TPS - kuyini? Ukulungiswa of TPS. Mpintsha Isikhundla Inzwa

imoto yesimanje siqukethe sebuningini izingxenye nemikhulu. Futhi ngisho iphutha ezincane kunazo zonke kubo kungaholela emiphumeleni engathí sina kakhulu. Enye yalezi izingxenye incane mpintsha isikhundla inzwa (TPS). Hlobo luni ngokuningiliziwe futhi kanjani ukucacisa iphutha layo? Izimpendulo yonke le mibuzo kanye neminye imikhakha Uzofunda ngokuhamba sihloko lanamuhla.

isici isici

valve mpintsha - isakhi kwesakhiwo kohlelo edonsa uphethiloli injini. Inhloso Its main - ukuze ulungise inani le-air ngokufaka injini. Ngamanye amazwi, lesi sici ilawula kuhlangana emoyeni ngophethiloli ngezabelo ezithile. TPS isethwe Vaz nezinye izimoto eziningi ezifuywayo phakathi engayitholi ezininginingi futhi lemifanekiso air.

Ngu design, inzwa mpintsha - uhlobo air valve. Lapho ilungu lisasesimweni evulekile, ezingeni ingcindezi ohlelweni edonsa imoto ilingana umfutho womoya, futhi lapho ivaliwe, lesi silinganiso kuyehla kube isimo cleaner.

Inzwa mpintsha isikhundla kuhlanganisa olulodwa-phenduka unomphela futhi resistors onhlobonhlobo. Ukumelana Abo ingqikithi ohms mayelana 8. Ngesinye iziphetho kakhulu kwalesi sakhi we isilawuli sidla ireferensi voltage encane (esibulalayo yesibili ixhunywe "isisindo"). Kusuka lapha ngokusebenzisa Resistor kumlawuli iyisiginali isikhundla samanje mpintsha okwamanje. Ngokuvamile lokhu ishayela ne voltage kusuka 0.7 volts ukuba 4 kuye ngokuthi ezingeni element isikhundla.

zinhlobo

Kunezinhlobo ezimbili zama-TPS. Yiziphi lezi zinto? Lokhu kungaba yingxenye athutha noma kagesi enophephela. Eyokuqala ngokuvamile sisetshenziswa izimoto ephansi ekupheleni. Zonke izici zayo abamelwe ehlangana ku iyunithi ahlukene okuhlanganisa izinto ezifana nalezi:

1. Ezezindlu.
2. Valve mpintsha.
3. Inzwa.
4. IAC (control kokungenzi lutho isivinini).

umzimba umphini likhona uhlelo Ukupholisa wemoto. Nalapha futhi kukhona amapayipi ukuthi ahlinzeke umsebenzi wokutakula izinhlelo kaphethiloli intuthu futhi crankcase ukupholisa.

Umlawuli egcina idling yangaphakathi omlilo injini speed crankshaft lapho valve ivaliwe ngesikhathi kokuqala futhi iyazifudumeza injini noma lapho imishini elisizayo. IAC siqukethe stepper motor kanye valve. Lezi zingxenye ezimbili zilawulwa ukugeleza komoya yiwo ogelezela ohlelweni engayitholi e dlula damper.

Nokho, abakhiqizi imoto ezingasho Mans izimoto zabo valve drive kagesi kuleli eminyakeni embalwa edlule. izakhi ezinjalo siqu uhlelo electronic control yabo, iqinisekisa lemali elikhulu torque nhlobo amabanga ijubane futhi ukulayisha imoto. Lokhu kwandisa hhayi kuphela amandla okuhambisa, kodwa encishisiwe ukusetshenizwa kukawoyela nentuthu oyikhiphayo.

Umehluko damper kagesi

Ngikuphi okuhlukileko ngale ngxenye nozakwabo mechanical? umehluko zako ezisemqoka ezisetshenzisiwe ukuntuleka uxhumano mechanical phakathi namafutha isinyathelo futhi DMZ kanye nemithethonqubo XX yokuhamba valve uqobo.

