Abstract: For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO₂, NO, NO₂ and N₂O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation coefficients connected with the reproducibility is lower than 6% for small amounts. The device has been evaluated on a bench engine and shows similar results with common analysers, and in addition, other compounds have been identified.
