Dizal Injector Fuel Injector 0445120053 Bosch don Injin Dizal ɗin Mota

Akwai hanyoyi da yawa na yadda za a duba aiki na injector. Bari mu lissafa su cikin tsari tare da cikakken nuni na algorithm na ayyuka.

1. Dubawa ta hanyar auna juriya
Kuna iya duba allurar ba tare da cire su ta amfani da multimeter ba. Don farawa, bincika injectors ɗin da aka sanya akan motarka - babba ko ƙarancin ƙarfi (juriya na lantarki). Za a buƙaci wannan bayanan don yin cikakken ganewar asali. Don bincika injectors tare da mai gwadawa ba tare da cire su daga injin konewa na ciki ba, kuna buƙatar bin tsarin da ke gaba:

2. Auna juriya na iskar injector
(1) cire high-voltage wayoyi daga injectors;
saita multimeter zuwa yanayin aunawa juriya (ohmmeter) a cikin kewayon daga 0 zuwa 200 ohms (dangane da sigogin fasaha na na'urar, iyakar babba na iya bambanta, mafi mahimmanci, don ohmmeter na iya nuna ƙimar juriya da yawa dubun ohms;
(2) kashe wutan kuma cire mummunan tasha daga baturin;
cire haɗin haɗin wutar lantarki akan injector da ake ganowa (yawanci, saboda wannan, an cire hoton hawan da ke jikin toshewa);
haɗa hanyoyin gwaji na mai gwadawa zuwa masu allura da aunawa.
High impedance injectors da rufi juriya a cikin 11 ... 17 Ohm, da kuma low impedance - 2 ... 5 Ohm.

Idan ƙimar juriya mai aunawa ta bambanta sosai da ƙayyadaddun ƙimar, wannan yana nuna cewa allurar ba ta da kyau. Saboda haka, dole ne a tarwatsa bututun ƙarfe kuma a yi cikakken ganewar asali.

Ka tuna cewa lokacin bincika injectors tare da multimeter, kuna buƙatar tantance duk na'urori ɗaya bayan ɗaya! Don haka za ku iya duba wane allurar baya aiki.
Yana da mahimmanci a san cewa ana ba da wutar lantarki zuwa masu injectors daga ECU a cikin nau'in bugun jini, ba koyaushe ba. Sabili da haka, ana ba da shawarar ba kawai don auna juriya tare da ohmmeter ba, har ma don ɗaukar oscillogram na canja wurin wutar lantarki ta amfani da oscilloscope, don haka zaku iya ganin irin ƙarfin ƙarfin da yake ɗauka. Mai gwadawa zai nuna maka matsakaicin ƙimar kawai.
