摘要：
A method of measuring oxygen-containing nitrogen components including nitrogen dioxide in exhaust gases of internal combustion engines, wherein an exhaust gas sample is taken from a removal point 10 at the exhaust gas pipe 1 and is guided to at least one measuring instrument by means of a removal line, wherein, for the purpose of measuring the oxygen-containing nitrogen components, there are provided a separate removal point 10 and a removal line 11 and that the exhaust gas sample for measuring the oxygen-containing nitrogen components is set to a temperature at which a reaction between the nitrogen dioxide and soot is low.
