Ihame nigeragezwa rya moteri yimodoka ikwirakwiza ikirere

Icyuma gikwirakwiza ikirere （MAF）, kizwi kandi nka metero yo gutembera mu kirere, ni kimwe mu bikoresho byingenzi bya moteri ya EFI.Ihindura umwuka uhumeka mukimenyetso cyamashanyarazi ikohereza mubice bya elegitoroniki (ECU).Nka kimwe mu bimenyetso byibanze byo kugena lisansi, ni sensor ipima umwuka winjira muri moteri.YASEN nuyoboye MAF sensor ikora china.

Icyuma gikwirakwiza umwuka (MAF) gishyirwa hagati yo kuyungurura ikirere hamwe no gufata ibintu byinshi kugirango bipime ubwiza bwinjira muri moteri.ECM ibara ubugari bwa lisansi yubugari nuburinganire bwibanze bwo gutwika bishingiye ku kimenyetso cya MAF.

Umuyaga ushyushye-umuyaga mwinshi （MAF）

Umuyoboro ushyushye wumuyaga mwinshi (MAF) sensor ya sensor igizwe na sensor, module yo kugenzura hamwe ninsinga ihuza ibindi bice byombi.Rukuruzi isohora DC voltage yamashanyarazi ya banki kuri module igenzura amashanyarazi (ECM), amplitude yayo ikaba ihwanye nubunini bwumwuka wa moteri.

Imiterere shingiro yumurongo wogukoresha ibyuma bishyushye bigizwe na platine ishyushye ya platine (insinga zishyushya amashanyarazi) yunvikana ikirere, irwanya indishyi yubushyuhe (insinga ikonje) ikosorwa ukurikije ubushyuhe bwikirere bwinjira, ikibaho cyumuzunguruko utagira umugozi igenzura imiyoboro ya wire ishyushye kandi ikabyara ibimenyetso bisohoka, hamwe nigikonoshwa cyumuyaga uhumeka nibindi bice.

Nyuma yo gufungura icyerekezo cya sensor ya moteri, insinga ya platine ishyushye kandi ikabyara ubushyuhe.Iyo umwuka unyuze muriyi nsinga, gukonjesha insinga zishyushye bihuye nubunini bwo gufata umwuka.ECM igumana ubushyuhe bwinsinga zishyushye zihoraho mugucunga umuyaga unyura mumashanyarazi ashyushye, kugirango umuyaga uhwanye numubare woguhumeka, mugihe ECM ishobora gupima ubwinshi bwimyuka ihumeka mugutahura ingufu zitanga ingufu.

Ibiranga ibyuma byoguhumeka ni ubunini buto, uburemere bworoshye, gusoma no kwerekana neza gusoma, kwizerwa cyane, ntabwo bigira ingaruka kumashanyarazi yo hanze, no kurwanya inkuba.

Ikintu kidakwiye no gusuzuma ibyuka bihumeka

Amakosa yimyuka yo mu kirere (MAF) agabanijwemo ibyiciro bibiri.Imwe ni uko ikimenyetso kirenga intera yagenwe, byerekana ko sensor yumuyaga yananiwe.Ibinyabiziga bigezweho bigenzurwa na elegitoronike bifite imikorere yo kurinda kunanirwa.Iyo ikimenyetso cya sensor cyananiranye, igikoresho cya elegitoroniki (ECU) kizagisimbuza agaciro gahamye, cyangwa gusimbuza ibimenyetso bya sensor ikosa hamwe nikimenyetso cyibindi bikoresho.Nyuma ya sensor ya MAF yananiwe, ECU iyisimbuza ibimenyetso bya trottle imyanya.Ibindi bibazo nibimenyetso bidahwitse (ni ukuvuga imikorere ya drift).Ikimenyetso cyimyuka idahwitse irashobora kuba mbi cyane nka salmosan azamethiphos kuruta nta kimenyetso.Kubera ko ikimenyetso kitarenze igipimo cyagenwe, ishami rya elegitoroniki (ECU) rizagenzura ingano yatewe na peteroli ukurikije iki kimenyetso cy’imyuka idahwitse, bityo, imvange izaba yoroheje cyangwa ikungahaye cyane.Niba nta kimenyetso cyerekana umwuka, ECU izakoresha ikimenyetso cya trottle position sensor aho, kandi umuvuduko wubusa wa moteri urahagaze neza.

Iyo ibimenyetso byerekana ikirere byananiranye, ibintu nyamukuru byananiranye ni ingorane zo gutangira, kudakora neza, kwihuta gukabije, gukoresha peteroli no gukora nabi (EGR), nibindi. ibisubizo, sensor ihinduka nyuma yimodoka itangiye.Muri ubu buryo, ibimenyetso bya voltage agaciro byamenyekanye na sensor ya MAF bifite ihindagurika ryihuse portafilter (impinduka ndende kandi nto).ECM igenzura ubugari bwa lisansi yubugari bushingiye kuri iki kimenyetso, gitera moteri idakora.

Impamvu nyamukuru zo gutsindwa kwa MAF:

• Kwangirika kwimbere kuri sensor;
• Icyerekezo cyo kwishyiriraho nabi cya sensor (revers)
• Fungura / bigufi umuzenguruko wa sensor terminal cyangwa umurongo

Kuvura ibyuka bya firime bishyushye byangiza (MAF) sensor

Iyo amashanyarazi atangwa ari menshi cyane cyangwa hari voltage nini ako kanya, ibyuma bishyushye bya firime bishyushye byoroshye gutwika.Impamvu ituma impagarike ya voltage yumuzunguruko iba ndende cyane (irenga 16V) akenshi ni uko bateri iba yibirunga bikabije, bigabanya ubushobozi bwayo kandi ntibishobora gukurura voltage yumuriro wa generator.Kubwibyo rero, batiri ya batiri ni imwe mu mpamvu zangiza kwangirika kwa firime ishyushye.Igisubizo nugushiraho “7812” itumanaho rya terefone itatu itangiza uruziga rwimbere kumpera yimbere ya firime ishyushye.

Umwanzuro

Sensor ya MAF nibice byingenzi kumodoka, birakenewe ko abantu bumva muri make uburyo bwo gusuzuma no gukosora ibyangiritse.Mubyukuri hari byinshi mubushinwa butanga sensor nyinshi, kubindi bisobanuro, pls hamagara YASEN.
