Indlela yokushintsha i-valve ye-exhaust gas recirculation (EGR)

Imoto yakho ingase ibonise ukukhanya kwe-Check Engine, ingase ingasebenzi kahle, noma ingase ingaphumeleli uhlolo lwendawo ekhishwayo. Lezi kungaba ezinye zezimpawu ezivamile ze-EGR ehlulekile (i-exhaust gas recirculation) valve. I-EGR ayithinti kuphela ngokuqondile ukukhishwa kwemoto yakho, kodwa futhi ingadala izinkinga ezinzima kakhulu zokuphatha imoto yakho. Ukwazi ukuthi i-valve ye-EGR yenzani nokuthi ungayixilonga kanjani kungakusiza wonge imali ngokuzilungisa wena, noma okungenani kukusize ube umthengi onolwazi.

Ingxenye 1 kwezi-3: Ukuqonda injongo yevalvu ye-EGR nendlela esebenza ngayo

Ivalvu ye-EGR noma i-Exhaust Gas Recirculation valve iyingxenye yesistimu yokukhipha umoya wemoto yakho. Inhloso yayo enkulu ukunciphisa ukukhishwa kwe-NOX (oxides of nitrogen) ekhishwa injini yakho. Lokhu kufezwa ngokuphindisela emuva enjinini amagesi akhipha i-exhaust, okumisa izinga lokushisa ekamelweni elivuthayo, futhi kuvumela inqubo yokuvutha ukuthi iqale futhi ku-EGR, okunciphisa inani likaphethiloli ongashiswanga kuyo.

Kunezinhlobo ezimbili zamavalvu e-EGR, i-electronic kanye ne-manual. Inguqulo ye-elekthronikhi iqukethe i-solenoid evumela ikhompuyutha ukuthi ivule futhi iyivale lapho kudingeka. Inguqulo ye-manuwali ivula lapho i-vacuum yenjini isetshenziswa kuyo, bese ivala lapho ikhulula i-vacuum. Kungakhathaliseki ukuthi iyiphi onayo, ukusebenza kwesistimu kuyafana. Ikhompyutha yemoto izolawula ukuvulwa nokuvalwa kwe-valve ye-EGR ngokusekelwe kusivinini semoto kanye nezinga lokushisa lenjini.

Ezimotweni eziningi, i-valve ye-EGR izosetshenziswa kuphela lapho injini ifudunyezwa izinga lokushisa elivamile lokusebenza futhi imoto ihamba ngesivinini somgwaqo omkhulu. Uma isistimu ingasebenzi kahle, ingaholela kokuthile okulula njengokukhanyisa kwe-Check Engine, kokuthile okubucayi njengokumisa injini.

Ingxenye yesi-2 koku-3: Ukuhlonza Ivaluvu ye-EGR Enephutha

I-valve ye-EGR ingahluleka ngenxa yezizathu ezihlukahlukene. Uma lokhu kwenzeka, kungabangela uhla lwezimpawu. Uma i-valve ye-EGR yehluleka, ngokuvamile iyehluleka ngendlela eyodwa kwezimbili: ibambeka ivuleke noma ibambeke ivaleke. Lezi zimpawu zingafana kakhulu nezinye izinkinga zemoto, ngakho ukuxilongwa okufanele kubalulekile.

Hlola ukuthi ilambu lenjini livuliwe yiniA: Uma i-valve ye-EGR yehluleka, ingabangela ukukhanya kwe-Check Engine ukuthi kukhanye. Uma ukukhanya kuvuliwe, ikhompuyutha idinga ukuskenwa ukuze ithole amakhodi. Uma kunekhodi yokugeleza ephansi ye-EGR, kusho ukuthi i-valve ye-EGR ayivuli.

Ikhompiyutha ingakwazi ukubona ukuthi i-valve ye-EGR iyavuleka yini ngezinguquko ezibona kuzinzwa zomoya-mpilo lapho i-valve ivuliwe. Ungathola futhi ikhodi ye-voltage engalungile ye-valve ye-EGR, engabonisa inkinga yesifunda noma ukwehluleka kwe-valve. Ikhodi yengxube encane ingase ivele uma i-valve ye-EGR ibhajwe ivuliwe. Uma i-valve ye-EGR ibhajwe ivuliwe, umoya ongasetshenzisiwe uzongena enjinini, okubangele ukuthi ikhompuyutha ibone umoya omningi enjinini.

Ikhohlakali: Uma i-valve ye-EGR ibambeke endaweni evulekile, izobangela ukuvuza kwe-vacuum. Lokhu kuzoholela ekutheni injini ibambezeleke kancane ngoba ikhompuyutha ngeke ikwazi ukubona kahle umoya oweqile.

