Basa re sensor yekumanikidza yekudya kwemotokari
Monitor intake manifold pressure
Chinongedzo chekumanikidza kweinjini chakabatana nechinhu chinopinza mweya kuburikidza nechubhu chevacuum kuti chione shanduko chaiyo yekumanikidza muchinhu chinopinza mweya chiri kuseri kwevharuvhu yethrottle panguva chaiyo. Kuchinja uku kwekumanikidza kwakabatana zvakanyanya nekumhanya uye mutoro weinjini, uye masensa anoshandura shanduko idzi dzemuchina kuita masaini emagetsi anotumirwa kuECU.
Gadzirisa injection yemafuta
Zvichibva pachiratidzo chekumanikidzwa chinopihwa nesensor, ECU inoverenga nemazvo huwandu hwemafuta anodiwa neinjini. Kana mutoro weinjini ukawedzera, kumanikidzwa kweinjini kunoderera, chiratidzo chekubuda kwesensor chinowedzera, uye ECU inowedzera huwandu hweinjini injection zvinoenderana. Zvikasadaro, zvinodzikira. Kugadziriswa uku kunovimbisa kushanda zvakanaka kweinjini mumamiriro akasiyana ekushanda.
Nguva yekudzora kupisa
Chinoongorora kumanikidzwa kweinjini chinobatsirawo ECU kugadzirisa nguva yekupisa. Kana mutoro weinjini wawedzera, Angle yekupisa inononoka zvakakodzera. Kana mutoro waderedzwa, Angle yekupisa inofambira mberi. Kugadzirisa uku kunobatsira kuvandudza mashandiro einjini uye kuchengetedza mafuta.
Kuverenga kwemhepo inobatsira
MuType D fuel injection system, intake pressure sensor inoshandiswa pamwe chete ne air flow meter kuyera intake volume zvisina kunanga, nokudaro kuverenga intake flow nemazvo. Basa iri rekushandira pamwe rinowedzera kunatsiridza intake fuel uye mashandiro einjini.
Kuona nekudzivirira zvikanganiso
Chinoongorora kumanikidzwa kweinjini chinokwanisa kuona shanduko dzisina kujairika muinjini, dzakadai sekuvharika kana kubuda kwemvura, uye kutumira masaini kuECU. Izvi zvinobatsira kuona kutadza kweinjini nenguva uye kutora matanho ekudzivirira kudzivirira kukuvara kwakawanda.
Mhando uye misimboti yekushanda
Ma sensor ekumanikidza anowanzo shandiswa anosanganisira varistor ne capacitive types. Varistor sensor inochinja resistance kuburikidza ne deformation ye silicon diaphragm uye inoburitsa chiratidzo chemagetsi. Capacitive sensor inoshandura capacitance value kuburikidza ne deformation ye diaphragm uye inoburitsa chiratidzo che pulse. Masensa ese ari maviri anoshandiswa zvakanyanya mumotokari dzemazuva ano nekuda kwe high qualitative uye nekukurumidza kupindura.
Muchidimbu
Chinongedzo chekumanikidza kweinjini yemotokari ndechimwe chezvinhu zvikuru zvehurongwa hwekudzora injini yemotokari, basa rayo haringogumiri pakutarisa kumanikidzwa chete, asiwo rinobatanidzwa mukupinza mafuta, nguva yekupisa, kuverenga kuyerera kwemhepo uye kuona zvikanganiso. Nekudzora ma parameter aya nemazvo, masensa anovandudza mashandiro einjini zvakanyanya, kuchengetedza mafuta uye utsi.
Sensor yekumanikidza intake yemotokari (sensor yekumanikidza intake) ndeimwe yezvinhu zvakakosha zvesystem yekuisa mafuta, kutadza kwayo kuchaita kuti injini ikwanise kugadzirisa chiyero chemhepo-mafuta nemazvo. Izvi ndizvo zviratidzo zvikuru uye zvikonzero zvekutadza:
Kuratidzwa kwechiratidzo chikuru
Kuoma kana kusakwanisa kutanga injini
Zviratidzo zve sensor zvisina kujairika zvichaita kuti ECU itadze kuverenga huwandu hwakakodzera hwemafuta anoshandiswa, zvichikanganisa zvakananga kupinza kwemoto uye kupinza mafuta.
Kana tambo ye sensor yakatyoka kana kuti yakapfupikiswa, ECU inogona kurasikirwa zvachose nedata rekumanikidzwa kwekudya, zvichikonzera kutadza kushanda kwe startup.
Kubuda kwesimba zvisina kujairika
Kukurumidza kusina kunaka kana kudzikira kwesimba: sensor haigone kugadzirisa chiratidzo nekuchinja kwedhigirii re vacuum, uye ECU inoverenga zvisizvo mweya unopinda, zvichikonzera kutsauka kwehuwandu hwemajekiseni emafuta.
kumhanya kusina kugadzikana: Kana musanganiswa wacho wakanyanya kukobvu kana kuti wakatetepa, injini inogona kusvetuka kana kushanduka-shanduka kwemota.
kusagadzikana kwekupisa
Utsi hutema hunobva papombi yekubuda utsi: musanganiswa wacho wakakora zvakanyanya zvekuti haugone kutsva zvakakwana, zvinowanzoonekwa nekumhanya nekukurumidza.
Kupisa pombi yekupinda: Kana musanganiswa wacho wanyanya kutetepa, gasi risina kupiswa rinobatidzwa mupombi yekupinda.
Kurongwa kwezvikonzero zvemhosva
Iyo sensor pachayo
Kukundikana kwechiyero chemukati che strain kana kutadza kwedunhu (semuenzaniso kutadza kwechiyero che semiconductor strain).
Voltage yechiratidzo chekubuda inodarika huwandu hwakajairika (sekunge voltage drift).
kutadza kwekunze kwakabatana
Hosipu ye vacuum yakavharika kana kuti iri kubuda mvura, izvo zvinokanganisa kufambiswa kwesimba.
Kusaiswa zvakanaka kwerin'i yechisimbiso kunotungamira pakuvharika kwenzvimbo inopinzwa pressure (signal mutation panguva yekumanikidzwa).
Mazano ekuongorora chirwere
Ongororo yekutanga
Tarisa kana rambi remagetsi rakabatidzwa (mamwe mamodheru achatanga OBD fault code).
Tarisa kubatana kwepombi ye vacuum uye sensor wiring harness.
Kuongororwa kwehunyanzvi
Shandisa diagnostics kuti uverenge data renguva chaiyo uye uenzanise pressure values dzakajairika.
Edza kana voltage yekubuda kwesensor ichisiyana zvichienderana nekuvhurwa kwethrottle.
Zano: Kana zviratidzo zviri pamusoro apa zvichiperekedzwa nemakodhi ekutadza (akadai seP0105/P0106), sensor nemasekete ane chekuita nazvo zvinofanirwa kutanga zvatariswa. Kuregeredzwa kwenguva refu kunogona kukonzera kukuvara kwe three-way catalytic converter kana kuwedzera kukuru kwekushandiswa kwemafuta.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
