桑塔纳2000燃油供给系统的诊断检修 摘 要随着世界汽车整车产业的发展，汽车运用技术的不断成熟，人们对汽车的性能要求不断的提高特别在燃油方面最为突出，人们大多喜欢采用节能环保的车型针对这一发展汽车生产厂商必须在燃油供给方面功夫，桑塔纳2000的燃油供给系统就是其中一部分，在汽车节能和环保方面起到了重要作用。但在行使过程中由于各外界因的影响，从而使燃油供给系统出现一系列故障。而燃油供给系统直接影响汽车行使的稳定性和节能环保性，为此本文通过对桑塔纳2000燃油供给系统的元件介绍，分析故障和诊断排除。 Santana 2000, the fuel supply system diagnostic maintenance Abstract As the world automobile industry, automotive use of technology matures, the performance requirements for motor vehicles by increasing the fuel, especially in the most prominent, most people prefer the use of energy saving and environmental protection model for the direction of this development, automobile production manufacturers must be big in the fuel supply-side efforts, Santana 2000, the fuel supply system is part of its energy-saving and environmental protection in the car played an important role. However, in the exercise of the course of the outside world as a result of various factors in the impact of the fuel supply system so that a series of failures. Fuel supply system and a direct impact on the exercise of a motor vehicle with the stability and energy saving and environmental protection, and to this end this article on the Santana 2000, the fuel supply system components, the analysis of fault and ruled out the diagnosis. Focuses on the 2000 Santa common fuel supply system fault diagnosis and maintenance. Key words: fuel supply system; component maintenance; fault diagnosis to exclude 目录 1前言 1 2燃油供给系统主要元件构造和功用 2 2.1燃油供给系统组成 2 2.2燃油供给系统各主要元件介绍 3 2.3 汽车燃油供给系统原理 7 3 汽车燃油供给系统各主要元件检修 8 3.1燃油供给装置检修 8 3.2空气供给装置元件检修 11 3.4燃油供给系统的日常维护 12 4 综合汽车实例分析燃油供给系统的常见故障诊断 14 4.1故障诊断实例1 14 4.2 故障诊断实例2 15 总 结 17 致谢 18 参考文献 19 附录 20  1前言 随着时代的发展，社会的不断进步汽车电子技术也得到了迅速的发展，现代汽车电子技术已经成为一个国家汽车工业发展水平的标志。进入20世纪70年代后，随着汽车数量的日益增多，汽车的节能和环保与汽车污染成为了各国政府关注的话题，能源危机的影响更加突出。在汽车工业发达国家相继制定了汽车燃油经济法规，为解决节能环保与污染这一问题。在现代的汽车中采用成熟电控技术是解决燃油供给系统问题的根本。电控燃油供给系统是汽车动力输出的主要源，在汽车中燃油供给系统工作状况的好坏就直接影响着汽车的动力性，经济性和环保性。随着世界经济的全球化，各个国家在对汽车燃油供给系统工作要求不断的提高，如电控燃油喷射系统取代传统化
