摘　　要：通过对汽车发动机外特性的理论分析,在处理汽车发动机外特性曲线时,建立了一种适合处理发动机外特性曲线的三次样条函数拟合的数学模型,在C++Builder可视化开发平台上,编制了汽车发动机外特性曲线绘制程序。利用三次样条函数插值法对实验数据进行拟合,实现了发动机外特性曲线绘制的自动化。The author synthetically analysizes it's full load speed characteristics, In the processing of the full load speed characteristics curve of engine, mathematical model must be adopted. Therefore the cubic spline suitable for processing full load speed characteristics curve of engine has been developed to process special performance curves of engine.The program structure diagram and source programs of full load speed characteristics curve of engine are put forward by the Borland C++ Builder .
