本工作利用其替代品乙二醇测试了氢化生物质热解油与柴油的混溶性及其在柴油发动机中的适用性。测试了乙二醇和1,3-丙二醇与柴油的混溶性，发现只有10%体积的乙二醇可以与柴油混合，而1,3-丙二醇与柴油不混溶。为了进行直接比较，在柴油机上在相同的操作条件下对10%乙醇-90%柴油、10%乙烯-90%柴油和10%乙酸乙酯-90%柴油混合物进行了测试。乙二醇的发动机性能与乙醇和乙酸乙酯相当。混合燃料的制动比燃料消耗和废气温度没有显着差异。这三种含氧化合物的二氧化碳排放量均低于柴油。此外，乙二醇和乙酸乙酯还可以减少NOx的排放。所有三种燃料都报告了烟尘排放量的减少。这项工作提供了乙二醇（氢化生物油）用作柴油中有用的添加剂（体积高达 10%）的可能性。
In this work, the miscibility of hydrogenated biomass-pyrolysis-oil with diesel and its applicability in diesel engine has been tested by using its surrogate-ethylene glycol. The miscibility of ethylene glycol and 1,3-propylene glycol with diesel has been tested, finding that only 10% vol ethylene glycol could be mixed with diesel and 1,3-propylene glycol is immiscible with diesel. In order to make a direct comparison, 10% ethanol-90% diesel, 10% ethylene-90% diesel, and 10% ethyl acetate-90% diesel blends have been tested in a diesel engine under the same operation conditions. The engine performance of ethylene glycol is comparable to ethanol and ethyl acetate. There is no significant difference in brake specific fuel consumption and exhaust gas temperature for blends. The three oxygenated compounds all have lower CO emissions than diesel. Besides, ethylene glycol and ethyl acetate could reduce the NOx emission. All the three fuels have reported the reduction of soot emission. This work offers the possibility that ethylene glycol (hydrogenated bio-oil) could be used as a useful additive (up to 10% vol) in diesel.
