摘要 针对汽油机CAI燃烧面临的主要难点——着火时刻控制、运行工况范围狭窄及燃烧模式转换问题,在CAI发动机运行负荷上边界采用火花助燃的方法,可灵活控制CAI发动机在负荷上限运行时的燃烧相位,抑制大负荷时CAI燃烧所遇到的爆震和小负荷时的燃烧不稳,可以拓展CAI运行的工况范围.点火时刻、缸内残余废气率和有效压缩比都对火花助燃CAI燃烧过程有重要的影响.通过对缸内残余废气快速管理,可以有效控制SI和CAI燃烧所占的比例. To solve such problems as control of ignition timing, narrow operating range and combustion mode change, which exist in the application of CAI combustion in a gasoline engine, spark-assisted CAI hybrid combustion mode were applied around high and low load boundaries. With spark assisted CAI hybrid combustion, deflagration with high load limit and instability with low load limit were avoided because of flexible control of ignition timing and combustion phase, resulting in the extension of operation range of the CAI engine. Ignition timing, residual gas fraction and effective compression ratio have great influence on spark-assisted CAI hybrid combustion process. With the rapid management of residual gas, the inflexion position in the hybrid heat release process is under control, so is the proportion of SI and CAI combustion.
