摘要： 对按特定比例混合制得的具有不同着火性的丁醇/柴油混合燃料的燃烧及排放特性进行了试验研究,分析了丁醇掺混比例、废气再循环量等参数对发动机燃烧和排放的影响规律。试验结果表明:随着丁醇比例的增大,发动机滞燃期延长,预混合燃烧量增大,燃烧定容性有所改善;混合燃料配合使用废气再循环能够实现NOx和烟度的同时降低,但在一定程度上会导致发动机的动力性和燃油经济性变差。通过合理调整燃烧相位与废气再循环(EGR)率的匹配关系,能够在较低的总体排放水平下,恢复因燃用醇类燃料造成的动力性损失,提高发动机效率及燃油经济性。

Abstract: The effect of butanol/diesel blend fuel on combustion and emission characteristics of a compression ignition engine is investigated. The action mechanisms of several boundary parameters, such as butanol fraction, Exhaust Gas Recirculation (EGR) rate and combustion phasing, are analyzed. The results show that with the increase in butanol fraction, the ignition delay is extended and a higher proportion of premixed combustion is obtained, thus, better combustion timeliness can be achieved. The smoke and NOx emissions are reduced simultaneously with a combined application of EGR and blended fuel. However, this compromises the engine output and the indicated thermal efficiency. In order to recover the lost power output due to the joint use of ESR and blended fuel, the combustion phasing is adjusted to match the specific ESR rates used in the tests. With an appropriate strategy, the power output of the engine can be recovered with almost no influence on the overall emission.

Key words: power machinery engineering, butanol/diesel blended fuel, combustion optimization, exhaust gas recirculation(EGR), emission control
