山东理工大学硕士学位论文摘要摘要本文介绍了中国摩托车工业迅速发展的历程，以及国内外摩托车发动机电控技术的研究现状。针对要求日益严格的摩托车排放法规，对摩托车发动机电控系统的组成和技术特点进行了分析与研究，结合中国轻骑集团生产的 K162FM 发动机，提出了四冲程摩托车发动机电控燃油喷射与电控点火技术总体方案；对四冲程摩托车发动机电控系统ECU 进行了初步研究与开发；设计了摩托车发动机匹配试验台架，并进行了四冲程摩托车发动机电控系统硬件的选配、输入/输出信号的采集和标定、喷油器流量特性试验；最后通过试验研究制取了 K162FM 型四冲程摩托车发动机喷油脉谱图和点火提前角脉谱图并进行了优化。关键词：摩托车，汽油机，电喷系统，点火系统，匹配技术I山东理工大学硕士学位论文ABSTRACTAbstractIn this paper, the rapid processes of China motorcycle industry development and the domestic andforeign research works of electronic control technology of motorcycle engine have been introduced.According to the strict motorcycle emission regulation requirements, the structure and technical characters ofelectronic control system of motorcycle engine have been analyzed and researched. The total scheme ofelectronic fuel injection and electronic control ignition technology of four-stroke motorcycle engine has beenissued based on K162FM engine produced from China QingQi Group. The electronic control ECU offour-stroke motorcycle engine has been primarily researched and developed. The matching test platform ofmotorcycle engine has been designed and the hardware selection of electronic control system of four-strokemotorcycle engine and the input and output signals collection and identification and the flow test of injectorshave been finished. At last, through experiment the fuel injection and ignition MAP of K162FM four-strokemotorcycle engine have been reached and optimized.Key words: Motorcycle，Gasoline Engine，Electronic Fuel Injection System，Ignition System，MatchingTechnologyII山东理工大学硕士学位论文ABSTRACT目录第一章绪论……………………………………………………………………………011.1 引言………………………………………………………………………………011.2 新排放法规与石油短缺对摩托车电控技术的推动……………………………021.3 国内外研究现状…………………………………………………………………051.4 电控技术的应用和发展…………………………………………………………061.5 本文的主要工作…………………………………………………………………07四冲程摩托车发动机电控系统总体方案确定………………………092.1 四冲程摩托车发动机电控系统组成与原理……………………………………092.2 摩托车发动机电控燃油喷射方式选择…………………………………………092.3 摩托车发动机电控燃油喷射系统控制方法……………………………………102.4 摩托车发动机电控点火系统方案………………………………………………112.5 四冲程摩托车发动机电控单元总体方案………………
