Momwe mungayang'anire sensor ya camshaft BMW E39

Kuyang'ana momwe zinthu zilili ndikusinthira camshaft position sensor (CMP)

Kuyang'ana momwe zinthu zilili ndikusinthira camshaft position sensor (CMP)

Kuchita zotsatirazi kungapangitse kuti vuto la OBD lisungidwe mu kukumbukira, lomwe lidzawunikiridwa ndi nyali yochenjeza ya "Check Engine". Mukamaliza kuyesa ndikuchira moyenera, musaiwale kufufuta kukumbukira kwadongosolo (onani gawo la On-Board Diagnostic (OBD) - mfundo yoyendetsera ntchito ndi zolakwika).

1993 ndi 1994 zitsanzo

Sensa ya CMP imagwiritsidwa ntchito kudziwa kuthamanga kwa injini komanso momwe ma pistoni alili m'masilinda awo. Zomwe zimajambulidwa zimatumizidwa ku purosesa yomangidwa, yomwe, kutengera kusanthula kwake, imapanga zosintha zoyenera pa nthawi ya jakisoni komanso nthawi yoyatsira. Sensa ya CMP imakhala ndi mbale yozungulira komanso mawonekedwe opangira mafunde. Mbale ya rotor imagawidwa m'magulu a magawo 360 (mu increments ya 1). Maonekedwe ndi malo a mipata amakulolani kuti muyang'ane liwiro la injini ndi malo omwe alipo a camshaft. Seti ya kuwala ndi ma photodiodes imaphatikizidwa mu dera lopangidwira. Pamene mano a rotor amadutsa danga pakati pa kuwala ndi photodiode, kusokoneza motsatizana kwa kuwala kwa kuwala kumachitika.

Lumikizani cholumikizira cholumikizira mawaya kuchokera kwa wogawa. Yatsani poyatsira. Pogwiritsa ntchito voltmeter, yang'anani cholumikizira chakuda ndi choyera cha cholumikizira. Ngati palibe voteji, yang'anani momwe mawaya amayendera pozungulira pakati pa ECCS relay ndi batri. (musaiwale ma fuse). Onaninso mkhalidwe wa relay ndi electroconducting kuchoka kwa icho kupita ku socket yogawa (Mapulani olumikizira magetsi kumapeto kwa Mutu zida zamagetsi za Onboard onani). Gwiritsani ntchito ohmmeter kuti muwone ngati mawaya akuda ali pansi.

Zimitsani kuyatsa ndikuchotsa wogawa injini (zida Zamagetsi za injini onani Mutu). Bwezeretsani kulumikizana kwa waya koyambirira. Lumikizani chowongolera chabwino cha voltmeter ku terminal yobiriwira / yakuda kumbuyo kwa cholumikizira. Tsimikizirani mayeso owonetsa kuti ali pansi. Yatsani choyatsira ndipo pang'onopang'ono muyambe kutembenuza shaft yogawa, kuyang'ana mphamvu yamagetsi. Muyenera kupeza chithunzi chotsatirachi: 6 kudumpha ndi matalikidwe a 5,0 V pa kusintha kwa shaft kumbuyo kwa chizindikiro chochokera ku ziro. Mayesowa amatsimikizira kuti chizindikiro cha 120 chalembedwa molondola.

Poyatsira moto, gwirizanitsani voltmeter ku terminal ya waya yachikasu-wobiriwira. Yatsani choyatsira ndipo pang'onopang'ono muyambe kutembenuza shaft yogawa. Nthawi ino payenera kukhala kuphulika kwanthawi zonse kwa 5 volts ndi pafupipafupi ma PC 360 pakusintha kwa shaft. Njirayi imawonetsetsa kuti chizindikiro 1 chapangidwa molondola.

Pazotsatira zoyipa za macheke omwe afotokozedwa pamwambapa omwe amagawa zoyatsira (zida zamagetsi za injini akuwona Mutu) zimasinthidwa, - sensa ya CMR siyenera kutumikiridwa payekhapayekha.

Models kuyambira 1995 za.

Sensa ya CMP ili pachivundikiro cha nthawi kutsogolo kwa gawo lamagetsi. Sensa imakhala ndi maginito okhazikika, pachimake ndi waya wokhotakhota ndipo imagwiritsidwa ntchito kuti izindikire ma grooves mu camshaft sprocket. Pamene mano a sprocket akudutsa pafupi ndi sensa, maginito ozungulira amasintha, omwe amakhala chizindikiro chotulutsa magetsi kwa PCM. Kutengera kusanthula kwa chidziwitso kuchokera ku sensa, gawo lowongolera limatsimikizira malo a pistoni mu masilindala awo (TDC).

Chotsani mawaya a sensor. Pogwiritsa ntchito ohmmeter, yesani kukana pakati pa zikhomo ziwiri za cholumikizira cha sensor. Pa kutentha kwa 20 C, payenera kukhala kukana kwa 1440 ÷ 1760 Ohm (sensor yopangidwa ndi Hitachi) / 2090 ÷ 2550 Ohm (sensor yopangidwa ndi Mitsubishi), sensor yolakwika iyenera kusinthidwa.

