Umsebenzi we-automobile camshaft phase sensor control valve
Indima eyinhloko ye-valve yokulawula inzwa yesigaba se-camshaft ukulawula ukungena nokugudluzwa kwenjini, ngaleyo ndlela kuthuthukiswe ukusebenza kwenjini nokonga kukaphethiloli. Ngokuqondile, i-valve yokulawula ithinta isikhathi sokuvula nokuvala kwe-valve ngokushintsha i-Angle yesigaba se-camshaft, okubuye kuthinte umthamo wokungenisa kanye nokukhipha injini. Lo mthethonqubo ungasiza injini ukuthi ifinyelele ukusebenza kahle kakhulu komlilo kanye nomnotho ngaphansi kwezimo ezihlukene zokusebenza.
Isimiso sokusebenza
Ama-valve okulawula inzwa yesigaba se-Camshaft ngokuvamile asebenza nezilawuli zesigaba se-camshaft. Lapho inzwa ibona isimo sokusebenza kwenjini, isignali idluliselwa ku-ECU (iyunithi yokulawula i-elekthronikhi), futhi i-ECU ilungisa isikhundla se-valve yokulawula ngokwalezi zimpawu, ngaleyo ndlela iguqule i-Angle yesigaba se-camshaft. Le nqubo yenziwa ngokusebenzisa amanzi noma ngogesi, okungase kwehluke kuye ngemodeli nomklamo.
Umthelela wephutha
Uma i-valve yokulawula inzwa yesigaba se-camshaft yehluleka, ingase iholele ekuncipheni kokusebenza kwenjini, ukwanda kokusetshenziswa kukaphethiloli, kanye nokukhishwa kwesisi esibi kakhulu. Isibonelo, uma i-valve yokulawula ingalungisi i-engeli yesigaba ngendlela efanele, ingase ibangele isikhathi esinganembile se-valve, sithinte ukusebenza kahle komlilo, okuholela ekubeni amandla angaphansi kanye nokwenyuka kokusetshenziswa kukaphethiloli.
Isiphakamiso sesondlo
Ukuze uqinisekise ukusebenza okuvamile kwe-valve yokulawula inzwa yesigaba se-camshaft, kunconywa ukuhlola nokugcina izingxenye ezifanele njalo. Lokhu kuhlanganisa ukuhlola izinga likawoyela wesistimu ye-hydraulic, ukuhlanza noma ukufaka esikhundleni sezihlungi ezivalekile, nokuhlola njalo ukuxhunywa kukagesi. Ngaphezu kwalokho, gwema ukugijima imoto isikhathi eside ezindaweni ezinokhahlo ukuze unciphise umonakalo ku-valve yokulawula.
Izimpawu zokwehluleka kwe-automotive camshaft phase sensor control valve zifaka ikakhulukazi:
Ubunzima noma ukungakwazi ukuqalisa : I-ECU ayikwazi ukuthola isignali yendawo ye-camshaft, okuholela ekudidekeni kwesikhathi sokuthungela, futhi injini kunzima ukuyiqalisa.
i-jitter yenjini noma ukwehla kwamandla : iphutha lesikhathi sokuthungela eliholela ekushiseni okunganele, injini ingase idlikize ngezikhathi ezithile, isheshise kancane.
ukwanda kokusetshenziswa kukaphethiloli, ukukhishwa kwesisi esiba kubi kakhulu : I-ECU ingase ingene "kwimodi yesimo esiphuthumayo", isebenzisa imingcele yomjovo engaguquki, okuholela ekuwongeni uphethiloli okungekuhle kanye nokukhipha umoya omningi ngokweqile.
Isibani esinephutha sivuliwe : i-on-board diagnostic system (OBD) ithola isignali yenzwa engavamile bese icupha ikhodi yephutha (isb. P0340) .
Ukuma noma ukungenzi lutho okungazinzile : Uma isignali yenzwa iphazamiseka, i-ECU ingase ingakwazi ukugcina isivinini esivamile sokungenzi lutho, okuholela ekumeni kwenjini kungazelelwe.
Ukukhipha amandla alinganiselwe : Amanye amamodeli akhawulela amandla enjini ukuze avikele isistimu.
Izizathu zokwehluleka zingabandakanya:
Inzwa ngokwayo ilimele : ukuguga kwezingxenye ze-elekthronikhi zangaphakathi, ukwehluleka kwezingxenye zokungeniswa kazibuthe, isifunda esifushane noma isekethe evulekile.
Ukwehluleka kwesekethe noma ipulaki : ipulaki ifakwe i-oxidized noma iyaxega, ihhanisi liyaguga, lifushane noma liphukile (isb. ukushisa noma amagundane) .
Ukungcola kwenzwa noma ukungena kukawoyela : udaka noma udoti wensimbi unamathiselwe endaweni yenzwa, okuthinta ukuqoqwa kwesignali.
inkinga yokufaka : ukucaciswa okungafanele kwenzwa (isibonelo, ibanga phakathi kwenzwa negiya le-camshaft likude kakhulu), ukuxega kwezikulufu zokulungisa .
Okunye ukwehluleka okuhlobene : ibhande lesikhathi/ukungalungi kahle kweketango, ukwehluleka kwenzwa yendawo ye-crankshaft, ukwehluleka kwe-ECU, noma ukuphazamiseka kukazibuthe.
Izindlela zokuhlola nokulungisa zihlanganisa:
Funda ikhodi yephutha : Sebenzisa ithuluzi lokuxilonga le-OBD ukuze ufunde ikhodi yephutha (njenge-P0340) futhi uqinisekise ukuthi ingabe iphutha lenzwa ye-camshaft.
Bheka izintambo zenzwa kanye nepulaki : hlola ukuthi ipulaki ivulekile, igqwalile, izintambo zocingo azonakalanga, zilungiswa noma zishintshe uma kunesidingo.
Inzwa ehlanzekile : Susa inzwa futhi ukhiphe uwoyela ongaphezulu noma udoti ngesicoci se-carburetor (ukunakekela ukugwema ukulimala ngokomzimba) .
Linganisa ukumelana nenzwa noma isignali : Sebenzisa i-multimeter ukuze uhlole ukuthi ingabe ukumelana kwenzwa kuyahlangabezana yini nezinga lemanuwali; Sebenzisa i-oscilloscope ukuze uhlole ukuthi i-waveform yesiginali ijwayelekile yini.
Shintshanisa inzwa : uma kuqinisekiswa ukuthi inzwa yonakele, buyisela izingxenye zebhrendi zangempela noma ezithembekile (naka indawo ekhishwayo kanye netorque ngesikhathi uyifake).
Hlola uhlelo lwesikhathi : uma iphutha lihlobene nesikhathi (njengamazinyo okweqa ibhande lesikhathi), kudingeka uphinde uhlole umaki wesikhathi.
Sula ikhodi yephutha futhi uyiqalise : sula ikhodi yephutha ngemva kokulungiswa, futhi wenze ukuhlolwa komgwaqo ukuze ubone ukuthi iphutha lisusiwe ngokuphelele yini.
