Summary:

A new multicomponent exhaust gas analyzer has been applied to investigate the time-resolved concentrations of the aromatic hydrocarbon exhaust components benzene, toluene, xylene, trimethyl benzene under dynamic engine operation, such as sudden change of speed and load, misfiring and switching off the fuel mixture control.The analyzer consisting of a compact laser mass spectrometer is capable of measuring the concentrations of the individual aromatic hydrocarbon compounds simultaneously with 1 ppm sensitivity at a sampling rate of 50 Hz corresponding to a sampling period of 20 manuscriptHigh concentration peaks are observed for these substances at instationary motor operation. However, whereas the real-time concentrations of toluene, xylene, and trimethyl benzene show equal dependence on motor speed and load a different behavior has been observed for benzene even during the emission phase of single combustion cycles
