The Metropolis of Westminster and operator Veolia have ordered a retrofit of 92 Refuse Assortment Automobiles (RCVs) for the upcoming Extremely-low Emission Zone in London. As the primary Euro VI RCV fleet retrofit, the mixture of Amminex, a Faurecia firm (earlier submit), and Eminox know-how (earlier submit) has eliminated the blocking level for upgrading this automobile kind.
The retrofit order marks the primary time a fleet of RCVs will likely be upgraded to Euro VI equal ranges, and the Eminox/Amminex combo is thus far the one resolution having been authorised by the official Clear Car Retrofit Accreditation Scheme (CVRAS) for retrofitting RCVs.
The mix of utilizing ASDS strong ammonia know-how from Amminex and SCR catalyst know-how from Eminox has opened the door to addressing the emissions drawback even at very low exhaust temperatures on the difficult RCV drive cycle.
The 2 first demonstration autos have been on the highway for over a month. Our knowledge from the net NOxTracker device exhibits a mean NOx discount of greater than 94 % underneath extraordinarily tough driving circumstances. This might very nicely be probably the most difficult retrofit circumstances ever, and we’re proud to see the ASDS system delivering this wonderful efficiency.—Fabien Milanesi, Normal Supervisor of Amminex
The homologation standards in London are very formidable, and the check autos have confirmed the Eminox-Amminex partnership to be a aggressive resolution. Many cities throughout Europe are struggling to enhance air high quality, and the homologation knowledge from London present that there are not any technical arguments for slacking the RCV emission necessities.

The primary invention behind the Ammonia Storage and Supply System, ASDS, is the flexibility to soundly retailer reactive ammonia fuel in strong state by binding it to a salt referred to as AdAmmine. When heated, AdAmmine releases the fuel, which is then precisely dosed to the exhaust and SCR catalyst, thereby changing NOx to nitrogen and water. In comparison with typical liquid-based options, the usage of gaseous ammonia is a quantum leap in decreasing NOx emissions the place they damage probably the most: throughout sluggish, city driving in densely populated areas.
