ukwehluleka kwenzwa ye-throttle

ukwehluleka kwenzwa ye-throttle kuholela ekusebenzeni okungazinzile kwenjini yomlilo yangaphakathi yemoto. Ukuthi i-TPS ayisebenzi ngendlela efanele ingaqondwa yizimpawu ezilandelayo: i-idle engazinzile, ukwehla kwamandla emoto, ukwanda kokusetshenziswa kukaphethiloli nezinye izinkinga ezifanayo. uphawu oluyisisekelo lokuthi inzwa ye-throttle position inephutha i-revving. Futhi isizathu esiyinhloko salokhu ukugqokwa kwamathrekhi okuxhumana we-throttle valve sensor. Nokho, kukhona ezinye eziningana.

Ukuhlola inzwa ye-throttle position kulula, futhi ngisho nomshayeli we-novice angakwenza. Okudingayo i-multimeter kagesi ekwazi ukukala i-DC voltage. Uma inzwa ihluleka, ngokuvamile akunakwenzeka ukuyilungisa, futhi le divayisi imane ithathelwe indawo entsha.

Izimpawu Zenzwa Yendawo Ephukile

Ngaphambi kokuqhubeka nencazelo yezimpawu zokuwohloka kwe-TPS, kufanelekile ukugxila kafushane embuzweni wokuthi inzwa ye-throttle position ithinta ini. udinga ukuqonda ukuthi umsebenzi oyisisekelo wale nzwa ukucacisa i-angle lapho i-damper iphendulwa khona. Isikhathi sokuthungela, ukusetshenziswa kukaphethiloli, amandla enjini evuthayo yangaphakathi, nezici eziguquguqukayo zemoto kuncike kulokhu. Ulwazi oluvela ku-sensor lungena ku-electronic control unit ICE, futhi ngesisekelo sayo ikhompuyutha ithumela imiyalo mayelana nenani likaphethiloli elinikeziwe, isikhathi sokuthungela, esinomthelela ekwakhekeni kwengxube ye-air-fuel efanele.

Ngakho-ke, ukuwohloka kwenzwa ye-throttle position kuvezwa ngezimpawu zangaphandle ezilandelayo:

• Okungazinzile, "okuntantayo", isivinini esingenzi lutho.
• Injini evuthayo yangaphakathi iyama ngesikhathi sokushintsha igiya, noma ngemva kokusuka kunoma yiliphi igiya iye esivinini esimaphakathi.
• Injini ingase ime ngokungahleliwe lapho ingenzi lutho.
• Ngenkathi ushayela, kukhona "amadiphu" nama-jerks, okungukuthi, ngesikhathi sokusheshisa.
• Amandla enjini yomlilo yangaphakathi ayancipha ngokuphawulekayo, izici ezishukumisayo zemoto ziyawa. Okuphawuleka kakhulu mayelana nokusheshisa amandla, izinkinga lapho ushayela imoto ukhuphuka, kanye / noma uma ilayishwe kakhulu noma idonsa inqola.
• Isibani sesexwayiso se-Check Engine kuphaneli yensimbi siyakhanya (iyakhanyisa). Lapho uskenela amaphutha kumemori ye-ECU, ithuluzi lokuxilonga libonisa iphutha elithi p0120 noma elinye elihlotshaniswa nenzwa ye-throttle position futhi liyayiphula.
• Kwezinye izimo, imoto iyasetshenziswa kakhulu.

Kuyafaneleka futhi ukuqaphela lapha ukuthi izimpawu ezibalwe ngenhla zingase futhi zibonise izinkinga nezinye izingxenye zenjini evuthayo yangaphakathi, okungukuthi, ukwehluleka kwe-valve ye-throttle. Kodwa-ke, ngesikhathi sokwenza ukuxilonga, kufanelekile ukuhlola inzwa ye-TPS.

