柴油发动机地沟油燃烧与排放特性仿真试验

摘要

为解决石油资源短缺和环境污染的问题，将地沟油作为新能源应用于柴油发动机中，运用GT—Power发动机仿真软件分析地沟油的燃烧特性与排放特性。仿真结果表明：发动机燃用地沟油时较燃用纯柴油时功率有所下降，燃油消耗率升高，有害排放物中CO明显降低而NOx并无明显变化。燃用地沟油和甲醇的混合燃料时其动力性、经济性和排放特性要比单独燃用地沟油或甲醇时均有所改善。%To solve the problem of shortage of petroleum resources and environmental poIlution, waste oil as a new energy was used in diesel engines. The GT -Power engine simulation software is used to analyze the combustion characteristics and emission characteristics of the waste oil. Simulation results show that diesel engine fueled with waste oil power have shown that power drops, fuel consumption increases, harmful emissions of CO, NOx have no significant changes ; However, fueled with methanol and waste oil mixture, engine power, economy and emission characteristics were apparently improved than separate burning waste oil or methanol.
