Kodi sensa ya oxygen ili kuti? Kodi mungayang'ane bwanji mpweya wa oxygen?

Kawirikawiri, chipangizochi chatsopano. Tiyeni tiyang'ane kumene khungu la oxygen liri mu galimoto , momwe mungayesere ntchito yake. Komanso timaphunzira zizindikiro za kukanika ndi china chirichonse chokhudza sensa iyi.

Zakale za mbiriyakale

Chidutswa ichi chikhoza kuonedwa kuti ndi chotchuka kwambiri pakati pa masensa ena onse ndi masensa m'galimoto. Akatswiri odziwa zamagalimoto amatha kugwirizana nazo. Magetsi a oxygen akhalapo kale, si zachilendo. Pulofiti yoyamba ya lambda inali mtundu wowonongeka popanda kutentha. Chipangizocho chinali kutenthedwa ndi kutentha kwa mpweya wotulutsa mpweya. Zinatengera nthawi yotentha.

Zaka zambiri zapitazo, zochitika zachilengedwe padziko lonse zinali kuwonongeka. Chifukwa chake, kunali kofunikira kutenga njira zowonjezera kuopsa ndi poizoni. Zofunika kwa magalimoto zakhala zolimba. Panthawi imeneyi, sensa inayamba kusintha ndikusintha. Anali ndi chimbudzi chapadera.

Momwe kafukufuku wa lambda amagwirira ntchito

Kuti mudziwe momwe mungayesere chitsimikizo cha mpweya wa oxygen, muyenera kukhala ndi lingaliro la momwe ziwalozo zimagwirira ntchito. Mbali yogwira ntchitoyi ndi mtundu wa ceramic zomwe zili ndi platinamu. Izi zimagwira ntchito kutentha.

Kutentha kutentha kumafika madigiri 350 kapena kuposa. Ngakhale kuti kutentha kumatha kutentha mpaka kumapangidwe ake, kukonzekera kwa mafuta osakaniza kumalamulidwa molingana ndi deta yomwe imachokera ku masensa ena. Kuti khungu liziwotha mofulumira, lili ndi chimbudzi chogwiritsira ntchito magetsi. Pankhani ya ntchito, sivuta. Magetsi otulutsa mpweya amatsegula makina opangira mphamvu, ndipo amawonanso kusiyana kwa mpweya wa okosijeni kumatuluka ndi kutentha. Kenako, lambda imatumiza deta ku ECU. Wotsiriza amapereka malangizo okonzekera kusakaniza ntchito.

Kodi sensa ya oxygen ili kuti?

Choncho, kwa injini zochokera ku "AvtoVAZ" zomwe zili ndi 1.5 lita, pulogalamu ya lambda ili mukutuluka. Zolondola kwambiri, pa chubu cholandira. Chigawochi chimangolengedwa kuchokera pamwamba, kutsogolo kwa resonator, kapena pamaso pachepere pakakhala palibe chisanafike.

Ma injini 1.6 malita kuchokera ku AvtoVAZ, chimagwiritsiranso ntchito dongosolo lakutentha. Choncho, apa timagwiritsa ntchito mapulogalamu awiri a lambda. Onse awiri ali pa osonkhanitsa. Pa magalimoto amenewa, khwasani imodzi kapena masensa awiri. Ngati injini ikugwiridwa ndi chikhalidwe cha "Euro-2", ndiye kuti chinthucho ndi chimodzi. Ngati pansi pa "Euro-3", padzakhalanso mapulogalamu awiri a lambda. Kotero pa magalimoto onse "Lada Priora." Kodi mungayang'ane bwanji mpweya wa oxygen? Ndikofunika kulichotsa ndikuonetsetsa kuti ntchitoyo ndiyothandiza mothandizidwa ndi zipangizo zapadera - multimeter.

Chifukwa chiyani kafukufuku wa lambda akulephera?

Zifukwa zomwe izi zikulephera, zingakhale zosiyana. Kawirikawiri izi zimakhala zovuta kwambiri. Komanso, kuthawa kumatheka chifukwa cholowera kunja kwa mpweya ndi mpweya wotulutsa mpweya. Chimodzi mwa zifukwa zomwe zimakhala zikupitirira.

Zimayambira chifukwa cha msonkhano wosauka wamagalimoto kapena ntchito yoyipa ya kutsegula. Nthawi zambiri kachilombo kamatuluka chifukwa cha kugwidwa, kusokonezeka kapena kusakhazikika. Palinso zotheka kuwonongeka kwa makina.

Zizindikiro za kukanika

Nthawi zambiri zolakwitsa zimachitika, chifukwa chachikulu chomwe chimakhala mpweya wokha. Momwe mungayesere izo zimadalira zizindikiro za kusagwira ntchito. Taganizirani izi. Chizindikiro chachikulu chomwe chimanena kuti kafukufuku wa lambda ndi wolakwika ndi kusintha kwa magalimoto. Zoona zake n'zakuti pambuyo poti sensa imatha, ubwino wa mafuta umasokonekera kwambiri. Mwachidule, palibe amene amachititsa udindo wokonzekera chisakaniziro - mafuta oyendetsedwa ndi osayendetsedwa. Mulimonsemo, kupatula mwinamwake wotsirizira, sensa imatha nthawi yomweyo, koma pang'onopang'ono.

