Throttle position sensorzvinhu zvakakosha muinjini dzemotokari dzemazuva ano, zvichipa ruzivo rwakakosha nezve throttle chinzvimbo kuEngine Control Unit (ECU).Throttle Position Sensors, Mabasa Avo, Mhando, Misimboti Yekushanda, Zvishandiso uye Matambudziko.TPS inoita basa rakakosha mukuchengetedza kuita kweinjini, optimize kushanda kwemafuta uye kuderedza kuburitsa.Sezvo tekinoroji yemotokari ichienderera mberi, TPS inoramba iri chinhu chakakosha mukutsvaga kwekuvandudza kuita kwemotokari uye kusimbaradza kwezvakatipoteredza.
Throttle Position Sensors (TPS) chikamu chakakosha chemagetsi emagetsi majekiseni masisitimu anoshandiswa mune akawanda emazuva ano emukati emoto injini.Iyo inotarisisa chinzvimbo cheiyo throttle plate uye inotaurira ruzivo urwu kune Injini Yekudzora Unit (ECU).Iyo ECU inoshandisa data yeTPS kuverenga iyo yakakodzera mhepo-mafuta musanganiswa, nguva yekubatidza uye mutoro weinjini, kuve nechokwadi chekushanda kwakanyanya kweinjini pasi pemamiriro akasiyana ekutyaira.Kune marudzi maviri makuru e-throttle position sensors: potentiometric uye isina-kubata.
Inogoneka TPS ine chinhu chinopikisa uye ruoko rwekupukuta rwakabatana kune throttle shaft, kana iyo throttle plate yakavhurwa kana kuvharwa, ruoko rwewiper runofamba pamwe nechinhu chinopikisa, kushandura kuramba uye kugadzira yakaenzana kune throttle chinzvimbo voltage chiratidzo.Iyi analog voltage inobva yatumirwa kuECU kuti igadziriswe.Isiri-inobata TPS, inozivikanwawo seHall Effect TPS, inoshandisa musimboti weHall Effect kuyera iyo throttle chinzvimbo.Iyo ine magineti yakasungirirwa kune iyo throttle shaft uye Hall effect sensor.
Sezvo magineti achitenderera neiyo throttle shaft, inogadzira magineti, inowonekwa neHall effect sensor, ichigadzira inobuda voltage chiratidzo.Kuenzaniswa ne potentiometric TPS, isiri-inobata TPS inopa kuvimbika kwepamusoro uye kusimba nekuti hapana ma mechanic parts akabatana zvakananga ne throttle shaft.Nheyo yekushanda yeTPS ndeyekushandura mechanical movement ye throttle valve mumagetsi emagetsi ayo magetsi ekugadzirisa unit anogona kuziva.
Sezvo iyo throttle plate inotenderera, ruoko rwe wiper pane potentiometer TPS inofamba ichitevedza nhanho yekupikisa, ichichinja kubuda kwevoltage, uye kana iyo throttle yakavharwa, kupikisa kuri pakakwirira, zvichikonzera chiratidzo chakaderera.Sezvo iyo throttle inovhura, kuramba kunodzikira, zvichiita kuti chiratidzo chevoltage chisimuke zvakaenzana.Iyo yemagetsi control unit inodudzira iyi voltage siginecha kuona throttle chinzvimbo uye kugadzirisa injini paramita zvinoenderana.Mune isingabatanidzi TPS, magineti anotenderera anogadzira shanduko yemagineti, inowonekwa neHall-effect sensor.
Izvi zvinogadzira inobuda voltage siginecha inoenderana neiyo throttle valve chinzvimbo, kana iyo throttle plate yakavhurwa, iyo magineti simba rinoonekwa nehoro effect sensor shanduko, yemagetsi control unit inobata chiratidzo ichi kudzora basa reinjini.Throttle position sensors inowanikwa mune dzakasiyana siyana dzemukati injini dzinopisa, dzinosanganisira mota, midhudhudhu, mabhoti, uye dzimwe mota.Izvo zvakakosha zvikamu zvemagetsi emagetsi jekiseni masisitimu uye emagetsi throttle control masisitimu, achigonesa kudzora chaiko kwekuita kweinjini uye kubuda.
Iko kusanganiswa kwema throttle position sensors kunounza akawanda mabhenefiti kune azvino mota masisitimu.Iyo throttle position sensor inogonesa iyo yemagetsi control unit kukwidziridza iyo air-mafuta musanganiswa uye ignition nguva yemhando dzakasiyana dzekutyaira nekupa chaiyo throttle chinzvimbo data, nekudaro zvinobudirira Kubatsira kuvandudza injini kushanda.Nekunyatso kudzora reshiyo yemafuta emhepo, TPS inobatsira kuvandudza kushanda kwemafuta, zvichikonzera kuderera kwemafuta uye kuburitsa.

Pamwoyo webasa rayo, throttle position sensor inoona nzvimbo ye throttle plate, iyo inovhura kana kuvhara apo mutyairi anodzvinyirira gasi pedal, kugadzirisa huwandu hwemhepo inopinda mukati mejini yakawanda.Iyo throttle position sensor yakaiswa pa throttle body kana yakasungirirwa kune iyo throttle shaft inoteedzera mafambiro eiyo throttle blade uye inoshandura iyo kune chiratidzo chemagetsi, kazhinji voltage kana kukosha kwekupokana.Ichi chiratidzo chinobva chatumirwa kuECU, iyo inoshandisa data kuita chaiyo-nguva kugadzirisa kune injini parameters.
Rimwe remabasa akakosha eTPS kubatsira ECU kuona mutoro weinjini.Nekubatanidza iyo throttle chinzvimbo nemamwe ejini paramita senge injini yekumhanyisa (RPM) uye kutora manifold pressure (MAP), iyo ECU inokwanisa kunyatso kuverenga mutoro uri painjini.Injini yekuremerwa data yakakosha pakuona iyo inodiwa jekiseni remafuta, nguva yekubatidza uye zvimwe zvine chekuita nekuita.Ruzivo urwu runogonesa iyo yemagetsi control unit kuti ikwidze iyo air-mafuta musanganiswa.
Mumotokari dzemazuvano dzakashongedzerwa neElectronic Throttle Control (ETC), TPS inobatsira kufambisa kutaurirana pakati pemutyairi accelerator pedal kupinza uye throttle kufamba kweinjini.Mune yakajairwa throttle system, iyo gasi pedal inosungirirwa nemagetsi kune gasi pedal netambo.Zvisinei, muETC system, throttle valve inotungamirirwa nemagetsi neECU maererano neTPS data.Iyi tekinoroji inopa kunyatsojeka uye kupindura, inosimudzira iyo yakazara kutyaira ruzivo uye kuchengetedzeka.
Chimwe chinhu chakakosha cheTPS ibasa rayo mukuongororwa kweinjini, iyo yemagetsi control unit inoramba ichitarisisa chiratidzo cheTPS uye ichichienzanisa nekumwe kuverenga sensor injini.Chero mutsauko kana kusanzwisisika mu data reTPS inokonzeresa kodhi yekuongorora dambudziko (DTC) uye inovhenekera "cheki injini" mwenje pane chiridzwa.Izvi zvinobatsira makanika kuona zvingangoitika zvine chekuita neiyo throttle system kana zvimwe zvikamu zveinjini kuitira kugadzirisa uye kugadzirisa nenguva.
