This article describes a study on a non-thermal plasma device to treat exhaust gases in an internal combustion engine. Several tests using a plasma device to treat exhaust gases are conducted on a Honda GX200-196 cm3 engine at different rotational speeds. A plasma reactor could be efficient in degrading nitrogen oxides and particulate matter. Monoxide and carbon dioxide treatment is minimal. However, achieving 1%–3% degradation may be interesting to reduce the emission of greenhouse gases.
6 size channels: 0.3, 0.5, 1.0, 2.0, 5.0, and 10.0 μmFlow rate 2.83 L/min controlled by internal pumpCounting efficiency 50% at 0.3 μm; 100% for particles>0.45 μmRelative humidity±7%, 20% to 90% non-condensing
