摘　　要：在2135柴油机上进行重柴油掺水的对比试验,测取不掺水、掺水11%、17.5%的全负荷速度特性和标定转速的负荷特性曲线,比较掺水前后柴油机的经济性、动力性以及环保性。试验结果表明:燃烧掺水乳化油是否可以节油以及节油的效果如何,与柴油机的转速和负荷有关,还与掺水的比例有关;重柴油掺水燃烧整体上可以显著降低NO和烟度排放;同时,掺水燃烧使柴油机的噪声变大。The comparison tests of water-diesel blended fuel were carried out in 2135 diesel engine with water mass proportion of 096, 11% and 17.5%. Full load speed characteristics and load characteristics at rated speed were investigated. The results show that reduction of fuel consumption is related to the engine speed, load and water proportion. The emissions of NO and PM can be reduced effectively by using water-diesel blended fuel, while engine noise increases.
