Chii chinonzi sensor yekumanikidza yemotokari yakasiyana?
Sensor yekudzvanya yakasiyana-siyana chinhu chemagetsi chinoshandiswa kuyera musiyano wekudzvanya pakati penzvimbo mbiri dzakasiyana. Ndiyo imwe yenzvimbo dzakakosha dzekunzwa mumotokari dzemazuva ano. Haiyere kudzvanya kwakakwana asi inotarisa pakuona musiyano wekudzvanya (ΔP = P1 - P2) pakati penzvimbo mbiri dzakadai se "chiteshi chekupinda nechiteshi chekubuda" kana "kumusoro nekudzika", uye inoshandura musiyano uyu wekudzvanya kuita chiratidzo chemagetsi, icho chinozotumirwa kuyuniti yekudzora injini (ECU) kana mamwe masisitimu ekudzora ari mubhodhi kuti awane mutemo chaiwo wekushanda.
Maitiro Ekushanda Nekushandisa
Sensor yekudzvanya yakasiyana-siyana inoita basa re "pressure nerve" mumasisitimu akawanda akakosha emota. Mashandisirwo ayo makuru anosanganisira:
Kudzora kuburitswa kwemhepo inobuda mumhepo (DPF regeneration control): Iri ndiro rimwe remabasa ayo makuru. Sensor iyi inoiswa kumberi nekumashure kwefirita yezvikamu (DPF), ichitarisa musiyano wekumanikidzwa kwemhepo inobuda mumhepo. Kana carbon deposits ikakonzera musiyano wekumanikidzwa kupfuura mwero, ECU inotanga "chirongwa chekugadzirisazve mhepo", ichiwedzera tembiricha yekuburitsa mhepo kuti ibvise carbon deposits kudzivirira kuvharika, kurasikirwa nemagetsi, uye kuburitswa kwemhepo.
Kugadzirisa huwandu hweinjini intake uye air-fuel ratio: Mune mamwe masisitimu, inoshandiswa kuyera musiyano wekumanikidzwa pakati pe intake manifold iri kuseri kwethrottle nemhepo kana mapaipi chaiwo. Pamwe chete nedzimwe data dzesensor, inoverenga zvisina kunanga huwandu hweintake, ichibatsira ECU kudzora vhoriyamu yekuisa mafuta uye nguva yekupisa, zvichivandudza kushanda zvakanaka kwemoto.
Kutarisa sisitimu yemafuta: Mumainjini edhiziri emagetsi ane simba guru kana masisitimu ekuisa peturu zvakananga, inotarisa musiyano wekumanikidzwa panzvimbo dzakasiyana dzepombi yemafuta, ichipa mhinduro yechikamu che millisecond kuECU, ichiwana kudzora kwakaringana kwehuwandu hwekuisa mafuta (nekukanganisa kuri mukati me ±0.02ml), ichienzanisa simba uye kuchengetedza mafuta.
Sisitimu yeEGR: Yakaiswa pamagumo evharuvhu yeEGR kana kuti EGR cooler, inoyera musiyano wekumanikidzwa kuti ione kuvhurwa chaiko kwevharuvhu yeEGR, kungave pombi yakavharika kana kuti iri kudonha, ichivimbisa vhoriyamu chaiyo yeEGR gas recirculation uye ichideredza zvinobudirira nitrogen oxide emissions.
Sisitimu yekudzora kubuda kwemafuta (EVAP): Inoshandiswa kuona kana paine kubuda kwemvura kana kuvharika mumapaipi emafuta. Sisitimu iyi inogadzira musiyano mudiki wekumanikidzwa, uye sensor inoona shanduko. Kana ikasasangana nezvaitarisirwa, sisitimu iyi inoonekwa seine chikanganiso uye mwenje wechikanganiso unovhenekerwa.
Sisitimu yemhepo inomiswa: Mumhando dzemhando yepamusoro, inotarisa musiyano wekumanikidzwa pakati pemativi maviri echitubu chemhepo, ichishandira pamwe nekombuta iri mubhodhi kugadzirisa damping masekondi mashoma ega ega, zvichivandudza zvakanyanya kugadzikana kwemotokari mumigwagwa ine makomba.
Tsananguro Pfupi yeSimboti Yekushanda
Pakati pesensa yekudzvanya kwedhiragiramu idiaphragm inonzwira inokamura sensor kuita magumo ane kumanikidzwa kwakanyanya (H) uye magumo ane kumanikidzwa kwakaderera (L). Kana kumanikidzwa kwakayerwa P1 neP2 zvikashandiswa kumativi ese, diaphragm inoshanduka zvishoma nekuda kwekusiyana kwekumanikidzwa. Kushanduka uku kunoonekwa uye kunoshandurwa ne internal conversion mechanism (yakadai sekuchinja kwe resistance mu strain gauges, shanduko mu capacitance value, kana piezoelectric effect) kuita chiratidzo chemagetsi, icho chinowedzerwa uye chinodzoserwa necircuit, uye chobva chabuda se standard voltage, current, kana digital signal kuti ECU ishandise.
Mhedzisiro Yezvikanganiso
Kana sensor yekumanikidza yakasiyana-siyana yakakuvara kana kuti chiratidzo chisina kururama, ECU ichagamuchira data remusiyano wekumanikidza zvisirizvo, izvo zvinogona kutungamira ku:
Chiedza chemotokari chinovheneka
Torque yeinjini yakaganhurirwa, simba rinoderera
Kuverengwa kwehuwandu hwemafuta anoshandiswa mumafuta hakusi kwechokwadi, zvichikonzera kuwedzera kwekushandiswa kwemafuta, kushomeka kwesimba, kana kubuda kwemhepo.
Chirongwa chekuvandudza DPF hachina kujairika, chinogona kukonzera kuvharika kwakanyanya
Sisitimu yeEGR inoshanda zvisina kujairika, ichikanganisa kugadzikana kwemhepo inobuda uye kupisa
Mukupedzisa, kunyangwe sensor yekudzvanya yedhizaini iri diki, chinhu chakakosha chinoita kuti mota dzishande zvakanaka, dzitevedzere zvinodiwa pakuburitsa utsi, uye dzichengetedzeke.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
