【摘要】 本论文详细介绍了电喷发动机电控系统部件动态测试系统的研究和试制。在系统地分析了发动机电控系统的组成、结构与工作原理的基础上,设计制成时代超人2000发动机M3.8.2电控系统电路LED动态显示电路和电路故障模拟电子处理单元。根据M3.8.2电控单元电路连接器设计制成输入/输出电子控制检测端子,并在检测面板上布置了OBD-Ⅱ诊断插座和燃油压力表。使该动态测试系统能实现对电喷发动机的燃油系统、直接点火系统、怠速控制系统和燃油蒸气排放控制系统的动态检测;并通过OBD-Ⅱ诊断座、ECU输入/输出检测端子和故障模拟处理单元实现对电喷发动机电控系统各传感器、电控单元、执行器进行故障码读取与清除;动态数据读取和波形测试和故障模拟等。此外,本论文还分析了传感器和执行器典型故障波形。

【Abstract】 This paper discusses the designing and making of the dynamic testing Systems of engine electronic control system .base on the construction and operation principle of Santana 2000GSi M3.8.2 engine electronic Control Systems, design and manufacture LED circuit of dynamic testing and fault imitating electronic control unit .on the inspect board ,design and equip with Motronic 3.8.2 ECU I/O measuring joints , design and set up OBD- II diagnostic communication link, design and install fuel pressure inspecting meter .depend on the OBD- II diagnostic communication link and ECU I/O measuring joints, this dynamic testing system can inspect engine electronic fuel injection system ,distributorless ignition system ,idle speed control system and evaporative emission control system, and can inspect M3.8.2 sensors ,ECU and actuators , and can interrogate fault memory and erase fault memory; and can analyse data stream ;and can carry out fault imitating .besides, this paper analyses sensors and actuators typical fault waves.
