In order to clear away the error causing by discrete type modified coefficients, this paperuses curved approximation method to formulize the operating condition modified coefficientsin the computation formula of automotive operation fuel exhaustion. The obtained relationalexpressions between monthly average ambient temperature, height above sea level and themodified coefficients are satisfactory. In addition, the author suggests that the fi be used as acomprehensive variable of road modified coefficient and the quantitative relation be...
