Mass Air Flow woluvo - ukujonga njani? isivamvo DMRV

MAF sensor (DMRV) iqhotyoshelwe emoyeni filter, kwaye imisela umlinganiselo womoya ukuba kudlule kubo. Ukususela kwenkcazelo eyiyo zesi salathisi kuxhomekeke umgangatho umxube ezinokutsha. Iziphene mass isivamvo ukungena komoya nangoko kuchaphazela ukusebenza injini.

zimpawu umonakalo

Xa uphawu lokuqala yaphula injini akufuneki aphakuzele, umzi ukuya evenkileni athathe DFID entsha. Kusenokwenzeka ukuba Kucetyiswa ukuba umonakalo woluvo ukungena komoya. Indlela ukuhlola umsebenzi wakhe? Okokuqala, kufuneka uphulaphule ngenyameko imoto. Uya kubonisa ukuba woluvo unjengonetyala DFID, kwaye uya kuziphatha ngolu hlobo lulandelayo:

• ikhompyutha iya kunika imposiso «Khangela injini»;

• ukunciphisa amandla;

• ukusetyenziswa ukwanda amafutha;

• kuya kuba kubi ukuqalisa injini;

• ukunciphisa isithethi.

Yintoni ayisebenzi ngokuchanekileyo ukuba woluvo ukungena komoya abaninzi? Indlela ukukhangela imo?

Option 1: Khubaza

Xa injini wayeka kunye DMRV qhawula isinxibelelanisi. Ngaba qhawula isixhobo, eli uza kuvuka imo yonxunguphalo, kunye nomxube amafutha uza kulungiswa kuthathelwa ingqalelo kwindawo yangoku umcephe wokunyusa. On utshintsho kulo imo kwakhona azise injini, kufuneka ugcine isantya phezu 1500 Rev / min. Izigqibo zokugqibela DFID iziphene angenza ntoni xa uqhuba ufumanisa ukuba iimfuno baphucuka emva woluvo icinyiwe. Qaphela: I-iinguqulelo khompyutha I-7.2 kwaye I-7.9.7 emva zokuqhawula DMRV ayinyuki isantya injini.

Option 2. Firmware

Kusenokwenzeka ukuba khompyutha sele eguqulwe yi-firmware, ngoko akucaci uya ziziphathe njani xa usebenzisa iinketho ezidweliswe apha ngentla. Kulo mzekelo, oku kwakhona ukuba sisebenze woluvo ukungena komoya abaninzi. njani khangela na? Thatha ipleyiti 1 mm ubukhulu uyifake phantsi engetelekeke umatshini. Xa phezulu speed injini, terminal Nqamla uxhulumaniso kunye DMRV. Ukuba injini iyaqhubeka ukusebenza, ngoko ke ityala elo tyala kwiyunithi yolawulo, elileli, emanyathelweni IAC. Abayi musa ukusabela kwimo zonxunguphalo ngaphandle DMRV.

Option 3: Diagnosis multimeter

Loo ngobuwena ilungele ukuba uxilongo boluvo Bosch kunye indices: 0280218004, 0280218116, kwaye 0.280.218 tester 037. Kuba imida womlinganiselo ukucwangcisa 2B, kwimo ombane rhoqo. Le iingcingo (orientation of ndlwana)

• uphawu Igalelo - yellow;

• woluvo unikezelo - engwevu ezimhlophe;

• Ground (thabatha) - eluhlaza;

• Xa relay engundoqo - epinki namnyama.

Qaphela:

Imibala ngcingo kubonisiwe ukuba ubuninzi bemizekelo, ingatshintshwa imibala, kodwa ke ixabiso izigqibo ezifanayo.

Inkqubo kumlinganiselo

Emva ucinezelo, ngaphandle kokuba injini, enze scanning. isixhobo Red ukudibanisa probe kwicingo DFID omthubi kunye antsundu eluhlaza. Ngoko ke ukubambelela kumlinganiselo ombane kunye zokuyilungisa. Ukuthelekisa ukufundwa kunye nezincomo nomenzi, kuya kuba kugwetywa yokusebenza isixhobo. DFID Elitsha V. ombane 0,996-1,01

parameters yokusebenza device, kuxhomekeke ombane:

1.01-1.03 - isivamvo functional;

1.03-1.04 - functional, kodwa ubomi woluvo esiphantse ndidiniwe;

1.04-1.05 - umthombo yaphela, ukuba uphawu akakho, unako ukuxhaphaza, kodwa lixesha ukuthenga entsha enye;

1.05 nangaphezulu - sinesiphene, kufuneka indawo.

