以 4 12 5A4柴油机为研究对象 ,利用SAS(统计分析系统 )软件包 ,运用多项式回归的方法 ,寻求柴油机功率与最高空转转速及额定转速下耗油量之间的内在定量关系 ,以期为柴油机的无载测功提供一种新方法。建立的模型其误差可以控制在 3%以内。
Taking the 4 12 5A4 diesel engine as the research object and utilizing the SAS (statistical analysis system) software package and using the polynomial regression method to seek the inherent quantitative relationship between the diesel engine power, the maximum idle speed and the fuel consumption at the rated speed, No load test provides a new method. The error of the established model can be controlled within 3%.
