Automobile ogisijeni ya ogisijeni.
Automobile ogisijeni ya ogisijeni niyo yingenzi ibitekerezo byigitekerezo cya eFI, kandi nigice cyingenzi cyo kugenzura imyuka ishimishije yimodoka, kandi nigice cyingenzi cyo guhuza ibidukikije no kunoza ubuzima bwiza bwa lisansi ya moteri yimodoka.
Hariho ubwoko bubiri bwa sensor ya ogisijeni, zirconiya na titanium dioxyde.
Sexeson Sensor ni ugukoresha ibintu byoroshye byo gupima ogisijeni mu itanura rinini cyangwa imiyoboro y'amazi, igahuza no guhuza ibicuruzwa mu bicuruzwa, bikoreshwa no guhuza ibicuruzwa bya oxyge mu bicuruzwa, bikoreshwa mu buryo bwo kuvugurura ibiza, bikoreshwa cyane mu gutwika amakara, gutwikwa amavuta, gutwikwa amavuta, gutwikwa amavuta n'izindi itanura rigenzura.
Sensor ya ogisijeni ikoreshwa mu kugenzura imiterere ya elegitoroniki.
Ihame ry'akazi
Sensor ya ogisijeni ikora kimwe na bateri, hamwe na element zirconia muri sensor ikora nka electrolyte. Ihame ryibanze ryakazi ni: Mubihe bimwe na bimwe (ubushyuhe bwinshi na cataryohe), itandukaniro ryibanda kuri ogisijeni hagati yimbere no hanze ya hao oxide ya hao oxide ya hao rikoreshwa mugukora itandukaniro, kandi ni irihe tandukaniro ryibanda ryibandaho, niko itandukaniro rito. Ibirimo bya ogisijeni mu kirere ni 21%, gaze ya exhaus nyuma yo gutwikwa neza ntabwo ikubiyemo ogisijeni ikubiyemo ogisijeni ikubiyemo ogisijeni nyinshi mu kirere.
Munsi ya Catalisi yubushyuhe bwinshi na platine, ogisijeni yometse kuri sensor ya ogisijenye irakoreshwa, bityo itandukaniro rya voltage ryakozwe, ibisohoka voltage yivanze ya 1V, kandi imvange ya dilute iri hafi ya 0v. Ukurikije ikimenyetso cya voltage cya sensor ya ogisijeni, igipimo cya lisansi kigenzurwa kugirango uhindure ubugari bwa lisansi, bityo kugenzura ibikoresho bya elegitoroniki sensor ninkuru ya ogisijeni kuri metero ya lisansi. Sensor ya ogisijeni irashobora kurangwa gusa mubushyuhe bwo hejuru (imperuka igera kuri 300 ° C) kandi irashobora gusohoka voltage. Irasubiza vuba kugirango ihindurwe muvanga hafi 800 ° C.
Inama
Zirconuum Dioxide Dioxden sensor yerekana impinduka zimvange yikimenyetso cyaka binyuze mu guhindura imyumvire ya voltage, na tinexide dioxide ya dioxide ya dioxide yerekana impinduka zivanze zinyuranye yo guhinduka. Sisitemu yo kugenzura ibikoresho bya elegitoroniki igenzura rya zirconia ntishobora kugenzura igipimo cya nyacyo cyikirere hafi yacyoga cyangiritse, mugihe cya Titimay Dioxy Dioxde yangiritse, mugihe cya Titimal Dioxy Dioxeri yangiritse, mugihe cya lisansi ya gitereki mugihe cyangiza moteri.
Ingano yinjiriro (inving ubugari bwa fagitire) yahinduwe nishami rigufi mugihe cyo gukosorwa kwa ogisijeni cyitwa gukosorwa igihe gito, bigenzurwa nibisohoka bya sensor ya ogisijeni.
Ikosora ryigihe kirekire ni agaciro kagenwa nishami rishinzwe kugenzura igenamigambi rishinzwe kugenzura amakuru akurikije impinduka zigihe gito cyo gukosora ikosora.
Amakosa rusange
Iyo sensor ya ogisijeni irananirana, mudasobwa ya sisitemu yo gutera amashanyarazi ntishobora kubona amakuru ya ogisijeni mu muyoboro uhindagurika, bityo bigatuma moteri igabanya umuvuduko udasanzwe, kandi ku nkuka kw'imikorere idahwitse, no kubura akarere, kwiyongera n'ibindi bicuruzwa. Kubwibyo, amakosa agomba kuvaho cyangwa gusimburwa mugihe gikwiye [1].
Uburozi
Uburozi bwa ogisijeni bukunze kugaragara kandi biragoye kubuza, cyane cyane gukoresha imodoka za Mandine ya Gasansi, ndetse na sensor nshya ya ogisijeni, irashobora gukora ibirometero bike. Niba ari uburozi buke bwo kuyobora, hanyuma ukoreshe ikigega cya lisansi yubusa kirashobora gukuraho iyambere hejuru ya sensor ogisijeni hanyuma ugisubize mubikorwa bisanzwe. Ariko, akenshi bitewe nubushyuhe bwinshi bwuburakari, bituma binjira imbere, bibangamira kubitandukanya ogisijeni bidakora, muricyo gihe ishobora gusimburwa gusa.
Byongeye kandi, uburozi bwa silicon bwa ogisijeni sensor nacyo kandi ni ibintu bisanzwe. Muri rusange, Sinica yabyaye nyuma yo gutwikwa ibikomoka ku muri Silicon bikubiye muri lisansi no gusiga amavuta, hamwe na gaze ya silicone yasohotse mu buryo budakwiye bwa gaske ya silicone bizatuma ibyuma bya ogisijeho bikatirwa, bityo amavuta meza kandi akoreshwa neza.
