Abstract

A robust optical fibre based CO₂ exhaust gas sensor operating in the mid infrared spectral range is described. It is capable of detecting on board carbon dioxide (CO₂) emissions from both diesel and petrol engines. The optical fibre sensor is not cross sensitive to other gaseous species in the exhaust such as water vapour (H₂O), carbon monoxide (CO), oxides of nitrogen (NO_x) or oxides of sulphur (SO_x).The response of the sensor to carbon dioxide present in the exhaust of Fiat Croma diesel engine are presented.
