TY - JOUR A1 - Kaspar, Marcel A1 - Rabl, Hans-Peter A1 - Mayer, Wolfgang T1 - Ion-Molecule Reaction for the Selective Detection of Hydrocarbons in Diesel Exhaust Gas T2 - Chemie Ingenieur Technik N2 - The hydrocarbons present in the diesel exhaust gas are analyzed. A mass spectrometer is used for the measurements, and it operates on the basis of an ion-molecule reaction. This method is especially suitable because it is selective, is as free of fragments as possible, and is highly sensitive to the species that need to be measured. The study shows that numerous hydrocarbons in diesel exhaust gas can be identified. In particular, three molecules, ethyne, ethene and propene, were analyzed online in-depth on an engine test bench under different engine operating conditions.
