Mfundo yofunika kugwirira ntchito

1.oxygen sensor ndi kusintha kwa magalimoto pamagalimoto. Ndi gawo loyezera lomwe limagwiritsa ntchito zinthu zotheka kuti muchepetse matumbo ochulukitsa, ndikuwerengera oxygen yolingana molingana ndi kuchuluka kwa mpweya ndikuwonetsetsa kuti ndi yothetsa matendawa. Sensor ya oxygn imagwiritsidwa ntchito kwambiri mu mtundu wa malasha a malasha osiyanasiyana, mafuta oyaka, kuphatikiza mpweya ndi ng'anjo ina. Ndi njira yabwino kwambiri yothetsera momwe zinthu ziliri, ndipo zili ndi mawonekedwe osavuta, kuyankha mwachangu, kusanthu mosavuta, kugwiritsa ntchito molondola komanso molondola. Kugwiritsa ntchito sensor iyi kuti muyeze ndi kuyang'anira zinthu zomwe sizingakhazikike ndikusintha kwa malonda, komanso kufupika mapangidwe opanga mapangidwe ake ndikusunga mphamvu.

2.Muyezo wogwira wa sensor sensor yomwe ili pamagalimoto ndizofanana ndi batiri lowuma, ndipo chilengedwe cha zirconia mu sensor chimachita ngati electrolyte. Mfundo yake yogwira ntchito ndiyo: Pansi pa zochitika zina, kusiyana komwe kumapangidwa pogwiritsa ntchito mpweya wozungulira wa oxygen pakati pa zirconia, komanso kusiyana kwakukulu komwe kumayambitsa thupi. Zomwe zili mu mpweya mumlengalenga ndi 21%, ndi mpweya wopopera pambuyo osakaniza osakaniza mulibe mpweya. Gasi yotulutsa pambuyo pa join osakaniza kuphatikiza kapena mpweya wotuluka chifukwa chosowa moto amakhala ndi mpweya wabwino kwambiri, koma ndizocheperako kuposa mpweya m'mlengalenga. Pansi pa catalysis ya platinamum pamtunda wokwera kwambiri, wosungunuka mosavuta ma iongen a maysorbed mumtunda wamkati ndi kunja kwa zirsania. Chifukwa pali mpweya wabwino kwambiri pamlengalenga kuposa mpweya wopopera, mbali yolumikizirana ndi mlengalenga imataya masitima osokoneza bongo, ndipo kusiyana pakati pa masitima mbali zonse ziwiri mbali zonse ziwiri mbali zonse ziwiri kumapanga mphamvu zamagetsi.

3.Kodi oxygen ndende yotulutsa mafuta am'madzi ndi otsika, magetsi apamwamba (0,5 ~ 1V) amatumizidwa ku exygn exoric eyara kuti iwonjezere. Ecu imatenga chizindikiro champhamvu champhamvu ngati mphamvu yopanda tanthauzo komanso siginecha yotsika ngati siginecha yopanda chosakaniza. Malinga ndi chizindikiro cha nyuzipepala ya sensor, makompyuta amachepetsa kusakaniza malinga ndi kuchuluka kwa mafuta okwanira 14.7: 1. Kokha pomwe sensor ya oxygen ili kutentha kwambiri (kumapeto kwake kumafika kuposa 300 ° C) Makhalidwe ake amatha kuwonetsedwa ndipo voliyumu imatha kubweretsa. Pafupifupi 800 ° C, ili ndi yankho mwachangu ku kusintha kwa chisakanizo, koma mawonekedwe awa amasintha makamaka pa kutentha kochepa.
