Exhaust system of harmful exhaust gas reduction type automobile

摘要

The present invention relates to an exhaust apparatus for an automobile, and more particularly, to an exhaust apparatus for an automobile, which effectively removes nitrogen oxide components that are difficult to purge, which are discharged from an oxidizing atmosphere by using a photocatalyst, and stores a noble metal or nitrogen oxide adsorber, The present invention has been made to solve the above problems, and it is an object of the present invention to provide a ventilation system for a harmful exhaust gas-reducing automobile which can significantly reduce facility cost for air pollution prevention as well as air pollution. In order to achieve the above object, the present invention provides a plasma processing apparatus comprising: a plasma reactor installed at an intermediate portion of an exhaust pipe; A power supply for supplying power to the plasma reactor; An engine control unit for controlling power supply of the power supply; A photocatalytic reactor located inside the plasma reactor and purifying a nitrogen oxide component that is discharged together with a large amount of oxygen in the exhaust gas in an oxidizing atmosphere; and a photocatalytic reactor positioned inside the plasma reactor to remove unburned hydrocarbons, carbon monoxide And a three-way catalytic reactor for purifying the components.
