In the context of steadily increasing legislative requirements for pollutant concentrations from combustion processes, especially in the automotive sector, the demands on measurement technology are also increasing. To ensure mobile monitoring of the regulated values, it is necessary to measure system parameters such as pressure, temperature, and pollutant concentrations non-intrusively with high accuracy, precision, and temporal resolution in real road operation. Tunable Diode Laser Absorption Spectroscopy (TDLAS) fulfills these requirements and additionally offers other advantages, such as an absolut and calibration-free measurement at comparatively low cost. The use of fiber-coupled diode lasers allows the application of compact measuring cells and thus the elimination of large and heavy attachments outside the measuring vehicles. Due to the modular design of the measurement systems, TDLAS also offers the possibility of integrating relevant pollutant components into the measurement chains in the future with little effort. This makes the method particularly suitable for investigating the exhaust gas composition of future synthetic fuels for pollutant components that have not yet been regulated.
