DEVICE FOR REPRODUCING A FOULING PHENOMENON OF A LINE CROSSED BY EXHAUST GASES PRODUCED BY A CONTROLLED IGNITION HEAT ENGINE

摘要

The invention relates to a device for reproducing a fouling phenomenon of a line crossed by the exhaust gases produced by a spark-ignition internal combustion engine, comprising a circuit (100) for circulation of gases, power supplies (11 , 12, 13, 14) in gas from this circuit (100) arranged to create the first part of a mixture representative of an exhaust gas, a first heater (15) of this first part of the mixture, an injection ( 16, 17) of liquid compounds arranged to complete the composition of the representative mixture placed downstream of the first heater (15), a heat exchanger (10) capable of cooling the representative mixture, seat of the formation of a fouling deposit, characterized in that it comprises a second heater (18) of the complete mixture representative of an exhaust gas placed upstream of the second heater (18) and in that the injection of liquid compounds (16, 17) comprises a injection of engine lubricating oil.
