Subaru Forester kugogoda sensor

Ma pistoni omwe ali mu injini yoyaka mkati amayenda chifukwa cha kuyaka kwa mafuta osakaniza mu osakaniza Njirayi imakhala ndi mawonekedwe a detonation, chifukwa chake, ngakhale kuchepa pang'ono kwa mphamvu yake, mafupipafupi, kuwonjezeka kwakukulu kwa magawo a galimoto, dongosolo mphamvu. Detonation detonation (DD) ndi gawo lokhazikika lagalimoto, kuvala ku Subaru ndi Soviet Forester.

Kodi kugogoda sensor ndi chiyani: ntchito ndi ntchito

Ma pistoni amapasa amasuntha mpweya wochokera kumoto wamoto, mphamvu yaikulu yomwe imakhala ndi maulendo apamwamba mu chipinda chogwirira ntchito. Malire a mphamvu zochulukirapo, mphamvu zotere za kuzungulira kwa detonation, zomwe zimakhala zowononga dongosolo, ndizochepa kwambiri. Kuphwanya kwake sikukutanthauza kuti kuwonongeka kunachitika posachedwa, koma kuvala kwa injini ndi kumanga nyumba ndi izo zidzafulumizitsa.

Kupatulapo zizindikiro zosawoneka bwino za kuyaka kosakanikirana kosakanikirana ndi kupatuka kwachizolowezi ndikusintha - gawo lodziwikiratu lowongolera (ECU). Kukonzekera sikungachitike ngati dongosolo "sikudziwa" za kuphulika - ndikuwunika momwe zimachitikira kuti sensa yogogoda (DD, kugogoda sensa) imagwira ntchito. Chifukwa chake, kulondola kwa magwiridwe antchito ake kumadalira kulondola kwa makonda mu dongosolo lonse lofotokozedwa, mtundu wagawo lamagetsi, zothandizira ndi mfundo zake.

Kodi DD imawoneka bwanji?

Subaru Forester knock sensor, monga mitundu yambiri yamtunduwu, ndi torus yozungulira. Kumbali, ili ndi cholumikizira cholumikizira kugawo lowongolera magetsi la injini yoyaka mkati. Pakatikati pali dzenje loyikapo. Chinthu cha piezoelectric chimayikidwa mu gawo la intrafunctional la sensa, yomwe imakhudzidwa ndi kugwedezeka popanga magetsi ang'onoang'ono ndi mafupipafupi operekedwa.

Kompyutayo nthawi zonse imasanthula ma pulse omwe amachokera ku masensa - Ngati pali kupatuka kuchokera ku miyeso yabwinobwino, kuwunika kwa mawonekedwe a detonation Komanso, gawo lowongolera, malinga ndi pulogalamu yokhazikitsidwa, limatsimikizira kuwongolera kwa injini yoyaka mkati, Kuchotsa -Kuyatsa koyenera kwa Mafuta Osakaniza.

Kodi sensor yogogoda ili kuti?

Malo a DD amatsimikiziridwa ndi okonza kuti apindule bwino, zomwe zimawonjezera kulondola kwa kuzindikira kwa detonation ngakhale pazigawo zoyamba za kusanthula.

Malo a sensa yogogoda ali pakati pa bokosi la fyuluta ya mpweya ndi manifold intake, pansi pa valve throttle, malo omwe ali pagawo limodzi ndi ma silinda.

Momwe mungayang'anire sensor yogogoda

Kuwonongeka kwa sensa yogogoda Choyamba, zolemba zolakwika (makhodi) zimawonetsedwa pakuzindikira kwa ecu ndi kompyuta yomwe ili pa bolodi. Check Engine akuwonetsedwa pa gulu. Dongosolo lodzizindikiritsa lokhali limapezeka mumitundu yamakono ya Subaru ndipo imatha kukonza kukhudzidwa kwa sensa, kukulitsa mphamvu yamagetsi, ndi dera lotseguka. Mtundu uliwonse wa kusagwira bwino ntchito uli ndi code yake, decoding ili muzolemba zamakina pamakina, zambiri zimapezeka pa intaneti.

Multimeter

Mutha kusanthula thanzi la DD ndi multimeter kapena voltmeter. Kuitanitsa:

• Kugwetsa sensa: bolt yokonza imachotsedwa, msonkhanowo umatha mosavuta. Malo, mawonekedwe omwe tidagwiritsa ntchito pamwambapa, sensa sichipezeka.
• Ma probe oyesa amalumikizidwa ndi zotuluka. Multimeter kutembenuka kukhala DC muyeso panopa, osiyanasiyana ndi pafupifupi 200mV (kapena zochepa).
• Ndi kuyesayesa koyenera, muyenera kuyamba, mutha kukanikiza, gwiritsani ntchito gawo la dd ndi bawuti, ndodo yachitsulo, screwdriver. Pofika nthawi yogwiritsidwa ntchito, nthawi idzafika ndipo kubadwa kwa nyumbayo kudzachitika kuyambira Meyi 20 mpaka Meyi 30.
• Penyani zida. M'malo abwino, zotsatira zake zimatsagana ndi kukwera kwamphamvu nthawi iliyonse. Kusayankha kumatanthauza kulephera.