Kodwa lokho akusona zonke izici zawo. Njengoba phakathi isinyathelo igesi kanye mpintsha alukho uxhumano eqinile uhlelo electronic kungaba uqobo nomthelela lemali torque yangaphakathi omlilo engine, ngisho noma umshayeli wemoto engakwazanga ukuyigwema ucindezela namafutha. Zonke lezi zinguquko zenzeka ngokusebenzisa izenzo izinzwa okokufaka, control unit kanye actuator.

Ngaphandle TPS, uhlelo electronic control ukhona namafutha isinyathelo isikhundla inzwa ukushintsha wazihlephula, bamba. Ngakho, i- control unit motor iphendula zimpawu kusuka izinzwa oguqula pulses idatha ku izenzo control phezu kwe-module valve.

Izici design module

Lo msuka kuhlanganisa izinto ezifana:

• Ezezindlu.
• I mpintsha.
• Motor.
• Reducer.
• Mpintsha Isikhundla Inzwa.
• Mshini ukubuya entwasahlobo.

Ngezinye izikhathi emotweni ngokushesha setha 2 TPS. Inikeza imoto? Ngomqondo onabile, noma yimaphi amandla awusebenzi engeza, kodwa umsebenzi Ungaqhubeka ngenkathi Neyesibili inzwa ehluleka. Ngakho, ukufakwa ezimbili TPS Kwenziwa ukuze siwethembe kakhudlwana wokusebenza module. Lezi zici zingaba-non-contact ngokuhambisa contact. Futhi ekuklanyweni module ine valve isikhundla eziphuthumayo. Isebenza sibonga indlela ukubuya entwasahlobo. Uma module wafika yisiphambeko, lishintsha kuyo yonke inhlangano yabantwana.

TPS: Fault

Njenganoma iyiphi enye into, lo mpintsha isikhundla inzwa unekhono ziwohloke. Kulokhu-ke kuyadingeka ukwazi izimpawu eziyisisekelo ukuwa kwakhe. Ngakho, yini TPS izimpawu ukuthi singase singaphumeleli?

Ngokuyinhloko kuwufanele ukunaka ekusebenzeni injini at lutho. Uma uphendulela "iflothi", mhlawumbe kubangelwa ukusebenza engafanele inzwa. Kuba yisikhathi futhi lapho uphawu yokwehluleka angase kokumisa injini lapho ocucuzayo okungazelelwe we isinyathelo igesi. Kakhulu kukhona ukwehluleka inzwa uma imoto kuyashesha. Kulokhu, ukwehluleka kungase kube ngesilinganiso isethi (umbono ukuthi injini uphethiloli enikeziwe). Ngezinye izikhathi, lapho eshayela ayikwazi basabela phezu isinyathelo igesi. Ngaphezu kwalokho, ijubane injini freeze ezingeni eziyizigidi ezingu-1.5-3, futhi angawi ngisho nalapho eyize yokudlulisela. Okungukuthi izimpawu ukungasebenzi lesi sici is ngqo exhumene nokuqhutshwa injini, futhi yimiphi ukusebenza kwawo ayilungile kungase kubonise inzwa noma valve eziyimbangela yezinkinga ezizuzwa. Uma uqaphela okungenani oyedwa uphawu ezinjalo, khona-ke udinga ukuhlola ukusebenza TPS. Vaz-2114 "Samara" nabalandeli bayo uxilongwe cishe ngokulinganayo. Ngakho-ke, imiyalelo esethwe ngezansi, kungasetshenziswa kuzo zonke izimoto yasekhaya (ngisho angaphandle) ukukhiqizwa.

Indlela hlola TPS ngokwakho?

Yenza uphethwe mpintsha isikhundla inzwa kungenzeka ngaphandle kosizo ochwepheshe izandla. Ozokudinga ithuluzi - kuba multimeter. Ngakho, vula ukuthungela futhi sibheke dashboard. Uma kungaqali isibani "Hlola Engin" phakamisa hood bese ubheka inzwa isikhundla.

