TPS - yintoni na? Ukulungiswa TPS. Umcephe wokunyusa Isikhundla woluvo

imoto Modern siqulathe ezininzi amacandelo kunye neendibano. Kwaye nkqu nandzu zincinane kubo kungakhokelela nemiphumela emibi kakhulu. Enye yezi macandelo lincinane sensor umcephe isikhundla (TPS). Loluphi uhlobo iinkcukacha nendlela ukumisela ityala layo? Iimpendulo yonke le mibuzo kunye ezininzi ziya kufunda ngethuba nqaku yanamhlanje.

element uphawu

umphini umcephe - icandelo noshowo kwinkqubo ezityiwa injini zepetroli. injongo yawo - ukunyenyisa inani womoya nghena injini. Ngamanye amazwi, le element elawula indlela elisetyenziswa ngayo emoyeni ipetroli enkulu ezithile. TPS umiselwe Vaz kunye nezinye iimoto ezininzi zasekhaya phakathi ukusebenzisa ubuninzi kunye filter emoyeni.

Xa uyilo, umenzi woluvo umcephe - uhlobo umphini lomoya. Xa ilungu ngokwaseburhulumenteni evulekileyo, inqanaba lamandla lendlela ukuthathwa isithuthi ilingana womoya, kwaye xa ivaliwe, eli xabiso kuyehla kube karhulumente cleaner.

Le woluvo umcephe Indawo luquka omnye-turn abasisigxina kunye resistors variable. besenza ukuya kutsho kwitotali engu malunga 8 ohms. Kwenye izigqibo kakhulu yale elementi umlawuli ondliwa ombane encinane reference (i-terminal yesibini liqhagamshelene "ubunzima"). Ukusuka apha ngokusebenzisa resistor ukuya umlawuli na umqondiso yemeko yangoku ukunyathela umcephe wokunyusa ngalo mzuzu. Amaxesha amaninzi lo sazi kunye ombane ukusuka kwi 0.7 volts ku-4 kuxhomekeke kwizinga element sikhundla.

uhlobo

Kukho iindidi ezimbini TPS. Ziziphi ezi zinto? Oku kuba yinxalenye eqhutywa ngumatshini okanye kagesi. Eyokuqala isoloko isetyenziswa iimoto ekupheleni ephantsi-. Zonke izinto enqila ziye zadityaniswa iyunithi eyahlukileyo kuquka izinto ezifana:

1. Izindlu.
2. Ukunyathela umcephe wokunyusa vana.
3. Woluvo.
4. IAC (ulawulo isantya bengasebenzi).

umzimba ivelufa ifakwe kwi injini isithuthi ngayo. Apha kakhulu kukho imibhobho ezibonelela iinkqubo recovery umsebenzi komsi ipetroli crankcase umoya.

Umlawuli ugcina i iduma lwangaphakathi ukutshiswa injini isantya crankshaft xa vana ivaliwe ngexesha zokuqala ukuzifudumeza injini okanye xa izixhobo abangabancedani. IAC ibandakanya stepper ngeemoto vana. Ezi ndawo zimbini balawulwa ukuhamba komoya ujikeleze kwinkqubo ukutya kwi esa umatshini.

Nakuba kunjalo, abenzi ngakumbi nangakumbi imoto Mans iimoto zabo mbobo kunye drive yombane kwiminyaka embalwa edlulileyo. izinto ezinjalo kufuneka lwemfundo yabo elektroniki yolawulo, eqinisekisa imali ngokupheleleyo torque kuwo onke amabanga isantya kwaye ukulayisha imoto. Oku akunyusi nje kuphela amandla kunye namandla, kodwa amafutha sinciphile ezikhutshwayo.

Ukungaboni osisidambisi electric

Yintoni na eyahlukileyo ngale inxalenye oogxa babo mechanical? Umahluko omkhulu awo ukungabikho uqhagamshelwano ngoomatshini phakathi namafutha ezinyovwayo kunye ukulwa ngokunjalo ekumiseleni XX ngokushukumisa ivalve ngokwayo.

