Umsebenzi we-valve yokulawula inzwa yesigaba se-camshaft yemoto
Indima eyinhloko yevalvu yokulawula inzwa yesigaba se-camshaft ukulawula ukungena nokufuduka kwenjini, ngaleyo ndlela kuthuthukisa ukusebenza kwenjini kanye nokonga uphethiloli . Ngokukhethekile, ivalvu yokulawula ithinta isikhathi sokuvula nokuvala kwevalvu ngokushintsha i-Angle yesigaba se-camshaft, okuthi futhi kuthinte umthamo wokungenisa nokukhipha injini. Lo mthetho ungasiza injini ukuthi ifinyelele ukusebenza kahle kokushisa kanye nokonga ngaphansi kwezimo zokusebenza ezahlukene .
Isimiso sokusebenza
Amavalvu okulawula inzwa yesigaba se-camshaft avame ukusebenza nabalawuli besigaba se-camshaft. Lapho inzwa ithola isimo sokusebenza kwenjini, isignali idluliselwa ku-ECU (iyunithi yokulawula kagesi), bese i-ECU ilungisa indawo yevalvu yokulawula ngokuya ngalezi zimpawu, ngaleyo ndlela ishintshe i-Angle yesigaba se-camshaft. Le nqubo yenziwa ngamanzi noma ngogesi, okungase kuhluke kuye ngemodeli kanye nomklamo .
Umphumela wephutha
Uma i-valve yokulawula ye-sensor phase ye-camshaft yehluleka, ingabangela ukwehla kokusebenza kwenjini, ukwanda kokusetshenziswa kukaphethiloli, kanye nokwanda kokukhishwa komoya. Isibonelo, uma i-valve yokulawula ingalungisi i-Angle yesigaba ngendlela efanele, ingabangela isikhathi se-valve esingafanele, okuthinta ukusebenza kahle kokushisa, okuholela ekusetshenzisweni kwamandla angaphansi kanye nokwanda kokusetshenziswa kukaphethiloli.
Isiphakamiso sokulungisa
Ukuze kuqinisekiswe ukusebenza okuvamile kwevalvu yokulawula inzwa yesigaba se-camshaft, kunconywa ukuhlola nokugcina izingxenye ezifanele njalo. Lokhu kuhlanganisa ukuhlola ikhwalithi kawoyela yesistimu ye-hydraulic, ukuhlanza noma ukufaka esikhundleni izihlungi ezivalekile, nokuhlola njalo ukuxhumana kukagesi. Ngaphezu kwalokho, gwema ukuqhuba imoto isikhathi eside ezindaweni ezinzima ukuze unciphise umonakalo kuvalvu yokulawula .
Izimpawu zokwehluleka kwe-valve yokulawula inzwa yesigaba se-camshaft yezimoto zifaka phakathi:
Ubunzima noma ukungakwazi ukuqala: I-ECU ayikwazi ukuthola isignali yesikhundla se-camshaft, okuholela ekudidekeni kwesikhathi sokuvutha, futhi kunzima ukuqala injini.
ukujitha kwenjini noma ukuwa kwamandla: iphutha lesikhathi sokusha okuholela ekushiseni okunganele, injini ingase ijithe ngezikhathi ezithile, isheshise kancane kancane.
ukusetshenziswa kukaphethiloli okwandisiwe, okwenza ukukhishwa komoya kube kubi kakhulu: I-ECU ingangena "kwimodi ephuthumayo", isebenzisa amapharamitha okujova angaguquki, okuholela ekongeni uphethiloli okubi kanye nokukhishwa komoya okweqile ngokweqile.
Isibani sephutha sivuliwe: uhlelo lokuxilonga olusebhodini (i-OBD) luthola isignali yenzwa engavamile bese luqala ikhodi yephutha (isb. P0340).
ukuminyana noma ukungaminyana: Uma isignali yesenzwa iphazamiseka, i-ECU ingase ingakwazi ukugcina isivinini esijwayelekile sokuminyana, okuholela ekuminyana kwenjini okungazelelwe.
Ukukhishwa kwamandla okulinganiselwe : Amanye amamodeli akhawulela amandla enjini ukuvikela uhlelo .
Izizathu zokwehluleka zingafaka:
Inzwa ngokwayo yonakele: ukuguga kwezingxenye ze-elekthronikhi zangaphakathi, ukwehluleka kwezingxenye zokungenisa amandla kazibuthe, isekethe esifushane noma isekethe evulekile.
Ukwehluleka kwesekethe noma kwepulagi: ipulagi iyashiswa noma ikhululekile, i-harness igugile, ifinyeziwe noma iphukile (isb. ukushisa noma amagundane).
Ukungena kwe-sensor ukungcola noma uwoyela: udoti noma imfucumfucu yensimbi inamathele ebusweni be-sensor, okuthinta ukuqoqwa kwesignali.
Inkinga yokufaka : ukuvuleka okungafanele kwenzwa (isibonelo, ibanga eliphakathi kwenzwa negiya le-camshaft lide kakhulu), izikulufo zokulungisa ezikhululekile .
Okunye ukwehluleka okuhlobene: ukungahambisani kahle kwebhande lesikhathi/uchungechunge, ukwehluleka kwenzwa yesikhundla se-crankshaft, ukwehluleka kwe-ECU, noma ukuphazamiseka kwe-electromagnetic.
Izindlela zokuhlola nokulungisa zifaka:
Funda ikhodi yephutha: Sebenzisa ithuluzi lokuxilonga le-OBD ukuze ufunde ikhodi yephutha (njenge-P0340) bese uqinisekisa ukuthi ingabe yiphutha lenzwa ye-camshaft.
Hlola izintambo zenzwa kanye nepulaki: hlola ukuthi ipulaki ikhululekile, igqwalile, i-wiring harness ayonakele, lungisa noma ufake enye uma kudingeka.
Inzwa ehlanzekile: Susa inzwa bese ususa uwoyela womphezulu noma udoti ngesihlanzi se-carburetor (uqaphela ukugwema umonakalo ongokwenyama).
Linganisa ukumelana kwenzwa noma isignali: Sebenzisa i-multimeter ukuhlola ukuthi ukumelana kwenzwa kuyahlangabezana yini nezindinganiso ezisetshenziswa ngesandla; Sebenzisa i-oscilloscope ukuhlola ukuthi ukuma kwegagasi lesignali kuyinto evamile yini.
Shintsha inzwa: uma kuqinisekiswa ukuthi inzwa yonakele, shintsha izingxenye zomkhiqizo wokuqala noma othembekile (qaphela ukuvuleka kanye ne-torque ngesikhathi sokufakwa).
Hlola uhlelo lwesikhathi: uma iphutha lihlobene nesikhathi (njengokweqa amazinyo ebhande lesikhathi), kudingeka uphinde uhlole uphawu lwesikhathi.
Sula ikhodi yephutha bese uyiqhuba: sula ikhodi yephutha ngemva kokulungisa, bese wenza ukuhlolwa komgwaqo ukuze ubone ukuthi iphutha lisusiwe ngokuphelele yini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
