【摘要】 提出了发动机性能试验多工况多指标的综合寻优，即针对１３工况试验时，如何组合不同工况下的喷油提前角，使发动机的综合性能指标最优．采用了一系列数学变换的方法，将这个多目标多变量寻优问题转变为一系列单变量无约束问题求解．验证试验的结果表明，寻优结果与试验结果比较一致，说明该方法对指导发动机参数的调整有重要意义．更多还原

【Abstract】 A method of optimization for multi-target and multi-mood engine experiment is Put up in this paper. That is, how to set the injection timing of diesel in order to obtain the best result totally .in the 13-mood test. The optimization results are in good agreement with the test results, and it is a useful method for running parameter adjustment of engine.更多还原
