The Regeneration of Ceramic Diesel Exhaust Filters by Means of Surface Plasma
Abstract
The diesel engine is an energy-efficient power plant, but its exhaust emissions present a serious health and environmental problem. Drastic reductions of exhaust soot have been mandated throughout the world. Current control technologies, such as catalytic converters, alternative fuels, and advanced diesel engine combustion systems are only partially effective in controlling the soot generated from diesel engines. Exhaust filtration technology has to be deployed for effective soot control. Most of today's filter-based technologies, however, experience high operational back-pressures causing unfavorable fuel consumption. The key to the acceptability of barrier filters for diesel exhausts is the ability of the filter to be regenerated, or cleared of trapped particles, such that the exhaust back pressure remains low.
