摘  要:
利用高效液相色谱仪对柴油机燃用普通柴油(D)和乙醇-生物柴油-柴油(EBD)排放物中的醛酮类化合物进行比较分析。研究结果表明:标定转速,10%和50%负荷下,EBD总排放量比D分别降低了2.98%和16.42%,全负荷下,升高了11.79%;排放物以甲醛、乙醛、丙烯醛和丙酮等C1~C3污染物为主,占醛酮排放物91.9%以上;负荷增加或转速降低,醛酮类排放物减少。

摘  要:
The different carbonyl compounds emission from ethanol-biodiesel-diesel and diesel were investigated using high-performance liquid chromatography.The result showed that at rated speed,the overall specific emission of carbonyl compounds decreased by 2.98% at 10% load and 16.42% at 50% load,meanwhile,increased by 11.79% at full load.The C1~C3 pollutants of formaldehyde,acetaldehyde,acrolein-acetone are the main carbonyl compounds,and up to 91.9% among carbonyl compounds emission.In general,the emission of carbonay compounds decreased as load increasing or speed decreasing.
