汽车发动机温度异常的故障诊断与排除

发动机作为汽车的心脏,而维持发动机能够正常工作运转的重要系统之一就是发动机的冷却系统。对于发动机而言,最常见的故障莫过于发动机冷却液温度的异常,发动机冷却液温度异常会造成发动机过热,从而除了降低发动机功率外,还会增加发动机的燃油消耗。本文通过分析导致发动机冷却液温度过高的原因,同时找出了故障诊断以及排除的一般方法和思路。

Fault Diagnosis and Troubleshooting for Abnormal Temperature of Vehicle Engines

The engine is the heart of the car. And the engine cooling system is one of the important systems to maintain engine operates well. The most common fault is the abnormal engine coolant temperature, engine coolant temperature anomalies may cause the engine to overheat, which not only reduces engine power, but increases the engine fuel consumption. This paper analyzes the cause of the abnormal engine coolant temperature, finds the fault diagnosis and comes up with the general methods and ideas.
