Lambda SENSOR: Zizindikiro ( "Priora", "Octavia", "Renault Megane 2," "Ford Focus 2")

M'nkhani ino mudzaphunzila mmene lambda kafukufuku, zizindikiro za kulephera mfundo, taganizirani nayenso. Limatchedwanso mpweya kachipangizo. Iwo waikidwa mu utsi kachigawo ka kuyaka mkati injini magalimoto. Komanso, kachipangizo aikidwa onse pa petulo ndi injini dizilo.

mfundo zikuluzikulu za kachipangizo mpweya

Lambda kafukufuku ndi ofanana mu mfundo ya ntchito, chifukwa selo electrochemical wopangidwa mwa electrolyte olimba ceramic zochokera zirconia. Komanso pogwiritsa ntchito ziwiya zadothi alloying yttria. Kupopera pamwamba ndi wosanjikiza woonda ndi ntchito pulatinamu. Iwo likukhalira kuti elekitirodi mmodzi alandira utsi mpweya, pokhala winayo - mpweya wa mumlengalenga. Ndi kupyolera mu fanizoli amapezeka magawo mpweya ntchito ndi mpweya yachibadwa mumlengalenga. Komanso Dziwani kuti ntchito kothandiza kwambiri ikuchitika pa kutentha pamwamba madigiri 300. Ndi pansi pa Kutentha electrolyte wa zirconium akuyamba kuchita panopa. Ndipo tsopano ndi nthawi kuphunzira zimene umakhudza mmene lambda kafukufuku. Zizindikiro "Priora" Mwachitsanzo, adzaona, ngakhale pa mlanduwu.

Mfundo zikugwira ntchito ya lambda kafukufuku

Chifukwa chakuti pali kusiyana mu zili Unyinji wa mpweya, linanena bungwe voteji limapezeka kudutsa maelekitirodi wa sensa. Kuonjezera tilinazo chipangizo pa kutentha otsika, mwachitsanzo patchuthi injini chiyambi, m'pofunika ntchito simuchita magetsi. koyilo magetsi ili mu ceramic thupi lambda kafukufuku. Iwo ali kugwirizana kwa galimoto dongosolo magetsi. Pali mpweya kachipangizo amafotokozera, ozikidwa pa titaniyamu woipa. Iye samasintha kukana kwawo pamene injini ikulira. Ndi mfundo imeneyi ntchito lambda kafukufuku. Zizindikiro VW Golf 3 ndi amodzi mwa magalimoto zoweta.

Mpweya kachipangizo Job

Panthawi imeneyi, pamene pali kuyamba-mmwamba n'kumawotha mpaka injini, injini umagwira popanda deta ikuchokera lambda kafukufuku. Lonse mpweya mafuta chiŵerengero kudzudzulidwa limapezeka pa deta analandira kwa zipangizo zina. Makamaka izi malo sensors vavu mu liwiro fulumizitsa, injini kutentha, engine. Mbali yaikulu ya lambda kafukufuku zochokera zirconium - kuti ndi kupatuka pang'ono kuchokera ponseponse mu mpweya okhutira kusanthula zikuchokera kusakaniza mafuta limapezeka kusintha linanena bungwe voteji mu zosiyanasiyana 0.1-0.9 Volts.

masensa titaniyamu mpweya

Palinso masensa zopangidwa titaniyamu woipa. Ndiye, pamene pali kusintha kachigawo Unyinji wa oxygen mpweya wa utsi, iwo pang'onopang'ono kusintha mu kukana buku. voteji mu M'badwo wa masensa ya mamangidwe zimachokeradi. Ali zovuta kuposa zirconium, ntchito pa magalimoto odula monga BMW, Nissan, "nyamazi". Pa zipangizo galimoto bajeti zochokera titaniyamu, zambiri osati ntchito chifukwa cha mtengo awo apamwamba. Pa magalimoto a sing'anga ndi otsika kalasi mtengo zirconia mpweya sensa ntchito. Zizindikiro "Renault Megane 2" akusonyeza anthu amene si osiyana ndi anthu pano pa magalimoto zoweta.

Kusiyana lambda probes

Tikumbukenso kuti makhalidwe ntchito pa zimatulutsa mpweya ndinu yemweyo, sikudalira amene Mlengi. Kusiyana komwe kulipo ndi zomwe phukusi kukula kwa zinthu izi. Zingakhalenso ena kugwirizana ena, pamakhala kusiyana mu cholumikizira lapansi. masensa onse, monga momwe tafotokozera pamwambapa, ndi mkangano kapena ayi. Choncho, iwo amasiyana chiwerengero cha mawaya kulumikiza. Malinga ndi zipangizo kusiyana zotsatirazi: mwina zirconium kapena titaniyamu. Pomaliza posachedwapa chotenthetsera nthawizonse ali ndi mtundu wofiira. Palinso mitundu ya injini dizilo. Komanso burodibandi. Inu simungakhoze kuika pa injini mafuta lambda kafukufuku. Zizindikiro ( "Skoda Octavia" ndi chidwi ziziyenda ambiri) ali limodzi ndi kusuta ya malamulo zolakwa ndi kufotokoza mwachidule.

