摘　　要：汽车燃油消耗量的测量具有重要意义,但现有的测量方法难以实现不解体快速测量。依据碳平衡法原理,建立测量汽车燃油消耗量的碳平衡法模型,并设计测试系统。为减小由于碳平衡法基本假设所带来的偏差,对碳平衡法模型进行修正。由此,可通过测量尾气中CO、CO2、HC的含量,得到汽车燃油消耗量。试验结果表明,该方法有较好的精度及稳定性,可用于汽车燃油消耗量的检测。Measuring the fuel consumption of the vehicles is very important,but the existing methods are inconvenient to be used in the undisassemble measurement.This paper presents a carbon balance method model based on gasoline carbon content,the test system design,and a modifying method to minimize the error caused by the carbon balance method.By measuring the total flow and the composition (CO,CO\-2,HC) of the vehicle emission,the fuel consumption could be calculated.The experiment test results indicated that this test system and model are good in accuracy and stability for different vehicles,and could be used to measure the fuel consumption of the vehicles.
