一种对内燃机特殊性能曲线处理的数值方法

A Numerical Analysis Method of Special Performance Curves of Engines

在处理内燃机特性曲线时应选用非线性数学模型．建立了一种适合处理内燃机特性特性曲线的三次样条函数拟合的数学模型．从而为处理内燃机实验中复杂的特殊性能曲线寻找了一种新的方法．

In the processing of the performance curve of engines,nonlinear mathematical model must be adopted, especially, special performance curves of engines. Therefore, the Cubic spline suitable for processing performance curve of engine has been developed to process special performance curves of engines.
