Abstract: An exhaust system includes an electrically conductive shell defining an exhaust pathway. The shell includes a tapered portion that tapers inward toward a longitudinal axis of the shell to define a narrowing region of the exhaust pathway. The exhaust system further includes an ionization assembly and an electrical subsystem that applies an electrical potential difference between the shell and at least a portion of the ionization assembly located within the exhaust pathway. The ionization assembly includes a support arm located within the exhaust pathway that extends into the narrowing region of the exhaust pathway. The ionization assembly further includes a plurality of electrically conductive discs mounted on and supported by the support arm. The ionization assembly is electrically insulated from the shell by an electrically insulating support structure.
