旋转回归设计在375柴油机减烟试验中的应用

采用多因素旋转回归设计方法 ,进行 375柴油机减烟试验 ,建立了该机的烟度及功率、油耗等综合指标随喷油嘴型号、供油时间及喷射压力而变化的关系 ,从而进行优化匹配 ,达到较好的减烟效果

Application of Rotational Regression Design in Exhaust Smoke Reduction Experiments of Type 375 Diesel

Experiments are conducted with multi-factor s rotational reqression de sign to reduce exhaust smoke of model 375 diesel. Relations between the comprehe nsive indexes, such as exhaust smoke density power output and fuel consumption, and different nozzles, injection timing and injection pressure are establish ed , on which optimization can be realized to further reduce exhaust smoke.
