Isivamvo sendawo ye-Throttlezizinto ezibalulekileyo kwiinjini zeemoto zala maxesha, zibonelela ngolwazi olubalulekileyo malunga nesikhundla somoya kwiYunithi yoLawulo lweeNjini (ECU).I-Throttle Position Sensors, Imisebenzi Yazo, Iintlobo, Imigaqo yokuSebenza, usetyenziso kunye nemingeni.I-TPS idlala indima ebalulekileyo ekugcineni ukusebenza kwe-injini, ukwandisa ukusebenza kakuhle kwamafutha kunye nokunciphisa ukukhutshwa.Njengoko iteknoloji yeemoto iqhubeka iqhubela phambili, i-TPS ihlala iyinto ephambili kwimfuno yokuphucula ukusebenza kweemoto kunye nokuzinza kokusingqongileyo.
I-Throttle Position Sensors (TPS) yinxalenye ebalulekileyo yeenkqubo zokutofa kwe-elektroniki ezisetyenziswa kwiinjini ezininzi zokutsha zangaphakathi.Ibeka iliso kwindawo ye-throttle plate kwaye inxibelelane ngolu lwazi kwi-Engine Control Unit (ECU).I-ECU isebenzisa idatha ye-TPS ukubala umxube ofanelekileyo we-air-fuel, ixesha lokutshisa kunye nomthwalo we-injini, ukuqinisekisa ukusebenza kakuhle kwe-injini phantsi kweemeko ezahlukeneyo zokuqhuba.Kukho iintlobo ezimbini eziphambili ze-throttle position sensors: i-potentiometric kunye ne-non-contact.
I-TPS enokwenzeka iqulethe into ephikisayo kunye nengalo yokucima edityaniswe kwi-throttle shaft, xa i-plate ye-throttle ivuliwe okanye ivaliwe, ingalo ye-wiper ihamba kunye ne-resissive element, iguqula ukuxhathisa kunye nokuvelisa ngokulinganayo kwi-voltage ye-throttle position.Lo mbane we-analog emva koko uthunyelwa kwi-ECU ukuze iqhutywe.I-TPS engaqhagamshelani nayo, eyaziwa ngokuba yi-Hall Effect TPS, isebenzisa umgaqo we-Holl Effect ukulinganisa indawo ye-throttle.Iqukethe imagnethi eqhotyoshelwe kwi-throttle shaft kunye ne-Hall effect sensor.
Njengoko imagnethi ijikeleza kunye ne-throttle shaft, ivelisa indawo yamagnetic, efunyenwe yi-Hall effect sensor, ivelisa isignali yombane ophumayo.Xa kuthelekiswa ne-TPS ye-potentiometric, i-TPS engadibananga inika ukuthembeka okuphezulu kunye nokuqina ngenxa yokuba akukho zixhobo zomatshini ezinxibelelana ngokuthe ngqo ne-throttle shaft.Umgaqo wokusebenza we-TPS kukuguqula ukunyakaza komatshini we-valve ye-throttle ibe ngumqondiso wombane onokuthi iyunithi yokulawula i-electronic ikwazi ukuyiqonda.
Njengoko ipleyiti ye-throttle ijikeleza, ingalo ye-wiper kwi-potentiometer ye-TPS ihamba kunye nomkhondo wokumelana, itshintsha i-voltage output, kwaye xa i-throttle ivaliwe, ukuchasana kuphezulu, kubangele umqondiso we-voltage ephantsi.Njengoko i-throttle ivula, ukuchasana kuyancipha, kubangela ukuba uphawu lombane lunyuke ngokulinganayo.Iyunithi yokulawula i-elektroniki itolika lo mqondiso we-voltage ukumisela indawo ye-throttle kunye nokulungelelanisa iiparamitha ze-injini ngokufanelekileyo.Kwi-TPS engadibananga, i-magnet ejikelezayo ivelisa indawo yamagnetic eguqukayo, efunyenwe yi-Hall-effect sensor.
