Effect on Exhaust Emissions by the Use of Methylcyclopentadienyl Manganese Tricarbonyl (MMT) Fuel Additives and Other Lead Replacement Gasolines

To evaluate the effect of lead-replacement fuels on exhaust emissions, chassis dynamometer tests were conducted on four automobiles fueled with a matrix of five Pb-replacement fuels, some of which contained methylcyclopentadienyl manganese tricarbonyl (MMT).

Description
Summary:To evaluate the effect of lead-replacement fuels on exhaust emissions, chassis dynamometer tests were conducted on four automobiles fueled with a matrix of five Pb-replacement fuels, some of which contained methylcyclopentadienyl manganese tricarbonyl (MMT). Two of the vehicles were noncatalyst cars, and two were equipped with catalysts. Except for carbon monoxide of one of the cars, all pollutant emissions from the catalyst automobiles were below the emission standards for all test fuels, and the same results were found for the noncatalyst cars. The overall findings showed that the Pb-replacement fuels had no measurable effect on the emissions of CO, hydrocarbons, and nitrogen oxides, although for the noncatalyst automobiles, the fuels increased the emissions of benzene and formaldehyde.
