ABSTRACT:
A remote gas analyzer for motor vehicle exhaust emission surveillance in which a planar array of gas analyzer beams intersects substantially an entire cross-sectional segment of an exhaust gas plume in order to determine the volume concentration of gas pollutants in the exhaust. In a further variation using more readily available equipment to detect the less prevalent pollutants, the planar array determines the change in amount per unit volume of a first pollutant emitted by a motor vehicle passing the array. The first pollutant having a relatively high and more easily detectable concentration. A second, multi-spectral gas analyzer beam intersects the exhaust to determine the change in concentration of the less prevalent pollutants with respect to ambient, and also determines the change in concentration of the first pollutant. The ratio of the change in the first pollutant's weight per unit volume to its change in concentration as determined by the second analyzer is used to determine the change in the amount per unit volume of the remaining pollutants.
