摘　　要：简介了燃油消耗测量方法中的容积法、质量法以及碳平衡法的测量原理,讨论了使用上述不同测试方法时试验系统的区别,陈述了各种方法对硬件的要求,比较了碳平衡法中定容取样系统和开式排气稀释取样系统的区别,分析了应用碳平衡法与传统油耗测量方法试验结果差异的原因。Auto fuel economy is evaluated by measuring fuel consumption rate. Fuel consumption rate is measured in transient mode or steady mode. The principles of gravimetric, volumetric and carbon balance methods ~e introduced. The difference of three experiment systems is discussed. Relevant hardware requirements are illustrated. The difference of constant volume sampling system and open exhaust dilution sampling system applied in carbon balance method is showed. Reason of the difference in experimental results of carbon balance method and traditional fuel consumption quantity method is analyzed.
