Abstract: A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO₂, CO and hydrocarbon levels, accompanied by an increase in NO levels, were found.

Keywords: automotive pollution; microwave induced plasmas; non-thermal plasmas.
