Pali mitundu iwiri ya masensa omwe amagwiritsidwa ntchito pochita izi: Zirconia oxygen sensor ndi sopor oxygen. Ma eyaki a oxgen wamba amagawidwa kukhala mbendera imodzi, kutsogolera kwawiri ndi kutsogolera atatu. Kutsogolera kamodzi ndi zirconia oxygen sensor; Kutsogolera kawiri oxide oxygen; Sensor ya oxygen yokhala ndi ziwonetsero zitatu ndi sensor yazithunzi yophika. M'malo mwake, sensor sensor yokhala ndi zowongolera zitatu sizingasinthidwe.

Sensor sensor imalephera, kompyuta yamagetsi yamagetsi sangathe kudziwa zambiri za oxygen ndende yothetsa, zomwe zimapangitsa kuti mafuta a injini azitha kuwongolera, ndipo injiniyo idzasunthika mwachangu. Chifukwa chake, kuswana kapena kusinthidwa kuyenera kuchitika munthawi yake.

Zolakwa Zofala za Sensor Sensor

Oxygen syrar poyizoni

Poizoni wa oxygen exyar ndi cholakwika wamba komanso chovuta kupewa, makamaka magalimoto omwe nthawi zambiri amagwiritsa ntchito mafuta otsogolera mafuta. Ngakhale sensor yatsopano ya oxygen imangogwira ntchito makilomita masauzande ambiri. Ngati pali poizoni pang'ono poizoni, kenako bokosi la mafuta osaletsedwa limagwiritsidwa ntchito, kutsogoleredwa pamwamba pa sensor ya oxygen ikhoza kuchotsedwa ndipo zitha kubwezeretsedwanso. Komabe, chifukwa cha kutentha kwambiri, kumabweretsa nthawi zambiri kumalowa mkati mwake, zomwe zimalepheretsa kusokonekera kwa mabotolo a oxygen ndikupangitsa sensor ya oxygen osagwira ntchito. Pakadali pano, imatha kusinthidwa.

Kuphatikiza apo, ndizofala kwa masensa a oxygen kuti avutike ndi sicrean poyizoni. Nthawi zambiri, siyicon dioxide omwe amapangidwa ndi kuphatikiza kwa mafuta a sicon ndi mafuta opangira mpweya, ndipo ndikofunikira kugwiritsa ntchito mafuta apamwamba kwambiri komanso mafuta odzola. Mukakonza, gasket ya mphira iyenera kusankhidwa ndikuyika molondola, ndipo sensor siyenera kuphatikizidwa ndi ma sol sols ndi anti-othandizira ena kupatula omwe amatchulidwa ndi omwe amapanga.
