Experimental Research on MMT of the Influence on Particulate Emission of GDI Engine

The effects of methyl cyclopentadienyl manganese tricarbonyl (MMT) on emissions for the gasoline engine were studied using the DMS500 instrument on a chassis dynamometer. The fuels used in this study were one base gasoline and three types of blend oil (base gasoline with MMT). Different revolutions per minute and load were tested. Results showed that: under the full load, the same fuel emissions number concentration increases with the increasing trend with the revolutions per minute; the number concentration of emissions used same fuel reached the minimum in medium load, when revolution is constant, which will increased dramatically in heavy load; with increasing concentration of manganese in gasoline, the number of PM2.5 in vehicle exhaust emission was increased.
