The positioning of the temperature sensors in the sampling system, as well as in the integrated FTIR-analyser, has been carefully chosen to give a fast and accurate temperature reading of the sample flow. This also improves the accuracy of the system when measuring transient processes in the exhaust flow. The filter box has a heated stainless steel particulate filter (1μ) to protect and ensure the optical efficiency of the FTIR analyser. The filter box is available with 2 or 4 channels, which allows sampling from different points of the exhaust gas after-treatment system.

Areas of application
To meet regulations such as EURO VI and EPA 1065 exhaust gas after-treatment systems have become increasingly complex. The introduction of SCR catalysts for diesel engines and the growing interest in alternative fuels, have contributed to make them even more complex. The MEGA-5 system is capable of fast and accurate measurements of all exhaust gas components in compliance with EURO VI and EPA 1065 regulations. Typical applications of the system:

• R&D of heavy duty engines with SCR
• Measurements of ammonia (NH3) for certification purposes
• R&D of catalysts such as SCR, DOC and LNT
• Alternative fuels (Bio-Diesel, Ethanol, Methanol, etc.)
• On-vehicle measurements and data acquisition.
