Ungahlola kanjani inzwa ye-camshaft BMW E39
Okuqukethwe
Ukuhlola isimo nokushintsha inzwa ye-camshaft position (CMP)
Ukuhlola isimo nokushintsha inzwa ye-camshaft position (CMP)
Ukwenza inqubo elandelayo kungase kubangele iphutha le-OBD ukuthi ligcinwe kumemori, ezokhanyiswa isibani esiyisixwayiso sokuthi "Hlola Injini". Ngemva kokuphothula ukuhlolwa nokululama ngokufanele, ungakhohlwa ukusula inkumbulo yesistimu (bheka isigaba se-On-Board Diagnostic (OBD) - isimiso sokusebenza kanye namakhodi wephutha).
Amamodeli ka-1993 no-1994
Inzwa ye-CMP isetshenziselwa ukunquma isivinini senjini kanye nendawo yamanje yamapiston kumasilinda awo. Ulwazi olurekhodiwe luthunyelwa kuphrosesa eyakhelwe ngaphakathi, okuthi, ngokusekelwe ekuhlaziyeni kwayo, enze izinguquko ezifanele ubude besikhathi somjovo kanye nezilungiselelo zesikhathi zokubasa. Inzwa ye-CMP iqukethe ipuleti le-rotor kanye nesekethe ekhiqiza isignali yamaza. Ipuleti ye-rotor ihlukaniswe ngama-grooves wezigaba ze-360 (ngokunyuka kwe-1). Ukuma nendawo yezikhala kukuvumela ukuthi ulandelele isivinini senjini nendawo yamanje ye-camshaft. Isethi yokukhanya nama-photodiode ihlanganiswe kumjikelezo wokwakheka. Njengoba amazinyo e-rotor edlula isikhala phakathi kokukhanya ne-photodiode, ukuphazamiseka okulandelanayo kwe-beam yokukhanya kwenzeka.
Nqamula isixhumi sezintambo zezintambo kumsabalalisi. Vula i-ignition. Usebenzisa i-voltmeter, hlola itheminali emnyama nemhlophe yesixhumi. Uma ingekho i-voltage, hlola isimo sezintambo kusekethe phakathi kwe-ECCS edluliselwe nebhethri. (ungakhohlwa amafuse). Bheka futhi isimo sangempela se-relay kanye ne-electroconducting esuka kuyo iye kusokhethi sokusabalalisa (Amasu okuxhumana kukagesi ekugcineni kweNhloko bheka okokusebenza kukagesi okuku-Onboard). Sebenzisa i-ohmmeter ukuze uhlole itheminali yentambo emnyama ukuze uthole umhlabathi.
Cisha ukuthungela bese ukhipha umsabalalisi wenjini (impahla kagesi yenjini bheka iNhloko). Buyisela uxhumo lwezintambo lwangempela. Xhuma intambo ephozithivu ye-voltmeter kutheminali eluhlaza/emnyama ngemuva kwesixhumi. Gcwalisa ukuhlolwa okunegethivu kuholela emhlabathini. Vula i-ignition futhi uqale kancane ukuguqula i-shaft yokusabalalisa, ubukele i-gauge yokucindezela. Kufanele uthole lesi sithombe esilandelayo: 6 ukweqa nge-amplitude engu-5,0 V ngenguquko ye-shaft ngayinye ngokumelene nesizinda sesignali esekelwe ku-zero. Lokhu kuhlola kuqinisekisa ukuthi isignali 120 ibhaliswe ngendlela efanele.
Uma ukucisha kuvaliwe, xhuma i-voltmeter kutheminali yentambo ephuzi-luhlaza. Vula i-ignition bese uqala kancane ukuguqula i-shaft yokusabalalisa. Lesi sikhathi kufanele kube nokuqhuma okuvamile kwama-volts angu-5 ngemvamisa ye-360 pcs nge-revolution ye-shaft. Le nqubo iqinisekisa ukuthi isignali 1 yenziwe ngendlela efanele.
Emiphumeleni engemihle yokuhlolwa okuchazwe ngenhla komhlangano womsabalalisi wokushisa (imishini kagesi yenjini bheka iNhloko) ingashintshwa, - inzwa ye-CMR ayikho ngaphansi kwesevisi ngayinye.
