Kodi sensor ya TPS ndi chiyani?

Throttle position sensorndi zigawo zofunika kwambiri zamainjini amakono zamagalimoto, zomwe zimapereka chidziwitso chofunikira chokhudza malo achitetezo ku Engine Control Unit (ECU).Masensa a Throttle Position, Ntchito Zawo, Mitundu, Mfundo Zogwirira Ntchito, Ntchito ndi Zovuta.TPS imagwira ntchito yofunikira pakusunga magwiridwe antchito a injini, kukhathamiritsa mafuta abwino komanso kuchepetsa kutulutsa mpweya.Pomwe ukadaulo wamagalimoto ukupitilirabe patsogolo, TPS ikadali chinthu chofunikira kwambiri pakufuna kukonza magwiridwe antchito amagalimoto komanso kukhazikika kwa chilengedwe.

Ma Throttle Position Sensors (TPS) ndi gawo lofunikira pamakina amagetsi amagetsi omwe amagwiritsidwa ntchito mumainjini amakono oyatsira mkati.Imayang'anira malo a throttle plate ndikudziwitsanso izi ku Engine Control Unit (ECU).ECU imagwiritsa ntchito deta ya TPS kuti iwerengere kusakaniza koyenera kwa mafuta a mpweya, nthawi yoyatsira ndi kuchuluka kwa injini, kuonetsetsa kuti injini ikuyenda bwino pamayendedwe osiyanasiyana.Pali mitundu iwiri ikuluikulu ya ma throttle position sensors: potentiometric ndi osalumikizana.

TPS yothekera imakhala ndi chinthu chotsutsa komanso mkono wopukutira wolumikizidwa ndi throttle shaft, pomwe mbale ya throttle ikatsegulidwa kapena kutsekedwa, mkono wa wiper umayenda motsatira chinthu chotsutsa, kusintha kukana ndi kupanga molingana ndi chizindikiro chamagetsi.Magetsi a analogiwa amatumizidwa ku ECU kuti akakonze.TPS yosalumikizana, yomwe imadziwikanso kuti Hall Effect TPS, imagwiritsa ntchito mfundo ya Hall Effect kuti iyeze malo omwe akugwedezeka.Zimapangidwa ndi maginito omwe amamangiriridwa ku throttle shaft ndi Hall effect sensor.

Pamene maginito amazungulira ndi throttle shaft, imapanga mphamvu ya maginito, yomwe imadziwika ndi Hall effect sensor, imapanga chizindikiro chamagetsi.Poyerekeza ndi potentiometric TPS, TPS yosalumikizana imapereka kudalirika kwakukulu komanso kukhazikika chifukwa palibe zida zamakina zomwe zimalumikizana mwachindunji ndi throttle shaft.Mfundo yogwira ntchito ya TPS ndikusintha kayendedwe ka makina a valve throttle kukhala chizindikiro chamagetsi chomwe chipangizo chowongolera zamagetsi chikhoza kuzindikira.

Pamene mbale ya throttle ikuzungulira, dzanja la wiper pa potentiometer TPS limayenda motsatira njira yotsutsa, kusintha mphamvu yamagetsi, ndipo pamene phokoso latsekedwa, kukana kumakhala kokwanira, zomwe zimapangitsa kuti pakhale chizindikiro chochepa.Pamene throttle imatsegulidwa, kukana kumachepa, zomwe zimapangitsa kuti magetsi azitha kukwera molingana.Chigawo chowongolera zamagetsi chimatanthauzira siginecha yamagetsi iyi kuti idziwe malo opumira ndikusintha magawo a injini molingana.Mu TPS yosalumikizana, maginito ozungulira amatulutsa kusintha kwa maginito, komwe kumadziwika ndi sensa ya Hall-effect.

