Mid-infrared Sensors Optical fibre sensor Carbon dioxide Sensors Diesel engine Exhaust Emissions

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 (NOx) or oxides of sulphur (SOx). The response of the sensor to carbon dioxide present in the exhaust of Fiat Croma diesel engine are presented.