Amamodeli kusukela ngo-1995 mayelana.
Inzwa ye-CMP itholakala kukhava yesikhathi ngaphambili kweyunithi yamandla. Inzwa iqukethe uzibuthe ongunaphakade, umgogodla kanye ne-wire winding futhi isetshenziselwa ukuthola ama-grooves ku-sprocket ye-camshaft. Njengoba amazinyo e-sprocket edlula eduze kwenzwa, inkambu kazibuthe ezungezile iyashintsha, yona ibe amandla okukhipha isignali we-PCM. Ngokusekelwe ekuhlaziyweni kolwazi oluvela kunzwa, imojula yokulawula inquma indawo yama-piston kumasilinda awo (TDC).
Nqamula izintambo zenzwa. Usebenzisa i-ohmmeter, kala ukumelana phakathi kwamaphini amabili wesixhumi senzwa. Emazingeni okushisa angama-20 C, kufanele kube nokumelana kwe-1440 ÷ 1760 Ohm (inzwa eyenziwe yi-Hitachi) / 2090 ÷ 2550 Ohm (inzwa eyenziwe yi-Mitsubishi), inzwa engalungile kufanele ishintshwe.
Uma umphumela walokhu kuhlolwa okungenhla uthi positive, bheka imidwebo yokuxhunywa kukagesi (bheka I-Head On-board) kagesi bese uhlola izintambo zikagesi ezivela ku-PCM ukuze uthole izimpawu zokunqamuka. Hlola izimpawu zomhlabathi omubi ocingweni olumnyama lwehhanisi lokufaka izintambo (sebenzisa i-ohmmeter). Uma inzwa nezintambo zilungile, yisa imoto esitolo sokulungisa i-PCM uma kunesidingo.
Inzwa yesimo seCamshaft
Ngine-BMW E39 M52TU ye-1998 eneminyaka emibili. Konke kuzolunga, kodwa sengikhathele kakade ukwephula inzwa ye-camshaft position. Kule minyaka emibili, manje sengithenga inzwa yesithupha. Ngithenga inzwa, ngishayela izinyanga ezingu-1-2, ihluleka, kanti enye i-hedgehogs engu-1-2 enephukile. Ngithenge kokubili okwangempela, njengesihogo, kanye ne-bu yoqobo, nezinye izinkampani zibiza eyodwa, izinyanga ezimbili futhi ungaya entsha. Ku-inthanethi babhala ama-breakdowns kuphela noma ukuthi bangabheka kanjani ukuthi yini engasebenzi, kodwa akekho obhala ukuthi kungani ihluleka. Ubani ongasiza? Ukumba kuphi? Ingabe kungenxa kaVanus?
Yebo, ngikhohliwe ukucacisa ukuthi inzwa ye-camshaft yokungenisa
Qala ngamandla Iyini inzwa ye-crankshaft noma i-camshaft? Ikhoyili ye-induction evamile. Uma usha, bheka ukudla. I-XM ngine-Chinese evamile kanye no-1 no-2. Konke kuyasebenza.
Ngaya kwabasebenza ngogesi, ngacabanga ukuthi bangase baqhamuke nokuthile. Mhlawumbe uhlobo oluthile lwe-damper noma into enjalo. Abazange basize, bathi cishe kuzodingeka babheke isakhi sofuzo, isimo samabhulashi. Futhi hlobo luni lokuthopha okucasulayo olukhona olusebenzayo noma kunjalo, ngokuvamile ngemva kwalokho ubuchopho buqala ukuqhuma
Ukuhlola i-generator kulula. Thatha imitha ye-voltage ye-LCD evamile (yaseShayina) bese uyibeka ku-othomathikhi ukuze ubone ama-voltage spikes. Intengo yokukhishwa imayelana nama-ruble ayi-100. Kufanele kube 14-14,2
Ngisanda kushaya amakhoyili amabili ngempelasonto edlule. Kokunye - ukumelana, kubo bonke othintana nabo - okungapheli, okungukuthi, igebe. Okwesibili, kuphela eluhlaza kanye nensundu kwakukhona ukumelana, kodwa izikhathi ezingu-10 ngaphezu kwalokho okufanele kube khona, futhi ngokubomvu kwakukhona negebe. Futhi njalo kukhoyili efanayo. Sengicabanga ukuthi mhlawumbe lokhu kungenxa yokuthi ngisebenzisa ikhebula emzimbeni wofuzo. Mhlawumbe kunohlobo oluthile lwezibuthe ezisebenza lapha. Nakuba lapho ikhebula lifushane futhi kunzima ukulilungisa ngendlela ehlukile. Futhi nansi inzwa yesithupha. Esikhathini esizayo esiseduze ngizobiza lokho okufanelekile futhi ngizame ukubeka ucingo lwekhoyili entsha ngandlela-thile eduze nomnyango, hhayi ku-gene. Futhi i-voltage ikalwa ngokuqondile kufuzo noma ingaba ku-Akum?
