摘　　要：乘用车燃油经济性是评价车辆性能的重要指标,通常以在一定循环行驶试验工况下,行驶100km所消耗燃油升数(单位为L/100km)作为评价指标。影响乘用车燃油经济性的因素很多,文章以公司某在研SUV为例,通过仿真及转鼓油耗测试手段,在保证车辆驾驶体验体验前提下,研究如何降低整车燃油经济性。Fuel economy of passenger car is an important index to evaluate vehicle performance.In general,the fuel consumption of 100km(L/100km)under a certain cycle driving test condition is taken as the evaluation index.There are many factors that affect the fuel economy of passenger cars.In this paper,taking a SUV under research as an example,through simulation and drum fuel consumption test methods,under the premise of ensuring vehicle driving experience,research on reducing vehicle fuel economy.
