Process for the catalytic purification of the Exhaust gases of cars with improved Cold starting behaviour.

摘要

An essential reduction of the Hydrocarbon emissions during Cold Start fuel of engines can be obtained.When before the exhaust gas Catalyst itself introduces an absorber of hydrocarbons in the Exhaust Duct.The Thermal capacity of the material and the choice of the proper conformation of the absorber is greater than the heat capacity of upstream Catalyst.