Yebo, kunegebe kunzwa ngokwayo. Angiqondi kahle ukuthi lokhu kuzonginika ini, futhi anginaye osebenza ngogesi, ngakho ngizokwenza ngaphandle kwemibuzo, kodwa ngitshele ukuthi ngingayithola kuphi iphinikhodi ye-chip ye-ECU.
Phakathi komlenze woku-1 nowesi-2 ku-"baba" wenzwa kufanele kube cishe ama-ohms angu-13, phakathi kwe-2nd ne-3rd mayelana nama-ohms ama-3. (kwezinye izinzwa babhala izinombolo zemilenze, kwezinye abazibhala)
Khona-ke uzokwazi ukuthi inzwa ngokwayo ayifinyeziwe.
Ngikala inzwa koxhumana nabo ngokwedlulele 5,7, shintsha i-polarity, i-3,5 iyaboniswa. Phakathi kwe-10.6 yokuqala nemaphakathi uma ushintsha i-polarity, bese kuba yi-infinity. Phakathi kwendawo ephakathi nendawo yokugcina engu-3,9, uma ushintsha i-polarity, khona-ke i-infinity. Indlela yokuqonda lapho oxhumana naye ekhona?
Abheke phezulu abheka amacebo ku-e39, awatholanga lutho. Inzwa ingase ibe isixhumanisi esibuthakathaka kumjikelezo wakho, kodwa angikwazi ukuthola ukuthi ihamba kuphi noma kanjani.
Uyibheka kanjani inzwa ye-camshaft bmw e39
Ngosuku “oluhle” “ama-samurai” ami ayengafuni ukuqala okokuqala, nakuba aqala ngaphandle kwezinkinga emzamweni wesibili (lokhu kwase kuwukuthinta kancane ukunaka kwami ezweni lami)
Ngemva kohambo olufushane (ukufudumala), ngabona ngokushesha ukuthi imoto yaba ivila - ishesha kancane, isabela kabi kugesi, ishayela kancane noma ngaphansi kuphela ngemva kuka-2500-3000 rpm, kwaba khona ukwehluleka ngesikhathi sokusheshisa, umsindo wenjini waba Ngalesi sikhathi, isivinini esingu-XX sasizinzile futhi sijwayelekile, kwakungekho ama-twitches endleleni, awekho amaphutha ngokulandelana.
Ngixhume i-INPU futhi isigebengu sivele enjinini ye-ECU: iphutha 65, inzwa ye-camshaft.
Nganquma ukuyishintsha ngokwami, ngathenga inzwa ye-VDO esitolo esithembekile, njengoba eyangempela yayingekho, futhi nomthengisi ofanayo wathi i-VDO yayiyiyokuqala, kodwa ine-logo ye-BMW nasebhokisini.
Nginqume ukwenza okunye esikhundleni njengakuvidiyo engezansi, lapho, ngendlela, umfana wasebenzisa inzwa ye-Meile.
Ngaphambi kokufaka inzwa, kunengqondo ukuvumela injini iphole, ngaphandle kwalokho ukugibela ngaphansi kwe-hood akulungile futhi kuyacindezela!
