A sensitive laser mass spectrometer has been developed for fast multicomponent automotive exhaust analyses. The system is particularly appropriate for working at dynamic motor test stands and provides the following features: This system has been used at a motor test facility to investigate the emissions of aromatic hydrocarbons benzene, toluene, xylene, and of nitrogen oxide in stationary and dynamic engine operation.These measurements demonstrate some of the capabilities of the analysis system to obtain fundamental information about the combustion processes and about processes in the exhaust pipe. This is essential for the development of the engine and engine control systems and other efforts to reduce emission of pollutants.
