摘要
随着我国汽车保有量的大幅度上升,高新技术产品和装置在汽车上的不断引入和普及与汽车维修业高素质从业人员不足之间的矛盾显得日益突出。发动机电控技术是汽车专业的一门核心技术,理论性与实践性很强。开发发动机电控系统模拟教学实验台,能便于学生认识和学习发动机电控系统的工作原理。发动机电控系统模拟实验台可以广泛应用于科研、教学等方面,通过对发动机工作过程的模拟、显示,可以提高汽车从业人员的知识掌握水平及实际操作能力,增强对汽车电控系统的认识和掌握,为学生学习和掌握发动机电控系统的工作原理提供帮助。
本设计是以教学展示为前提,主要介绍了发动机电控系统的控制内容、发展简史与前景、组成与工作原理,并在此基础上设计电控系统模拟实验台的相关内容。主要包括实验台架的设计、电控系统的零部件布置、电动机转速控制等内容。这个教学实验台能够演示发动机的起动和正常工作过程,并且设置了测量点。通过完成对实验台的设计,可以深刻理解和掌握发动机电控系统的组成和工作原理、机械设计与机械制图的相关知识,最终设计出一款及机械、电控于一体化的产品。

ABSTRACT
With significant increase of the number of automobile,the contradiction between high-tech products and devices, the constant introduction in the car and popularization of high-quality vehicle maintenance trade and lack of practitioners e increasingly prominent. Engine electronic control technology is the theoretical and practical of a core technology and theoretical and practical very strong. Electronic control system simulation teaching test can make students to understand and learn the engine electronic control system works easy. Engine electronic control simulation system can be widely used in scientific research, teaching, etc. By displaying of the course of the engine simulation process, it can be employed to improve motor vehicle mastery level of knowledge and practical ability, and enhance the automotive electronic control system of understanding and mastering, for the students to learn and master the engine control system works to help.
The design is based on the premise of teaching show, this paper introduces control content system of the engine electronic control, brief history of and prospects for de
