PURPOSE: An air purifier is provided, which can purify air pollutants released from automobiles by photocatalyst layer impregnated coated with photocatalyst material and is exited by an ultraviolet wave lamp that is attached to a radiator, a condenser and a filter of a fan in an automobile. The purifier is free from the purifying capacity due to travel of automobile because the purification efficiency is improved by extended travel. CONSTITUTION: The system comprises the followings: (i) a photocatalyst material coated on a heat exchanger of an automobile, the heat exchanger being a radiator with a cooling fan (12) and many fins in which fluid coming from the internal-combustion engine flow; and (ii) a light source for exciting a photocatalyst material, the contaminated air passing through the heater and being purified by photocatalyst. |