N'chifukwa chiyani amalephera lambda kafukufuku

pafupipafupi kwambiri chifukwa cha kulephera msanga ndi osauka khalidwe mafuta. Iron ndi kutsogolera, amene akhoza kupezeka mu mafuta osauka yomweyo kuononga maelekitirodi pulatinamu. Choncho, kulephera kwa sensa mpweya, izo sizingakhoze bwino kuchotsa umboni wonse. Ngati scraper mphete ndi kupanga amphamvu, mu utsi chitoliro udzapeza kuchuluka kwa mafuta. Ndi chifukwa cha kulephera msanga wa kachipangizo oxygen. Ngakhale onse ngozi mwadzidzidzi mu kachipangizo mpweya ali pang'ono zosungunulira kapena detergent, inu athanso kuwauza kuti linathyoka. Iye sakufuna kuona kupeza njira izi. Chiwonongeko cha lambda kafukufuku amapezeka mlandu pamene dongosolo utsi zimachitika pomwe kutero Sikungawathandize. Ziwiya zadothi ndi osalimba kwambiri, kotero kuti nkhonya lakuthwa ukhoza kuononga izo. Pamene zosayenera unsembe wa ngodya poyatsira kapena pa mwauchidakwa wolemera kusakaniza mafuta mpweya ndi amphamvu Kutentha kwa nyumba kachipangizo. Izi zimapangitsa kulephera msanga.

zifukwa zochepa wotchuka kulephera

Chonde dziwani kuti pamene khazikitsa ndi lambda kafukufuku sangathe ntchito zosiyanasiyana mankhwala ena omatira, zomwe ndi zochokera pakachitsulo. Mukhozanso kuwononga kachipangizo mpweya, ngati nthawi yambiri kuyesa kuyamba injini, kupanga chete kakang'ono pakati pa kuyesa. Malinga injini Sikuyaka. Izi kumawachititsa chakuti kusakaniza mafuta mpweya adzamanga m'dongosolo utsi. Patapita kanthawi izo udzayaka ndi kulenga kuphulika wamphamvu. Ngakhale zosalongosoka kukhudzana kapena lalifupi dera mu dera linanena bungwe, akhoza kuwononga chipangizo. Nawo zinthu gwero zimasiyanasiyana mu osiyanasiyana makilomita 30..70 zikwi. Kwakukulukulu zimadalira zinthu imene yokumba udzachitika. The moyo wopambana mu masensa limene pali zina magetsi. Mu ambiri a magalimoto umagwiritsidwa chotero kapangidwe lambda kafukufuku. Zizindikiro ( "Ford Focus 2" kapena "Skoda" zopezeka lanu) ndi chimodzimodzi. Chotero, inu mukhoza oterewa ndi paokha ngati bwino kuzindikira zizindikiro zonse.

Pafupipafupi breakage kachipangizo

Mwa zolephera wotchuka Tingaone wosweka Kutentha amafotokozera, ndi imfa ya zotengeka. Chifukwa liwiro posachedwapa wa amachepetsa chipangizo. Chinthu chofunika kwambiri - yesetsani m'malo lambda kafukufuku ndi akutsanza iliyonse. The zamagetsi ulamuliro wagawo simungathe kuzindikira chizindikiro chachilendo. Choncho, kuwukonza kusakaniza mafuta ndi pulogalamu yoyeseza sadzafika. Dziwani kuti ngati kachipangizo mpweya akugwira ntchito bwinobwino m'dziko lathu (osauka kwambiri mafuta), ndipo moyo wake unali mwachionekere zaka zoposa zitatu, simungathe ngakhale kulumikiza diagnostician. Basi ayenera m'malo kachipangizo oxygen. Zizindikiro "Skoda" limasonyeza momveka bwino pamene wagundidwa 70 chikwi. Km. Ena mwa chitsanzo chomwecho masensa mpweya ndi onse akhale nawo moyo pang'ono makilomita oposa 30 zikwi.

Kodi asankhe kachipangizo wolakwika

Ngati pali opareshoni wosakhazikika olimbana imathamanga otsika, ndikusangalala ngati injini "troit." Ndipo kuonjezera kumwa mafuta, mphamvu galimoto worsens. Nthawi zambiri anamva chochititsa mantha, wafting kwa chothandizira mukachoka kutchinga injini. N'zothekanso kuwonjezera (kwambiri) kwa kutentha chothandizira. Nthawi zina zimachitika Kutentha amenewa, zitsulo usavutike chabe. Mu ena magalimoto cholakwika akhoza adzaweruzidwa ndi chenjezo nyale Fufuzani Engine. Koma, mwatsoka, si onse amagetsi dongosolo kulamulira angazindikire ndi kusonyeza vuto la chinthu ichi.
