设计（论文）题目： 丰田卡罗拉发动机电控系统 故障诊断方法 摘 要在现今社会中，汽车已经发展为一种技术成熟，机电液合一的物品。在这其中，发电机的电子控制不断升级，已经成为推动汽车行业向前发展的巨大推动力。[7]这是因为发动机电子控制程序，是现代汽车正常运作的核心程序，是掌握正常驱动的主要因素，我们常常从发动机角度评判一辆车的性能高低，安全度高低，废气排量情况以及消耗油量情况，还以此来判断汽车是否能使乘客和驾驶员乘坐或驾驶时更加舒服自在 [1]。本文以丰田卡罗拉发动机电控系统为例，通过查阅相关文献与资料，了解丰田卡罗拉发动机的基本组成与原理，然后将部分常见的故障检查途径与专用设备判断综合起来考虑，共同用于探究卡罗拉发动机电控系统故障频发的现象，比如发动机抖动，怠速抖动，排气时尾气冒黑烟等进行诊断分析，总结出一个对于丰田卡罗拉发动机电控系统来说最为简易，方便的诊断方法。本文主要是分析卡罗拉发动机电控系统发动机抖动，怠速抖动和排气冒黑烟等故障现象，深入探究发生的缘由并且研究诊断途径。关键词：发动机；丰田卡罗拉；电控系统；故障；诊断ⅠⅠ英文摘要ABSTRACTAt present, Hyundai Motor has become a mechanical, electrical and hydraulic integration of high-tech, in which the engine electronic control technology has matured, as a high-tech carrier features more and more obvious. Automotive engine electronic control system as the core component of the car, equivalent to the heart of the car, the normal operation of the car to go to the need to maintain the automotive electronic control system, so for each car, the various parts of the car are electronic control system Command, and its performance directly affect the reliability, safety, power, economy, emissions purification and comfort, but compared with the carburetor-type engine, electronic control engine is relatively more complex, electronic control system failure and more With abstract, to bring a certain degree of difficulty in fault diagnosis, so people in the maintenance of electronic control eng...
