真空表在诊断汽车故障中的作用

Function of Vacuum Table in Auto Fault Diaanosis

在维修技术人员越来越重视．示波器、发动机综合分析仪等相对复杂检测设备的使用时，却常常忽略真空表这样一种简单而又实用的检测工具。实际上，借助真空表对发动机的性能与故障进行分析，可以给维修诊断工作带来很多方便。在此，笔者谈谈真空表的数值分析判断，并结合典型故障案例中真空表的应用情况，与大家共同探讨真空表在诊断检测工作中的作用。

Abstract： In maintenance technicians paid more and more attention to use the oscilloscope and the engine comprehensive analyzers relatively complex testing equipment, but often the vacuum table such a simple and practical detection tool is neglected. In fact, with the aiding of engine performance vacuum table an failure analysis, many conveniences on maintenance diagnosis can be given.
