Umsebenzi wepulaki yokuthola izinga likawoyela emotweni
Ipulaki yokuthola izinga likawoyela emotweni iyisici esibalulekile sokuxhumanisa phakathi kwenzwa yezinga likawoyela kanye nohlelo lukagesi lwemoto. Umsebenzi wayo oyinhloko ukudlulisa ulwazi lwezinga likaphethiloli ethangini likaphethiloli, okuvumela ideshibhodi ukuthi ibonise inani likaphethiloli futhi mhlawumbe isekele eminye imisebenzi yohlelo lokuphatha imoto.
Umsebenzi Oyinhloko
Isignali yezinga likawoyela edluliswayo: Ipulaki ixhuma inzwa yezinga likawoyela (ngokuvamile uhlobo oluntantayo noma uhlobo lwe-capacitive), iguqula ushintsho lwenani likawoyela lube isignali kagesi, bese idluliselwa kuyunithi yokulawula injini (ECU) noma kudeshibhodi ukuze kufezwe ukuboniswa kwenani likaphethiloli.
Ukusekela ukuqapha kwamapharamitha amaningi (amamodeli athuthukile): Kuma-capacitive sensors afana nochungechunge lwe-CR-606, ipulaki ingadlulisa idatha ngasikhathi sinye njengokushisa kwethangi likaphethiloli, izinga lokushisa lefeni, ukusheshisa, indawo, kanye nebanga, okusetshenziselwa ukuhlolwa okuphelele kwesimo sempilo yemoto.
Ukuqala i-alamu yezinga eliphansi likawoyela: Uma inani likawoyela lingaphansi kwenani elibekiwe, ipulaki idlulisela isignali, isebenze isibani sesexwayiso sedeshibhodi ukuze ixwayise umshayeli ukuthi agcwalise uphethiloli ngesikhathi.
Incazelo Yesikhundla Seplagi
Indawo Evamile: Ngokuvamile itholakala phansi kwethangi likaphethiloli (ukuze kube lula ukuthintana ngqo nophethiloli) noma eduze kwepani likaphethiloli lenjini (kwamanye amamodeli ahlanganisa imisebenzi yokuqapha uwoyela).
Umehluko Wemodeli: Izindawo zokufaka ziyahlukahluka phakathi kwemikhiqizo ehlukene. Isibonelo, amanye amamodeli e-BMW afakelwe ekhanda lesilinda noma epanini likawoyela; kumamodeli e-Volkswagen afana ne-Jetta, ukwakheka okuthile kudinga ukuqinisekiswa ngokubheka incwadi yemiyalelo esemthethweni. Amanothi Okufanele Uwaqaphele
Ungazami ukusebenza ngaphandle kolwazi lochwepheshe: Ukuxhumana okuxegayo noma okungekuhle kwepulaki kungabangela ukuthi igeyiji kawoyela ingalungi. Kodwa-ke, ukuhlolwa noma ukulungiswa kufanele kwenziwe ochwepheshe ukuze bagweme ukulimaza inzwa noma ukubangela izingozi ohlelweni lukaphethiloli.
Hlukanisa esibonakalayo se-OBD: Ipulaki yokuthola izinga likawoyela iyisici soxhumano lwendawo senzwa, kuyilapho isibonisi sokuxilonga se-OBD (ngokuvamile esitholakala ngaphansi kwekhabhini lomshayeli) sisetshenziselwa amadivayisi angaphandle ukufunda amakhodi amaphutha kanye nedatha yesikhathi sangempela yemoto yonke. Imisebenzi yawo ihlukile.
Amaphutha epulaki yokuthola izinga likawoyela emotweni avame ukubonakala njengokubonisa okungavamile kugeji kawoyela (njengokunganyakazi, ukushintshashintsha phezulu naphansi, ukusetha kabusha ngokuzumayo kube yi-zero, njll.). Angabangelwa yizizathu ezilandelayo:
Izimbangela ezivamile kanye nezixazululo
Isignali ye-voltage engavamile yesekethe ye-plug
Ipulaki yesenzwa yezinga likawoyela ngokuvamile inezintambo ezintathu, ezihlinzeka ngo-12V, 14V kanye nomhlabathi (0V). Uma kukhona i-voltage engavamile, izobangela ukudluliswa kwesignali okungalungile. Ungasebenzisa i-multimeter ukuhlola ukuthi ama-voltage ephini ngalinye ajwayelekile yini.
Ukuxhumana okuxekethile noma okungekuhle kwepulaki
Ukudlidliza kwemoto kungabangela ukuthi ipulaki ikhululeke noma ama-terminal axoveke, okuholela ekuphazamisekeni kwesignali ngezikhathi ezithile (ngezikhathi ezithile). Hlola ukuthi ipulaki ixhunywe kahle yini bese uhlanza izingxenye ezixovekile.
Umonakalo ku-sensor uqobo
I-resistor yangaphakathi eguquguqukayo noma i-float yesensa yezinga likawoyela ingase yonakale, okubangela izimpawu ezifanayo nephutha le-plug. Uma i-voltage ijwayelekile kodwa i-oyela gauge isalokhu ingajwayelekile, kungadingeka ukuthi kushintshwe isensa.
Ikhodi yephutha engamanga ebikwe yisofthiwe yesistimu
Amanye amamodeli angase abike ngamanga amakhodi amaphutha ngenxa yezinkinga zesofthiwe ye-ECU. Okwamanje, ungasula amakhodi amaphutha usebenzisa ithuluzi lokubhala ikhodi bese ucabanga ukuthuthukisa uhlelo lwemoto.
Izinyathelo zokuxazulula izinkinga eziphakanyisiwe
Hlola uxhumano lwepulagi: Qinisekisa ukuthi ipulagi ixhunywe kahle yini, uma kukhona ukusha, ukugqwala noma ukuxega.
Linganisa i-voltage: Sebenzisa i-multimeter ukukala ama-voltage angu-12V, 14V kanye nomhlabathi wama-terminal e-plug ukuze uhlole ukuthi ajwayelekile yini.
Qaphela ukunyakaza kokuntanta: Engeza inani elincane likaphethiloli bese uqaphela ukuthi igeyiji kawoyela iyaphendula yini; uma inkomba ingahambi ngemva kokugcwalisa ithangi, kungenzeka ukuthi ukuntanta kuvinjiwe (into evamile, izolulama ngemva kokusetshenziswa kukaphethiloli).
Funda ikhodi yephutha: Sebenzisa ithuluzi lokubhala ikhodi le-OBD ukuze ufunde ikhodi yephutha ethile ukuze unqume ukuthi ingabe inkinga yenzwa, izintambo noma i-ECU.
Ukulungisa kochwepheshe: Uma ungakwazi ukukuxazulula wedwa, kunconywa ukuthi uye esitolo se-4S noma esitolo sokulungisa sochwepheshe ukuze ugweme ukwahlulela kabi kanye nezingozi zokuphepha ezingaba khona.
Qaphela: Kwamanye amamodeli (njenge-Audi A6L), lapho inzwa yezinga likawoyela ihluleka, kungase kube nokungakwazi ukuqala imoto ngenxa yokuthi i-ECU ibona umfutho kawoyela ongajwayelekile futhi ibangele indlela yokuvikela.
Uma uhlangabezana nesimo esinjalo, sicela ubeke phambili ukuhlola inzwa yezinga likawoyela kanye nohlelo lukaphethiloli.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
