标致307电子燃油喷射系统的诊断与维修

河南工业职业技术学院摘要现代工业的不断发展，电控燃油喷射系统也有了很好的发展基础。电控燃油喷射系统的作用取决于控制系统，而控制系统主要由传感器、控制器和执行器组成。控制系统的复杂程度直接导致现代汽车维修作业的困难性。汽油机能正常起动必须具备四个要素：足够的点火高压与能量；恰当的混合气空燃比；正确的点火正时；正常的气缸压缩压力。大部分的汽车发动机故障维诊断则是围绕这几个方面，逐一检查！汽车维修作业离不开仪器，现代汽车维修需要精确的维修数据，而要让这些数据起作用的就只有精准的仪器.本文主要介绍标致307电子燃油喷射系统的基本组成，工作原理，详细的介绍了标致307电子燃油喷射系统的诊断与维修。关键字：标致307，电子燃油喷射系统，诊断与维修河南工业职业技术学院2AbstractThedevelopmentofmodernindustry,electronicfuelinjectionsystemisalsoaverygoodbasefordevelopment.Electronicallycontrolledfuelinjectionsystewasdependentonthecontrolsystemandcontrolsystemconsistsofsensors,controllersandactuatorscomposition.Thecomplexityofthecontrolsystemdirectlyledtothemoderndifficultyofvehiclemaintenanceoperations.Functionofthenormalstartofgasolinemusthavefourelements:fireenoughpressureandenergy;therightmixtureofair-fuelratio;thecorrectignitiontiming;normalcylindercompressionpressure.Mostoftheautomobileenginefaultdiagnosisiscentereddimensionoftheseaspects,onebyonecheck!Vehiclemaintenanceoperationscannotdowithoutequipment,vehiclemaintenanceneedsofthemodernaccuratemaintenanceofdata,andmakethesedataareonlyaccuratefunctioningequipment.Inthispaper,thePeugeot307electronicfuelinjectionsystem'sbasiccomponents,workingprinciple,describedindetailPeugeot307electronicfuelinjectionsystemdiagnosisandrepairKeywords:Peugeot307，Electronicfuelinjectionsystem，Diagnosisandrepair河南工业职业技术学院3目录1概述------------------------------------------------------------------------------------------------51.1标致307的简介-------------------------------------------------------------------------------------------51.2标致307电子燃油喷射系统-------------------------------------------------------------------------51.2.1电子燃油喷射系统介绍-----------------------------------------------------------------------51.3电控燃油喷射系统概述----------------------------------------------------------------------------------71.3.1汽油喷射系统的发展----------------------------------------------------------------------------71.3.2电控燃油喷射系统的优点----------------------------------------------------------------------72电控燃油喷射系统的基本组成及其功能---------------------------------------------------92.1进气系统-----------------------------------------------------------------------------------------------------92.2燃油供给系统--------------------------------------------------------------------------------------------102.3电子控制系统--------------------------------------------------------------------------------------------113标致307燃油供给系统主要元件的构造诊断与维修--------------------------------153.1电动汽油泵的检修------------------------------------------------------------------------------------153.1.1电动汽油泵的工作过程---------------------------------------------------------------------153.1.2电动汽油泵的检测---------------------------------------------------------------------------163.1.3使用注意事项---------------------------------------------------------------------------------163.2喷油器的检修------------------------------------------------------------------------------------------173.2.1喷油器不密封故障的检修------------------------------------------------------------------173.2.2喷油压力不正常故障的检修---------------------------------------------------------------173.2.3喷射质量差故障的检修---------------------------------------------------------------------183.3油压调节器检修---------------------------------------------------------------------------------------183.4怠速控制阀的检修------------------------------------------------------------------------------------183.4.1就车检查----------------------------------------------------------------------------------------193.4.2怠速控制阀的阻值：------------------------------------------------------------------------203.4.3拆下怠速控制阀并检查工作情况：-----------------------------------------------------203.5燃油喷射系统维修诊断技巧----------------------------------------------------------------------214标致307电子燃油喷射系统的常见故障诊断-----------------------------------------234.1发动机故障---------------------------------------------------------------------------------------------234.1.1启动困难----------------------------------------------------------------------------------------234.1.2发动机失速------------------------------------------------------------------------------------234.1.3发动机怠速粗暴或喘振---------------------------------------------------------------------234.2油泵故障------------------------------------------------------------------------------------------------244.2.1油泵不转或不泵油---------------------------------------------------------------------------244.2.2油泵转动但不泵油---------------------------------------------------------------------------254.2.3泵油压力过低---------------------------------------------------------------------------------254.2.4泵油压力过高---------------------------------------------------------------------------------254.3燃油嘴故障---------------------------------------------------------------------------------------264.3.1燃油喷嘴不喷油------------------------------------------------------------------------------264.3.2燃油喷嘴漏油---------------------------------------------------------------------------------264.3.3冷启动喷嘴不工作---------------------------------------------------------------------------27河南工业职业
