浅谈汽车润滑系统故障诊断与维修

Discussion on Fault Diagnosis and Maintenance of Automotive Lubricating System

该文就驾驶员送修车辆的故障现象及车辆的实际工况,通过常规故障诊断思路进行了判断分析排除,初步掌握了该车的故障原因;接着按照检修流程由简到难的次序进行检查,一方面是来印证之前的分析判断是否正确;另一方面也是找出真实故障点。之后通过对润滑系统的故障分析,我们发现最可能出现的故障是:润滑油变质、润滑油压力过高、润滑油压力过低、润滑油消耗过多、润滑油平面升高等,并对故障现象、原因、排除进行了阐述。

Provided that the driver’s vehicle fault phenomenon and the vehicle’s actual condition,the conventional fault diagnosis was applied to initially analyze and judge the potential causes of the car defect.In order to validate the previous analysis and judgment as well as find out the real fault cause,the vehicle was inspected based on a simple to difficult repair process.After analyzing the failure of the lubrication system,we found the most likely failure is:modification of lubricating oil,lubricating oil pressure,oil pressure is too low,excessive consumption of lubricating oil,lubricating oil level rising.And the fault phenomenon,reason,exclusion are described.
