DEVICE FOR REMEDIATING EMISSIONS AND METHOD OF MANUFACTURE

摘要

In at least one embodiment, a combined selective catalytic reduction catalyst and particulate filter (SCRF) includes a particulate filter having walls defining an intake channel including a downstream end cap and an outlet channel including an upstream end cap and an open end through which emissions pass. The walls define a plurality of pores. The walls include a plurality of zeolite-base metal particles and a binder. A washcoat is situated adjacent to less than 50% of the length of the outlet channel. The washcoat is capable of receiving noble metal particles.
