Abstract

Online detection of harmful exhaust gases is necessary for optimal engine control to reduce the polluting emissions of diesel cars. Optical detection methods in the UV-VIS range enable the simultaneous characterisation of various gases such as NO, NO₂ and SO₂. Additionally this technique is fast and has a low cross-sensitivity to other exhaust components. First results show the advantages for the optical approach compared with standard electrochemical gas sensors.
