Umsebenzi we-starve yesigaba se-automats control valve
Iqhaza eliphambili le-Camshaft Isigaba Sensor Control Valve ukulawula ukuthathwa kanye nokusuka enjini, ngaleyo ndlela kuthuthukiswe ukusebenza kwe-Injini kanye noMnotho Omnotho. Ngokukhethekile, i-valve yokulawula ithinta isikhathi sokuvula nokuvala isikhathi se-valve ngokushintsha isengezo sesigaba se-camshaft, okuthinta umthamo wenjini. Lo mthethonqubo ungasiza injini ukufeza ukusebenza kahle kanye nomnotho omuhle kakhulu ngaphansi kwezimo ezihlukile zokusebenza.
Umgomo Wokusebenza
Ama-valves esigamenti se-Camshaft Sensor ajwayele ukusebenza nama-aurterator esigaba se-camshaft. Lapho inzwa ithola isimo sokusebenza kwenjini, isiginali idluliselwa kwi-ECU (iyunithi yokulawula ngogesi), futhi i-ECU iguqula isikhundla se-valve yokulawula ngokuya ngalezi zimpawu, ngaleyo ndlela eshintsha i-angle engela ye-camshaft. Le nqubo yenziwa noma nge-hydraulically noma ngogesi, okungahluka ngokuya ngemodeli nokuklanywa.
Umphumela wephutha
Uma i-camshaft isigaba sokulawula i-valve yehluleka, kungahle kuholele ekunciphiseni ukusebenza kwenjini, ukwanda kokusetshenziswa kwamafutha, kanye nokukhishwa okubangelwa. Isibonelo, uma i-valve yokulawula ingaguquli i-angle yesigaba kahle, kungahle kube nomphumela wokuqamba isikhathi se-valve esinganembile, okuthinta ukusebenza kahle kokuhlangana, okuholele ekusetshenzisweni kwamafutha.
Isiphakamiso sesondlo
Ukuze uqinisekise ukusebenza okujwayelekile kwe-camshaff ganal sensor control valve, kunconyelwa ukubheka nokugcina izingxenye ezifanele njalo. Lokhu kufaka ukubheka ikhwalithi yamafutha yohlelo lwe-hydraulic, ukuhlanza noma ukufaka esikhundleni izihlungi ezivalekile, nokuhlola njalo ukuxhumeka kukagesi. Ngaphezu kwalokho, gwema ukusebenzisa imoto isikhathi eside ezindaweni ezinokhahlo ukuze unciphise ukulimala kwe-valve yokulawula.
Izimpawu ze-Methototive Camshaft Isigaba Sokulawula Ukulawulwa Kwe-Valve ngokuhamba kwesikhathi:
Ubunzima noma ukungakwazi ukuqala: I-ECU ayikwazi ukuthola isiginali yesikhundla se-camshaft, okuholela ngesikhathi sokudideka isikhathi, futhi injini inzima ukuqala.
I-Enjini Jitter noma i-Power Drop: Iphutha lesikhathi sokulahla eliphumela ekuthambukeni okunganele, injini ingahlala ihlasela, ibuthakathaka ukushesha.
Ukwanda kokusebenzisa uphethiloli, ukuphuma okuba yingozi: I-ECU ingafaka "imodi ephuthumayo", isebenzisa amapharamitha ahleliwe umjovo, okuholela emnothweni kaphethiloli ompofu nokukhishwa ngokweqile kokukhipha.
Ukukhanya kwe-Fault kuvuliwe
I-stalling noma engazinzile, lapho isinali yezinzwa siphazamiseka, i-ECU kungenzeka ingakwazi ukugcina isivinini esingejwayelekile esingenzi lutho, okuholela ekutheni injini ezungeza i-stalling.
Ukukhishwa kwamandla okulinganiselwe: Amanye amamodeli alinganise amandla enjini ukuvikela uhlelo.
Izizathu zokwehluleka zingafaka:
Inzwa ngokwayo ilimele: Ukuguga kwezinto zangaphakathi ze-elekthronikhi, ukwehluleka kwezakhi zokungeniswa kazibuthe, umjikelezo omfushane noma umjikelezo ovulekile.
I-Circuit noma ukwehluleka i-plug: I-plug i-oxidised noma i-plug, i-harness igqokwa, isizungu esifushane noma esiphukile (isib. Ngokushisa noma amagundane).
Ukungcola kwe-Sensor noma ukungena kwamafutha: I-Sludge noma imfucumfucu yensimbi inamathiselwe ebusweni bezinzwa, okuthinta ukuqoqwa kwesiginali.
Inkinga yokufaka: imvume engafanele yenzwa (ngokwesibonelo, ibanga phakathi kwenzwa kanye negiya le-camshaft likude kakhulu), izikulufo ezilungiselelwe.
Okunye ukwehluleka okuhambisana nakho: Isikhathi se-Belt / Chain Milalignment, ukwehluleka kwe-crankshaft isikhundla sezinzwa, ukwehluleka kwe-ECU, noma ukuphazamiseka kwe-electromagnetic.
Izindlela zokuhlola nokulungisa zifaka:
Funda ikhodi yephutha: Sebenzisa ithuluzi lokuxilonga le-OBD ukuze ufunde ikhodi yephutha (efana ne-P0340) bese uqinisekisa ukuthi ngabe yiphutha lezinzwa le-camshaft.
Hlola i-wiring ye-sensor ne-plug: hlola ipulaki okuxegayo, ukugcwaliswa, amahhanisi we-wiring awonakalisiwe, alungise noma athathe indawo uma kunesidingo.
Inzwa ehlanzekile: Susa inzwa futhi ususe uwoyela ongaphezulu noma imfucumfucu nge-carburetor cleaner (ukunakekela ukugwema ukulimala ngokomzimba).
Ukukala ukumelana sensor noma isiginali: Sebenzisa i-multimeter ukuvivinya ukuthi ukumelana sensor kuhlangana kanjani nemanyuki; Sebenzisa i-Oscilloscope ukubheka ukuthi ngabe i-wavelform yesiginali ijwayelekile.
Faka esikhundleni senzwa: Uma kuqinisekisiwe ukuthi inzwa ilimele, ifaka izingxenye zohlobo lwangempela noma oluthembekile (lalelisisa imvume ne-torque ngesikhathi sokufakwa).
Hlola uhlelo lwesikhathi: Uma iphutha lihlobene nesikhathi (njengebhande lesikhathi seqa amazinyo), kudingeka lihlole kabusha uphawu lwesikhathi.
Sula ikhodi yephutha bese uyiqhuba: Sula ikhodi yephutha ngemuva kokulungiswa, futhi wenze ukuhlolwa komgwaqo ukuze ubone ukuthi ngabe iphutha lisuswe ngokuphelele yini.
