Abstract
A white smoke reduction system for a diesel vehicle reduces white smoke generated from a diesel vehicle. The white smoke reduction system includes a diesel oxidation catalyst (DOC) mounted on an exhaust line connected to an engine to oxidize exhaust gas through a catalyst. A filter module is connected to a rear end of the DOC to collect particulate matter contained in the exhaust gas and is coated with a ceria (CeO2) ingredient such that sulfur oxide is separated at a temperature equal to or more than 600° C.
