生物质燃油/柴油混合燃料燃烧特性

Combustion Characteristics of a Diesel Engine Operated with the Burning Oil of Biomass and Diesel Blend Fuel

在测定生物质燃油物理特性的基础上,将生物质燃油和柴油配比,筛选出不同体积分数的混合燃料E110(10%1号生物质燃油和90%柴油混合)、E210(10%2号生物质燃油和90%柴油混合)、E120(20%1号生物质燃油和80%柴油混合)、E220(20%2号生物质燃油和80%柴油混合)。用这些混合燃料与柴油进行了台架对比试验。结果表明,在不改变发动机结构的情况下,燃用混合燃料是可行的,发动机性能没有明显的变化,节油效果显著。

On the basis of testing thermo-physical characteristic of the burning oil of biomass, the mixed fuel by volume E1 - 10（10% No. 1 burning oil of biomass and 90M diesel）,E2 - 10 （10% No. 2 burning oil of biomass and 90M diesel）,E1 - 20 （20% No. 1 burning oil of biomass and 80% diesel）,E2 - 20 （20% No. 2 burning oil of biomass and 80% diesel）, was screened from a variety of the burning oil of biomass and diesel fuel, and a comparative control experime＇nt was conducted between the mixed fuel and pure diesel. The present work investigates the effect of substituting an alternative fuel for conventional diesel fuel for combustion of mixed fuels in an unmodified diesel engine. The test results showed that there was no deference in performance between a diesel fuel and mixed fuel. The specific fuel consumption results with mixed fuels were lower than that when diesel fuel was used at various loading.
