摘　　要：燃料经济性作为汽车的重要性能指标之一,一直是汽车技术研究人员研究的重点。汽车的等速油耗性能是汽车的一项重要油耗性能,是分析汽车燃料经济性的重要参数。为了得到汽车的等速油耗性能,我们按照所需测量的速度编制相对应速度-时间驾驶曲线,用底盘测功机模拟车辆道路受力情况,基于全流稀释采样法采集排放尾气,用碳平衡法通过测量稀释尾气中的HC、CO和CO2气体浓度,测量出不同速度下的等速油耗性能。As one of the important performance indicators of automobiles,fuel economy has always been the focus of research by automobile technology researchers.The constant velocity fuel consumption performance of a car is an important fuel consumption performance of a car and an important parameter for analyzing the fuel economy of a car.In order to obtain the constant speed fuel consumption performance of the car,we compile the corresponding speed-time driving curve according to the required measured speed,use the chassis dynamometer to simulate the vehicle road stress,collect the exhaust gas based on the full-flow dilution sampling method,and measure the concentration of HC,CO and CO2 in the diluted exhaust gas,using carbon balance,so as to measure the constant velocity fuel consumption performance at different speeds.