Uma kuvela noma iyiphi yalezi zimpawu, i-valve kufanele ihlolwe. Kuya ngokuthi hlobo luni lwemoto, kuzocaciswa ukuthi izobhekwa kanjani.

I-EGR Ayikho/Ikhodi Egelezayo Ephansi: Lokhu kusho ukuthi ayikho igesi ephumayo eyanele engena enjinini lapho kuvulwa i-valve ye-EGR. Lokhu kungase kube ngenxa yezizathu eziningi. Ikhono lokuxilonga ngamunye wabo lizokusiza ukuthi uthole inkinga.

• I-valve ye-elekthronikhi ye-EGR: I-valve ye-EGR ingase ibe nesici noma ibe nokungasebenzi kahle kwesifunda sokulawula. Indlela engcono kakhulu yokuxilonga lokhu ukusebenzisa isithwebuli kuqala. Njengoba injini isebenza, i-valve ye-EGR ingavulwa futhi ivalwe, futhi ungakwazi ukuqapha ukusebenza kwayo okulungile. Uma kungasebenzi, khona-ke udinga ukuhlola i-valve ye-EGR nge-ohmmeter. Uma i-valve ithola imiphumela engemihle, kufanele ishintshwe. Uma konke kuhlelekile, isifunda kufanele sihlolwe nge-voltmeter.

• I-valve ye-EGR ye-Manual: I-valve ye-EGR ye-Manual noma i-solenoid yayo yokulawula noma ukwehluleka kwesifunda kungase kube khona. Ivalvu ye-EGR ingabhekwa ngepompo ye-vacuum ukuze kubonwe ukuthi ibambeke endaweni evaliwe. Njengoba injini isebenza, ungasebenzisa iphampu yevacuum ukuze ufake ivacuum kuvalvu ye-EGR. Uma injini ingasebenzi ishintsha lapho kufakwa i-vacuum, i-valve ilungile. Uma kungenjalo, khona-ke idinga ukushintshwa. Uma i-valve ye-EGR ILUNGILE, hlola umjikelezo wayo wokulawula kanye ne-solenoid.

• Iziteshi ze-EGR ezivaliwe: I-valve ye-EGR ingase futhi ibe yinhle uma uthola ikhodi yenkinga yokugeleza. Amaphaseji e-EGR axhuma i-exhaust kulokho okudlayo avame ukuvaleka nge-carbon buildup. Ngokuvamile i-valve ye-EGR ingasuswa futhi amaphaseji ahlolwe ukuthi afakwe imali yini. Uma kukhona ukunqwabelana, khona-ke kufanele kukhishwe kuqala bese kuphinda kuhlolwe imoto.

Uma inkinga ngemoto ingenxa yekhodi ethambile noma inkinga engenzi lutho, lokhu kubonisa ukuthi i-valve ayivali. I-valve kufanele ikhishwe futhi izingxenye zangaphakathi zingabhekwa ukuthi zihamba ngokukhululeka yini. Uma kungenjalo, khona-ke idinga ukushintshwa.

Ingxenye 3 kwezi-3: Ukushintshwa kwevalvu ye-EGR

Uma i-valve itholwe inesici, kufanele ishintshwe.

Izinto ezidingekayo

• I-valve ye-EGR
• I-ratchet enamasokhethi
• I-Wrench (eyalungiseka)

Isinyathelo 1: Paka imoto yakho endaweni esezingeni.. Paka endaweni esezingeni bese ufaka ibhuleki lokupaka. Vumela injini iphole.

Isinyathelo sesi-2: Thola i-valve ye-EGR. I-valve ye-EGR imvamisa itholakala ku-multifold intake. Isitika sezinto ezikhishwayo ngaphansi kwesivalo singakusiza ukuthi uthole ivalvu.

Isinyathelo sesi-3: Khulula ipayipi le-exhaust. Sebenzisa isikrufu ukuze uxegise ipayipi le-exhaust elixhunywe ku-valve ye-EGR.

Isinyathelo 4: Susa amabhawodi. Usebenzisa i-ratchet nesokhethi efanelekile, susa amabhawodi abambe i-valve endaweni eningi yokudonsa bese ukhipha i-valve.

Isinyathelo sesi-5: Faka i-valve entsha. Faka i-valve entsha ngokuhlehla futhi uqinise amabhawudi ayo anyukayo ekucacisweni komkhiqizi.

Ngemva kokufaka i-valve entsha ye-EGR, ingahlolwa futhi. Uma ukuhlola nokufaka esikhundleni se-valve ye-EGR kubonakala kunzima kakhulu kuwe, kufanele ufune usizo lukamakhenika oqinisekisiwe ongangena esikhundleni se-valve ye-EGR kuwe.