Kodwa ke zonke iimpawu zayo. Njengoko phakathi emoto kunye umcephe akukho uxhulumaniso engqongqo, inkqubo yekhompyutha ngokwayo nefuthe isixa torque injini yokuvutha kwangaphakathi, kwanokuba umqhubi cofa kwi namafutha. Zonke ezi nguqu zenzeke izenzo boluvo igalelo, iyunithi yolawulo kunye actuator.

Ngaphandle TPS, inkqubo yolawulo ngekhompyutha ikhona isivamvo indawo namafutha ezinyovwayo kwaye uyicima waqhekeza kunye iklatshi. Ngaloo ndlela, iyunithi yolawulo motor iphendula imiyalezo evela nabenzi boluvo kwaye iguqula pulses data kwiintshukumo kolawulo kwi module vana.

Iimpawu ze-design umnqongo

Le element kuquka izinto ezifana:

• Izindlu.
• Ukunyathela umcephe wokunyusa.
• Motor.
• Reducer.
• Umcephe wokunyusa Position woluvo.
• Isixhobo ukubuya spring.

Ngamanye amaxesha le moto nangoko elibekwe 2 TPS. Inika imoto? Enyanisweni, naliphi na igunya ayithethi ukongeza, kodwa umsebenzi kuqhubeka ngexesha elinye isivamvo yesibini lutshitshe. Ngenxa yoko, ukufakelwa ezimbini TPS lwenziwa ukuze kuphuculwe ukuthembeka ukusebenza umnqongo. Ezi zinto zingaba non-contact kunye contact sliding. Kwakhona kuyilo kwimodyuli une kwivelufa kwindawo likaxakeka. Isebenza ngenxa indlela ukubuya emthonjeni. Ukuba umnqongo weza sisiphoso esithile, litshintsha ibandla lonke.

TPS: Icala

Njengaye nawuphi na umba, woluvo indawo umcephe uyakwazi ukubola. Kule meko kuyimfuneko ukwazi iimpawu ezingundoqo yokuwa yakhe. Ngoko ke, yintoni na imiqondiso TPS ukungaphumeleli?

Kuqala kubalulekile ukunikela ingqalelo ukusebenza injini e bengasebenzi. Ukuba kuvela "edadayo", mhlawumbi oko kubangelwa ukusebenza ngokungafanelekanga wexesha elongezelelweyo lomenzi woluvo. Kwakhona iliphawu yokusilela baso banokubekwa ukuyeka injini xa ubhobhozayo ngesiquphe le emoto. kakhulu kukho ukusilela woluvo xa isithuthi uqhu-. Kulo mzekelo, ukusilela abe ngeqondo iseti (nomfuziselo wokuba injini ipetroli kunikwa). Ngamanye amaxesha, ngoxa uqhuba imoto akakwazi kusabela kwi emoto. Ukongeza, isantya injini freeze kwinqanaba 1.5-3 million, kwaye kuwa xa bengasebenzi transmission. Okt iimpawu ukungasebenzi lwesi sakhi kunxulumene ngqo nokusebenza injini, kunye nayiphi na umsebenzi wayo ezingachanekanga ukuze abonise zincwadi Womenzi okanye isivalo kakuhle. Ukuba ubona ubuncinane omnye onjalo induna, ngoko ufuna ukukhangela ukusebenza TPS. Vaz-2114 "Samara" kunye nabo balandelayo kuyo abafunyenwe phantse ngokulinganayo. Ngoko ke, imiyalelo echazwe apha ngezantsi, ukuze zisetyenziswe kuzo zonke iimoto ekhaya (kwaye amazwe) kwimveliso.

Indlela ukukhangela TPS ngokwakho?

Yenza isifo umcephe isivamvo ujongise kunokwenzeka ngaphandle koncedo ziingcali izandla. Konke uya kufuneka isixhobo - yinto multimeter. Ngoko ke, vula i ucinezelo kwaye ujonge kwidashboard. Ukuba ayiwenzi ibhalbhu kukhanya "Khangela Engin" Phakamisa ukwesona uze ukhangele woluvo sikhundla.

