Abstract
A 1999 Mercedes A170 CDI has been equipped with prototype NOX adsorber devices in order to study the impacts of regeneration conditions on the emissions reduction performance of the devices. This study consisted of a number of laboratory experiments utilizing a bottled-gas injection system to periodically provide fuel-rich exhaust conditions for device regeneration. The NOX adsorbers were evaluated on the LA4 driving cycle using a fixed regeneration schedule. The rich-pulse duration and minimum air/fuel ratio during the rich pulse were varied and the impacts upon pollutant emission rates measured. Results are presented for 5 prototype NOX adsorbers.
