摘要
研究了在柴油机上燃用不同掺烧比的乙醇柴油混合燃料时的排放特性,在不改变发动机基本结构的条件下,分别使用纯柴油和10%、15%及20%的乙醇柴油。进行了排放特性的对比实验。研究结果表明,加入一定比例的乙醇可以较大地降低排气烟度,NOx的排放也明显降低,而HC和CO明显上升。
The effect of emission characteristics was investigated when different kinds of ethanol-diesel blend as fuel was used directly on the diesel engine. The emission characteristics were tested on the test-bed by using diesel fuel, E10, E15 and E20 respectively. The results show that when ethanol-diesel blend is used on the diesel engine, the smoke emission decreased, and the emission of NOx also decreased, the HC and CO emissions increased simultaneously.