Ambiri ambiri samadziwa komwe khungu la oksijeni lili, momwe angayang'anire ntchito yake, ndi zina zotero. Sadzizindikira nthawi yomweyo kuti chinthucho n'cholakwika. Koma kwa eni ake ogwira ntchito galimoto kuti amvetse ndi kulingalira chifukwa chake ntchito ya injini yasintha, sizidzakhala zovuta. Njira yolepheretsa kuperewera kwa maselo ingagawidwe muzigawo zingapo zazikulu. Pazigawo zoyamba, chinthucho chimangosiya kugwira ntchito bwinobwino - nthawi zina injini ikuyendetsa soda. Chifukwa cha ichi, kuyendetsa galimotoyo kumawongolera - kuyambiranso kukuyandama, ntchito yosasunthika ikuwoneka popanda ntchito. Zosintha zimatha kusinthasintha m'zinthu zazikulu. Zimenezi zimapangitsa kuti chiwerengero cha mafuta osakaniza chiwonongeke.

Pakali pano, makinawo amatha kungogwedeza popanda zifukwa zomveka, zomveka zomveka za uncharacteristic, ndipo nyali yomwe ili pazithunzi ikuyatsa. Zisonyezo zonsezi zikusonyeza kuti lambda ili kunja kwa dongosolo ndipo yayamba kale kugwira ntchito molakwika. Ndikofunika kudziwa momwe mungayang'anire sensa ya oksijeni kuti mukonze vutoli m'kupita kwanthawi. Kenaka ntchito ya lambda imaima pamoto ozizira. Pankhani imeneyi, galimotoyo idzadziwitse mwiniwake za vutoli. Mwachitsanzo, mphamvu idzagwetsa mofulumira, padzakhala pang'onopang'ono zotsatira za mafuta. Milandu imamveka kuchokera pansi pa nyumba, galimoto imatha. Koma chizindikiro chofunika kwambiri ndi choopsa ndi injini yowonjezera. Ngati mumanyalanyaza zizindikiro zonse zomwe zikufuula kale za kusagwira ntchito, kulephera kwathunthu kumatetezedwa. Dalaivala sakudziwa momwe angayang'anire sensa ya oksijeni. Choncho, kupweteka kumabweretsa mavuto aakulu.

Ngati simukuchita chilichonse

Woyendetsa galimoto adzakhala woyamba kuvutika, chifukwa mafuta akuwonjezeka, ndipo mpweya wotulutsa mpweya umakhala fungo lonunkhira ndi zitsulo zakuthwa kuchokera ku chitoliro. Pankhani yamagalimoto amakono okhala ndi zamagetsi ambiri, omwe amadziwa momwe angayang'anire mmene magetsi amathandizira, kutsekedwa kumatsegulidwa. Mu mkhalidwe uwu, magalimoto alionse pa galimoto sangatheke. Koma cholakwika kwambiri ndi kupweteka. Galimotoyo sapita konse kapena sizingayambe. Izi zikudzaza ndi kulephera kwathunthu kwa injini. Mukakhala kuti mukuvutika maganizo, mpweya wonse mmalo mwa chitoliro chotulutsa mpweya umalowa mumlengalenga. Mabeleki akamachitidwa , kafukufukuyo amatha kuona poizoni ndikupereka chizindikiro cholakwika. Izi zidzateteza kwathunthu dongosolo la jekeseni. Chizindikiro chachikulu cha kupanikizika ndikutaya mphamvu ya injini. Izi zingamveke pamene mukuyendetsa mofulumira. Komanso kuchokera pansi pa hood kumveka kugogoda ndi kuwomba, fungo. Poyamba, oyendetsa galimoto amayenera kudziwa momwe angasinthire carburetor. Tsopano palibe chomwe chasintha - nkofunikira kukumbukira momwe mungayang'anire chojambulira mpweya (VAZ-2112 ndi zosiyana).

Zogwiritsira ntchito pogwiritsa ntchito zamagetsi

Kuti mudziwe chomwe chiwerengero cha lambda chiri, ndizotheka kokha ndi chithandizo cha zipangizo zamakono. Oscilloscope yamakono ndiyenso kuyesa. Akatswiri amadziwa momwe angayesere kafukufuku m'njira zina (multimeter), koma mutha kudziwa ngati chinthucho chikugwira ntchito kapena chosweka.

Musanayambe kuyang'ana injini ya oxygen, m'pofunika kuyamba injini. M'nyumba yamtendere, kafukufuku sangathe kusonyeza chithunzi chake chonse chogwira ntchito. Ngati pali zolakwika zochepa kuchokera ku zikhalidwe, gawolo liyenera kusinthidwa ndi latsopano.

Zolakwika

Ngati pali vuto ndi sensa, magalimoto amayesa kulongosola izi m'njira iliyonse. Mukhoza kulumikiza chipangizo chapadera ku chingwe chodziwitsa, ndipo chirichonse chidzawonekera. Galimoto yamagetsi imadziwa momwe mungayesere mphamvu ya mpweya. Ngakhalenso magalimoto a VAZ ali ndi dongosolo lachidziwitso. Zolakwitsa zimawerengedwa kuchokera P130 mpaka P141 - izi ndizomwe zimayenderana ndi lambda. Kawirikawiri, mauthenga amawoneka omwe akugwirizanitsidwa ndi matenda osokoneza bongo m'madera oyendetsa. Chifukwa cha ichi, ECU imalandira zambiri zolakwika. Mukhoza kuyesa kupuma, koma ndibwino kuti mutenge mpweya wabwino. Momwe mungayesere kuti mugwire ntchito, mukudziwa kale.
