AN APPARATUS FOR PREVENTING WHITE SMOKE OUTPUT FROM DIESEL ENGINE

摘要

PURPOSE: An smoke reduction device for controlling white lead emission from a diesel engine is provided to significantly reduce emission of white lead which is generated especially at the initial stage of a diesel engine-start in winter by limiting the ingredient ratio of diesel oxidation catalytic composition precious metals to a fixed ratio. CONSTITUTION: An smoke reduction device for controlling white lead emission from a diesel engine comprises a DOC(Diesel Oxidation Catalyst) and a DPF(Diesel Particulate Filter) which are mounted on the rear end of a diesel engine. The ratio of platinum to palladium mass(Pt/Pd) of diesel oxidation catalyst compositions which are applied to DOC is in the range of 0
