Basa re sensor yemota yekumashure yeokisijeni
Muhurongwa hwekudzora kubuda kwemhepo mumotokari, sensor yekumashure yeoxygen, kunyangwe iri diki, inoita basa rakakosha se "tail gas monitor". Kushanda kwayo kunokanganisa zvakananga mashandiro einjini uye mhando yeutsi hunobuda muinjini. Kunzwisisa mashandiro ayo, zviratidzo zvekukanganisa, uye zvikonzero zvakakosha kune varidzi vemotokari mukutyaira kwavo kwezuva nezuva nekugadzirisa mota.
Basa guru re rear oxygen sensor nderekutarisa kushanda zvakanaka kwe three-way catalytic converter. Inoiswa kuseri kwe three-way catalytic converter uye inoona huwandu hwe oxygen mu purified exhaust gas, ichidzosera data ku engine electronic control unit (ECU). ECU inoenzanisa data kubva ku front oxygen sensor (yakaiswa pa exhaust manifold, ichitarisa huwandu hwe oxygen mu exhaust gas yekutanga) kuti ione kana three-way catalytic converter iri kushanda nemazvo. Mumamiriro ezvinhu akajairwa, mushure mekucheneswa ne three-way catalytic converter, huwandu hwe oxygen mu exhaust gas hunoramba hwakagadzikana, uye kushanduka kwesignal kwe rear oxygen sensor kudiki zvikuru pane kwe front oxygen sensor; kana musiyano wezviratidzo pakati pezviviri ukaderera kana kutoenderana, zvinoratidza kuti three-way catalytic converter ingave yakundikana uye haigone kushandura magasi anokuvadza zvinobudirira. Pamusoro pezvo, data remhinduro kubva ku rear oxygen sensor rinobatsirawo ECU mukugadzirisa huwandu hwe fuel injection, zvichiita kuti injini ishande zvakanaka.
Kana sensor yekumashure yeoxygen ikakundikana, mota icharatidza zviratidzo zvakasiyana-siyana zvisina kujairika, zvichikanganisa kutyaira uye mashandiro emotokari. Chiratidzo chinonyanya kuoneka ndechekushanda kwechiedza cheinjini. Kana chiratidzo chesensor chisina kujairika, komputa iri mubhodhi ichatanga chiedza chekunyevera kukanganisa. Uchishandisa mudziyo wekuongorora weOBDII, makodhi ekutadza akakodzera akadai seP0136 kusvika kuP0141 anogona kuverengwa. Kudzikira kwekushanda kwesimba kunowanzoitikawo. Nekuda kwekusakwanisa kwesensor kuratidza data rehuwandu hweokisijeni nemazvo, kutonga kweECU kwehuwandu hwemafuta anoiswa mumotokari kunova kusina kururama, zvichikonzera kupisa kwakanyanya kana kusina kusimba, kudzikira kwekushanda kwemoto, kumhanyisa zvishoma nezvishoma, simba risina kukwana rekukwira, uye kushanduka kwekumhanya, kudedera kwemuviri, kana kutomira kweinjini isina kushanda. Panguva imwe chete, kushandiswa kwemafuta kuchawedzera zvakanyanya. Data rinoratidza kuti kutadza kwesensor yekumashure yeoxygen kunogona kukonzera kuwedzera kwe5% kusvika 10% muhuwandu hwemafuta anoiswa mumotokari. Kune mota yemhuri ine makiromita zviuru makumi maviri pagore, kushandiswa kwemafuta ekuwedzera pagore kunogona kusvika marita mazana mapfumbamwe, zvichikonzera kurasikirwa kukuru kwehupfumi. Kubuda kwemhepo kuchavawo kusina kujairika. Gasi reutsi risina kucheneswa rinogona kuita serakasviba uye rine hwema hunorwadza, kwete kungosvibisa nharaunda chete asiwo zvichiita kuti mota ikundikane bvunzo yekubuda kweutsi pakuongorora kwegore negore. Dzimwe mota dzinogonawo kuratidza zviratidzo zvakavanzika zvakaita sekutonhora zvishoma, kuzununguka kudiki panotanga mhepo inotonhodza, uye kutomira kweinjini, izvo zviri nyore kufuratira varidzi.
