I-Camshaft position sensor - uyini umsebenzi wayo emotweni? Ungahlola kanjani inzwa ye-camshaft? Yazi izimpawu zokwaliwa
Okuqukethwe
Uyini umsebenzi wenzwa yendawo ye-camshaft?
Ukuhlaziya ukwakheka kwezimoto zesimanje, inzwa ye-camshaft enembile ingenye yezinto ezibaluleke kakhulu zokulinganisa ozozithola emotweni yakho. Inzwa yesikhathi enediski yokulinganisa ku-flywheel yeyunithi yamandla. Ivamise ukucwiliswa noma ifakwe amagiya noma ozibuthe. Inquma indawo yamanje ye-crank assembly futhi inquma ukuthi ipiston yesilinda sokuqala isendaweni eyaziwa ngokuthi yi-blind spot. Ngakho-ke, ikuvumela ukuthi unqume ngokunembile ukuqala kwenqubo yomjovo olandelanayo.
Umsebenzi wenzwa ye-camshaft esebenzayo futhi ukukhiqiza isignali evumela ukuthi ulawule i-valve ye-solenoid, okuyingxenye yezinhlelo zokujova eziqukethe ama-unit injection. Ngesikhathi esifanayo, ilawula ukusebenza kwenjini, ivimbela ukuvutha kokuxhumana kumasilinda. Isebenzisa umphumela weHholo ngokufunda izilinganiso egiyeni leringi. Inzwa yesikhathi iyisici esithinta ukusebenza kahle kwenjini. Ngenxa yalesi sizathu, kufanele kuqashelwe ukuthi ngezikhathi ezithile kuhlolwe ukufaneleka kwama-voltages adluliselwa yibo ku-diagnostician.
Ungahlola kanjani ukusebenza kwenzwa ye-camshaft?
Uma ufuna ukuhlola ukuthi inzwa yendawo ye-camshaft isebenza kanjani futhi uma amasignali ewakhiphayo elungile, kufanele ube namathuluzi amaningana onawo. Okokuqala, uzodinga i-ohmmeter ukukala ukumelana nogesi. Ngayo, ungabheka ukumelana phakathi komhlaba namatheminali esignali yesici sokulinganisa. Ngokuvamile i-multimeter elula ayanele futhi i-oscilloscope iyadingeka. Lokhu kuzokuvumela ukuthi ubone ukuma kwe-pulse ethunyelwe ingxenye.
Ikhono lokuxilonga likuvumela futhi ukuthi uhlole amandla kagesi phakathi kweyunithi yokulawula injini kanye nenzwa yendawo ye-camshaft. I-voltmeter kufanele ibonise i-5 V. Inani eliqondile kufanele linikezwe umenzi wemoto. Ukuzikala kudinga imishini ekhethekile. Uma ungenayo i-multimeter echwepheshile noma i-oscilloscope, sebenzisa izinsiza ze-diagnostician. Uchwepheshe uzokusiza uqiniseke ukuthi ukufundwa kulungile.
Yiziphi izimpawu zenzwa yendawo ye-camshaft eyonakele?
Enye yezinto ezibalulekile ezilawula ukusebenza kweyunithi yokushayela yemoto yabagibeli inzwa ye-camshaft position. Izimpawu zokusebenza kwayo okungalungile yizi:
- ukungakwazi ukuqala injini ngokujwayelekile;
- ukusayinda iphutha lesistimu ngesibani sokulawula;
- ukurekhoda ikhodi yephutha kumemori yekhompyutha esebhodini;
- ukusebenza kwesilawuli semoto kwimodi ephuthumayo.
Izimpawu zenzwa ye-camshaft embi akufanele neze zithathwe kancane. Nokho, ezinye zazo azikwazi ukutholwa ngokuzimela ngaphandle kwemishini ekhethekile. Yingakho ukuvakashela njalo umakhenikha kanye nokuhlolwa kobuchwepheshe bokuxilonga kubaluleke kakhulu.
Khumbula ukuthi inzwa yendawo ye-camshaft eyonakele ayinikezi ngaso sonke isikhathi izimpawu ezizwakalayo lapho ushayela. Ngesikhathi esifanayo, izinkinga zokuqalisa injini ngeke zihlotshaniswe njalo nokulimala kwayo komshini. Kungase kuvele ukuthi ingqikithi yokungasebenzi kahle ilele kumasekethe amafushane kumahhanisi ezintambo kanye nezimpawu ezingalungile kukhompyutha esebhodini. Enye inkinga evamile ukuphazamiseka kokuxhumana phakathi kwesici sokulinganisa kanye nesistimu yokulawula.
Iyini imiphumela yokusebenzisa imoto enenzwa yokuma ye-camshaft eyonakele?
Inzwa ye-camshaft ye-CMP engalungile ingabangela izinkinga eziningi ngenkathi ushayela. Ngaphezu kwalokho, ukunqotshwa kwayo ngokuvamile akubonakali izimpawu eziphawulekayo. Nokho, kunomthelela ekunciphiseni ukusebenza kwemoto, i.e. ukusheshisa okubuthakathaka namandla ancishisiwe. Injini ingase ime kungazelelwe ngesikhathi sokusebenza. Amaphutha ekusebenzeni kwawo angaphinde abe nomthelela ekwenyukeni okukhulu kokusetshenziswa kukaphethiloli kanye nokuvinjwa kokudlulisa. Isibonakaliso singase sinyakaze.
Ibiza malini inzwa yokuma ye-camshaft entsha?
Intengo yokuthenga yenzwa entsha yesikhundla se-camshaft imvamisa iphakathi kwama-euro angama-50 nama-50. Kuya ekwenziweni kanye nemodeli yemoto. Kufanele futhi ucabangele izindleko ezingase zibe khona zezinsizakalo zokulungisa ukuze umiselele ingxenye. Ingahluka kusuka kuma-euro ayi-100 kuye kwangama-40. Kungenzeka futhi ukuzihlanganisa ngokwakho le ngxenye. Amakhono afanele wezandla, imibhalo yobuchwepheshe bemoto namathuluzi akhethekile ayadingeka.