Izizathu zokwehluleka kwe-TPS

Kunezinhlobo ezimbili zezinzwa ze-throttle position - ukuthintana (okungavimbeli ifilimu) kanye nokungathintani (i-magnetoresistive). Kaningi, izinzwa zokuxhumana ziyehluleka. Umsebenzi wabo usekelwe ekuhambeni kwesilayidi esikhethekile kumathrekhi aphikisayo. Ngokuhamba kwesikhathi, ziyaguga, yingakho inzwa iqala ukunikeza ulwazi olungalungile kukhompyutha. Ngakho, izizathu zokwehluleka kwenzwa ekwazi ukumelana nefilimu kungaba:

• Ukulahlekelwa kokuxhumana kusilayida. Lokhu kungabangelwa kokubili ukuguga nokudabuka kwayo ngokomzimba, noma ucezu lwethiphu. Isendlalelo esiphikisayo singase siguge, ngenxa yokuthi ukuxhumana kukagesi nakho kuyanyamalala.
• I-voltage yomugqa ekuphumeni kwenzwa ayikhuphuki. Lesi simo singabangelwa ukuthi ukumbozwa kwesisekelo kusulwe cishe kusisekelo endaweni lapho isilayidi siqala ukunyakaza.
• Ukugqokwa kwegiya lesilayidi.
• Ukuphuka kwezintambo zezinzwa. Kungaba kokubili izintambo zamandla nezisiginali.
• Ukwenzeka kwesekethe emfushane kumjikelezo kagesi kanye / noma wesignali wenzwa ye-throttle position.

Mayelana Izinzwa ze-magnetoresistive, ngakho-ke abanayo i-deposition evela kumathrekhi aphikisayo, ngakho-ke ukuhlukana kwayo kuncishiswa kakhulu ukuphuka kwezintambo noma ukuvela kwesifunda esifushane kumjikelezo wabo. Futhi izindlela zokuqinisekisa zohlobo olulodwa nolunye lwezinzwa ziyefana.

Noma ngabe kunjalo, ukulungisa inzwa ehlulekile akunakwenzeka, ngakho-ke ngemuva kokwenza ukuxilongwa, udinga nje ukuyifaka esikhundleni esisha. Kulokhu, kuyinto efiselekayo ukusebenzisa inzwa ye-throttle position non-contact, ngoba umhlangano onjalo unokuphila okude kakhulu kwenkonzo, nakuba kubiza kakhulu.

Ungayibona kanjani inzwa ye-throttle ephukile

Ukuhlola i-TPS ngokwayo kulula, futhi okudingayo i-multimeter kagesi ekwazi ukukala i-DC voltage. Ngakho-ke, ukuze uhlole ukuhlukaniswa kwe-TPS, udinga ukulandela i-algorithm engezansi:

• Vula umlilo wemoto.
• Nqamula i-chip koxhumana nabo benzwa futhi usebenzise i-multimeter ukuze wenze isiqiniseko sokuthi amandla ayeza inzwa. Uma amandla ekhona, qhubeka uhlole. Uma kungenjalo, udinga "ukukhipha" izintambo zokuhlinzeka ukuze uthole indawo yekhefu noma esinye isizathu sokuthi kungani i-voltage yenzwa ingafaneleki.
• Setha i-probe engalungile ye-multimeter phansi, kanye ne-probe enhle ekuthinteni okukhiphayo kwenzwa, okuvela kuyo ulwazi oluya kuyunithi yokulawula ye-elekthronikhi.
• Lapho i-damper ivaliwe (ihambisana ne-accelerator pedal ecindezelekile ngokugcwele), i-voltage ekuthinteni okukhiphayo kwenzwa akufanele idlule i-0,7 Volts. Uma uvula ngokugcwele i-damper (cindezela ngokuphelele i-accelerator pedal), khona-ke inani elihambisanayo kufanele libe okungenani ama-volts angu-4.
• khona-ke udinga ukuvula i-damper ngesandla (jikelezisa umkhakha) futhi ngokuhambisana uqaphe ukufundwa kwe-multimeter. Kufanele bavuke kancane. Uma inani elihambisanayo likhuphuka kungazelelwe, khona-ke lokhu kubonisa ukuthi kunezindawo eziphukile kumathrekhi aphikisayo, futhi inzwa enjalo kufanele ithathelwe indawo entsha.

