AVL SESAM FTIRSESAM FTIR Multicomponent Exhaust Gas Measurement System
AVL SESAM (System for Emission Sampling And Measurement) is a series of multicomponent exhaust gas measurement systems that are used particularly in the development of modern engines and vehicles in order to achieve compliance with current and future exhaust gas legislation. FTIR (Fourier Transform Infrared Spectroscopy) is an optical measurement method that can diagnose a large number of different exhaust gas components simultaneously. By means of absorption of infrared light by the individual gas components, up to 25 gases can be measured simultaneously and absolutely synchronously. In addition, some collective components can be calculated from this process. The application of this measurement principle has successfully proven itself in the automotive industry over many years and SESAM FTIR systems have established themselves as the clear world market leader. The latest generation, the AVL SESAM FTIR Version 4 is now available.
Applications- General exhaust gas measurement tasks on engine and chassis dynamometer test beds
- Online exhaust gas evaluations in steady-state and transient engine operation (modal analyses)
- R&D and ECU calibration for low-emission gasoline engines with catalytic converters, NOx storage catalytic converters
- R&D and ECU calibration for low-emission diesel engines with catalytic converters, NOx storage or SCR catalytic converters, diesel particle filters
- Hybrid drives
- Fuel cells
