摘 要
汽车新技术发展十分迅速，在汽车工程上的应用越来越普遍．而相关高校及社会技术培训机构在汽车新技术教学中大多以理论为主，相应新技术、新结构为主的实践教学手段严重滞后，不仅不能与汽车领域广泛推出的汽车新技术同步，更跟不上汽车新技术的快速发展．为此，研制了丰田1ZZ—FE型电控发动机仿真实验台，希望能够为相关教学机构提供有益的帮助结合我校丰田技术人才培养的要求，本设计以丰田花冠1ZZ-FE发动机为蓝本，设计制造出具有故障诊断以及教学功能演示的综合实验台，可以结合实验台可以进行故障设置，诊断并且进行信号测试，数据流分析等。
本设计主要是针对丰田1ZZ-FE发动机进行展开，首先介绍了1ZZ-FE发动机的内部结构、工作原理及运行情况。在此基础上，提出了一种以教学为目的的发动机实验台设计方案。针对它的教学目的，该实验台的特点是结构相对较为简单，实验台设有检测端子和自诊断接口，便于在教学过程中，让学生直
观了解并通过设置故障增强其动手能力，以达到良好的教学效果。

ABSTRACT
Automobile new technology is developing very rapidly, and the application in automobile engineering is becoming more and more common. And the related universities and technical training institutions in society with new technology in the teaching theory, corresponding most of new technology, new structure of practice teaching, not only means lag in auto field widely launch new technology synchronization of the car, car more with the rapid development of new technology is developed. Therefore, Toyota 1ZZ-FE type electronic-controlled engine simulation platform, hopes to provide relevant teaching organization with our good help of Toyota technology training requirement, the design with Toyota corolla 1ZZ - FE, design and manufacture of engine with fault diagnosis and the function of teaching demonstration experiment platform, can be combined experimental fault diagnosis can be set, and signal test, data flow analysis, etc.
The design is mainly directed against Toyota 1ZZ-FE engine to start, first of all introduced the 1ZZ-FE engine 's internal structure, working principle and operation. On this basis, a teaching of the engine for the purpose of test-bed design. For the purpose of teaching it, the test-bed structure is characterized by relatively simple test-bed has a detection terminal and self-diagnostic interface to facilitate the process of teaching to enable students to understand and intuitive fault by setting the hands to strengthen their capacity in order to achieve good teaching effectiveness.
