Chii chinonzi mota pamberi peokisijeni sensor
Iyo mota yekumberi okisijeni sensor inzwa yeokisijeni yakaiswa pamberi peiyo nzira nhatu inoshandura inoshandura. Basa rayo guru nderokuona huwandu hweokisijeni mujini inopedza gasi, uye kupa ruzivo rwekutsvaga kuECU (electronic control unit) nenzira yemagetsi emagetsi. Iyo ECU inodzora vhoriyamu yejekiseni yemafuta muvharo yakavharwa zvinoenderana neiyo okisijeni yekumisikidza mumhepo yekuburitsa gasi kugadzirisa iyo mhepo-mafuta reshiyo yemusanganiswa kuti ive nechokwadi chekuti iri padhuze neiyo theoretical kukosha, nekudaro optimize kupisa kwemoto uye kuderedza kusvibiswa kwemhepo.
Nheyo yekushanda yekumberi kweokisijeni sensor yakavakirwa pazirconia ceramic machubhu, ane porous platinum electrodes akaiswa pamativi ese. Pane imwe tembiricha, nekuda kwekusiyana kweokisijeni kumativi ose maviri, mamorekuru eokisijeni ari kudivi repamusoro-soro anosanganiswa nemaerekitironi ari paplatinamu electrode kuita maion eokisijeni, kuitira kuti electrode ichajike zvakanaka, uye maion eokisijeni anofamba achienda kudivi reokisijeni yakaderera kuburikidza neelectrolyte, zvekuti electrode ichajaidzwa zvisina kunaka, zvichiita kuti pave nemusiyano. Kana musanganiswa wacho wakaonda, iyo okisijeni yemukati mumhepo yakakwira uye mutsauko unogona kuve mudiki. Apo musanganiswa wacho wakaiswa, iyo okisijeni yemukati mumhepo yakaderera uye iyo inogona kusiyana yakakura. Iyo ECU inogadzirisa jekiseni remafuta zvinoenderana neiyi inogona mutsauko yekuvhara-loop control.
Iyo yekumberi yeokisijeni sensor inoiswa pamberi peiyo nzira nhatu-catalytic converter uye inonyanya kuona iyo oksijeni yekuisa mujini inopedza gasi. Kana iyo data yakaonekwa nechemberi yeokisijeni sensor uye kumashure kweokisijeni sensor yakafanana, inogona kuratidza kuti pane dambudziko ne-tatu-way catalytic converter, inoda kuongororwa uye kuchengetedzwa.
Basa guru remotokari yekumberi kweokisijeni sensor ndeyekuona iyo okisijeni iri mukati meinjini inopopotera, uye kushandura ruzivo urwu kuita chiratidzo chevoltage kuendesa kune injini komputa (ECU), kuitira kuti uone iyo yakavharwa-loop kutonga kwemhepo-mafuta ratio. Kunyanya, iyo yekumberi yeokisijeni sensor inotarisisa iyo oksijeni yemukati mukupopota, ichibatsira iyo ECU kugadzirisa vhoriyamu jekiseni remafuta, kuchengetedza yakaringana mhepo-mafuta reshiyo, optimize kushanda kwemafuta, kuderedza kushandiswa kwemafuta, uye kuderera kuburitswa kwemagasi anokuvadza akadai secarbon monoxide (CO) uye nitrogen oxides (NOx). ,
Kushanda musimboti
Iyo yekumberi yeokisijeni sensor inoshanda sebhatiri, uye chikamu chayo chepakati ndiyo element zirconia, inoshanda pakupisa kwakanyanya uye inogadziriswa neplatinamu. Iyo sensor inoshandisa iyo oksijeni yekumisikidza musiyano pakati pemukati nekunze kwe zirconia kuburitsa mutsauko ungangoita, uye iyo yakakura mutsauko wekusimbisa, iwo mukuru mutsauko unogona kuitika. Kuwanda kweokisijeni mugasi rekubuda nemhepo kwakadzikira kana kuchienzaniswa nekuwanda kweokisijeni mumhepo, uye musiyano uyu wekusangana unoburitsa chiratidzo chemagetsi pakati pemagetsi. Iyo ECU inogadzirisa jekiseni remafuta maererano nezviratidzo izvi, kuve nechokwadi chekuti chiyero chemhepo-mafuta yemusanganiswa chiri padyo neiyo theoretical optimal value.
Installation position
Iyo yekumberi yeokisijeni sensor inowanzoiswa pamberi peiyo nzira nhatu-catalyst uye inoshandiswa kuona iyo oksijeni yekuisa mujini inopedza gasi. Iyo afteroxygen sensor yakaiswa kuseri kwetatu-nzira catalytic converter kuti ione iyo oxygen kuungana kweiyo epoust gasi mushure mekunatswa kwecatalytic. Kana iyo okisijeni data data yakawanikwa neokisijeni sensor pamberi uye mushure yakafanana, inogona kuratidza kuti iyo nzira nhatu inoshandura inoshandura yakundikana.
Kutadza kushanda
Kana iyo yekumberi yeokisijeni sensor ikatadza, inogona kukonzera matambudziko senge isina kugadzikana isingaite kumhanya uye yakawandisa mafuta. Nekuda kwekuti ECU haikwanise kugadzirisa jekiseni remafuta zvichibva pane chaiyoiyo okisijeni siginecha, kuita kweinjini kunoderera uye kuburitsa kunowedzera.
,Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
