Abstract:
An exhaust treatment apparatus and method for providing a controlled and well-timed feeding of supplemental oxygen to offset low oxygen content in exhaust flow passing over a desorbing hydrocarbon trap that previously accumulated hydrocarbons during a cold start cycle. Included is an ambient air injection system and associated control unit to offset the lacking oxygen level upstream of a reaction area for a downstream uf-HCT (preferably catalyzed with TWC material) with the exhaust placed in a lean state upon contact with the uf-HCT. An air injection embodiment makes use of preexisting vehicle components as to provide for a minimization of added components to a vehicle, while still addressing the need to clean-up exhaust emissions in an effort to satisfy stringent emission control requirements, such as those set forth in LEVIII.

Claim (Index 5):
The system of  claim 4  wherein the one or more upstream catalyst(s) includes at least one TWC close coupled catalyst.
