Kune marudzi maviri eokisijeni sensors anoshandiswa mukuita: zirconia oxygen sensor uye titania oxygen sensor.Iwo akajairika maokisijeni sensors akakamurwa kuita imwechete lead, kaviri lead uye matatu lead.Iyo imwe chete inotungamira ndeye zirconia oksijeni sensor;Kaviri-lead titanium oxide oxygen sensor;Iyo okisijeni sensor ine matatu inotungamira inodziya zirconia oksijeni sensor.Muchidimbu, iyo okisijeni sensor ine matatu inotungamira haigone kutsiviwa.

Kamwe iyo okisijeni sensor yakundikana, komputa yemagetsi jekiseni remagetsi haizokwanise kuwana ruzivo rweokisijeni kusungwa mupombi yekupedza, saka chiyero chemhepo-mafuta haigone kudzorwa, izvo zvinowedzera kushandiswa kwemafuta uye kupera simba. kusvibiswa kweinjini, uye injini ichave isina kugadzikana isingaiti kumhanya, kukanganisa uye kuvhiya.Naizvozvo, kugadzirisa kana kutsiva kunofanirwa kuitwa nenguva.

Kukanganisa kwakajairika kweokisijeni sensor

Oxygen sensor poisoning

Oxygen sensor poisoning imhosva yakajairika uye yakaoma kudzivirira, kunyanya kumota dzinowanzoshandisa leaded peturu.Kunyangwe sensor itsva yeokisijeni inogona kungoshanda kwezviuru zvemakiromita.Kana paine chepfu shoma yekutungamirira, uye ipapo bhokisi remafuta asina kutungamirirwa rinoshandiswa, mutungamiri pamusoro peiyo okisijeni sensor inogona kubviswa uye inogona kudzorerwa kubasa rakajairika.Nekudaro, nekuda kwekushisa kwemhepo yakakwira, lead inowanzopinda mukati mayo, izvo zvinotadzisa kupararira kwemaion yeokisijeni uye inoita kuti sensor yeokisijeni isashande.Panguva ino, inogona kuchinjwa chete.

Uye zvakare, zvakajairika kuti maokisijeni sensors atambure nesilicon chepfu.Kazhinji kutaura, iyo silicon dioxide inogadzirwa nekupiswa kwesilicon diokisi iri mupeturu nemafuta ekuzora, uye gasi resilicone rinoburitswa nekushandiswa zvisina kunaka kwesilicone rubber sealing gasket rinoita kuti sensor yeokisijeni isashande, saka zvinodikanwa kushandisa mafuta emhando yepamusoro. nemafuta ekuzora.Paunenge uchigadzirisa, gasket yerubha inofanira kusarudzwa uye kuiswa zvakanaka, uye sensor haifaniri kuputirwa nemishonga uye anti-sticing agents kunze kweiyo inotsanangurwa nemuiti.
