The sophisticated control software iGEM SESAM is based on the iGEM software platform. The iGEM SESAM software allows for easy, intuitive operation via a touchscreen and provides a quick overview of the system status. It includes diagnostic functions and checks to be performed automatically via the integrated calendar function. / 167 MULTI-COMPONENT EXHAUST MEASUREMENT SYSTEM AVL SESAM i60 FT SII BENEFITS AT A GLANCE • Optimized evaluation methods and gas cell for up to three times better detection limits of 5 Hz (e.g. NH3, N2O) • 35% faster response times at lower sample flow rates (≤ 1.5 s at 8 l/min) • Extended life time of key components like detector and laser (over 4 years) • Self-aligned gas cell with robust and service optimized design • Reduction and ease of maintenance and repairs The SESAM i60 FT SII provides accurate and fast measurement of the most important exhaust gas components for all automotive applications within one system. The revised, intuitive and interactive user interface supports all essential operation, service and diagnostic functions and issues warnings in case of pending maintenance intervals. The Quality Center iQ makes it possible to monitor freely selectable variables (e.g. pressures) and visualizes the statistical evaluations of calibration and check data. MEASUREMENT PRINCIPLE The system is available in two cabinet versions, which allow for various standard setups and the integration of different extensions. The small cabinet includes the FTIR i60 spectrometer and optionally an FID analyzer for THC measurements. The large cabinet may also contain an additional PMD analyzer for O2 and/or an IRD analyzer for EGR (CO2) measurements. Alternatively, the large cabinet can be equipped with two FTIR i60 spectrometers for dual stream applications providing simultaneous pre- and post-exhaust aftertreatment measurements. APPLICATION Today’s exhaust gas aftertreatment systems for combustion engines are getting more and more complex, especially since the introduction of SCR catalysts and the increased use of alternative fuels. Understanding the detailed chemical reactions in engine exhaust and aftertreatment systems is critical for the efficient development of new engines and powertrains. The SESAM i60 FT SII guarantees best quality measurement results and complies with legislative requirements such as Euro VI and EPA 40 CFR part 1065 and 1066 for measurements allowing FTIR.