Zvinokonzera kutadza kushanda kwesensor yeokisijeni kumashure zvakaoma uye zvakasiyana-siyana. Zvinogona kuiswa muzvikamu zvitatu. Chekutanga, matambudziko emhando yemafuta. Mafuta asina kunaka ane sarufa, lead, nezvimwewo, achaumba denderedzwa rekusvibiswa pamusoro pesensor mushure mekutsva, zvichikanganisa kupararira kwemaion eokisijeni uye zvichikonzera kunonoka kwechiratidzo kana kukanganisa; silicon additives ichagadzira makristaro machena pane chinhu chinonzwa, zvichikonzera kudzikira kamwe kamwe kwekunzwisisa neanopfuura 60%. Chechipiri, kukwegura kwedunhu nezvikamu. Sensor wiring harness inoonekwa pakupisa kwakanyanya uye hunyoro hwakanyanya kwenguva yakareba, uye insulation layer inokurumidza kukwegura, oxidation yema connectors inowedzera kuramba kwekubatana, uye circuit yekupisa yakatyoka ichadzivirira zvikamu kuti zvisasvike 300°C working threshold, zvichikonzera zviratidzo zvisingawanzo gamuchirwa neECU. Chechitatu, carbon deposits uye kusvibiswa. Kupisa kusina kukwana muinjini kunoburitsa carbon deposits, kana mafuta, guruva, nezvimwewo, zvinopinda munzvimbo yekushanda yesensor, zvichifukidza pamusoro pechinhu chinonzwa uye zvichikanganisa kuwanikwa kweoxygen. Kunyanya mushure mekunge mota yafamba makiromita anopfuura 80,000, huwandu hwekabhoni inogona kusvika 0.2-0.5mm, zvichideredza zvakanyanya mashandiro e sensor.
Pakubata nekutadza kwesensa yeokisijeni yekumashure, varidzi vemotokari vanofanira kutora matanho panguva yakakodzera. Pakutyaira kwezuva nezuva, sarudza nzvimbo yemafuta yakakodzera yekuwedzera mafuta uye shandisa macleaner system emafuta nguva dzose kuderedza kukuvara kwesensa kunokonzerwa nekusvibiswa; tevera mazano ari mubhuku rekugadzirisa mota, tarisa curve yechiratidzo chesensa makiromita ese zviuru makumi matatu, uye chenesa nehunyanzvi makiromita ese zviuru makumi mashanu kudzivirira kuungana kwecarbon deposits. Kana mota ikaratidzwa zviratidzo zvekukanganisa zvataurwa pamusoro apa, inofanira kuyedzwa nekukurumidza panzvimbo yekugadzirisa yehunyanzvi. Kuburikidza nekuenzanisa waveform nedzimwe nzira, simbisa mamiriro esensa. Pakutsiva sensor, zvinokurudzirwa kusarudza zvikamu zvefekitori zvepakutanga. Mwero wekudzokororwa kwezvikamu izvi i8% chete, iyo yakaderera zvikuru pane 35% yezvikamu zveaftermarket. Mushure mekutsiva, maparameter eECU anofanirwa kudzoserwa patsva kuti ive nechokwadi chekuti mota yadzokera pakushanda kwayo kwakajairika.
Chinoongorora okisijeni chekumashure chikamu chakakosha chehurongwa hwemagetsi emota. Kushanda kwayo kwakasimba ndiko kunoita kuti injini ishande zvakanaka uye kuti utsi hwemhepo hurambe huchienderana nezvinodiwa. Mota inogona kugara iri mumamiriro akanaka chete kana ikanzwisisa zvikanganiso nezvikonzero, uye kugadzirisa nguva nenguva, zvichiita kuti igare iri mumamiriro akanaka, zvichideredza mari yekushandisa uye zvichibatsira pakuchengetedza nharaunda.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