Iyo usana, ni ngombwa guhitamo neza no gushiraho gaskes Sensor, kugirango ibimenyetso bisohoka bya sensor ya ogisijeni bidahuye. ECU ntishobora gukosora igipimo cyumwuka-cya lisansi mugihe. Gutanga ibicuruzwa bya karubone bigaragarira cyane cyane nkubwiyongere bwa lisansi no kwiyongera kugaragara muburyo bwo kwibanda. Muri iki gihe, niba imyanda ikuweho, izasubira mubikorwa bisanzwe.
Ceramic
CERATIQ ya sensor ya ogisijeni irakomeye kandi itontoma, kandi ikomanga ibintu bikomeye cyangwa kuvuza umwuka ukomeye cyangwa uhuha kandi birananirana. Kubwibyo, birakenewe kwitonda cyane mugihe duhanganye nibibazo no kubisimbuza mugihe.
Umugozi wahagaritswe
Umutsinga wo kurwanya umusonga watwitse. Kuri sensor ya ogisijeni ishyushye, niba insinga zo kurwanya umushyushya zatwitse, biragoye gutuma sensor igera kubushyuhe busanzwe bwakazi no gutakaza imikorere yayo.
Umurongo uhagarika
Umuzunguruko w'imbere wa ogisijeni sensor irahagarara.
Uburyo bwo kugenzura
Kugenzura umushyurwa
Kuraho plug ya sensor harness ya ogisijeni, hanyuma ukoreshe ibitsina kugirango upime kurwanya pole yashyushya hamwe nicyuma muri sensor ya ogisijeni. Agaciro ko kurwanya ni 4-40ω (reba amabwiriza yicyitegererezo cyihariye). Niba itujuje ubuziranenge, gusimbuza sensor.
Gupima ibitekerezo bya voltage
Mugihe upima ibitekerezo bya SENESOR ya ogisijeni, ibikoresho byo gucomeka bya ogisijeni bigomba gucogora, kandi hagomba gusuzumwa hagomba gusuzumwa ibisaruro bya ogisijeni nkurutonde rwumuzunguruko. Ibitekerezo bya Voltage birashobora gupimwa kuva kumurongo mugihe cyo gukora kuri moteri (icyitegererezo zimwe na zimwe zirashobora kandi gupima voltage ya sentage ya sensor ya ogisijeni). Kurugero, urukurikirane rwimodoka zakozwe na Toyota Motor irashobora gupima voltage ya sensor ya oxyjen itaziguye kuva kuri ox1 cyangwa ox2 termils muburyo bwo kumenya neza sock).
Mugihe upima ibitekerezo bya SENESOR ya ogisijeni, nibyiza gukoresha imiyoboro ya poirter ifite urwego ruto (mubisanzwe 2V) hamwe nimpopence nyinshi (kurwanya imbere hejuru ya 10m). Uburyo bwihariye bwo kumenya ni ibi bikurikira:
1. Hindura moteri ishyushye ubushyuhe busanzwe bwakazi (cyangwa ikora kuri 2500r / min nyuma yo gutangira 2min);
2. Huza ikaramu mbi ya lobimtage ya multimeter ihagarara kuri e1 cyangwa amatora mato ya bateri muri sock ya perket, hamwe na jack nziza kuri ox1 cyangwa ox | Ku myambarire ya wiring plug ya sensor ya ogisijeni.
3, reka moteri ikomeze kwiruka ku muvuduko hafi 2500r / min, hanyuma urebe niba imvugo ya Volhoter ishobora guhiga inyuma ya 0-1V, hanyuma wandike umubare wa Voluteter Pointer Interineti. Mubihe bisanzwe, hamwe niterambere ryibitekerezo, ibitekerezo bya voltage ya sensor ya ogisijeni izahora ihinduka hejuru no munsi ya 0.45v, hamwe na voltage ya extrack igomba guhinduka inshuro zirenga 8 mugihe cya 10.
Niba ari munsi yinshuro 8, bivuze ko sisitemu ya ogisijeni cyangwa gahunda yo gutanga ibitekerezo idakora neza, ishobora guterwa na karubone hejuru ya sensor ya karusiyo, kugirango imyizerere igabanuka. Kuri iyi ntego, moteri igomba gukoreshwa saa 2500r / min kumanota 2 kugirango ukure kubitsa karubone hejuru ya sensor ya ogisijeni, hanyuma ugenzure voltage. Niba imvugo ya Volhoter iracyahinduka buhoro nyuma yuko karubone imaze gukurwaho, yerekana ko SENSEN yangiritse, cyangwa ibiganiro bya mudasobwa kugenzura umuzenguruko ni amakosa.
4, ogisijeni ya sensor igaragara igenzura
Kuraho sensor ya ogisijeni kuva mu muyoboro usakuza kandi urebe niba umwobo winjiye wambaye imyenda ya sensor wahagaritswe kandi intangiriro ya Ceramic yangiritse. Niba byangiritse, gusimbuza sensor.
Amakosa arashobora kandi kwiyemeza mukwitegereza ibara ryigice cyo hejuru cya sensor:
1, imvi zoroheje hejuru: Iri ni ibara risanzwe rya sensor ya ogisijeni;
2, Hejuru Hejuru: Yatewe no kwanduzwa kwa silicon, sensor ya ogisijeni igomba gusimburwa muri iki gihe;
3, hejuru yumukara (nkuko bigaragara ku gishushanyo 1): biterwa no guhumanya kwamagana, niba bikomeye, bigomba no gusimbuza sensor;
.
Niba ushaka kumenya byinshi, komeza usome izindi ngingo kururu rubuga!
Nyamuneka uduhamagarire niba ukeneye ibicuruzwa nkibi.
