Vehicle exhaust gas abatement apparatus

A vehicle exhaust gas abatement apparatus comprising:

• an exhaust gas discharging unit having an exhaust gas discharging pass which is formed on one side thereof and along which an exhaust gas generated from an engine of a vehicle is discharged;
• a catalytic converter connected to a rear end of the exhaust gas discharging unit along a direction in which the exhaust gas is discharged and removing harmful components in the exhaust gas using a catalyst;
• and
• a fuel-type surface combustion unit coupled to one side of the exhaust gas discharging unit and configured to heat an inner portion of the exhaust gas discharging unit by heat of a flame via a fuel so that the exhaust gas is heated to an activation temperature or higher of the catalyst and then arrives at the catalytic converter,
• wherein the exhaust gas discharging unit includes:
• a discharging housing portion which has a pipe shape and forms a place where the fuel-type surface combustion unit is coupled;
• and
• an engine connection portion which is coupled to one side of the discharging housing portion and is connected to the engine;
• and
• wherein the fuel-type surface combustion unit includes:
• a unit body portion which is coupled to the discharging housing portion so as to surround the discharging housing portion in an open portion of the discharging housing portion and has an inner portion forming an empty space portion;
• a supply connector which includes a fuel supply unit for supplying a fuel and an air supply unit for supplying air to be mixed with the fuel and is coupled to the unit body portion to supply the fuel and the air to the space portion in the unit body portion;
• at least one distribution guide which is provided in the space portion in the unit body portion to distribute and guide the fuel and the air directed to the space portion;
• a surface combustion mat which is disposed in an opening portion of the unit body portion in contact with the discharging housing portion;
• and
• an ignition module which is provided on one side of the unit body portion and is configured to allow the surface combustion mat to ignite.
