Detection of Carbon Dioxide Emissions from a Land Transport Vehicle using a Mid-Infrared Optical Fibre Based Sensor

摘要

An optical fibre based exhaust gas sensor has been developed from low-cost mid-infrared components which is capable of detecting carbon dioxide (CO_2) 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 (H_2O), carbon monoxide (CO), oxides of nitrogen (NO_X) or oxides of sulphur (SO_X). Initial tests of this sensor on a modern diesel engine are outlined in this paper.
