1. Carbon deposition

Nekuda kwekupisa kwakashata kweinjini, kabhoni deposits inoumbwa pamusoro peiyo okisijeni sensor, kana madhipoziti akadai semafuta emafuta kana guruva anopinda muokisijeni sensor, iyo inotadzisa kana kuvharira kunze kwemhepo kupinda muokisijeni sensor, zvichiita inobuda chiratidzo cheiyo okisijeni sensor isina kurongeka, uye ECU haigone kugadzirisa chiyero chemhepo-mafuta munguva.Carbon deposition inonyanya kuratidzwa mukuwedzera kwekushandiswa kwemafuta uye kuwedzera kuri pachena kweiyo emission concentration.Panguva ino, kana sediment ikabviswa, inotangazve basa rakajairika.

2. Ceramic kupatsanurwa kweokisijeni sensor

Iyo ceramic yeokisijeni sensor yakaoma uye ine brittle, uye inogona kutyora nekutadza kana ikagogodzwa nechinhu chakaoma kana kushambidzwa nemhepo yakasimba.Saka, kunyatsotarisirwa kunofanira kutorwa pakubata, uye matambudziko anofanira kutsiviwa nenguva.

3. Iyo heater resistance wire inotsva

Kune iyo inopisa oksijeni sensor, kana iyo heater resistance wire yakabviswa, zvakaoma kuita kuti sensor isvike kune yakajairika tembiricha yekushanda uye kurasikirwa nebasa rayo.

4. Dunhu remukati reokisijeni sensor rakaputsika.

5.Kuongorora kwemavara ekuonekwa kweokisijeni sensor

Bvisa iyo okisijeni sensor kubva papombi yekuburitsa, uye tarisa kana gomba remhepo riri pa sensor imba rakavharwa uye iyo ceramic musimboti wakuvadzwa.Kana ikakuvadzwa, tsiva iyo okisijeni sensor.

Iko kukanganisa kunogonawo kutongwa nekucherechedza ruvara rwepipi yeokisijeni sensor:

① Chiedza chegrey tipi: Iyi ndiyo yakajairika ruvara rweokisijeni sensor;

② White tip: Inokonzerwa nekusvibiswa kwesilicon, uye sensor oxygen inofanira kuchinjwa panguva ino;

③ Brown tip: Inokonzerwa nekusvibiswa kwemutobvu.Kana yakakomba, iyo okisijeni sensor inofanirawo kutsiviwa;

④ Black tip: Inokonzerwa nekabhoni deposit.Mushure mekunge injini kabhoni dhipoziti kukanganisa yabviswa, iyo kabhoni dhipoziti paokisijeni sensor inogona kubviswa otomatiki.

Iyo huru okisijeni sensor inosanganisira kupisa tsvimbo yekudziya iyo zirconia element.Iyo yekudziya tsvimbo inodzorwa nekombuta (ECU).Kana mhepo inopinda iduku (kupisa kwekushisa kwakaderera), ikozvino inoyerera kusvika kune tsvimbo yekupisa kuti inopisa sensor, kuitira kuti kukanganiswa kweokisijeni kunogona kunyatsoonekwa.

Platinum electrodes inorongwa mukati uye kunze kwemativi e-tube-shaped zirconium element (ZRO2 _ 2).Kuti uchengetedze ma electrode eplatinamu, rutivi rwekunze rwemotokari rwakafukidzwa nekeramics, uye kuwedzera kweokisijeni mukati memukati kwakakwirira kudarika mhepo, asi iyo oksijeni yekunze kune imwe kunze yakaderera kudarika motokari inopedza gasi.
