摘　　要：以电控柴油机台架试验数据为基础,应用曲面插值法对台架试验数据进行处理,得到柴油机万有特性图并划分燃油经济性区域,应用二元三次插值法求得柴油机有效扭矩近似值。通过分析电控柴油机实车记录的运行状态参数,统计得出柴油机不同使用工况下有效燃油消耗率的概率分布,实现对电控柴油机实车使用燃油经济性的评价。Based on the electronic controlled diesel engine bench test data, processing bench test data by nu- merical method of camber interpolation, the mapping characteristics curves are got and divided into the areas of fuel economy. By the method of bivariate cubic interpolation, the diesel engine effective torque is obtained. Through the experimental analysis of electronic controlled diesel engine running parameters recorded, diesel engine~ different work states and probability distribution of fuel consumption rate are statistically analyzed to a- chieve diesel fuel economy evaluation.