Njira yachiwiri yotsimikizira ndi yofanana ndi yomwe yafotokozedwa, Kutanthauzira koyeserera kokha mumayendedwe oyesa kukana (chizindikiro pa chosankha mpaka 1000 ohms kapena 1 kΩ). Mu chikhalidwe chabwino adzakhala pafupifupi 400-600. Panthawi yogogoda, mtengo pa boardboard udzakula pafupifupi (nthawi zambiri 1-2 com) ndikubwereranso kuphatikizidwe koyambirira.

Malangizo:

• muzochitika zonse ndikofunikira kuyang'ana kuti kukula kwawonetsero kumabwereranso. Ngati izi zichitika ndi chizoloŵezi choledzeretsa, ndiye kuti sensayo imakhala yosweka;
• muyenera kuwonetsetsa kuti ma probe amalumikizidwa bwino - zolumikizira pa sensa zitha kukhala zodetsedwa, p;
• Kusintha kwamagetsi pa sensa kumatha kukhala ma millivolts angapo, osati mayeso aliwonse omwe angawonetse. Ndipo poyesa kukana mkati mwa Ohms, choncho, cheke chotere ndichofunika kwambiri;
• pa nthawi yoyenera, ngati muyeza magetsi, multimeter iyenera kukhala ndi khalidwe lofunika.

Kuyang'ana dera ku chipika cha kompyuta

Chofunika cha zotsatirazi. Sensa sichichotsa. Chotsani pulagi ya ECU, choyamba chotsani "-" pa batri. Yezerani kukula kwa ma pulses omwe agwiritsidwa ntchito. Chovuta ndichakuti muyenera kudziwa pinout ya pulagi, zomwe zitsulo za pad zimazimitsa sensa. Kudziwana ndi maukwati abwino pamanja kapena mosavuta - kupeza zambiri kuchokera kwa

Kufotokozedwa kungathe kudziwika kuti n'zotheka kuzungulira magetsi ku gawo lolamulira, mtengo wa mphamvu yogwiritsira ntchito mphamvu imayesedwa. Kuitanitsa:

1. Chotsani chipika pagawo lowongolera magalimoto.
2. Zolumikizana 2 zimapezeka pa block, zoyesa zoyeserera zimalumikizidwa kwa iwo, ngati siziyatsa, mutha kugulitsa mawaya kwa iwo.
3. Chosankha choyesa chimatanthawuza chizindikiro cha voteji cha 200 mV.
4. Amagogoda pa sensa kapena osamvera pamaso pake. Manambala omwe ali pa boardboard ayenera kusintha modumphadumpha komanso malire.

Komanso m'pofunika kuyendera kuluka kutchinga ku ECU kuti DD: chifukwa cha kuwonongeka, harmonics angaoneke kuti zimakhudza ntchito ya unit ndi unsembe olondola chigamulo ECU.

Onani popanda kuchotsedwa

Ndizotheka kusanthula sensa ya Subaru kugogoda, ndipo sizikuwoneka kuchokera mgalimoto:

1. Sinthani injini kuti ikhale yopanda ntchito.
2. Dinani pa gawo logwira ntchito la sensor.
3. Ngati liwiro la crankshaft ndi lolondola, kuti ngati izi sizichitika, ndiye kuti kuwonongeka sikuchitika.

Zovuta pakuzindikira

Kuipa kwa njira zodziyimira pawokha zowunikira DD ndikuti zonse sizimalola molondola, kwathunthu 100% ngakhale kapena kuyandikira momwe mungathere kuti mudziwe momwe sensor iliri. Chifukwa chake chiri mu mawonekedwe a magwiridwe antchito: pazida zogwirira ntchito wamba, ma pulses of frequency frequency, periodicity of oscillations ayenera kupangidwa, ndipo izi zimatengera kuchuluka kwa kugwedezeka, zomwe sizili zophweka kupanga pakusintha pafupipafupi.

Zambiri mwazomwe tafotokozazi, kuwunika kwathunthu ndi njira zotsogola sikutheka - cheke chokhacho pamayimidwe apadera kapena chida chowunikira chimapereka zotsatira zolondola.

Njira zonse zodziyimira pawokha zokhala ndi zida zotsogola, ma multimeter, kutengera kuthekera pang'ono kwa sensa, koma nthawi zina zofunika kudumpha sikumawonetsedwa, koma mawonekedwe awo owonjezera, omwe amatsimikiziridwa ndi oyesa enieni.

m'malo

Gawo lokonzekera - zida: kumangiriza pakumasula ndi "10" yotseguka, socket wrench "12", ratchet yokhala ndi chowonjezera, crank. Mudzafunika screwdriver flathead. Zoyeretsa - nsanza, za ulusi wa dzimbiri - mafuta olowera.

Njira yosinthira sensa ya knock

Kuchotsa zakale ndikuyika sensa yatsopano yogogoda pa Subaru Forester kumaphatikizapo njira zotsatirazi. Imachotsedwa mphamvu ndi netiweki, kuchokera ku "-" terminal ya batri. Iwo amachotsa intercooler, amene 2 zomangira ndi unscrew, awiri a clamps amamasulidwa.

Chotsani "chip" (cholumikizira) cha sensor yogogoda.

Bawuti yomangirira sinadulidwe, DD imatulutsidwa nayo.

Gawo lomaliza ndikukhazikitsa sensor yatsopano yogogoda. Msonkhanowu unachitika motsatira ndondomekoyi.