- Susa ikhava yenjini efanele
- Nqamula ishubhu le-vent ku-Vanos:
- Sinqamula isixhumi (chip) ku-Vanos solenoid, esithombeni sikhonjiswa umcibisholo oluhlaza okwesibhakabhaka:
- Ngokucophelela (ngaphandle kokushiseka ngokweqile) khumula i-Vanos solenoid ngesikrufu esivulekile esingu-32:
- Khumula ngokucophelela ipayipi elingaphansi ku-Vanos valve nge-wrench engu-19, ubambe iwasha endaweni ekhonjiswe umcibisholo kanye nebhawodi ngesinye isandla, bese uthatha ipayipi elingakulungi uwubeke eceleni: Ukuze kube lula, ungakwazi ukukhulula isihlungi samafutha. (Angikwenzanga lokhu)
- Manje ukufinyelela inzwa sekuvuliwe, khumula ibhawodi lenzwa nge-“torx” (ngiyiqaqe ngehexagon) bese ubamba ibhawudo ukuze ungaboni!
- Susa inzwa kusokhethi (amafutha amaningi azothululwa)
- Nqamula isixhumi senzwa, kulula ukusithola
- Susa ngokucophelela i-o-ring kusuka kunzwa futhi, ngemva kokuyigcoba ngamafutha amasha, yifake kunzwa entsha.
- Faka inzwa "kusokhethi", xhuma inzwa "chip" bese uqinisa ibhawudi lokukhweza inzwa.
- Gcoba indandatho ye-Vanos solenoid O-ring ngamafutha amasha bese uyifaka ngokuhlehlayo.
- Sixhuma isithwebuli bese sisetha kabusha iphutha lenzwa kumemori
Izengezo namanothi:
- kimi mathupha, okunzima kakhulu (futhi isikhathi eside) kwakuwukunqamula bese uxhuma isixhumi senzwa ngokwayo, ngasindiswa yiqiniso lokuthi nginezandla ezincane hhayi iminwe emikhulu, futhi noma kunjalo ngahlupheka!
Uma isihlungi sisusiwe kungaba lula kakhulu. - inzwa ye-VDO engeyona eyangempela ayihlukile kunenzwa ye-BMW yasekuqaleni: bobabili bathi Siemens kanye nenombolo engu-5WK96011Z, bavele bengeze ilogo ye-BMW kweyokuqala.
- ngemva kokufaka inzwa, ukusheshisa kanye namandla enjini jikelele kuthuthuke kakhulu, ngithemba ukuthi lokhu kuzoqhubeka nokuba njalo.
Uyibheka kanjani inzwa ye-camshaft bmw e39 m52
Ngenkathi ngibona ukuthi inkinga ikuphi, ngathola abantu abanezinkinga ezifanayo, lokhu okuthunyelwe kungokwabo.
Izimpawu zazimi kanje: ukukhala komjovo, ubuthuntu ngezansi, ukudlidliza ngokungenzi lutho, ukusetshenziswa kwanda ngo-20%, ingxube ecebile (ipayipi, i-lambda kanye ne-catalyst ayinuki).
QAPHELA! Izimpawu zijwayelekile kuphela ezinjinini ze-M50 2l ezinomjovo we-Siemens kanye ne-M52 kufika ku-98 kuya phambili, mhlawumbe kumamodeli akamuva, angikwazi ukusho abanye.
Ngixhume i-INPA, ngikhomba i-DPRV, ngibheke idatha yayo, kubonakala sengathi ayikhonondi.
Ngisuse inzwa, ngihlolwe nge-ohmmeter phakathi kuka-1 no-2 oxhumana nabo kufanele kube ngu-12,2 Ohm - 12,6 Ohm, phakathi kuka-2 no-3
0,39 ohm - 0,41 ohm Nginegebe eliphakathi kuka 1 no 2. Ngakhumula intambo yezintambo, kwavela ukuthi izintambo zifile. Ngazama ukulinganisa ngqo kwinzwa, into efanayo. Ihlakaziwe, yalinganisa abathintwayo futhi yaqinisekisa ukuthi isilungile.
Ishintsha kalula kakhulu. Okwesibili ngayishintsha ngemizuzu engu-15, okokuqala ngamba imizuzu engu-40.
Uzodinga: indawo ekhanyiswe kahle, ama-wrenches (32, 19, 10 avulekile), isokhethi engu-10-intshi ene-wrench, i-screwdriver encane ye-flat-blade, kanye nokubamba izandla. Kungcono ukwenza konke ngenjini ebandayo, izandla zakho zizophepha.
