ABSTRACT:
An exhaust gas purifying apparatus for an internal combustion engine, wherein the efficiency of exhaust gas purification is enhanced by optimally controlling the operating condition of a plasma generator mounted in an exhaust passage in accordance with the exhaust gas atmosphere. The exhaust gas purifying apparatus includes a detection unit for detecting exhaust water content and exhaust temperature; and a control unit for controlling at least one of two factors, frequency or voltage of an AC voltage used to operate the plasma generator mounted in the exhaust passage, in accordance with the detected exhaust water content and exhaust temperature.
