摘　　要：以两种常压柴油、裂化柴油、加氢柴油和0号轻柴油为基础油,分别配制了2%、4%、6%、8%、10%的乙醇柴油。然后分别测定了乙醇柴油的互溶性和稳定性、水对乙醇柴油体系的影响和助溶剂对乙醇柴油互溶性能的影响;测定了乙醇柴油的蒸发性、低温性能、着火危险性、金属腐蚀性和橡胶溶胀性。同时,测定了乙醇柴油的发动机性能。Ethanol diesels with different ethanol concentrations were prepared by using distillate diesel, cracked diesel and hydrotreated diesel. The solubility characteristics and longtime stability of the ethanol diesels were tested. The paper also evaluated the influence of water on the stability of the ethanol diesels. Some solvents were employed to improve the anti-water capability of ethanol-diesel fuels. The evaporation characteristics, low temperature performance, fire fatalness, copper corrosion and rubber consistency of the ethanol diesels were tested. Engine tests were conducted to investigate the engine performance when using the ethanol diesel fuels.
