Sensor yeKudzvanywa Kwemuchina: "Ziso reData" reInjini
Chinoongorora kumanikidzwa kweinjini (chinopfupikiswa seMAP sensor) chinhu chakakosha cheD-type fuel injection system mumainjini emagetsi anogadzira mafuta, chinoshanda se "pressure detective" yeinjini. Chinogara chichitarisa shanduko dzepressure muinjini inopinda uye chinopa hwaro hwakakosha hwekuita sarudzo yeinjini control unit (ECU).
Yakabatana ne intake manifold kuburikidza ne vacuum tube uye inogona kubata nemazvo kushanduka kwe pressure mu intake manifold mumamiriro akasiyana ekushanda, ichiishandura kuita masaini emagetsi uye ichiitumira kuECU. Panguva yekumhanyisa mota, intake pressure inowedzera, uye sensor inotumira chiratidzo nekukurumidza, icho ECU inobva yawedzera huwandu hwe injection yemafuta kuti ipe simba rakakwana kuinjini; panguva yekudzikamisa speed, intake pressure inoderera, uye ECU inoderedza injection yemafuta, ichidzivirira kutambisa mafuta uye ichivandudza kushandiswa kwemafuta.
Zvinogonawo kubatsira ECU kugadzirisa nguva yekupisa, zvichiita kuti musanganiswa upise zvizere, zvichiwana chiyero chakanaka pakati pesimba rinobuda uye rekudzivirira kubuda kwemhepo. Kune mainjini ane masisitimu ekudzora mavharuvhu emagetsi, sensor yekumanikidza intake inogonawo kushanda senzira yekuchengetedza zviratidzo zvekutakura, ichibatsira kugadzirisa nguva yekuvhurwa kwevharuvhu intake uye kuwedzera kuvandudza mashandiro einjini.
Yambiro Yekukundikana: "Yambiro Yehutano" yeInjini
Kana sensor yekumanikidza inopinda ikakundikana, kushanda kweinjini kunokanganiswa, zvichikonzera zviratidzo zvakasiyana-siyana, zvichikonzera njodzi pakushanda kwemotokari uye kuchengetedzeka kwekutyaira.
Kukundikana kwe sensor yekuvhura uye yekumira kwesimba kunogona kukonzera kuti ECU isakwanise kuona vhoriyamu yekudya, zvichikonzera kusawirirana pakati pehuwandu hwemafuta anopinda nemafuta anopinda. Munguva yekuvhura injini ichitonhora, injini inogona kuda kuedza kakawanda kuti ibate moto zvinobudirira, uye zviratidzo zvinogona kuvandudzika zvishoma mushure mekudziya, asi inogona kuramba ichidzima injini mushure mekuivhura. Munguva yekumira kwesimba, kumhanya kweinjini kunochinja-chinja zvakanyanya pakati pe800-1000 rpm, zvichitoita kuti injini idengenyeke uye igare, zvakafanana nekukanganisa kwe cylinder, asi kutarisa ma spark plugs nema ignition coils kunoratidza mhedzisiro yakajairika, izvo zvinogona kunge zvichikonzerwa nekudonha kwechiratidzo^.
Kusawirirana kweSimba neKushandiswa kweFuel Munguva yekumhanyisa, kumhanya kweinjini kunowedzera asi kumhanya kwemotokari kunowedzera zvishoma nezvishoma, zvichipa "kunzwa sekunge hausisina giya", nemhinduro yesimba inononoka zvakanyanya. Kushanda kwesimba kwemamwe mamodheru e1.6L kunogona kutoipa kupfuura kwe1.0L. Izvi zvinodaro nekuti sensor haigoni kukurumidza kupindura shanduko mukumanikidzwa kweintake mushure mekunge throttle yavhurwa, uye kupinza kwemafuta kweECU kunononoka, zvichikonzera gap remagetsi. Panguva imwe chete, kukanganisa kunogona kukonzera ECU kusanzwisisa huwandu hweintake, zvichikonzera kusawirirana muhuwandu hwemusanganiswa, kungave kwakawanda zvichikonzera utsi hutema kubva papombi yekubuda nemoto uye kupisa kusina kukwana, kana kusasimba zvakanyanya zvichikonzera simba risina kukwana. Chero zvazvingava, kushandiswa kwemafuta kuchawedzera zvakanyanya, uye kushandiswa kwemafuta kwemamwe mota kunogona kutokwira kubva pa8L/100km kusvika pa12L/100km^.