Abanikazi be-VAZ yasekhaya bavame ukubhekana nenkinga yokuwohloka kwe-TPS ngenxa yekhwalithi embi yezintambo (okungukuthi, ukufakwa kwazo), ezihlomele lezi zimoto ezivela embonini. Ngakho-ke, kunconywa ukuthi esikhundleni sazo kube nezingcono, isibonelo, ezikhiqizwe yi-CJSC PES/SKK.

Futhi, kunjalo, udinga ukuhlola ngethuluzi lokuxilonga le-OBDII. Isithwebuli esidumile esisekela izimoto eziningi Skena Ithuluzi Pro Black Edition. Kuzokusiza ukuthi uthole ngokunembile inombolo yephutha futhi ubone imingcele ye-throttle, futhi unqume ukuthi imoto nayo inezinkinga, mhlawumbe kwezinye izinhlelo.

Amakhodi ephutha 2135 kanye no-0223

Iphutha elivame kakhulu elihlotshaniswa ne-throttle position sensor linekhodi P0120 futhi imele "ukuphuka kwenzwa / switch "A" throttle position / pedal". Elinye iphutha elingenzeka i-p2135 libizwa ngokuthi "Ukungafani ekufundweni kwezinzwa No. 1 no-No. 2 ye-throttle position." Amakhodi alandelayo angase futhi abonise ukusebenza okungalungile kwe-DZ noma inzwa yayo: P0120, P0122, P0123, P0220, P0223, P0222. Ngemva kokufaka inzwa entsha, kubalulekile ukusula imininingwane yephutha kumemori yekhompyutha.

Skena Ithuluzi Pro isebenza nezinhlelo zokuxilonga eziyinhloko ze-Windows, iOS kanye nezinhlelo ze-Android nge-Bluetooth noma i-Wi-Fi. I-adaptha enjalo yokuxilonga yaseKorea ene-32-bit v 1.5 chip, hhayi i-Chinese 8-bit eyodwa, ngeke futhi ivumele ukufunda nokusetha kabusha amaphutha kumemori yekhompyutha, kodwa futhi nokuqapha ukusebenza kwakho kokubili i-TPS nezinye izinzwa. ku-gearbox, ukudluliselwa noma izinhlelo ezisizayo i-ABS, ESP, njll.

Kuhlelo lokusebenza lokuxilonga, isithwebuli sizonikeza ithuba lokubona idatha evela kunzwa kumarobhothi esikhathi sangempela. Uma uhambisa i-damper, udinga ukubheka ukufundwa kwama-volts kanye nephesenti yokuvula kwayo. Uma i-damper isesimweni esihle, inzwa kufanele inikeze amanani abushelelezi (ngaphandle kokugxuma) ukusuka ku-03 kuya ku-4,7V noma 0 - 100% ngesidampa esivalwe ngokugcwele noma esivulekile. Kulula kakhulu ukubuka umsebenzi we-TPS ngesithombe sokuqhafaza. Ukucwiliswa okubukhali kuzobonisa ukuguga kwesendlalelo esiphikisayo kumathrekhi enzwa.

isiphetho

ukwehluleka kwenzwa ye-throttle position - ukwehluleka akubalulekile, kodwa kudinga ukuxilonga futhi kulungiswe ngokushesha ngangokunokwenzeka. Uma kungenjalo, injini yomlilo yangaphakathi izosebenza ngaphansi kwemithwalo ebalulekile, okuzoholela ekunciphiseni insiza yayo yonke. Ezikhathini eziningi, i-TPS ihluleka ngenxa nje yokuguga nokudabuka futhi ayikwazi ukubuyiselwa. Ngakho-ke, idinga nje ukushintshwa ngezwe elisha.
