采用一种改进型的串联式离子电流检测系统，在一台1.3L四缸增压汽油机上开展了离子电流信号的典型特性，尤其是爆燃工况下特性的试验研究.结果表明：该检测系统离子电流的频率特性可较好地判定中强爆燃工况，但在轻微爆燃工况有一定的局限；离子电流积分值能进一步提高爆燃工况判定的准确率，达到87.2％.针对爆燃强度的识别，离子电流峰值和平均幅值与爆燃强度有很强的正相关性，采用加权平均的数学方法能优化离子电流爆燃
对一台增压中冷高压共轨的柴油发动机,燃用煤基费托合成柴油(F-T柴油)时的燃烧、排放特性和微粒粒度分布特征进行试验研究,分析了F-T柴油对发动机燃烧和排放的影响规律.结果表明,与国V柴油相比,燃用F-T柴油时因密度低,在喷油策略不做改变的情况下,转矩有所降低.同时,由于F-T柴油主要成分为直链烷烃,燃料着火性好,十六烷值较高,滞燃期明显缩短,预混合燃烧阶段放热量减少,燃烧时缸内温度降低,有利于降低
