摘要： PROBLEM TO BE SOLVED: To provide a mechanism for converting particulate matter(PM) in exhaust gas from a gasoline engine. SOLUTION: This mechanism for converting PM in exhaust gas includes an engine operated at a stoichiometric air fuel ratio, a plasma generator for converting steam in exhaust gas into oxidant and an exhaust mechanism containing a filter located downstreams of the plasma generator. Plasma-treated steam is used as an oxidant for converting PM trapped on the filter arranged in the exhaust mechanism and/or oxidizing NO and/or N2 into NO2 (these steam, PM, NO and N2 exist in the exhaust gas from a gasoline engine operated at a stoichimetric air-fuel ratio), and then NO2 is used for burning PM. Experimentally, plasma is used for converting gaseous hydrocarbon under the existance and non-existance of water, followed by measurement using mass spectrometry.
