汽车点火系统故障诊断与维修VIP免费

汽车点火系统故障诊断与维修摘要汽车工业的快速发展必将带动维修行业的前进步伐。本文则主要通过对汽车点火系统分类及结构的检测与维修和常见故障诊断与维修的方法的论述，使人们对点火系有了更深入的了解，有助于维修技师对点火系统进行快速的诊断和维修，有助于维修行业的发展。随着科学技术的不断发展，汽车的技术也有了巨大的发展，大量地使用电子元件以及利用计算机监控汽车的运转。而汽车发动机的点火系也有了很大的变化：从传统点火系到电子点火系，再发展到无分电器的独立点火系统,而其中的无分电器的独立点火系统又分为DFS（双火花线圈）点火系统和EFS（单火花线圈）点火系统。这些点火系统有各自的特点和结构及组成元件。关键词：汽车；点火系统；线圈；分电器；IAbstractTherapiddevelopmentofautomobileindustryisboundtoleadtorepairthepaceoftheindustry.Thisarticleismainlybasedontheclassificationandstructureofautomobileignitionsystemtestingandrepairandcommonfaultdiagnosisandrepairofthemethodsarediscussed,sothatpeopleontheignitionsystemwithmoreunderstanding,contributetotherepairtechniciantotheignitionsystemforrapiddiagnosisandrepair,helpstorepairthedevelopmentoftheindustry.Withthedevelopmentofscienceandtechnology,automotivetechnologyhasachievedgreatdevelopment,tousealargenumberofelectroniccomponentsandtheuseofcomputermonitoringvehicleoperation.Automobileengineignitionsystemalsohadtheverybigchange:fromthetraditionalignitionsystemtotheelectronicignition,andthentothedistributorlessignitionsystemofindependent,ofwhichthedistributorlessignitionsystemisdividedintoindependentDFS(doublesparkignitionsystemcoil)andEFS(singlecoilignitionsystem.).Theignitionsystemhasitsowncharacteristicsandstructureandcomponents.Keywords:Automobile；Ignitionsystem；Coil；Distributor；II目录目录第1章绪论...........................................................................11.1点火系统概述..................................................................11.1.1点火系统的发展概况......................................................11.1.2点火系统基本功能........................................................11.2点火系的作用及要求............................................................1第2章点火系统的分类及结构...........................................................32.1点火系统的分类及工作原理......................................................32.1.1传统点火系统............................................................42.1.2电子点火系统............................................................82.2点火系统的结构................................................................82.2.1蓄电池点火系统..........................................................82.2.2有触点晶体管点火系统....................................................92.2.3无触点电子点火系统......................................................9第3章点火系统的常见故障诊断及维修..................................................113.1常见故障.....................................................................113.2故障分析及排除方法...........................................................12第4章点火波形在故障诊断中的应用....................................................184.1次级点火波形的形成原理.......................................................184.2几种常见故障波形的原因分析...................................................19第5章点火系统的维护................................................................225.1主要维护任务................................................
