In the ongoing quest for reduced-emission powertrains, exhaust gas aftertreatment systems are becoming increasingly complex. The introduction of dual stage SCR catalyst systems and the increased use of alternative fuels has heightened this complexity. In order to manage and reduce pollutants and emissions, a clear understanding is required of aftertreatment systems and the exhaust gas components involved. With the AVL SESAM i60 FT SII, we have created a tool that supports the user in gaining that knowledge for the following applications:
R&D and certification of modern heavy-duty engines with SCR technologies (Euro IV, V and VI), especially for the measurement of ammonia (NH3)
R&D and certification of all modern light-duty diesel engines with exhaust after treatment systems, e.g. for the measurement of N2O
General purpose exhaust emission measurement on engine and chassis dynamometer test cells
R&D of modern exhaust after treatment systems such as those featuring (Diesel Oxidation Catalyst (DOC), Selective Catalyst Reduction (SCR), Lean NOX Trap (LNT) .
Development and application of alternative fuels (H2, NH3, CNG, ethanol, methanol, bio-diesel, etc.)
R&D of various other applications such as fuel cells and hybrid drives
Thanks to the iGEM SESAM touchscreen control software, operation is easy and intuitive. Bench status, including all streams and analyzers can be viewed at a glance. The system provides legislation compliant support for Euro VI and EPA 40 CFR part 1065, including automated compliancy checks. Diagnostic functions can be performed automatically, which supports troubleshooting down to the sensor and valve level. The SESAM i60 FT SII is incredibly flexible making integration into your existing testbed automation system fast and painless thus adding to the value of this dynamic, high-end measurement system.

SESAM i60 FT SII Small
The small SESAM i60 FT SII cabinet includes the FTIR i60 spectrometer, optionally an FID analyzer for THC measurements, and a PMD analyzer for O2 measurements.
SESAM i60 FT SII Large / Dual
The large cabinet may contain an additional PMD analyzer for O2 measurements and/or an IRD analyzer for CO2 EGR 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.
SESAM i60 FT C
This is a streamlined version of the SESAM i60 FT SII for the measurement of the most important exhaust gas components when applying SCR exhaust after-treatment systems.
