Subaru Forester inogogodza sensor

Mapistoni ari muinjini yekupisa yemukati anofamba nekuda kwekupisa kwemafuta musanganiswa musanganiswa. Iyo nzira ine detonation hunhu, saka, kunyangwe kuderera kushoma musimba rayo, frequency, kuwedzera kwakakosha kwemaparamita ekupfeka kwemota. simba system. Detonation detonation (DD) inogara iri chikamu chemotokari, kusimudzira kupfeka kuSubaru neSoviet Forester.

Chii chinonzi kugogodza sensor: mabasa uye basa

Iwo mapatya pistons anofambisa kuburitsa kubva mumoto unopenya, iyo ine simba repamusoro rine yakakwira frequency muchikamu chekushanda. Muganho wesimba rakawandisa, masimba akadaro e detonation cycles, paanova anoparadza kune system, akatetepa. Kutyorwa kwayo hazvireve hazvo kuti kuparara kwakaitika munguva pfupi, asi kupfeka kwemota uye kuvakwa kwezvivakwa nazvo kuchawedzera kukurumidza.

Kusabatanidzwa kwezvisina-optimal zviratidzo zvekupisa kwechinhu chinopisa mumusanganiswa nekutsauka kubva pane zvakajairwa nekugadzirisa - iri pachena control unit (ECU). Kurongeka hakuzoitwe kana sisitimu "isingazive" nezve detonation - ndeyekutarisa kuitika kwayo iyo inogogodza sensor (DD, knock sensor) inoshanda. Saizvozvo, iko kurongeka kwekushanda kwayo kunoenderana nekurongeka kwezvigadziro muhurongwa hwese hwakatsanangurwa, kunaka kwesimba remagetsi, zviwanikwa uye node dzayo.

DD inoratidzika sei?

Iyo Subaru Forester inogogodza sensor, senge mhando zhinji dzemhando iyi, ndeye yakatenderera torus. Padivi, ine terminal yekubatanidza kune yemagetsi control unit yeinjini yekupisa yemukati. Pakati pane buri rekuiswa. A piezoelectric element inoiswa mu intrafunctional segment ye sensor, iyo inobata kune vibration nekugadzira diki voltage uye yakapihwa frequency.

Iyo komputa inogara ichiongorora mapurusi anobva kuma sensors - Kana paine kutsauka kubva pazviyero zvakajairwa, ongororo yekutaridzika kwe detonation Uyezve, iyo control module, zvinoenderana nechirongwa chakarongwa, inova nechokwadi chekugadziriswa kweinjini yekupisa yemukati, Kubvisa zvisiri izvo. -kupisa kwakanyanya kweFuel Mixture.

Iko kugogodza sensor iri kupi?

Nzvimbo yeDD inotarirwa nevagadziri kuitira kuti kunzwisisika kunobudirira kunowanikwa, izvo zvinowedzera kururamisa kwekuonekwa kwe detonation kunyange pamatanho ekutanga ekuongorora.

Nzvimbo yekugogodza sensor iri pakati pemhepo sefa bhokisi uye manifold ekutora, pasi pevhavhavhavha, iyo nzvimbo iyo iri pachikamu nemasilinda.

Maitiro ekutarisa iyo yekugogodza sensor

Kukuvadza kugogodza sensor Chokutanga pane zvose, kukanganisa matanda (makodhi) anoratidzwa pakuonekwa kweecu nekombuta yepa-board. Cheki Injini inoratidzwa pane pane. Iyi yekuzviongorora inongowanikwa mune yemazuva ano Subaru modhi uye inokwanisa kugadzirisa kunzwisiswa kwe sensor, kuwedzera kuburitsa voltage, uye dunhu rakavhurika. Mhando yega yega yekusashanda ine kodhi yayo, iyo decryption iri muhunyanzvi zvinyorwa pamushini, ruzivo rwunowanikwa paInternet.

Multimeter

Iwe unogona kuongorora hutano hweDD ne multimeter kana voltmeter. Order:

• Kubvisa sensor: bhaudhi rekugadzirisa harina kuvharwa, gungano rinobvaruka nyore. Nzvimbo, chitarisiko chatakashandisa pamusoro, sensor haigone kuwanikwa.
• Tester probes dzakabatana kune zvakabuda. Multimeter shanduko kuDC yazvino kuyerwa, huwandu hunosvika 200mV (kana pasi).
• Nekuedza kunonzwisisika, iwe unofanirwa kutanga, unogona kudzvanya, shandisa dd chikamu nebhaudhi, tsvimbo yesimbi, screwdriver. Nenguva yekushandiswa, nguva ichauya uye kuberekwa kweimba kuchaitika kubva May 20 kusvika May 30.
• Tarisa zvishandiso. Mumamiriro akanaka, kukanganisa kunoperekedzwa nekumhanya kwesimba nguva yega yega. Kushaya mhinduro zvinoreva kukundikana.

Yechipiri yekuongorora nzira yakafanana neyakatsanangurwa, Chete bvunzo shanduro muyero yekupimisa (maka pane yakasarudzwa kusvika 1000 ohms kana 1 kΩ). Mumamiriro ezvinhu akajairika achava anenge 400-600. Panguva yekugogodza, kukosha pabhodhi rezvibodzwa kuchakura zvakangoita (kazhinji 1-2 com) uye kudzokera kumusanganiswa wepakutanga.