Kuvhenekerwa kweChiedza Chekukanganisa uye Njodzi Dzinogona Kuitika Kana chiratidzo chesensor chikadarika chiyero, chiedza cheinjini (MIL) chiri padashboard chinovhenekerwa. Uchishandisa chishandiso chekuongorora cheOBD, makodhi akadai seP0105 (kukundikana kwesensa yedunhu) uye P0106 (chiratidzo chisina musoro) anogona kuverengwa. Inenge 60% yezvikanganiso zvinokonzerwa nekukuvara kwesensor, uye 40% inokonzerwa nematambudziko ewaya. Kusateerera zviratidzo izvi kunogona kutungamira kuzvikanganiso zvidiki zvichichinja kuita matambudziko makuru, uye muzviitiko zvakakomba, mota inogona kungoerekana yamira pakutyaira, kunyanya panguva yekudzikamisa mafambiro kana kuchinja giya, zvichikonzera njodzi huru dzekuchengetedza^.
Kutsvaga Kukanganisa: "Kurohwa" Kunokonzerwa Nezvinhu Zvakawanda
Kukundikana kwesensa yekumanikidza kwemuchina hakukonzerwi nechinhu chimwe chete asi kunokonzerwa nematambudziko akawanda akadai sesensa pachayo, waya, uye mapombi evacuum.
Kutyoka kwedunhu remukati kana kuti short circuit mu sensor zvinodzivirira chiratidzo chekumanikidzwa kuti chisashandurwe uye chitumirwe zvakanaka, sekuchekwa kwechiteshi muchiteshi chekutumira ruzivo, uye ECU haizogamuchire data rechokwadi^.
Zviratidzo zvinobuda zvisina kujairika zvikanganisowo zvakajairika. Kazhinji, chiratidzo chinofanira kuchinja zvine hungwaru ne intake manifold vacuum, uye kana chiratidzo "chikanonoka", ECU inogadzirisa injection yemafuta zvichibva paruzivo rusirirwo, zvichiita kuti mashandiro einjini asave asina kujairika^. Uyezve, kana vacuum hose inobatanidza intake pressure sensor ne intake pipe ikavharika kana kudonha, zvichadzivirira sensor kuti isanzwe pressure signal chaiyo, kungofanana ne "bridge" rinotyoka uye kutumirwa kwemashoko kuchikanganiswa.
Kuongorora Kwakarurama: Dzorera Kuona kweSensor
Pakugadzirisa dambudziko re intake pressure sensor, matanho anotevera anogona kutorwa kuti ugadzirise dambudziko nemazvo: Chekutanga, shandisa chishandiso chekuongorora kuti uverenge kodhi yekutadza uye kutanga waona kwakanangana nekutadza. Kana kodhi yekutadza ine chekuita ne sensor ikaratidzwa, tarisa kana vacuum hose yakavharika kana kuti iri kudonha, uye kana waya yacho yakakuvara kana kuti isina kubatana zvakanaka. Chechipiri, ita bvunzo yekushanda pa sensor, bvisa sensor plug, vhura ignition switch, uye yera voltage iri pakati peVCC terminal neE2 terminal iri pa plug. Kazhinji, inofanira kunge iri pakati pe4.5 ne5.5V. Kana voltage isiri yepamutemo, tarisa waya kubva kuECU kuenda ku sensor kana ku ECU pachayo. Chekupedzisira, shandisa nzira yekutsiva. Tsiva sensor inofungidzirwa kuti ine mhosva neyakajairika. Kana dambudziko rikanyangarika, zvinogona kusimbiswa kuti sensor yakakuvara.
Kunyangwe sensor yekumanikidza inopinda iri diki, yakakosha pakushanda zvakanaka kweinjini. Kunzwisisa mashandiro ayo, zviratidzo zvekukanganisa, uye nzira dzekuongorora zvinogona kubatsira varidzi vemotokari kuona matambudziko nenguva, kudzivirira zvikanganiso zvidiki zvinokonzera kurasikirwa kukuru uye kuchengetedza injini iri mumamiriro akanaka nguva dzese.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
