摘要
汽车现在已是大众的交通工具,它集机械与电子一体,是当前社会的高科技产品。随着汽车电子技术的快速发展,电子燃油喷射、安全气囊和ABS系统以及各种电控部件的应用技术都日趋成熟,电子智能系统几乎已经应用到汽车的各个领域。
这些高科技的应用使得汽车更趋近完善,但同时也使得在维修汽车上增加了许多难度。本论文针对汽车发动机冷却系统存在的各种典型故障,进行了仔细的故障分析和维修过程,解决发动机冷却系统存在的具体问题。目的就是为了对发动机冷却系统进行深刻透彻的分析,使得在实际维修中得到更好的经验和方法。从而使发动机冷却系统更出色的工作,提高汽车的动力性和经济性,提高汽车的使用寿命。
关键词:发动机发动机冷却系统智能化检测维修
Abstract
Cars are now already is public transportation, it integrates mechanical and electrical integration, the present society of high-tech products. Along with the rapid development of automobile electronic technology, electronic fuel injection, airbag and ABS system and various ponents application technology matures, electronic intelligence system has been applied to the car's almost every field.
These high-tech application makes cars more intimate perfect, but also makes the maintenance bus increased a lot of difficulty. This thesis aims to automobile engine cooling system various existing typical fault, the careful fault analysis and maintenance process and resolve the engine cooling system exist specific problems. Purpose to the engine cooling system on deep thorough analysis, make in the actual repairs better experiences and methods. Thus make the engine cooling system more outstanding work, improve the performance and fuel economy car, improve the service life
