摘要:
为了减少实验次数，寻找最佳参数匹配，使用正交实验设计方法，选取异戊醇掺混比、喷油提前角、进气温度、扫气压力4个参数的各4个水平进行仿真实验，以NO质量分数和指示功率作为实验的评价指标进行正交设计，运用数据极差分析寻求最佳参数组合。结果表明，得到的最优参数为：异戊醇掺混比为体积分数40%，喷油提前角为22.6°，进气温度为315.15 K，扫气压力为0.233 MPa。在此参数组合下得到最终生成的NO质量分数为0.011 02%，指示功率为52.10 kW。可见，在动力性损耗较小的情况下可以实现较高的异戊醇掺混比。
Abstract:
In order to reduce the number of experiments and find the best parameter matching,this study employed an orthogonal experimental design method,four levels for each of the four parameters,including isoamyl alcohol mixing ratio,injection advance angle,intake temperature,and scavenging air pressure,were selected for simulation tests. The NO mass fraction and indicated power were used as the evaluation indexes of the test,and the orthogonal design was carried out to seek the optimal parameter combinations by using data extreme variance analysis. The results showed that the isoamyl alcohol mixing ratio was 40%,fuel injection advance angle was 22.6°,intake temperature was 315.15 K,and scavenging air pressure was 0.233 MPa. With this parameter combination,the following results were obtained: NO mass fraction was 0.011 02%,and indicated power was 52.10 kW. So higher isoamyl alcohol mixing ratio could be achieved with less power loss.
