The Effect of Manganese Fuel Additive and Exhaust Gas Recirculation on Diesel Particulate Emissions 860621

A study was undertaken to determine the combined effect of methylcyclopentadienyl manganese tricarbonyl (MMT) fuel additive and exhaust gas recirculation (EGR) on particulate and oxides of nitrogen (NOx) emissions from a single-cylinder light-duty diesel engine. Further, the physical and chemical properties of the particulate material were determined to better understand MMT and EGR effects on these emissions. The results showed that EGR always decreased NOx emissions, and that MMT had no significant effect on them. In addition, EGR always increased particulate emissions, but MMT was effective in limiting this increase especially at high EGR levels.
