车辆检修过程中,针对某一故障现象,如何将读取的发动机数据与实际故障原因联系到一起,是我们很多技术人员比较头痛的一件事情。在我们遇到发动机怠速不稳、加速不良、动力不足等故障时,经常面临不能找出数据流中的异常数据,无法确定故障原因的问题。这其中,最为困难的是判断空气流量传感器的数据是否正常、喷油量的数据是否正常等问题。如何理解各数据之间的关系,如何能够通过数据来做出正确的故障判断是我们下面将要探讨的主要内容。
Vehicle maintenance process, for a fault phenomenon, how to read the engine data and the actual cause of the fault linked to many of our technical staff is a headache thing. When we encounter engine idle speed instability, poor acceleration, lack of power and other failures, often can not find out the abnormal data flow, unable to determine the cause of the problem. Among them, the most difficult is to determine the air flow sensor data is normal, the amount of fuel injection data is normal and other issues. How to understand the relationship between the various data, how to make the correct fault judgment through the data is the main content we will explore below.
