Fuel sulfur effects on diesel catalyst performance M.K. Khali Department of Emissions Research, Southwest Research Institute, PO Drawer 28510, San Antonio, Texas ABSTRACT Many improvements have been achieved in the design of modem diesel engines(Khair, GilM *2). These design improvements enabled the diesel engine to meet strict limitations imposed by emissions regulations adopted by many governments in the industrialized world. In spite of the success achieved in controlling diesel emissions while maintaining good performance characteristics, paniculate emissions still remain a challenge to researchers. Attempts to control diesel paniculate emissions led scientists to investigate diesel exhaust aftertreatment. Two methods of aftertreatment emerged as likely candidates for this task. The first method involved trapping and incinerating participates at certain intervals. This method used a diesel particulate trap(Garner^) with a regeneration system, and was quite
