Abstract
The invention provides a filter system, a regeneration system, a combined soot-removing system and applications for the systems. The filter system may act as a purifier and a muffler for heavy and light duty diesel vehicles. The invention is a unique dual pass filter system that removes particulates and nitrogen oxides in successive passes before the gas exits the filter. The regeneration system includes an electric-powered heat source for safety and better control of the regeneration process. A motor vehicle application is also disclosed.
