摘要
发动机外特性和万有特性是研究汽车动力性的基础,选择合适的方法进行发动机数学建模,是研究汽车动力性和燃油经济性的关键。发动机数学建模采用了曲线拟合及曲线拟合和线性插值相结合的方法,并根据某发动机的实验数据,进行了实验验证。
The external characteristic curve and universal characteristics curve are the basis of studying vehicle＇s power performance. Choosing the method suitable to carry on the engine mathematics modeling is the key of studying the car power and fuel economy. Engine mathematics modeling adopts curve fit and curve fit method combining linear interpolation, and the model is verified by the experimental data of some engine.
