Abstract

A multispecies near-infrared diode laser spectrometer has been constructed for measurements of carbon monoxide, carbon dioxide, and methane directly in the exhaust of a static internal combustion engine. A wavelength modulation-division multiplexing scheme was implemented for the two distributed feedback diode lasers. Gas concentration variations were observed for changes in operating conditions such as increasing and decreasing the throttle, adjusting the air–fuel ratio, and engine start-up.

(a) Line strength spectra of CO and CO 2 near 1580   nm taken from the HITRAN 2000 database. The lower spectrum is an expanded part of the same spectrum showing the two selected transitions: the P(5) transition of the second overtone of CO at 1579 .737   nm ( 6330 .168   cm 1 ) and the P ( 20 ) ( 0 , 0 , 0 ) to ( 2 , 2 , 1 ) transition of CO 2 at 1579.574   nm   ( 6330 .821   cm 1 ) . (b) Typical second-harmonic wavelength modulated spectra of the two CO and CO 2 absorptions. Note that the scale is opposite the spectra in (a) in the direction of increasing wavelength.
