车型:配置1.6L LDE发动机、6T30E自动变速器。行驶里程:56000km。故障现象:此车为救援回来车辆,据客户反映车辆在正常行驶中熄火,再也无法启动。救援人员在现场发现启动车辆时存在明显缸压不足的情况,因现场条件所限无法排除故障将车拖回厂维修。在这里介绍一下通用汽车新开发的工具WPS500X压力传感器,它能通过示波器让我们看到汽缸的压力变化,我们可以将故障车汽缸压力变化波形与正常车辆的汽缸压力变化波形比较,找出差异从而推理出故障部位。实物图如图1所示。高强度压缩
Model: Configuration 1.6L LDE engine, 6T30E automatic transmission. Mileage: 56000km. Symptom: This car back to rescue vehicles, according to the customer reflects the vehicle in the normal driving flame, can no longer start. Rescue workers at the scene found that there is a clear lack of cylinder pressure when starting the case, due to site conditions can not rule out the problem drag the car back to the factory maintenance. Here to introduce the new tools developed by General Motors WPS500X pressure sensor, which allows us to see through the oscilloscope cylinder pressure changes, we can fault car cylinder pressure waveform changes and normal vehicle cylinder pressure waveform to find differences Reasoning out the fault location. Figure shown in Figure 1. High-intensity compression
