Vehicle three-way catalytic converter for collecting integrated particulate matters

The invention provides a vehicle three-way catalytic converter for collecting integrated particulate matters. The vehicle three-way catalytic converter comprises a housing and a carrier mounted in the housing, wherein the carrier is a wall-flow type honeycomb ceramic carrier, comprises axial ducts for allowing vehicle tail gas to pass through; one end of each duct is provided with a hole bottom for sealing the corresponding duct; the hole bottoms of adjacent ducts are separately positioned at different axial ends of the carrier; and the duct wall of each duct is infiltrated with a Pd coating and an Rh coating. According to the three-way catalytic converter provided by the invention, engine particulate pollutants also can be effectively collected while gas effluents HC, CO and NOX of engine tail gas are effectively reduced, so that exhaustion of the particulate pollutants is reduced; with the adoption of an external purifying technology, engine related hardware and an engine related system are not needed to be re-developed, so that unit vehicle cost is reduced; and compared with an independent three-way catalytic converter with a particle collecting device, back pressure of an exhaust gas post-treatment system is effectively reduced, so that the three-way catalytic converter is helpful for improving dynamic performances of the whole vehicle.
