Abstract:
1. A muffler for attenuating acoustic pulses in a flow of exhaust gas from an internal combustion engine while simultaneously collecting soot, the muffler comprising: a plurality of disk pairs, each disk pair comprising a pair of self-propelled, rotatable coaxial disks, each disk pair positioned within a housing in a cascade configuration, the centers of each disk pair aligned with each other, and the plurality of disks structured to rotate about an axis of rotation defined along the aligned centers of the disks, each disk pair defining a radial workspace between them, the radial workspace having an axial feed port at the center of one of the disks and an axial extraction port at the center of the other disk; a baffle disposed between each disk pair, the respective baffles disposed between respective axial feed ports and axial extraction ports of each disk pair, the baffles and the disks structured to feed gas from each respective axial feed port, radially out from the axial feed port under the respective baffle and radially into the respective axial extraction port over the respective baffle, the gas exiting the workspace through each respective axial extraction port; vanes disposed on each disk and structured to drive each disk to rotate when the flow of gas across each disk engages the vanes; a housing disposed around the periphery of the plurality of workspaces such that soot advected out of the workspace impinges the housing; a soot collector for collecting the soot that impinges the housing; and a soot hopper for storing the soot.
