Abstract
A purification system of exhaust gases in an internal combustion engine purifies the exhaust gases by disposing a reaction furnace in an exhaust pipe of the internal combustion engine. The system includes a reactor including a honeycomb carrier having a plurality of carrier cells in the reaction furnace and plasma generating electrodes. On each of the plurality of carrier cells, a photocatalyst layer is coated. Further, the plasma generating electrodes, having a plurality of electrode cells, are mounted at an inner end and an outer end of the honeycomb carrier.

A purification system of exhaust gases in an internal combustion engine for purifying the exhaust gases by disposing a reaction furnace capable of reducing noxious components of the exhaust gases in an exhaust pipe of the internal combustion engine, the system comprising:
- a reactor including a honeycomb carrier having a plurality of carrier cells, on each of which a photocatalyst layer is coated, in the reaction furnace;
- and
- a plasma generating means having a plurality of electrode cells and mounted at an inner end and an outer end of the honeycomb carrier;
- wherein the honeycomb carrier includes a 3-way catalyst layer coated on a wall surface of each of the carrier cells and the photocatalyst layer is coated on the 3-way catalyst layer, the photocatalyst layer being activated by a plasma photic source.
A purification system of exhaust gases in an internal combustion engine for purifying the exhaust gases by disposing a reaction furnace capable of reducing noxious components of the exhaust gases in an exhaust pipe of the internal combustion engine, the system comprising:
