Time-resolved chemical analysis by laser mass spectrometry: monitoring of in-cylinder and catalytic-converter processes of combustion engines

A laser mass spectrometer (LAMS) for simultaneous detection of NO, NO2, NH3 and other components (N2O, CO, O2, H2O, aroms.) in the exhaust of combustion engines is presented. Its temporal resoln. is in the 10 ms range. Comparison with non-dispersive IR, flame ionization detection and chem. 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 resoln. in the 10 ms range. [on SciFinder(R)]     «
