The technical reason for these high “off-cycle” NO x emissions is poor NO x conversion efficiency of installed SCR systems when exhaust temperature is low. A block of AdAmmine holds ~450g ammonia per liter solid for use in the NO x conversion. At low exhaust temperatures, catalyst activity also falls off sharply.