Ngati zotsatira za mayeso omwe ali pamwambawa ndi abwino, onani zithunzi zolumikizira magetsi (onani zida zamagetsi za Head On-board) ndipo yang'anani mawaya amagetsi akuchokera ku PCM kuti muwone ngati akutha. Yang'anani zizindikiro za nthaka yoipa pa waya wakuda wa waya wa waya (gwiritsani ntchito ohmmeter). Ngati sensa ndi mawaya zili bwino, tengerani galimotoyo ku malo ogulitsa PCM ngati kuli kofunikira.

Camshaft udindo kachipangizo

Ndili ndi zaka ziwiri za BMW E39 M52TU 1998. Chilichonse chitha kukhala bwino, koma ndatopa kale ndikuphwanya sensa ya camshaft. M'zaka ziwirizi, tsopano ndikugula sensa yachisanu ndi chimodzi. Ndimagula sensa, ndimayendetsa kwa miyezi 1-2, imalephera, ndi hedgehogs ina 1-2 yokhala ndi yosweka. Ndinagula zonse zoyambirira, monga gehena, ndi bu yoyambirira, ndipo makampani ena amawononga imodzi, miyezi iwiri ndipo mukhoza kupita kwatsopano. Pa intaneti amangolemba zowonongeka kapena momwe angayang'anire zomwe sizikuyenda, koma palibe amene amalemba chifukwa chake zimalephera. Ndani angathandize? Kukumba kuti? Ndi chifukwa cha Vans?

Inde, ndinayiwala kufotokoza kuti camshaft sensor

Yambani ndi mphamvu Kodi crankshaft kapena camshaft sensor ndi chiyani? Koyilo wamba induction. Ngati mukuwotcha, yang'anani chakudyacho. XM Ndili ndi Chinese wamba ndi 1 ndi 2. Zonse zimagwira ntchito.

Ndinapita kwa amagetsi, ndimaganiza kuti akhoza kubwera ndi chinachake. Mwinamwake mtundu wina wa damper kapena chinachake chonga icho. Iwo sanathandize, adanena kuti ayenera kuyang'ana jini, chikhalidwe cha maburashi. Ndipo ndi kunyada konyansa kwamtundu wanji komwe kumagwira ntchito, nthawi zambiri pambuyo pake ubongo umayamba kuphulika.

Kuwona jenereta ndikosavuta. Tengani ma voliyumu wamba (wa China) a LCD ndikuyiyika kuti ikhale yodziwikiratu kuti muwone ma voltage spikes. Mtengo wa mankhwalawa ndi pafupifupi ma ruble 100. Ayenera kukhala 14-14,2

Ndangowomba makoyilo awiri sabata yatha. Mumodzi - kukana, muzolumikizana zonse - zopanda malire, ndiko kuti, kusiyana. Chachiwiri, kokha mu zobiriwira ndi zofiirira panali kukana, koma nthawi 10 kuposa momwe ziyenera kukhalira, ndipo mu zofiira panalinso kusiyana. Ndi zina zotero kwa koyilo yomweyo. Ndikuganiza kale kuti mwina izi ndichifukwa choti ndimayendetsa chingwe m'thupi la jini. Mwina pali mphamvu ya maginito yomwe ikugwira ntchito pano. Ngakhale pali chingwe chachifupi ndipo n'zovuta kukonza mosiyana. Ndipo apa pali sensa yachisanu ndi chimodzi. Posachedwapa ndidzayitana zomwe zili zoyenera ndikuyesera kuyika waya wa koyilo yatsopano mwanjira ina pafupi ndi khomo, osati ku jini. Ndipo voteji imayesedwa mwachindunji pa jini kapena ikhoza kukhala pa Akum?

Inde, pali kusiyana mu sensa yokha. Sindikumvetsa bwino zomwe izi zidzandipatsa, ndipo ndilibe katswiri wamagetsi, kotero ndidzachita popanda mafunso, koma ndiuzeni komwe ndingapeze pinout ya chip ECU.

Pakati pa mwendo wa 1 ndi 2 pa "bambo" wa sensa ayenera kukhala pafupifupi 13 ohms, pakati pa 2 ndi 3 pafupifupi 3 ohms. (mu masensa ena amalemba manambala a miyendo, ena samalemba)

Ndiye mudzadziwa kuti sensor yokhayo siifupikitsidwa.

Ndimayezera pa sensa pazolumikizana kwambiri 5,7, sinthani polarity, 3,5 ikuwonetsedwa. Pakati pa woyamba ndi wapakati 10.6 ngati mutasintha polarity, ndiye infinity. Pakati pa pakati ndi otsiriza 3,9, ngati mutasintha polarity, ndiye infinity. Momwe mungamvetsetse komwe kukhudzana kuli?

