  • Patent number: 6938409
    Abstract: Exhaust gas amitted from a diesel engine flows through a ceramic soot filter in which particles contained in the exhaust are deposited and oxidized to regenerate the filter. The filter is regenerated by non-thermal, electric surface creeping discharge on filter surfaces covered with particles. In addition, nitrogen oxides may be reduced by selective catalytic reduction. The system is designed to ensure operation reliability and environmental compatibility.
