THE INFLUENCE OF GASOLINE FORMULATION ON SPECIFIC POLLUTANT EMISSIONS

Many recent research efforts have dealt with the influence of fuel composition on regulated and specific pollutant emissions from spark ignition engines. While many qualitative correlations have been already proposed, only a few quantitative ones are known (benzene is an exception). This paper describes qualitative and quantitative correlations between fuel composition and specific pollutant emissions of a spark ignition engine. The aim of this work was to find the precursors of the main specific pollutants. For each, a multilinear equation is calculated, illustrating the correlation between its concentration in exhaust gases and its content in the fuel. Results of these calculations point out which initial compound favors the formation of a determined pollutant. As lean conditions are probably going to be used in future commercial engines, the fuel effect has been studied for a broad range of equivalence ratios (0.8-1.2).
