Abstract
Today exhaust gas aftertreatment is based upon traditional catalysis equipping many vehicles around the world. But researchers concentrate on clean emissions systems using electrical discharges of Barrier or Corona types (Plasma aftertreatment) as one considers the recent works of Prof. S.Zhdanok of CTP Institute in Minsk, Belarus. As the results of these works prove to be encouraging, ECIA Company, as worldwide exhaust systems supplier, took an interest in doing some measurements to get its own opinion in real environmental conditions being far more severe than those usually met in labs. These works just tend to put in a prominent position and to determine the real potentiality of perspectives given by Plasma phenomena.
