Ukushintsha ama-valve ku-VAZ 2114: izizathu kanye nenqubo yokulungisa
Inkinga enkulu lapho kufanele ushintshe ama-valve ku-VAZ 2114-2115 izimoto - ukuvutha kwabo. Lezi zimo azivamile, kodwa zisenzeka. Lokhu kwenzeka ngezizathu ezihlukahlukene:
- uphethiloli wezinga eliphansi njalo utheleka emotweni
- ukusebenza kwemoto ku-PROPANE ngaphandle kwezinguquko ezihambelanayo ku-firmware yesilawuli
- Inombolo yepulaki ekhanyayo engalungile
- ukuqhunyiswa njalo kwenjini, noma kunalokho, izimbangela zayo
- ukushayela okuvamile ngesivinini esiphezulu (isilinganiso esiphezulu sivumelekile)
Yiqiniso, akuzona zonke izici ezingathinta ukushiswa kwama-valve ezibalwe ngenhla, kodwa amaphuzu ayinhloko asavezwa. Kukhona umzuzu owodwa lapho kuzodingeka ushintshe ama-valve - lokhu uma begobile lapho behlangana nama-pistons. Kodwa lapha - ISEXWAYISO! Ezinjini ezijwayelekile ze-VAZ 2114 ezinamakhanda angama-cylinder angu-8, lokhu angeke kube ngokomthetho.
Kodwa uma une injini ye-valve engu-16, okwenzeka ngisho nakumamodeli wefektri sekwephuzile, ibhande lesikhathi eliphukile lingaholela emiphumeleni edabukisayo. Ngezansi sizocubungula inqubo yokumiselela ngamafuphi, ngemibiko yesithombe ethulwe ngokulungiswa kokuhlangenwe nakho komuntu siqu.
Ukushintsha ama-valve ku-VAZ 2114 - umbiko wesithombe
Ngakho-ke, okokuqala, kuzodingeka ususe ikhanda le-cylinder, ngoba ngaphandle kwalokho akunakwenzeka ukufika kuma-valve. Yiqiniso, kuqala khumula ibhande lesikhathi nakho konke okuzosiphazamisa ngokuqhubekayo, kuhlanganise nesembozo se-valve.
Ngemva kwalokho, sikhulula amabhawodi avikela ikhanda kubhulokhi. Ziyi-10 sezizonke. Ngokuya ngedethi yokukhishwa kwemoto, izoba yi-hexagon noma iphrofayili ye-TORX.
Amabhawodi ohlangothini olulodwa angaphandle, kanti ngakolunye, ngaphakathi kwekhanda, ngakho awabonakali esithombeni. Ngemuva kokuthi zonke zikhishwe, futhi konke okungaphazamisa ukudilizwa kunqanyuliwe, susa ikhanda le-cylinder enjinini:
Kungcono ukususa i-camshaft kusengaphambili, ngoba akulula kakhulu ukuyikhulula ekhanda elisusiwe. Uma isusiwe, ungaqala ukomisa ama-valve.
Ukuze wenze lokhu, udinga idivayisi ekhethekile ebizwa ngokuthi i-desiccant. Futhi, ukuze ikhanda lesilinda lilungiswe ngokuphephile, ungalibuyisela kubhulokhi, bese ucindezela amabhawodi ambalwa ngokudayagonali.
I-cracker rail ifakiwe futhi i-valve ngayinye "iyalungiswa" ngokulandelayo, njengoba kukhonjisiwe esithombeni esingezansi:
Lapho iziphethu ze-valve zisusiwe, ungaqala ukususa izimpawu ze-valve stem. Umphumela uboniswa ngokucacile esithombeni esingezansi.
Ngemva kwalokho, ungakwazi ukususa kalula i-valve emkhonweni wayo womhlahlandlela kusukela ngaphakathi kwekhanda.
Amanye ama-valve akhishwa ngokulandelana okufanayo. Lapho ufaka ama-valve amasha, kuzodingeka ukuthi agaywe. Ukuze uzijwayeze ngale nqubo, bukela isiqeshana sevidiyo, lapho konke lokhu kuboniswa khona.
Ividiyo ye-Valve Lapping
Ukubuyekezwa kwenziwe ngu-Evgeny Travnikov, owaziwa yiso sonke isiteshi sakhe se-YouTube Theory of Internal Combustion Engines:
Lapho ekugcineni usuqedile wonke umsebenzi, ungakwazi ukufaka zonke izingxenye ezisusiwe ngokulandelana okuphambene emotweni. Ngokuqondene nentengo yesethi yama-valve amasha, imayelana nama-ruble ayi-1500. Uma uthenga ngokwehlukana, khona-ke izindleko kulula ukuzithola ngokuhlukanisa inani ngo-8.