Zvinorayirwa:

• muzviitiko zvese zvakakosha kutarisa kuti saizi iri pachiratidziro inodzokera kumashure. Kana izvi zvikaitika nekupindwa muropa, ipapo sensor inogona kunge yakaputsika;
• iwe unofanirwa kuve nechokwadi chekuti maprobes akabatana zvakachengeteka - vanobatika pane sensor vanogona kunge vane tsvina, p;
• shanduko yemagetsi pane sensor inogona kuve akati wandei mamilivolts, kwete yese bvunzo inogona kuiratidza. Uye kana kuyera kushorwa mukati meOhms, saka, cheki yakadaro ndiyo yekutanga;
• pane imwe nguva yakakodzera, kana ukayera voltage, iyo multimeter inofanira kuva nehutano hunodiwa.

Kutarisa dunhu kune bhuroka rekombuta

Hunhu hwezvinotevera. Iyo sensor haibvise. Bvisa plug yeECU, tanga wabvisa "-" pabhatiri. Edza ukuru hwemapurusi akaiswa. Chinetso ndechekuti iwe unofanirwa kuziva iyo pinout yeplug, izvo zvigadziko zvepadhi zvinodzima sensor. Kuti ujairane nemichato ine hunhu nemaoko kana kunyange nyore - kuwana ruzivo kubva kune

Inotsanangurwa inogona kuzivikanwa mukana wekutenderera kwemagetsi kune iyo control unit, kukosha kweiyo inoshandiswa sensory impulse inoyerwa. Order:

1. Bvisa bhuroka kubva kumota control unit.
2. 2 maitirwo anowanikwa pane block, tester probes akabatana navo, kana akasatendeuka, unogona kutengesa waya kwavari.
3. The tester selector inoshandura kune voltage mark ye200 mV.
4. Vanogogodza pane sensor kana kusaiteerera pamberi. Nhamba dziri pabhodhi rezvibodzwa dzinofanira kushanduka mukusvetuka uye miganhu.

Izvo zvinokurudzirwawo kuongorora shielding braid kubva kuECU kuenda kuDD: nekuda kwekukuvara kwayo, harmonics inogona kuoneka inokanganisa kushanda kweiyo unit uye kuisirwa kwakaringana kwechisarudzo ECU.

Tarisa pasina kubvisa

Zvinogoneka kuongorora iyo Subaru inogogodza sensor, uye haisi kuoneka kubva mumotokari:

1. Chinja injini kuti isashande.
2. Tinya pane chikamu chekushanda che sensor.
3. Kana iyo crankshaft yekumhanyisa iri chokwadi, chokwadi chekuti kana izvi zvikasaitika, saka kuparara hakusati kuchiitika.

Matambudziko pakuongorora

Iko kusakosha kwemaitiro akazvimirira ekutarisa DD ndeyekuti ese haatenderi kunyatso, zvachose 100% kunyangwe kana padhuze sezvinobvira kuona mamiriro eiyo sensor. Chikonzero chiri mune zvemhando yekushanda: kune yakajairika mashandiro mudziyo, pulses of frequency frequency, periodicity of oscillations inofanirwa kugadzirwa, uye izvi zvinoenderana nehuwandu hwekudedera, izvo zvisiri nyore kugadzira mune ese frequency shanduko.

Zvizhinji zvezviri pamusoro, kuongororwa kwakazara neakagadziridzwa nzira hazvigoneke - chete cheki pachigadziko chakakosha kana chigadziriso chekuongorora chinopa mhedzisiro chaiyo.

Nzira dzese dzakazvimiririra dzine maturusi akavandudzwa, multimeter, zvichienderana nekukwanisa kudiki kwe sensor, asi mune zvimwe zviitiko zvakakosha, kusvetuka pachako hakuratidzirwe, asi maitiro avo ekuwedzera, ayo anotemerwa chete nemuongorori chaiwo.

Replacement

Nhanho yekugadzirira - zvishandiso: kusungirira mukuita kusunungura neyakavhurika-kuguma "10", socket wrench "12", ratchet ine kuwedzera, crank. Iwe uchada flathead screwdriver. Yekuchenesa - mamvemve, eshinda dzine ngura - mafuta anopinza.

Knock sensor kutsiva maitiro

Kubvisa yekare uye nekuisa nyowani yekugogodza sensor paSubaru Forester inosanganisira inotevera maitiro. Inodzikiswa netiweki, kubva ku "-" terminal yebhatiri. Vanobvisa iyo intercooler, iyo 2 fasteners isina kuvharwa, peya ye clamps yakasunungurwa.

Bvisa iyo "chip" (chibatanidza) cheiyo inogogodza sensor.

Bhaudhi rekusungirira harina kuvharwa, DD inoburitswa nayo.

Nhanho yekupedzisira ndeyekuiswa kweiyo nyowani yekugogodza sensor. Gungano racho rakaitwa zvakatevedzana.
