I汽车发动机故障辅助分析诊断系统的设计摘 要因为电子技术近年来已经在汽车领域内得到了普遍运用, 针对维修技术人员也有了更为专业的要求。为了适应国内外汽车市场的发展进程, 设计一个能够推理汽车发动机故障的辅助分析诊断系统, 以此早日实现现代化汽车发动机故障维修。本文主要通过分析帕萨特 B5 发动机的一些常见故障后用利用 VB 软件来进行发动机故障诊断系统的一个设计，此系统可适用于汽车专业学生的教育教学，也方便了一些维修厂点的故障诊断，可提高修理的维修时效，并且节约大量仪器成本。关键词：维修时效；故障诊断；现代化；节约成本ABSTRACTBecause electronic technology has been widely used in the field of automobiles in recent years, there are also more professional requirements for maintenance technicians. In order to adapt to the development process of domestic and foreign automobile markets, an auxiliary analysis and diagnosis system capable of reasoning automobile engine faults is designed so as to realize modern automobile engine fault maintenance as soon as possible.In this paper, after analyzing some common faults of Passat B5 engine, VB software is used to design a fault diagnosis system for the engine. This system can be applied to the education and teaching of students majoring in automobile, and it is also convenient for fault diagnosis in some repair shops. It can improve the repair time and save a lot of instrument costs.Key words: Maintenance time limit,Fault diagnosis,Modernization,Cost savingsII目 录摘 要................................................................................................................................................................IABSTRACT.....................................................................................................................................................I第一章 绪论...............................................................................................................
