The Experimental Research Of Ethanol-Diesel Oil Emulsified Fuel

Presently, the world is facing an energy crisis, the petroleum is taking the non-renewable resources, its storage capacity is reducing day by day. Our country also already changed from the petroleum export country to the petroleum import country, moreover the import volume assumed every year is a large scale increaseing tendency. How to solve the increasingly stern energy problem, already became an urgent question suspending in front of a people. On the other hand, people's environmental protection consciousness is more and more strong, and has constituted more strict laws and regulations, our country has also discharged the improved standard in 2005. Facing day by day exhausting energy and the stricter laws and regulations, it is especially important and essential to develop new non-pollution and clean alternate fuel for the development of automobile in the future. The sort of new non-pollution and clean automobile alternate fuel is very many, this article has studied the influence of ethanol- diesel oil emulsification fuel to the dynamic characteristic, fuel economy and emission characteristic of a diesel engine emphatically.The article first embarks from the necessity of developing alternate fuel, through elaborating the automobile alternate fuel development condition and the incoming vehicle engine development tendency, has pointed out this topic research in significance, research content as well as research question and so on key difficulty.The article main body partial elaborates the ethanol - diesel oil emulsification fuel emulsification rationale with emphasis, the emulsification of the ethanol and the diesel oil, as well as the dyno experiment of a diesel engine using ethanol - diesel oil emulsification fuel. Were partial in the emulsified theory, elaborates the emulsion shape and the characteristic, the commonly used emulsifier choosing, the emulsion unstable way as well as the factor influences the emulsion stability. In the ethanol -diesel oil emulsification fuel configuration part, introduces the ethanol and the diesel oil physics and chemistry nature as well as this topic laboratory with the emulsifier and the emulsified plan, and has pointed out the configuration emulsified fuel in physics and chemistry nature change through the experiment and the data. In theengine dyno test portion, obtains the data and the diagram of curves through the experiment, has analyzed the influence of the ethanol - diesel oil emulsification fuel to engine dynamic characteristic, fuel economy as well as emission characteristic.The article finally summarized the questions of applying the ethanol - diesel oil emulsification fuel to the vehicles as well as the preliminary solutions. Finally, the article has carried on the summary to this experimental research, has pointed out the prospect of using ethanol diesel blends.
