气温对汽车运行油耗的影响复杂而难以控制。为了寻找它们之间的关系,本文从大量的汽车实际运行油耗资料中分离气温影响因素、对我国由北到南按年平均气温递减选择七个城市的有关油耗统计资料、对其油耗增长率与气温进行回归分析,得出二者的线性关系,推导了汽车运行油耗与气温成二次曲线关系式。该关系式是制定油耗定额和确定气温修正系数的主要依据。
The impact of temperature on vehicle fuel consumption is complex and difficult to control. In order to find out the relationship between them, this paper analyzes the influencing factors of air temperature from a large number of actual fuel consumption data of automobiles, and selects the statistical data of fuel consumption of seven cities from north to south according to decreasing annual average temperature, Regression analysis of temperature, draw the linear relationship between the two, derived the car running fuel consumption and temperature into a quadratic curve relationship. The relationship is to develop fuel consumption quotas and determine the main basis for temperature correction factor.
