| 摘 要： | 利用三元相图研究了柴油-米糠油生物柴油-乙醇混合燃料在不同温度和不同乙醇质量分数下的稳定性。选取不同配比的混合燃料对其燃料特性以及在发动机上燃用时燃烧和排放状况进行了研究,并与普通柴油进行了比较。研究表明随着温度降低,三相系统的稳定性降低;乙醇的含水率对系统稳定性有很大影响,含水率越大系统稳定性越差;混合燃料的燃料特性和普通柴油有一定差别,但总体上并不十分明显;随着混合燃料中乙醇含量增加,发动机输出功率降低,有效燃油消耗率增加,但与普通柴油相差并不大;CO、HC、NOx的排放量也随着乙醇含量增加而增加。掺入米糠油生物柴油可以明显改善柴油醇的燃料特性以及燃烧和排放状况。

| Abstract: | Via the phase diagram of diesel-rice bran oil biodiesel-ethanol blends at different purities of ethanol and different temperatures, the stability of the mix fuel system was studied. Fuel properties (such as density, heat of combustion, cetane number, flash point) of the selected blends and their emissions performance in a diesel engine were examined and compared to those of base diesel. With decrease of temperature, the solubility of diesel-rice bran oil biodiesel-ethanol blends system was decreased. The moisture content of ethanol had a great influence on mixture solubility. With increase of moisture content, the solubility of system was decreased. The fuel properties of blend were similar to those of base diesel. With the ethanol content of blends increasing,the power was decreased and BSFC was increased. The CO, HC and NOx emissions were increased when the ethanol content of blends was increased. The results show that the fuel properties, combustion properties and emissions of diesohol can be improved by adding rice bran oil biodiesel. |
