The exhaust gas from diesel engines is one of the major causes of air pollution. As one method for pollution control, the authors have been developing plasma reactors. The authors' reactor is a concentric cylinder type which has a glass tube barrier between electrodes. Connecting two of these reactors in series, the NOx (NO + NO2) component from diesel engine exhaust gas is decomposed up to 93%.



This reactor was mounted on a 3-liter diesel engine and received six-mode load testing at an authorized public facility (JARI, Tsukuba City) and cleared the legal critical value of 350 ppm of NOx. By this success, the effectiveness of discharge plasma treatment of diesel exhaust gas and its practical evaluation have been confirmed. (C) 1997 Scripta Technica, Inc.
