摘要
在一台4102QB型直喷式柴油机上研究了柴油与不同添加比例甲醇相混合的燃料对柴油机动力性能和排放性能的影响。试验结果表明,在柴油机参数不作任何改动的情况下,燃料中随着甲醇添加比例的增加,柴油机的动力性有所下降,柴油机烟度和CO的排放量都明显降低,但HC和NOx的排放量有所增加。
Engine experiments were conducted on a 4102QB DI diesel engine to study the effects of the mixed fuels on engine performance and emission characteristics. The fuels are pure 0^# commercial diesel fuel and its blends containing different proportions of methanol. Compared with pure diesel, blended fuels lower the engine power output a little. The emissions of smoke and CO are reduced with the increase of methanol percentage, while the emissions of NOx and HC increase under the same engine operating parameters and conditions.