Manje sithatha ngezandla multimeter futhi uhlole nokuba khona 'lokususa ". Ukuze wenze lokhu, cisha ukuthungela futhi uthole 'uquqaba' phakathi izintambo. Akunzima ukukwenza. Khona-ke aphinde vula ukuthungela futhi uthole ikhodi yamandla. Ngakho siyabona ukuthi amandla yanikezwa inzwa.

Yini okufanele uyenze ngokulandelayo?

Ngemva kwalokho, thina hlola kuvulwa oxhumana lamashumi amabili. Basuke esisogwini isixhumi inzwa ngenhla noma ngezansi. Ixhunyiwe kwi-oxhumana we izintambo phezu multimeter, kanti eyesibili izoya ichopho. Uma konke kuhamba kahle, voltage ngesikhathi ukunyakaza kancane ezingeni kudivayisi zizoshintsha kunani ebhethrini. Uma umcibisholo esikalini imitha uhlala endaweni, hlola ukusebenza kwe-Resistor variable, okuyinto ngaphakathi TPS. Kuyini lokhu isici nokuthi ukuxilonga ke? Lokhu Resistor kuyinto ingxenye inzwa isikhundla, eshintsha ukumelana layo kuye ezingeni isinyathelo isikhundla. Bese eqinisekisa it kanje. Ukuze uqale, bentambo asele unamathele multimeter, le ukuthungela esitshalweni, bese valve idluliswa kancane kakhulu. Kulokhu, udinga ukuqaphelisisa isimo umcibisholo esikalini wezinsimbi zomculo. Kufanele kube khona kuzuba. Uma kunjalo, cishe, injini efanele.

ukumiswa Ofanele ichopho imoto mpintsha

Kanjani i-self-ukuhlela TPS? Lo msebenzi akudingi amakhono akhethekile ulwazi, ngakho-ke ungakwazi ukubhekana ngisho imfundamakhwela umshayeli. Ukuze ulungise tube lukathayela kumele inqanyuliwe, okuyinto uqhuba emoyeni. Ngaphezu kwalokho, lesi sici is ngokucophelela bahlanza by kuphela ezinamandla. Lokhu kungase kube utshwala noma uphethiloli. Ukuze lula Kunconywa ukuhlanza ucezu lukathayela sendwangu. Kodwa hhayi kuphela wakhe ngayo uphethiloli. Ngaphezu kwalokho, ukuxhaphaza ezinjalo yenziwe ezininginingi isibalo sabahlengikazi abaqeqeshwayo futhi mpintsha uqobo. Emva kokuba engahashazanga kungxenye yokugcina, ahlole ngokucophelela isimo yayo kwesakhiwo.

ukumiswa Ofanele mpintsha isikhundla inzwa

Uma valve ayinakho umonakalo mechanical, uqhubekele inqubo ukulungiswa. Ukuze wenze lokhu, khulula yasibamba nezikulufi yayo, lift futhi uyayekela esithubeni nje. Lapha sidinga ukuzwa buhlungu ebusweni. Ngokulandelayo, ulungise isimo esishubile ngezikulufo kuze kube seqophelweni ize iphele "zakusyvanie" imininingwane. Ngemva kwalokho silungise nati imishudo athambise imishudo we inzwa. Khona-ke ngobumnene cranking umzimba wakhe bese usetha isikhundla salo ukuze voltage washintsha kuphela ngokuvula valve mpintsha. Ungakwazi bese ubuyela uvala imishudo bese uqale ukusebenza imoto. Njengoba ubona, ulungise inzwa mpintsha futhi isikhundla salo - lokhu akukona inqubo nzima, ukuze ubhekane okuyinto amandla cishe zonke umnikazi imoto. Kulokhu, lonke ukulungisa akwanele ukuchitha imizuzu engaphezu kuka 10-15 isikhathi khulula.

isiphetho

Ngakho, sathola ukuthi mpintsha ezinjalo, TPS nalokho izakhi it liqukethe. Ekugcineni kufanele kuphawulwe ukuthi singakanani entsha mpintsha isikhundla inzwa. Intengo ye-elementi zokhahlamba kusuka ruble 200 kuya ku-800. Bayidayise ezitolo, futhi izimakethe yezimoto.
