Device for treating exhaust gases from a vehicle and a method to operate the same

A device for treating exhaust gas from a vehicle comprising:

• a chamber configured to allow at least one of burning and ionization of a plurality of combustible constituents present in the exhaust gas to pass through the chamber;
• a plurality of electrodes positioned in the chamber,
• each electrode comprises:
• a graphite core extending along a longitudinal axis:
• a ceramic insulation layer surrounding at least a portion of the graphite core;
• a copper sleeve disposed around the ceramic insulation,
• wherein a terminal portion of the graphite core extends beyond both the ceramic insulation and the copper sleeve, defining an exposed end configured for plasma discharge;
• and
• wherein each pair of the plurality of electrodes is positioned opposite to each other with a predetermined gap between each electrode of the pair plurality of electrodes,
• wherein the plurality of electrodes is arranged in a direction perpendicular to the direction of the exhaust gas flow, and
• wherein the plurality of electrodes is configured to generate a plurality of plasma arcs upon energizing the plurality of electrodes, wherein the plasma arc ionizes the exhaust gas to reduce emissions as the exhaust gas exits from a tail pipe of the vehicle thereby controlling the emissions of the vehicle;
• and
• a pulse controller electronically connected to the plurality of electrodes and configured to:
• step-up a predetermined voltage as an input voltage;
• control the time required for energization of one pair of electrodes of the plurality of electrodes at a time;
• and
• control duration of a plasma arc of the plurality of plasma arcs inside the chamber.
