Chii chiri pamberi pe sensor yeokisijeni yemotokari
Pamberi pesensa yeokisijeni yemotokari pane chinoshandura okisijeni chenzira nhatu. Chinoshandura okisijeni chenzira nhatu chiri mushure mesensa yeokisijeni, uye basa rayo guru nderekuderedza huwandu hwemhepo inosvibisa mugasi rinobuda mumhepo uye kuchengetedza nharaunda.
Basa nenzvimbo yemuchina wemagetsi une nzira nhatu (three-way catalytic converter)
Chinoshandura simba chemagetsi chine nzira nhatu chinoiswa mushure me sensor yeokisijeni uye chinowanzo kuwanikwa kumashure kwe exhaust system. Basa rayo guru nderekuderedza zvinhu zvinokuvadza mumagasi e exhaust, akadai se carbon monoxide, hydrocarbons uye nitrogen oxides, nokudaro zvichideredza kukanganiswa kwe exhaust emissions panharaunda.
Basa uye nzvimbo ye sensor yeokisijeni
Masensa eokisijeni akakamurwa kuita sensor yeokisijeni yekumberi uye sensor yeokisijeni yekumashure:
Sensor ye okisijeni yepamberi: yakaiswa pamberi pe catalyst ine nzira nhatu, kazhinji iri kumashure kwe exhaust manifold. Basa rayo guru nderekuona huwandu hwe okisijeni mu exhaust uye kudzorera chiratidzo kuECU kuti ibatsire kugadzirisa chiyero chemhepo-mafuta einjini kuti irambe iri pamutengo wakakodzera (14.7:1).
Sensor yeposterior oxygen : yakaiswa mushure me three-way catalytic converter. Basa rayo guru nderekuona kuumbwa kwegasi remuswe mushure mekurapa three-way catalytic converter, uye kudzorera chiratidzo kuECU kuti ibatsire kutarisa kana mashandiro e three-way catalytic converter ari akajairwa .
Mazano ekugadzirisa nekutsiva
Zvese zvinonzwa okisijeni nema catalytic converters zvinoda kuongororwa nekugadziriswa nguva nenguva. Kushandiswa kwenguva refu kwema okisijeni kunogona kukonzera chepfu ye lead kana kuunganidzwa kwekabhoni, zvichikonzera kudzikira kwekushanda. Kana ukaona kuwedzera kwekushandiswa kwemafuta, simba shoma nezvimwe zviitiko, zvinogona kunge zviri chiratidzo chekukuvadzwa kwe okisijeni sensor .
Zvinokurudzirwa kutarisa sensor yeokisijeni makiromita ese 100,000 kana kupfuura uye woitsiva kana zvichidikanwa kuti mota irambe ichishanda zvakanaka uye kuderedza kusvibiswa kwemhepo inobuda.
Basa guru re automobile front oxygen sensor nderekutarisa huwandu hweokisijeni mu exhaust gas mushure mekupiswa kweinjini, uye kuishandura kuita chiratidzo chemagetsi chinotumirwa ku engine control unit (ECU), kuitira kuti iwane closed-loop control uye kugadzirisa musanganiswa we mixture ratio, kuitira kuti ivandudze kushanda zvakanaka kwe engine combustion uye hunhu hwe exhaust emission.
Zvikuru, sensor ye okisijeni yekumberi yakaiswa pa exhaust manifold uye mabasa ayo makuru anosanganisira:
Kutarisa huwandu hweokisijeni: Sensor ye okisijeni yekumberi inoona huwandu hweokisijeni mugasi re exhaust nekuona kana paine okisijeni yakawandisa mugasi re exhaust mushure mekupiswa kweinjini. Okisijeni yakawanda zvinoreva kuti musanganiswa wacho mutete, nepo huwandu hweokisijeni shoma zvichireva kuti musanganiswa wacho wakasimba zvakanyanya.
Mutemo wemhinduro: zvichienderana nehuwandu hwakasiyana hweokisijeni, sensor ye okisijeni yepamberi inotumira chiratidzo chemagetsi chinoenderana kuECU, kuitira kuti ECU igone kugadzirisa injection yemafuta zvichienderana nemhepo yakawandisa, iwane kudzora kwe closed-loop, uye ive nechokwadi chekuti injini inogara iri mumamiriro akanaka ekushanda.
Kuvandudza kushanda zvakanaka kwekupisa: Nekudzora chiyero chemusanganiswa, sensor ye pre-oxygen inogona kuve nechokwadi chekuti chinoshandura chetatu-way chine simba rekushandura rakawanda remahydrocarbon, carbon monoxide uye nitrogen oxides mugasi reutsi, kuitira kuti ichenese zvinosvibisa mweya zvakanyanya.
Deredza kushandiswa kwemafuta uye utsi: Kushanda kwesensa ye okisijeni yepamberi kunokanganisa zvakananga kushandiswa kwemafuta einjini uye kunaka kweutsi hunobuda. Kana sensa ye okisijeni yepamberi ikakundikana kana data risina kururama, zvinogona kukonzera kuwedzerwa kwemafuta, kudzikira kwesimba, gasi rinobuda mumhepo rakawandisa nezvimwe zvinetso.
Pamusoro pezvo, sensor ye okisijeni yekumberi inobatsirawo kuona kuti chigadziri che catalytic chenzira nhatu chinoshanda zvakanaka kudzivirira kukuvara nekuda kwehuwandu husina kunaka hwemusanganiswa. Kana sensor ye okisijeni yekumberi isina kunaka, zvinokurudzirwa kushandisa chishandiso chehunyanzvi chekuongorora kuti uone chikonzero chaicho chekukanganisa, pane kutsiva sensor zvakananga, kudzivirira mari isingakoshi.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
