Kukho iintlobo ezimbini ze-oxygen sensors ezisetyenziswa ekusebenzeni: i-zirconia ye-oxygen sensor kunye ne-titania ye-oxygen sensor. Izinzwa ze-oksijini eziqhelekileyo zohlulwe zibe zikhokelo enye, i-lead ephindwe kabini kunye ne-lead ezintathu. I-lead eyodwa yi-zirconia oxygen sensor; Inzwa ye-oksijeni ye-titanium oxide ephindwe kabini; Inzwa ye-oksijini enezikhokelo ezintathu i-zirconia oxygen sensor evuthayo. Ngokomgaqo, inzwa ye-oxygen enezikhokelo ezintathu ayinakutshintshwa.

Nje ukuba i-sensor ye-oksijini isilele, ikhompyuter yenkqubo yokutofa kwe-elektroniki ayiyi kukwazi ukufumana ulwazi lokuxinana kwe-oksijini kumbhobho wokukhupha, ngoko ke umlinganiselo wepetroli womoya awukwazi ukulawulwa yingxelo, eya kwandisa ukusetyenziswa kwamafutha kunye nokuphuma. Ungcoliseko lwe-injini, kunye ne-injini iya kuba nesantya esingazinzanga sokungenzi nto, i-misfire kunye ne-surgery. Ke ngoko, ukulungisa ingxaki okanye ukutshintshwa kufuneka kwenziwe kwangexesha.

Iimpazamo eziqhelekileyo zenzwa ye-oxygen

Ityhefu yesivamvo seoksijini

Ityhefu ye-oxygen sensor yinto eqhelekileyo kwaye inzima ukuyithintela, ngakumbi kwiimoto ezihlala zisebenzisa i-petroli ekhokelayo. Nokuba inzwa entsha yeoksijini inokusebenza kuphela amawaka eekhilomitha. Ukuba kukho i-poisoning encinci ye-lead, kwaye ke ibhokisi ye-petroli engabonakaliyo isetyenzisiweyo, i-lead phezu kwe-sensor ye-oxygen inokupheliswa kwaye inokubuyiselwa emsebenzini oqhelekileyo. Nangona kunjalo, ngenxa yobushushu obuphezulu bokuphuma, ilothe idla ngokungena ngaphakathi kuyo, nto leyo ethintela ukusasazwa kwee-ion zeoksijini kwaye yenze inzwa yeoksijini ingasebenzi. Ngeli xesha, inokutshintshwa kuphela.

Ukongeza, kuqhelekile ukuba izinzwa zeoksijini zihlupheke ngenxa yetyhefu ye-silicon. Ngokubanzi, i-silicon dioxide eveliswa kukutsha kweekhompawundi ze-silicon eziqulethwe kwipetroli kunye ne-oyile yokuthambisa, kunye nerhasi yesilicone ekhutshwa kukusetyenziswa ngokungafanelekanga kwe-gasket yokutywina yerabha ye-silicone iya kwenza ukuba isivamvo se-oksijini singasebenzi, ngoko ke kuyimfuneko ukusebenzisa amafutha akumgangatho ophezulu. kunye neoli yokuthambisa. Xa kulungiswa, i-gasket ye-rubber kufuneka ikhethwe kwaye ifakwe ngokuchanekileyo, kwaye inzwa akufanele ifakwe i-solvents kunye ne-anti-sticing agents ngaphandle kwalawo achazwe ngumenzi.
