Abstract

This paper describes an optical fibre sensor for the detection of NO_x (NO₂ and NO) and CO₂ in the exhaust system of a road vehicle. The measurement is based on a free path interaction zone which is interrogated using UV and NIR light guiding optical fibres and collimated lenses. Results are presented in the absorption spectra of the gases in the UV region for the NO_x gases and NIR region for CO₂. These demonstrate that using this method it is feasible to identify the individual CO₂, NO and NO₂ species as well as other gases in the exhaust system. Measurement of concentrations to the level of ten’s parts per million (ppm) have been demonstrated for the NO_x gases.
