摘要
利用插值拟合的方法绘制了某发动机的转矩特性曲面。根据发动机稳定工作的边界条件,在功率曲面上确定了发动机稳定工作的边界曲线。利用定时油耗公式计算出发动机功率特性曲面上的经济工作曲线。以该曲线作为发动机稳定工作线,研究了胶带式无级变速器在不同载荷、坡度角的经济性调速特性。
The curved surface of characteristics of motor engine was established in this paper on the basis of test data of engine. Then, the boundary-line that decided the area of engine working steadily was founded on the curved surface of characteristics. At last, the properties of ratio changing of rub- ber-belt CVT were analyzed with different loads and road slop according to the fuel economy-line of engine working steadily, which was obtained by the use of a formula of fuel consumption.
