ELECTRIC TREATING METHOD FOR EXHAUST GAS OF DIESEL ENGINE AND ITS DEVICE

摘要

There is provided a diesel engine exhaust gas processing technology that can highly efficiently collect PMs in an exhaust gas from a diesel engine and demonstrate stable performance for a long period of time. A discharge and charge region formed of a corona discharge region and a charge region is provided on an upstream side of an exhaust gas path, particulate matters mainly containing carbon in an exhaust gas are changed with corona-discharged electrons, and a collection region arranged in the exhaust gas path collects the charged particulate matters.
