Abstract
The present invention provides an electrically stimulated catalytic converter for treating engine exhaust from a vehicle engine. The electrically stimulated catalytic converter includes an exhaust conduit having one end thereof adapted to be connected to an exhaust pipe, and the other end thereof opened to the atmosphere outside the vehicle or connected to a reduced-size catalytic converter; and a corona charger apparatus operatively connected to the exhaust conduit. The corona charger apparatus is housed with a housing unit disposed between the ends the exhaust conduit. The corona charger is intrusively or non-intrusively associated with a main flow path defined by the exhaust conduit. The corona charger includes at least one electrode which may be recessed away from the main flow path. A plurality of corona chargers may be used in various combinations. The electrically stimulated catalytic converter is adapted to reduce exhaust pollution.
