摘　　要：通过FTA方法,根据一些汽车油耗的数据对汽车油控进行分析计算,得出对汽车油耗的影响最大因子或因子组合,从而对其进行设计、改进、故障诊断及故障维修等.对影响国内某汽车中的轻型汽车油耗参数的燃料消耗量和比功率两个因子进行定性和定量分析,得出汽车的比功率对汽车的油耗参数影响程度较大的结论.By the FTA （Fault Tree Analysis）method, we can analyze and calculate vehicles oil control according to vehicles oil-consumption data, then figure out a factor or a combination of factors that af- fect vehicles oil-consumption most, so that we can design, improve, diagnose the fault or corrective maintenance about vehicles oil control. This paper analyzes the two factors qualitatively and quantita- tively that affecting the fuel consumption and specific power of certain domestic automobile brand, then draws the conclusion that the degree of impact on the specific power of the automobile affected the vehicles oil-consumption parameters a lot.
