摘　　要：在一台ZX195型单缸柴油机上,通过在柴油中添加甲醇含氧燃料及适量的添加剂,研究了在高原地区常用工况下含氧混合燃料对柴油机性能及排放的影响。试验结果表明,含氧混合燃料可以有效改善柴油机的烟度排放,在大负荷下尤为明显。而对动力性影响很少,经济性得到改善。An experiment was carried out on a ZX195 diesel engine of single cylinder.The fuel used in the experiment is obtained by mixing diesel fuel with methanol and some additive.Comparison and analysis are made to the dynamical efficiency,economical efficiency and the emission of the engine using Oxygenated fuel in the area of altiplano.The result shows that the dynamical efficiency changes little,but the burning efficiency is greatly improved and the economical efficiency is enhanced.The emission of smoke is remarkably reduced, specially at load condition increased.
