Abstract

A 1999 Mercedes A170 CDI has been equipped with prototype NO_X 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 NO_X 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 NO_X adsorbers.
