ABSTRACT:
An exhaust emission control apparatus for treating the exhaust of an internal combustion engine by a combined electrostatic force and cyclone centrifugal force acting together to remove solid particulates. Electrostatically generated ozone reacts with the exhaust gases to reduce them to Co and to oxidize them to harmless gases. Exhaust enters a cyclone chamber, passing through an electrode having many small pointed openings. Air is injected into the cyclone chamber to create a centrifugal flow of the air and exhaust. The electrode charges the solid particulate in the exhaust which then move toward the outer boundary of the cyclone chamber and toward a solid particulate collector. Ozone is generated near the electrode for reacting with the exhaust gases. The air and exhaust gases in the cyclone chamber are ionized in the cyclone chamber and react as the exhaust flows through the cyclone chamber and the muffler chamber to deodorize and purify the exhaust. The exhaust control apparatus includes a muffler chamber concentrically surrounding a cyclone chamber which concentrically surrounds an exhaust inlet pipe.
