论文简介： In order to gain better understanding of the effect of fuel components on engine out hydrocarbon emissions, a single cylinder engine has been run on hexane gasoline and xylene gasoline blends, total HC emissions have been measured by FID. The influence of the fractions of paraffinic component (hexane) and aromatic component (xylene) blended in gasoline on engine out HC emi ssions were examined. The comparisons of these blends with commercial gasoline were provided. The results show that total HC emissions for hexane gasoline blends are lower than that of gasoline and total HC emissions for xylene gasoline blends are higher than that of gasoline. It is shown that Henrys constant, diffusion coefficient and distillation temperature of fuel components dominate the mass of in cylinder unburned hydrocarbons which is influenced by fuel. The compositions of fuel greatly influence the engine out HC emissions. The engine out HC emissions vary linearly with the fraction of hexane or xylene blended in gasoline, total HC emissions decrease 2.0×10 -4 C as the fraction of hexane blended in gasoline increases 10 per cent, total HC emissions increase 2.2×10 -4 C as the fraction of xylene blended in gasoline increases 10 per cent.
