Abstract
Particulate pollutants such as carbonaceous particles are removed from an engine exhaust stream by passing the exhaust stream through an exhaust gas reactor, the exhaust stream first traversing a charging zone wherein the particles are charged via a corona discharge, and thereafter traversing a downstream collection zone wherein the charged particles are collected and eliminated by a collector/reactor having an oppositely charged reactive collecting surface.