Qaphela:

Ukuhlola woluvo ubunzima umoya flow, sinokufunda uhambo computer kwi parameters "isivamvo ombane".

Option 4: ukuhlolwa Visual

Sebenzisa screwdriver ukhulule yamasango ithumbu, relegating corrugation, ahlole woluvo kunye corrugation. Zonke iindawo kufuneka owomileyo simahla ukususela oyile kunye condensate iidipozithi. Ezibangela ungcoliseko DMRV:

• A dirty air filter;

• inqanaba oyile ingaphezulu eqhelekileyo;

• ugcwale kwesisefo, inkqubo yokungena.

Ukuyeka ezibangela ungcoliseko DFID, umele ukorekishwe kunye neziphumo, yaye oku kuya kufuna ukucoca woluvo MAF. Esebenzisa ezingundoqo 10, ngokuthi bezikhulule kunye nezitshixo nokubopha woluvo, eyahlula emoyeni lokucoca ulwelo. I woluvo kufuneka umsesane rubber ukuthintela umoya sokufunxa ekrwada. Ukuba ayikho okanye ingekho kwisayithi, igalelo njengonombombiya isixhobo uchaphazelekayo eluthulini. Oku kunokubangela woluvo ukuba kahle. ulandelelwano Ukufakwa:

• I-isixhobo yi kunxitywe uphawu gum;

• Uqinisekise umphetho uphawu;

• woluvo imvelaphi inyuselwa khona kwi izindlu lokucoca ulwelo.

Inkqubo replacement

Ukucima i ucinezelo, susa plug woluvo. Xa bezikhulule okubamba, wucime umoya owodwa. isivamvo Next ukhulule kwaye usisuse ukusuka izindlu lokucoca ulwelo. Ukuze Abakhulule kuyo, kufuneka ukuba ufake 10. Emva kokuba umbuzo yoviwo ziya kuvela kwakhona, ukuba woluvo sinesiphene mass umoya kwemali, ukuze ujonge indlela yokusebenza kwayo. Ukuhlola lokufunyaniswa imeko isixhobo, musa nje uthenge. Kufuneka ke ukuba DFID kuxabisa nemiqulu engange-1,500 ukuya 2,000. Kodwa uyakwazi ukususa nje ukungcola tirhisa ubuninzi engange-200.

Kuthethwa ukususa ezingcolisa

Ukuze ukuhlamba ngokomgangatho DFID, kufuneka zisuswe, inkqubo kokususa sele kuchaziwe ngaphambili. Ngaphakathi isixhobo kukho enemingxuma. 2-3 efakwe kuyo zincwadi Womenzi ngokohlobo ngcingo ezincinane. Ngexesha ukusebenza, malungu uyosuleleka, ekhokelela kahle. Ukunika ubomi yesibini ukuya kwisixhobo, ekucoceni umnatha kwaye utsale abenzi afanelekile cleaner isiBeki. Spray, uhlambe ngaphandle ukungcoliswa kwinxalenye engaphakathi DFID. Zalisa ukususwa ezingcolisa yenzeke okokuqala, kuya kufuneka uphinde le nkqubo. Zonke ukutshiza elandelayo kufuneka lwenziwe kuphela emva kokuba arhente yokomisa. Ngokusebenzisa ukucoca sensor ke, imibhobho kufuneka ahlole karhulumente - ubukho ubuthi ukususa kubo. Ukusetyenziswa njengendlela ngenxa yokunqanda ubumdaka evela isiBeki ibonisa ukuba 8 ka-10 emva kokuba izixhobo unyango ziqala ukusebenza kwimo echanekileyo. Kodwa kwezinye iimeko kuyimfuneko ukuthenga woluvo entsha DFID.

isiphelo

Ngoku khangela DFID ngokwayo abaya kuthathelwa ingqalelo zigqityiwe. Kwaye phezu umbuzo wokuba ingaba woluvo flow umoya ubunzima sinesiphene, ukukhangela ukuba imeko yayo, ukuze aphendule nge-100% isiqinisekiso ukuze abe nako kwizikhululo inkonzo, uphando diagnostic salwenza kunye nokusetyenziswa kwezixhobo ezizodwa.
