N2 - A laser mass spectrometer (LAMS) for simultaneous detection of NO, NO 2, NH3 and other components (N2O, CO, O 2, H2O, aromatics) in the exhaust of combustion engines is presented. Its temporal resolution is in the 10 ms range. Comparison with non-dispersive IR, flame ionisation detection and chemical luminescence detection have been performed. Emissions of Otto and Diesel engines have been studied at different velocities, load and three sampling positions: in front of a catalytic pre-converter, in front and after the main catalytic converter. Finally, NO, CO, H2O, toluene and O2 were detected within the cylinder in dependence on the crank angle with a time resolution in the 10 ms range.
