Oxygen sensor Opel Astra

Mune yemagetsi enjini manejimendi (ECM) system, iyo lambda probe ine basa rekutarisa huwandu hweokisijeni mumagasi ekupedza. Iyo data sensor inogamuchirwa neECU inoshandiswa kugadzirisa mafuta musanganiswa wekupa kumakamuri ekupisa emasilinda.

Iyo inopfumisa kana yakaonda zviratidzo zvinokutendera iwe kuti uise iyo yakakwana zvikamu zvemafuta uye okisijeni yekupisa kuzere uye kushanda kwakanaka kweyuniti. MuOpel Astra exhaust system, iyo okisijeni sensor inowanikwa zvakananga pane inoshandura inoshandura.

Chishandiso uye musimboti wekushanda kwelambda probe

Iyo lambda probe yemazuva ano Opel Astra yechizvarwa chazvino ndeyemhando yebroadband ine galvanic cell yakavakirwa pazirconium dioxide. Dhizaini ye lambda probe inosanganisira:

• Muviri.
• Electrode yekutanga yekunze inosangana nemagasi ekupedza.
• Elekitirodhi yemukati inobatana nemhepo.
• Solid type galvanic cell (zirconium dioxide) iri pakati pema electrode maviri mukati mebhokisi.
• Kupisa tambo kugadzira tembiricha yekushanda (inenge 320 ° C).
• Spike pane casing kuti utore magasi anopedza simba.

Kutenderera kwekushanda kwe lambda probe kunobva pamusiyano ungangoita pakati pema electrode, ayo akaputirwa neakakosha-sensitive layer (platinum). Electrolyte inopisa panguva yekufamba kwemusanganiswa wemhepo yemuchadenga ine maion eokisijeni uye magasi emhepo, izvo zvinoita kuti mavoltages ane hunyanzvi hwakasiyana aoneke pama electrode. Iyo yakakwirira iyo oxygen concentration, iyo yakaderera voltage. Iyo amplitude yemagetsi impulse inopinda muECU kuburikidza neiyo control unit, uko chirongwa chinofungidzira dhigirii rekuzara kweiyo exhaust system neokisijeni zvichienderana nemagetsi emagetsi.

Diagnostics uye kutsiva okisijeni sensor

Kukundikana kwe "oxygen" kunotungamirira kumatambudziko nejini:

• Inowedzera kuwanda kwezvinokuvadza zvinobuda mumagasi emhepo
• RPMs inodonha kuita isina basa
• Kune kuwedzera kwekushandiswa kwemafuta
• Kuderera kwekufambisa kwemotokari

Hupenyu hwesevhisi ye lambda probe pane Opel Astra avhareji 60-80 zviuru zvemakiromita. Kuongorora dambudziko neokisijeni sensor kwakaoma - chishandiso hachikundike nekukurumidza, asi zvishoma nezvishoma, ichipa iyo ECU isina kururama maitiro uye kukundikana. Zvikonzero zvekupfeka nguva isati yakwana zvinogona kunge zvakaderera-mhando yemafuta, kushanda kweinjini nezvinhu zvakapfekwa zveboka re-cylinder-piston, kana kusagadziriswa kwevharuvhu.

Kutadza kweokisijeni sensor kunorekodhwa muODB memory log, makodhi ezvikanganiso anogadzirwa, uye "Check Injini" mwenje pane chiridzwa chinovhenekera. Decryption yemakodhi ezvikanganiso:

• P0133 - Voltage kuverenga kwakakwira zvakanyanya kana kuderera.
• P1133 - Kunonoka kupindura kana kutadza sensor.

Sensor malfunctions inogona kukonzerwa nemaseketi mapfupi, waya dzakatyoka, oxidation yeanobata materminal, kutadza kwevacuum (kudonha kwemhepo mumitsara yekutora) uye kusashanda majekiseni.

Iwe unogona kuzvimiririra kutarisa kushanda kwe sensor uchishandisa oscilloscope uye voltmeter. Kuti utarise, kuyera voltage pakati pe pulse waya (+) - paOpel Astra h waya nhema uye pasi - waya chena. Kana pachiratidziro che oscilloscope chiratidzo che amplitude pasekondi inosiyana kubva 0,1 kusvika 0,9 V, ipapo lambda probe iri kushanda.

Izvo zvinofanirwa kuyeukwa kuti iyo okisijeni sensor inotariswa neinjini ichidziya kusvika pakushanda tembiricha isina basa.

Maitiro ekutsiva

Kutsiva iyo okisijeni sensor neOpel Astra h, kiyi kunze kwe 22. Pamberi pebasa, zvinodikanwa kubvisa "negative" terminal yebhatiri uye kubvumira zvinhu zveiyo exhaust system kuti itonhorere.

• Dzvanya chibatiso chevhavha yewaya kune materminal e lambda probe.

• Bvisa tambo dzewaya kubva muinjini.

• Bvisa catalytic converter heat shield cover pane manifold.

• Bvisa nati kuchengetedza lambda probe nekiyi ku "22".

• Sunungura iyo okisijeni sensor kubva pane akawanda gomo.

• A new lambda probe inoiswa mune reverse order.

Pakutsiva, basa rose rinofanira kuitwa pane injini yakanyoroveswa pane tembiricha isingapfuuri 40-50 ° C. Iyo yakarukwa yekubatanidza ye sensor nyowani inobatwa neyakakosha thermal sealant iyo inogona kumira kutonhora kwakanyanya kudzivirira "kunamatira" uye kudzivirira hunyoro kupinda. O-mhete zvakare inotsiviwa nemitsva (kazhinji inosanganisirwa mukiti nyowani).

Iyo wiring inofanirwa kuongororwa kuti inokanganisa kukanganisa, kuputsika uye oxidation pane zviteshi zvekusangana, izvo, kana zvichidiwa, zvinocheneswa nekanyoro-grained sandpaper. Mushure mekuiswa, kushanda kwelambda probe kunoonekwa mune dzakasiyana injini dzekushandisa modes: 5-10 maminetsi pakuderera kusina basa, uye kuwedzera kwekumhanya kusvika pakukwira kwemaminetsi 1-2.
