Abstract
A system for reducing internal combustion engine emissions. The system includes an exhaust line for feeding an exhaust from an internal combustion engine to a catalytic converter and a particulate filter to produce a filtered exhaust. The system further includes a filter effluent line to feed this filtered exhaust to a tailpipe. The system further includes a bypass filtration system to receive the filtered exhaust and further filter the exhaust and return it to the filter effluent upstream of the tailpipe. The system further includes an ozone generator and a flow line to feed ozone to the bypass filtration system.
