Method for producing a stream of hot combustion exhaust gases at a settable temperature, apparatus for carrying out the method and use of the combustion exhaust gases for the targeted ageing of catalysts
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（中）：

来自具有可变温度的含烃燃料的燃烧的废气流可以通过将废气分成两个单独的部分流，冷却一部分流，然后再次组合两个部分流来产生。 再次组合的废气流的温度可以通过相应的两部分流的节流来设定在含烃燃料的燃烧温度和冷却的废气部分流的温度之间 在他们再次聚集在一起之前。 以这种方式生产的废气流优选用于汽车尾气催化剂的限定老化。 在这种情况下，排气温度的变化对其空气/燃料比没有影响是特别有利的。