Mwachiphamaso anayang'ana ziwembu pa e39, sanapeze kanthu. Sensa ikhoza kungokhala ulalo wofooka mdera lanu, koma sindikupeza komwe kapena momwe zimayendera.

Momwe mungayang'anire sensor ya camshaft bmw e39

Patsiku "lokongola", "samurai" wanga sanafune kuyamba koyamba, ngakhale adayamba popanda vuto pakuyesera kwachiwiri (uku kunali kale kukhudza pang'ono kwa chidwi changa)

Pambuyo paulendo waufupi (kuwotha moto), nthawi yomweyo ndinazindikira kuti galimotoyo idakhala yaulesi - imathamanga pang'onopang'ono, imachita bwino ndi gasi, imayendetsa mocheperapo pokhapokha 2500-3000 rpm, panali zolephera pakuthamanga, kumveka kwa injini kunakhala Pa nthawiyi, liwiro la XX linali lokhazikika komanso labwinobwino, panalibe zopindika panjira, panalibe zolakwika mu dongosolo.

Ndidalumikiza INPU ndipo wolakwa adawonekera mu injini ECU: cholakwika 65, sensa ya camshaft.

Ndinaganiza zosintha ndekha, ndinagula VDO sensor mu sitolo yodalirika, popeza choyambirira sichinapezeke, komanso wogulitsa yemweyo adanena kuti VDO inali yoyambirira, koma ndi logo ya BMW ndi bokosi.

Ndinaganiza zopanga m'malo monga muvidiyo ili pansipa, pomwe, mwa njira, mnyamatayo adagwiritsa ntchito sensa ya Meile.

Musanalowe m'malo mwa sensa, ndizomveka kulola injini kuziziritsa, apo ayi kukwera pansi pa hood ndikovuta komanso kupsinjika!

10. Lowetsani sensa mu "socket", gwirizanitsani "chip" cha sensa ndikumangitsa bawuti yokweza sensa.
11. Mafuta a O-ring pa Vanos solenoid ndi mafuta atsopano ndikuyika mosinthana.
12. Timalumikiza scanner ndikukhazikitsanso cholakwika cha sensor mu kukumbukira

Zowonjezera ndi zolemba:

• kwa ine ndekha, chovuta kwambiri (ndi chotalika) chinali kumasula ndikugwirizanitsa cholumikizira cha sensa yokha, ndinapulumutsidwa chifukwa chakuti ndili ndi manja ang'onoang'ono osati zala zazikulu, ndipo ngakhale ndinavutika!
  
  Ndi fyuluta itachotsedwa ingakhale yabwino kwambiri.
• sensa ya VDO yosakhala yapachiyambi siili yosiyana ndi sensa yapachiyambi ya BMW: onse awiri amati Siemens ndi nambala 5WK96011Z, adangowonjezera chizindikiro cha BMW ku choyambirira.
• mutatha kusintha sensa, kuthamanga ndi mphamvu zonse za injini zasintha kwambiri, ndikuyembekeza kuti izi zipitirirabe.

Momwe mungayang'anire sensor ya camshaft bmw e39 m52

Ngakhale ndinazindikira kuti vuto linali chiyani, ndinapeza anthu omwe ali ndi mavuto ofanana, izi ndi zawo.

Zizindikiro zinali motere: jekeseni squealing, kuzimiririka pansi, kugwedezeka pa ntchito, kuchuluka kwa 20% kumwa, kusakaniza kolemera (chitoliro, lambda ndi chothandizira sichinunkhiza).

CHENJERANI! Zizindikiro ndizofanana ndi injini za M50 2l zokhala ndi jakisoni wa Nokia ndi M52 mpaka 98 kupita mtsogolo, mwina pamitundu yamtsogolo, sindinganene ena.

Ndinagwirizanitsa INPA, ndikulozera ku DPRV, ndinayang'ana deta yake, zikuwoneka kuti sizikudandaula.

Ndinachotsa sensa, kufufuzidwa ndi ohmmeter pakati pa 1 ndi 2 okhudzana ayenera kukhala 12,2 Ohm - 12,6 Ohm, pakati pa 2 ndi 3

0,39 ohm - 0,41 ohm Ndinali ndi kusiyana pakati pa 1 ndi 2. Ndinachotsa chingwe cha waya, chinapezeka kuti mawaya anali atafa. Ndinayesa kuyeza molunjika pa sensa, chinthu chomwecho. Anathyoledwa, anayeza zolumikizanazo ndikuwonetsetsa kuti zakonzeka.

Zimasintha mosavuta. Kachiŵirinso ndinasintha pambuyo pa mphindi 15, ulendo woyamba ndinakumba kwa mphindi 40.

Mudzafunika: malo owala bwino, ma wrenches (32, 19, 10 otseguka), socket 10 inchi yokhala ndi wrench, screwdriver yopyapyala, ndi manja ogwira. Ndi bwino kuchita chirichonse pa injini ozizira, manja anu adzakhala otetezeka.