Oku kuvelisa umqondiso ombane ophumayo ohambelana nesikhundla sevalve ye-throttle, xa ipleyiti ye-throttle ivuliwe, amandla ombane wemagnethi afunyenwe yi-hall effect sensor utshintsho, iyunithi yokulawula i-electronic iqhuba lo mqondiso ukulawula umsebenzi we-injini.Izinzwa zesikhundla seThrottle zifumaneka kwiinjini ezahlukeneyo zokutsha zangaphakathi, kubandakanya iimoto, izithuthuthu, izikhephe kunye nezinye iimoto.Zingamacandelo abalulekileyo kwiisistim ze-elektroniki zokutofa kwamafutha kunye neenkqubo zolawulo lwe-electronic throttle, ezivumela ulawulo oluchanekileyo lokusebenza kwe-injini kunye nokukhutshwa.
Ukudityaniswa kwe-throttle position sensors kuzisa izibonelelo ezininzi kwiinkqubo zeemoto zanamhlanje.I-sensor ye-throttle position yenza ukuba i-electronic control unit ikhulise umxube we-air-fuel kunye nexesha lokutshisa kwiimeko ezahlukeneyo zokuqhuba ngokubonelela ngedatha echanekileyo ye-throttle position, ngaloo ndlela ngokufanelekileyo Ukunceda ukuphucula ukusebenza kweenjini.Ngokulawula ngokuchanekileyo umlinganiselo we-air-fuel, i-TPS inceda ekuphuculeni ukusebenza kakuhle kwamafutha, okukhokelela ekusetyenzisweni okuphantsi kwamafutha kunye nokukhutshwa.
Umsebenzi ophambili
Kwintliziyo yomsebenzi wayo, i-throttle position sensor ibona indawo ye-throttle plate, evula okanye ivale xa umqhubi ecinezela i-pedal yegesi, elawula ubuninzi bomoya ongena kwi-injini yobuninzi.Inzwa ye-throttle position efakwe kumzimba we-throttle okanye ifakwe kwi-throttle shaft ilandelela ngokuchanekileyo ukuhamba kwe-throttle blade kwaye iyiguqulele kwisignali yombane, ngokuqhelekileyo i-voltage okanye ixabiso lokumelana.Lo mqondiso uthunyelwa kwi-ECU, esebenzisa idatha ukwenza uhlengahlengiso lwexesha langempela kwiiparamitha ze-injini.
Omnye wemisebenzi ephambili ye-TPS kukunceda i-ECU ibone umthwalo wenjini.Ngokudibanisa indawo ye-throttle kunye nezinye iiparitha ze-injini ezifana nesantya se-injini (RPM) kunye nokuthatha uxinzelelo oluninzi (MAP), i-ECU ingabala ngokuchanekileyo umthwalo kwi-injini.Idatha yomthwalo we-injini ibalulekile ekumiseleni ixesha lokutofa kwamafutha afunekayo, ixesha lokutshisa kunye neminye imiba enxulumene nokusebenza.Olu lwazi lwenza ukuba iyunithi yokulawula i-elektroniki isebenzise umxube wamafutha omoya.
Kwiimoto zanamhlanje ezixhotyiswe nge-Electronic Throttle Control (ETC), i-TPS inceda ukuququzelela unxibelelwano phakathi kwe-accelerator pedal input kunye ne-throttle movement ye-injini.Kwinkqubo ye-throttle eqhelekileyo, i-gas pedal ixhunywe ngomatshini kwi-pedal yegesi ngentambo.Nangona kunjalo, kwinkqubo ye-ETC, i-valve ye-throttle ilawulwa ngekhompyutha yi-ECU ngokwedatha ye-TPS.Le teknoloji ibonelela ngokuchaneka okukhulu kunye nokuphendula, ukunyusa amava okuqhuba kunye nokhuseleko jikelele.
Enye inkalo ebalulekileyo ye-TPS yindima yayo ekuxilongweni kwe-injini, iyunithi yokulawula i-electronic ibeka iliso ngokuqhubekayo uphawu lwe-TPS kwaye luyithelekise nolunye ufundo lwesivamvo se-injini.Nakuphi na ukungafani okanye ukungahambi kakuhle kwidatha ye-TPS kubangela ikhowudi yenkathazo yokuxilonga (DTC) kwaye ikhanyise "injini yokukhangela" ukukhanya kwipaneli yesixhobo.Oku kunceda oomatshini bachonge imiba enokubakho enxulumene nenkqubo ye-throttle okanye amanye amacandelo e-injini ukulungiselela ukugcinwa nokulungiswa kwangexesha.
