... as three-way catalysts. However, ammonia slip may require removal on a dedicated catalyst called PGM Platinum group metal ammonia slip catalyst (ASC). The set consisting of the urea injection system, SCR and ASC requires control and on-board SCR Selective catalytic reduction diagnostic tools to ensure high...
