/毕业设计(论文) 常州机电职业技术学院毕业设计（论文）系 部： 车辆工程系 专 业： 汽车检测与维修 题 目： 电控发动机故障诊断与分析 2025 年 5 月 毕业设计（论文）中文摘要 汽车电控发动机是电子技术与汽车技术的完美结合，电控技术能够提高发动机的动力性、燃油经济性、加速性能和起动性能。所以，对于电控系统的结构认识和故障诊断就显得十分重要。 本文首先是对电控系统的组成（信号输入装置、电子控制单元和执行元件）进行总体论述，接下来由于应用在发动机上的子控制系统尤以电控燃油喷射新系统较为复杂难懂，所以本文对其结构和工作原理进行了详尽阐述；还有对其辅助控制系统（怠速控制系统、排放控制系统和故障自诊断系统）也加以补充；最后是对汽车电控发动机控制系统故障诊断与方法分析。 关键词：电控发动机 控制系统 故障分析与检测毕业设计（论文）外文摘要Title：Fault diagnosis and analysis of electronic control engineAbstract：Auto electronic control engine is the combination of electronic technology and vehicle technology perfect, electronic control technology can improve the engine power, fuel economy, acceleration performance and the starting performance. So, it is very important for understanding structure and fault diagnosis of electronic control system. This paper is composed of electronic control system (signal input device, electronic control unit and actuator) to the general discussion, then the application in the engine electronic control system, especially in the electronic fuel injection system is more complicated, so this paper elaborates on the structure and the working principle and control system of the auxiliary; (idle speed control system, emission control system and fault diagnosis system) has to be added; the last is the most practical method is to control the engine fault diagnosis and analysis system of automotive electronic control, column. Keywords: electronic control engine control system fault analysis and diagno...
