    摘要: A stream of exhaust gases from the combustion of hydrocarbon-containing fuels with a variable temperature can be produced by dividing the exhaust gases into two separate part-streams, cooling one part-stream and then combining the two part-streams again. The temperature of the exhaust-gas stream which has been combined again can be set to between the temperature of the combustion of the hydrocarbon-containing fuels and the temperature of the cooled exhaust-gas part-stream by corresponding throttling of the two part-streams before they are brought together again. The exhaust-gas stream produced in this way is preferably used for the defined ageing of automotive exhaust catalysts. In this context, it is particularly advantageous that the change in the temperature of the exhaust-gas stream has no influence on its air/fuel ratio.

    摘要: The invention relates to a method of determining activity and aging behavior of a catalyst. For this purpose, two independent substreams of combustion offgases are produced and mixed before coming into contact with the catalyst. The first substream of combustion offgases is preferably produced by burning a motor fuel and forms the major part of the combustion offgases. The second substream of combustion offgases is produced by means of a gas burner whose air ratio can be adjusted within a wide range. Mixing of this second substream of combustion offgases into the first substream enables the composition of the total stream to be set in a defined manner.
