I20R型发动机电子点火系统故障检测与维修摘要随着我国经济的发展,我国汽车制造企业也得到了快速的发展。发动机是汽车的核心,然而讲我系统又是发动机的重要组成部分,点火系统对于发动机工作起着至关重要的作用,良好的点火系统能够有效的降低汽车尾气的排放,同时也降低了燃油的消耗,能够使得发动机进行正常的工作。所以对于点火系统进行设计是至关重要的,这样使得系统能够正常的进行工作,具有优良的性能。汽车制造企业在对于汽车生产过程中尤其注重对于点火系统的设计。通过对点火系统进行进一步优化,能够有效的提高点火系统的性能,降低了发动机的油耗,对于汽车的生产起到至关重要的作用。然而发动机在进行使用的过程中,由于对于发动机也不够注重保养,这样很容易使点火系统不能够进行正常的工作,严重的影响着发动机的正常的使用。本文的研究的目的为:20R型发动机电子点火系统故障进行分析,并且对于故障进行维修。研究的结果:20R型发动机电子点火系统存在的主要故障为电控点火系统不工作维修、火花塞故障维修、点火线圈故障维修,所以要及时的对于20R型发动机电子点火系统进行检测和维修。关键词:发动机;点火系统;诊断IIAbstractWiththedevelopmentofChina'seconomy,China'sautomobilemanufacturingenterpriseshavealsoobtainedrapiddevelopment.Theengineisthecoreofthecar,butthesystemisanimportantpartoftheengine,ignitionsystemfortheengineworkplaysacrucialrole,agoodignitionsystemcaneffectivelyreducetheexhaustemissionsofthecar,butalsoreducetheconsumptionoffuel,canmaketheengineworknormally.Therefore,itisveryimportanttodesigntheignitionsystem,sothatthesystemcanworknormallyandhasexcellentperformance.Automobilemanufacturingenterprisespayspecialattentiontothedesignofignitionsystemintheprocessofautomobileproduction.Furtheroptimizationoftheignitionsystemcaneffectivelyimprovetheperformanceoftheignitionsystemandreducethefuelconsumptionoftheengine,whichplaysacrucialroleintheproductionofautomobiles.However,intheprocessofusingtheengine,duetothelackofattentiontothemaintenanceoftheengine,itiseasytomaketheignitionsystemcannotworknormally,whichseriouslyaffectsthenormaluseoftheengine.Thepurposeofthispaperistoanalyzeandrepairthefaultsofelectronicignitionsystemof20Rengine.Researchresults:themainfaultsoftheelectronicignitionsystemofthe20Renginearethenon-workingmaintenanceoftheelectronicignitionsystem,thefaultmaintenanceofsparkplugandthefaultmaintenanceoftheignitioncoil.Therefore,theelectronicignitionsystemofthe20Rengineshouldbetestedandrepairedintime.Keywords:engine;Ignitionsystem;Thediagnosis目录摘要........................................................................................................................IAbstract.....................................................................................................................II第1章绪论..............................................................................................................11.1课题背景、目的和意义.............................................................................11.2国内外研究现状.........................................................................................11.3研究内容.....................................................................................................2第2章发动机电子点火系统概述..........................................................................42.1电子控制点火系统的基本组成和分类.....................................................42.2电子点火系统结构特点.............................................................................52.3电子点...
