| 摘 要： | 应用自行开发的柴油机瞬态工况测控系统,试验研究了燃料着火性对小型直喷式柴油机稳态及恒转速增转矩瞬态工况下排放特性的影响规律。研究结果表明:在稳态工况下,随着燃料十六烷值的增大,滞燃期缩短,HC、NOx排放降低,消光烟度增加;在恒转速增转矩瞬态工况,随着十六烷值的增大,烟度排放恶化,NOx排放降低。综合考虑消光烟度和NOx排放,存在一个最佳十六烷值。对于排气烟度,燃料十六烷值存在2个界限,当十六烷值小于50或大于60时,对消光烟度影响明显加剧。

| Abstract: | With a self-made transient operation condition control and measure system,the effects of the fuel cetane number on emissions behavior from a small direct injection diesel engine have been studied under steady and transient operation conditions.The experiment results showed that the smoke increases and HC and NOx emission decreases while ignition delay shortens with the increase of the cetane number under steady operation conditions.The smoke increases and NOx emission decreases with the cetane number increa... |
