Hazvina mhosva kuti mota yerudzii, ma sensor avo eokisijeni ane zvakajairika kutadza, isu tinokupa inoenderana mhinduro pamwe nemazano anoshanda ekuti iwe utonge kutadza.
Oxygen sensor poisoning
Bvisa mhepo inonzwa unit inouya kubva papombi yepombi, uyezve tarisa kuti gomba remhepo rinopinda paimba yekunzwa unit rakavharika here kana kuti ceramic primary yakuvadzwa.Kana ikanyatso paradzwa, iyo sensor yemhepo inofanirwa kutsiviwa.Kana ichingori chepfu chidiki chepamusoro, saka kushandisa bhokisi regesi isina kuburitswa inogona kubata nechirauro iyo nzvimbo yepamusoro yemhepo sensor uye kuidzosera kune yakajairwa maitiro.Asi kazhinji nekuda kwe tembiricha yakakwira yekupedza simba, lead inorwisa zvikamu zvayo zvemukati, izvo zvinodzivirira kutenderera kweokisijeni ion, uye zvakare inoburitsa iyo okisijeni sensor isingabereki.Parizvino, inogona kungotsiviwa.
Uye zvakare, silicon chepfu yeokisijeni inonzwa zvikamu inonyanya kufarirwa.Kazhinji kutaurirana, iyo silicon dioxide yakagadzirwa nekuda kwekubatidzwa kwesilicon zvinhu zvinosanganisirwa muhuni pamwe nemafuta ekuzora pamwe neiyo organic silicon mafuta anoburitswa kubva mukushandisa zvisina kunaka epurasitiki erabha gaskets zvinozokonzeresa iyo mhepo inonzwa unit kuregeredza.Naizvozvo, zvinotodiwa kushandisa mafuta emhando yepamusoro uye mafuta ekuzora.Paunenge uchigadzirisa, sarudza pamwe nekuisa gaskets erubha zvakanaka, pamwe nekuita kwete kutonga zvinonyungudutsa uye anti-sticking agents kunze kweiyo inotsanangurwa nemuiti pane yekunzwa unit.
Carbon deposition
Nekuda kwekupisa kwakashata kwemota, kabhoni dhaidhirodhi pasi mubhadharo wakavakirwa pamusoro pemhepo sensor, kana kunyange madhipoziti anosanganisira oiri kana tsvina mukati memhepo sensor inodzivirira kana kuvharira kunze kwedenga kuti ipinde muchikamu chinonzwa okisijeni. , kugadzira chiratidzo chinobuda nemhepo inonzwa unit zvisina kujeka uye zvakare ECU haigone kuve yakanyatso-nguva Kururamisa reshiyo yemafuta emhepo nemazvo.Kusimbiswa kweCarbon dioxide kunonyanya kuratidzwa mukuwedzera kwekushandiswa kwemafuta uye zvakare kuwedzera kunoshamisa kwekutarisa kwekuburitsa.Panguva ino, kana marara akabviswa, maitiro chaiwo anodzokera kune.
Air sensing unit ceramic yakakuvadzwa
Iyo ceramic yemhepo sensor yakanyanya kuoma uye zvakare yakatetepa, uye zvakare kupepeta chinhu chakaomarara kana kufefetera pamwe chete nemhepo ine simba yazvino kunogona kuita kuti iparare uye zvakare inopedzisira yava yenhema.Nekuda kweizvozvo, nyatso chenjera paunenge uchibata, uye uchinje nenguva kana paine dambudziko.
Iyo yekudziya unit yekudzivirira tambo inoyerera
Kune imba yekudziya yemhando yeokisijeni inonzwa unit, kana iyo yekudziya system yekupikisa tambo yakadzimwa, zvakanyanya kuoma kuunza iyo sensor kusangana neyakajairwa kushanda tembiricha uye zvakare kurasikirwa nekuita kwayo.
Kutenderera kwemukati kwemhepo inonzwa unit inoparadzaniswa
Kuongororwa kwekuonekwa uye mumvuri wemhepo inonzwa unit
Bvisa iyo sensor yemhepo kubva papombi yekuburitsa, uye zvakare tarisa kuti mhepo inovhurika paimba yekunzwa unit yakavharwa here kana kuti ceramic primary yaparara.Kana ikakuvadzwa, iyo air sensing unit inofanirwa kutsiviwa.
Mazano
Iko kukanganisa kunogonawo kutongwa nekucherechedza ruvara rwechikamu chepamusoro cheokisijeni sensor:
①Chiedza chegrey pamusoro: iyi ndiyo yakajairika ruvara rweokisijeni sensor;
②White tip: inokonzerwa nesilicon kusvibiswa, iyo okisijeni sensor inofanira kutsiviwa panguva ino;
③Brown tip: inokonzerwa nekusvibiswa kwemutobvu, kana yakakomba, iyo okisijeni sensor inofanira kutsiviwa;
④Black zano:inokonzerwa nekabhoni deposits.Mushure meiyo injini kabhoni dhipoziti kukanganisa kwabviswa, iyo kabhoni inoisa pane okisijeni sensor inogona kazhinji kubviswa otomatiki.
Iyo huru oksijeni sensor inosanganisira tsvimbo inopisa inopisa zirconia element.Iyo yekudziya tsvimbo inodzorwa ne (ECU) komputa.Kana iyo mhepo inotora idiki (yakaderera tembiricha yekupisa), ikozvino inoyerera ichienda kune inopisa tsvimbo yekupisa sensor kuti igone kugonesa kuona kweiyo oxygen concentration.
Ma electrode ePlatinum akaiswa kumativi ose emukati uye kunze kwezirconium element (ZRO2) mu test tube state.Kuti udzivirire electrode yeplatinum, rutivi rwekunze rwemotokari rwakafukidzwa nekeramics.Iko mukati meokisijeni yemukati yakakwira kupfuura mhepo, uye kunze kweokisijeni yakaderera pane iyo mota inopedza gasi.
Izvo zvinofanirwa kutaurwa kuti mushure mekutora iyo nzira nhatu-inoshandura inoshandura, unleaded peturu inofanira kushandiswa, kana zvisina kudaro iyo nzira nhatu inoshandura inoshandura uye okisijeni sensor ichakurumidza kutadza.Ziva zvakare kuti iyo okisijeni sensor inoita basa rakakosha mukudzikamisa iyo throttle uye kugadzirira yakajairwa kusanganisa.Kana kazhinji kupfumisa kana kuonda kusanganisa, iyo (ECU) komputa inofuratira iyo oksijeni sensor ruzivo, uye iyo okisijeni sensor haishande.

Maintenance uye kutsiva
Kugeza throttle chinhu chekuchengetedza icho munhu wese anoziva.Muchokwadi, zvinonyanya kukosha kuchenesa iyo okisijeni sensor.Mushure mezvose, iyo okisijeni sensor inoshanda munzvimbo yakaoma uye inonyanya kukuvara.Tisingatauri kuti inodzora huwandu hwemafuta anobaiwa.Iyo okisijeni sensor inogona kucheneswa nekunyorovesa nzira nhatu-catalyst cleaner kwemaminetsi gumi, uye wozoiomesa neinoomesa bvudzi.
Kana iyo okisijeni sensor yatadza, ndapota itsiva nekukasika.Kune VW ine mileage ye100,000 makiromita, inokurudzirwa kutsiva iyo okisijeni sensor.Isu tiri nyanzvi yeVW Oxygen Sensor inogadzira, kana iwe uchiida, tapota taura nesu nekukurumidza kuti uwane quote yemahara.
