HNO2, NO2 and NO Measurements in Automobile Engine Exhaust by Optical Absorption

  • Conference paper
Monitoring of Gaseous Pollutants by Tunable Diode Lasers

Part of the book series: Air Pollution Research Reports ((APRR))

Summary

Exhaust gases of automobile engines (Diesel- and spark ignition types) were analyzed for nitrogen compounds (NO, NO2, HNO2, and CH3 ONO), SO2 and CH2O by differential optical absorption spectroscopy (DOAS). Detection limits of the technique ranged from 0.1 to 2.2ppm at absorption path lengths of 0.15 to 1.5m. Maximum HNO2 concentrations were reached at medium load operations and ranged from 0.15% to 3% of total NOX emitted for spark ignition and Diesel- engines, respectively.
