Umsebenzi wenzwa yokucindezela uwoyela wezimoto
Umsebenzi oyinhloko wesenzwa yokucindezela uwoyela wemoto ukuthola ingcindezi kawoyela nokukhipha i-alamu lapho ingcindezi inganele . Inzwa yokucindezela uwoyela ifakwa epayipini elikhulu likawoyela lenjini, ithola ingcindezi kawoyela ngedivayisi yokulinganisa ingcindezi, bese iguqula lezi zimpawu zokucindezela zibe izimpawu zikagesi, ezidluliselwa kwisekethe yokucubungula isignali. Lapho ingcindezi kawoyela yehla ngaphansi kwenani eliphephile elisethwe kusengaphambili, isibani senkomba kawoyela kudeshibhodi sizokhanya ukuze sazise umshayeli ukuthi .
Isimiso sokusebenza
Kukhona ukumelana okushelelayo ngaphakathi kwenzwa yokucindezela uwoyela, futhi ushintsho lokucindezela uwoyela luzocindezela i-potentiometer yokumelana nokushelelayo ukuthi ihambe, bese ishintsha ugesi wegeyiji yokucindezela uwoyela, ukuze indawo yesikhombisi ishintshe. Ngesikhathi esifanayo, isignali idluliselwa enkombeni yokucindezela uwoyela ngomugqa wesignali, futhi isilinganiso sogesi esidluliswa amakhoyili amabili kusikhombisi siyashintshwa, ngaleyo ndlela sibonisa umfutho kawoyela wemoto yokuqala . Inzwa ivame ukwakhiwa yi-chip yenzwa yokucindezela ifilimu ebanzi, isekethe yokucubungula isignali, i-housing, idivayisi yebhodi yesekethe ehleliwe kanye nama-lead amabili. Isekethe yokucubungula isignali ihlanganisa isekethe yokunikeza ugesi, isekethe yokunciphisa inzwa, isekethe ye-zeroing, isekethe yokukhulisa i-voltage, isekethe yokukhulisa ugesi, isekethe yokuhlunga kanye nesekethe ye-alamu .
Indawo yokufaka
Inzwa yokucindezela uwoyela ngokuvamile ifakwe epayipini elikhulu likawoyela lenjini, futhi ngezinye izikhathi esihlalweni sesihlungi samafutha. Inzwa yakhiwe ngokuthintana, isipilingi, i-diaphragm kanye ne-diaphragm. Uma kungekho ngcindezi kawoyela, isipilingi sisunduza i-diaphragm ukuze ivale ukuthintana; Uma ingcindezi ifinyelela inani elibekiwe, i-diaphragm inqoba amandla esipilingi futhi iphule ukuthintana .
Izimpawu zokwehluleka kwenzwa yokucindezela uwoyela wezimoto zifaka phakathi izici ezilandelayo:
: Uma inzwa yokucindezela uwoyela yonakele, inkomba yokucindezela uwoyela izoqhubeka nokukhanya, kungakhathaliseki ukuthi ingcindezi yawoyela ingakanani, okungase kudukise umshayeli ukuba akholelwe ukuthi ingcindezi yawoyela wenjini ayijwayelekile.
Ukuqina: Ukukhanya kwesibani sokwehluleka kwenjini (okwaziwa nangokuthi i-MIL noma isibani sokuhlola injini) ngokuvamile kusho ukuthi iphutha litholakale ohlelweni lokulawula lwe-elekthronikhi lwemoto. Ukwehluleka kwenzwa yokucindezela uwoyela nakho kungenye yezizathu zokukhanya.
Isibonisi senani lokucindezela uwoyela elingajwayelekile : Esimweni sokusebenza kwemoto, uma inzwa yokucindezela uwoyela yehluleka, inani lokucindezela uwoyela eliboniswe kudeshibhodi lingase lingavamile, njengalelo eliboniswa njalo njengenani eliqinile (njenge-0.99) noma ububanzi bokuguquguquka okungajwayelekile.
Ikhodi yephutha i-P01CA iyavela: Lapho uhlelo lokuxilonga imoto luthola ukuthi i-voltage yesensa yengcindezi kawoyela ingaphezu kobubanzi obujwayelekile, ikhodi yephutha ehambisanayo, njenge-P01CA, izoqoshwa futhi iboniswe. Le khodi yenkinga ikhombisa ngqo inkinga yesensa yengcindezi kawoyela.
Izimbangela zokwehluleka kwenzwa yokucindezela uwoyela zingafaka:
Inzwa ngokwayo ayikhwalithi ephansi: amaphutha okukhiqiza noma ukuguga kuholela ekutholakaleni okungalungile noma okonakele.
Izinkinga zomugqa: Isekethe emfushane, isekethe evulekile noma ukuxhumana okungekuhle kungathinta ukudluliswa kwesignali.
Ukucindezela kukawoyela okungajwayelekile: ukucindezela kukawoyela okuphezulu kakhulu noma okuphansi kakhulu kuzoletha ukucindezela okukhulu ku-sensor.
Ukungcola kodaka: Udaka oluvela ngaphakathi kwenjini lungavimba noma lungcolise izinzwa.
Indawo yokufaka engalungile : ukuphambuka kwendawo yokufaka kuzothinta ukunemba kokutholwa kwenzwa.
ezinye izingxenye zokungasebenzi kahle kwenjini: njengokuvaleka kwesihlungi, uwoyela onganele, njll.
Ukungazinzi kwamandla kagesi: ukushintshashintsha kwamandla kagesi kuzophazamisa ukusebenza okuvamile kwenzwa.
I-internal short circuit ebangelwa ukungena kwe-sensor ku-liquid noma ku-oyela.
Izindlela zokuthola nokwelapha:
Sebenzisa ithuluzi lokuxilonga : funda ikhodi yephutha ngokuxhuma isikhombikubona sokuxilonga se-OBDII, isib. P0520 (iphutha lesekethe yenzwa yokucindezela uwoyela).
Hlola ukuxhumeka kwekhebula nenzwa: qiniseka ukuthi ukuxhumeka kwekhebula akugqwalile, akuphukile, noma akukhululekile.
Ukulinganisa i-voltage yokuphuma kwenzwa: Sebenzisa i-multimeter ukukala i-voltage yokuphuma kwenzwa futhi uqinisekise ukuthi ikhipha i-voltage efanele ngaphansi kwezingcindezi ezahlukene.
Ukuhlolwa kokuqhathanisa i-mechanical pressure gauge : Susa i-electronic oil pressure sensor bese ufaka i-mechanical pressure gauge ukuze kuhlolwe ukuqhathanisa ukuze kutholakale ukuthi i-sensor ayisebenzi yini.
Shintsha inzwa: Uma inzwa iqinisekisiwe ukuthi ayisebenzi, yishintshe ngenzwa entsha efanela imoto yokuqala.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