Ngoku thatha wezandla multimeter kwaye khangela ubukho "thabatha". Ukwenza oku, cima ucinezelo kwaye ufumane i "izihlwele" phakathi kwala macingo. Kunzima musa. Babuya ngoko ke vula ucinezelo kwaye ufumane intambo yombane. Ngoko siyabona ukuba amandla nakwesiphi woluvo.

Ntoni okulandelayo?

Emva koko, siya khangela ukuvulwa abafowunelwa yamashumi amabini. Bona zibekwe kwi Isidibanisi woluvo ngasentla okanye ngezantsi. Uxokonyezelelwe abafowunelwa phakathi kwale micwe phezu multimeter, kwaye eyesibini ukususa caba. Ukuba yonke into kakuhle, lo ombane kule intshukumo incinane kwinqanaba ifowuni iya kutshintsha kwixabiso phaya kwibhetri. Ukuba itolo kwisikali imitha kuhlala endaweni, khangela ukusebenza resistor bume, leyo ngaphakathi TPS. Yintoni na le ngxenye nendlela basibone ngayo? Le resistor isisahlulo woluvo indawo, nto leyo etshintsha ukuxhathisa yayo ngokuxhomekeke kwinqanaba namafutha sikhundla. Kwaye eqinisekisa oko ngolu hlobo lulandelayo. Okokuqala, ucingo eseleyo iqhotyoshelwe multimeter, lo ucinezelo ivuliwe, kwaye ngoko ke ivelufa kumphatha ngokucothayo kakhulu. Kulo mzekelo, kufuneka ukuba baqwalasele ngenyameko imeko itolo kwisikali sixhobo. Kufuneka kungabikho ukweqa. Ukuba kunjalo, mhlawumbi, injini kakuhle.

olufanelekileyo lwesimo le caba imoto umcephe wokunyusa

wenza njani self-hlengiso TPS? Lo msebenzi ayifuni izakhono ezizodwa kunye nolwazi, ngoko ke ngisho umqhubi abo basandula kuqalisa. Ukulungisa ityhubhu incence kufuneka awucimeki, nto leyo eqhuba umoya. Ngaphezu koko, le element uhlanjiweyo ngononophelo kuphela esinamandla. Oku kube utywala okanye ipetroli. Kuba kulula kucetyiswa ukucoca iqhekeza incence ngelaphu. Kodwa nje kuphela yakhe ukubamba ipetroli. Ngaphezu koko, loo ukuxhaphaza wenziwa ngezifo esingena kunye umcephe ngokwayo. Emva kokuba ihlanjwe loo nto yokugqibela, ahlole ngenyameko imeko yayo noshowo.

olufanelekileyo lwesimo woluvo isikhundla umcephe wokunyusa

Ukuba ivelufa akukho monakalo ngomatshini, dlulela inkqubo hlengiso. Ukuze wenze oku, ndiwuthukulule eqwalasele ngezikhonkwane zayo, phakamisa ulundulule ngephanyazo. Apha kufuneka ukuba ukuva ngesibetho ebusweni. Okulandelayo, ukunyenyisa ukuqina izikrufu kwinqanaba de iyalahleka "zakusyvanie" iinkcukacha. Emva koko ukulungisa iimbumbulu kunye nezitshixo azikhulule Imivalo woluvo. Ngoko kuhle cranking umzimba wakhe waza wammisa indawo yayo ukuze ombane batshintshwa kuphela emva kokuvulwa ivelufa umcephe wokunyusa. Unako ke ukubuyela uvala nezitshixo ukuqala umsebenzi besithuthi. Njengoko ubona, ulungise woluvo umcephe yaye indawo yayo - le yinkqubo enzima, ukumelana apho amandla phantse yonke umnini imoto. Kulo mzekelo, lo wokulungisa yonke akwanelanga ukuba bachithe imizuzu ngaphezu 10-15 ixesha free.

isiphelo

Ngoko ke, safumanisa ukuba umcephe enjalo, TPS yaye yintoni imiba liphethe. Okokugqibela ke, kufanele kuphawulwe ukuba yimalini woluvo omtsha position umcephe wokunyusa. Ixabiso le element isusela ukusuka engange-200 ukuya 800. It kuthengiswa ezivenkileni, kwaye iimarike ngomatshini.
