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.
