical and/or thermal conductors are wound with filter media sheets into a filter roll and/or conductors are provided at axial ends of the filter roll and/or microwave radiation is used for localized hot zone heating. Regeneration is provided at lateral slices of the filter roll lying in a plane extending transversely and radially relative to the filter roll axis.

Abstract: 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.
