重型卡车发动机维修中故障诊断技术的要点分析

Analysis of the Key Points of Fault Diagnosis Technology in Heavy-duty Truck Engine Repair

道路上常见大型重型卡车,该类卡车承载量强大,在各项目过程中也承担起主要的运输任务。要想让其正常行驶,减少事故发生,就必须重视发动机。发动机是重型卡车的“心脏”,为重型卡车提供动力支持,如出现故障就必须做好检查与维修工作。因此,维修人员需了解重型卡车发动机设计特点以及故障特点,并从声音、烟色等多方面判断故障,再开展故障维修工作。由于重型卡车使用时间长,在时间的作用下,发动机频繁工作易出现多种故障。基于此,本文就重型卡车发动机维修中故障诊断技术要点展开详细探讨。

Large heavy-duty trucks are common on the road, which have a strong carrying capacity and also undertake the main transportation tasks in the process of various projects. In order to make it run normally and reduce accidents, it is necessary to pay attention to the engine. The engine is the “heart” of heavy-duty trucks, providing power support for heavy-duty trucks, and must be inspected and repaired if there is a failure. Therefore, maintenance personnel need to understand the design characteristics and fault characteristics of heavy truck engines, and judge the fault from many aspects such as sound and smoke color, and then carry out fault maintenance work. Due to the long use time of heavy trucks, under the action of time, the engine is prone to a variety of failures when working frequently. Based on this, this article discusses in detail the technical points of fault diagnosis in the maintenance of heavy-duty truck engines.
