Component and System Level Study of DOC on CSF for Heavy Duty Applications - (ppt)

摘要

DOC on CSF technology provides the benefit of reduced packaging space, while enabling improvement in system NO_x conversion especially under low temperature cycles; The DOC on CSF functionalities are comparable to the CPT and SCRT systems; Active regeneration performance for this concept is not as good, due to the temperature gradient in the filter; a combination of passive and active regeneration can mitigate this challenge; DOC on CSF can be optimized to meet the specific requirements of the application.
