Abstract
Fundamental regeneration rate data of cellular ceramic particulate traps are presented. The data were obtained from systematic bench experiments using scaled traps and simulated engine conditions. The study was conducted over a wide range of parameters, covering scaled regeneration flow rates from subidle engine flow to full flow at rated engine conditions, trap inlet temperatures from 500 to 650°C, oxygen concentrations from 5 to 21%, and particulate accumulation levels in the trap from a pressure drop ratio (relative to the clean unit) of 2 to 60. The effect of each parameter on the maximum trap temperature and regeneration time is independently studied and described. Favorable regeneration conditions in terms of minimizing the energy requirements for regeneration and avoiding trap destruction are identified. Finally, it is illustrated that regeneration maps of this type can be applied to develop a control logic for an automatic regeneration system.