Izi zimapanga chizindikiro chamagetsi chofanana ndi malo a throttle valve, pamene mbale ya throttle imatsegulidwa, mphamvu ya maginito yomwe imazindikiridwa ndi kusintha kwa sensa ya holo, gawo lamagetsi lamagetsi limayendetsa chizindikiro ichi kuti chiwongolere ntchito ya injini.Masensa a Throttle position amapezeka mumainjini osiyanasiyana oyatsira mkati, kuphatikiza magalimoto, njinga zamoto, mabwato, ndi magalimoto ena.Ndizinthu zofunika kwambiri pamakina ojambulira mafuta amagetsi ndi makina owongolera ma throttle amagetsi, zomwe zimathandizira kuwongolera bwino magwiridwe antchito a injini ndi mpweya.

Kuphatikiza kwa ma throttle position sensors kumabweretsa zabwino zambiri pamakina amakono amagalimoto.The throttle position sensor imathandizira gawo lowongolera zamagetsi kukhathamiritsa kusakaniza kwamafuta a mpweya ndi nthawi yoyatsira pamikhalidwe yosiyanasiyana yoyendetsa popereka chidziwitso cholondola cha throttle position, potero mothandiza Kuthandizira kukonza magwiridwe antchito a injini.Mwa kuwongolera ndendende kuchuluka kwamafuta amafuta, TPS imathandizira kuwongolera mafuta, zomwe zimapangitsa kuti mafuta asamawonongeke komanso kutulutsa mpweya.

Ntchito yaikulu

Pamtima pa ntchito yake, throttle position sensor imazindikira malo a throttle plate, yomwe imatsegula kapena kutseka pamene dalaivala akukhumudwitsa gasi, ndikuwongolera kuchuluka kwa mpweya wolowa mu injini.Sensa ya throttle position yomwe imayikidwa pa thupi la throttle kapena yomangiriridwa ku throttle shaft imayang'anitsitsa kayendedwe ka throttle blade ndikuisintha kukhala chizindikiro chamagetsi, nthawi zambiri voteji kapena mtengo wokana.Chizindikirochi chimatumizidwa ku ECU, yomwe imagwiritsa ntchito deta kuti ipange zosintha zenizeni za injini.

Chimodzi mwazofunikira za TPS ndikuthandiza ECU kudziwa kuchuluka kwa injini.Mwa kugwirizanitsa malo a throttle ndi magawo ena a injini monga liwiro la injini (RPM) ndi kuthamanga kwa manifold (MAP), ECU ikhoza kuwerengera molondola katundu pa injini.Deta ya kuchuluka kwa injini ndiyofunikira kuti mudziwe kutalika kwa jekeseni wamafuta, nthawi yoyatsira ndi zina zokhudzana ndi magwiridwe antchito.Chidziwitso ichi chimathandizira gawo lowongolera zamagetsi kuti likwaniritse kusakaniza kwamafuta a mpweya.

M'magalimoto amakono okhala ndi Electronic Throttle Control (ETC), TPS imathandizira kulumikizana pakati pa cholowetsa chowongolera chowongolera ndi kusuntha kwa injini.M'njira yodziwika bwino, chopondapo cha gasi chimalumikizidwa mwamakina ndi chopondapo cha gasi ndi chingwe.Komabe, mu dongosolo la ETC, valve yotsekemera imayendetsedwa pakompyuta ndi ECU malinga ndi deta ya TPS.Ukadaulo uwu umapereka kulondola kwambiri komanso kuyankha, kukulitsa luso loyendetsa bwino komanso chitetezo.

Mbali ina yofunika ya TPS ndi udindo wake mu diagnostics injini, pakompyuta control unit mosalekeza amayang'anira TPS siginecha ndikuyerekeza ndi ena injini sensa kuwerenga.Kusagwirizana kulikonse kapena kusokonekera mu data ya TPS kumayambitsa nambala yamavuto (DTC) ndikuwunikira "check engine" pagawo la zida.Izi zimathandiza zimango kuzindikira zovuta zomwe zingachitike zokhudzana ndi throttle system kapena zida zina za injini kuti akonze ndi kukonza munthawi yake.
