Iyini ikhava yevalvu?
Isembozo se-valve iyicwecwe lekhava elisetshenziselwa ukuvikela i-camshaft ngaphezu kwegumbi le-valve futhi lenze indawo ecishe ivaliwe enekhanda le-cylinder (kuphinde kube khona amaphaseji okubuyisela uwoyela, amaphaseji okuphakelwa kukawoyela nezinye izindlela zikawoyela ezixhunywe neminye imigodi)
Iyini imbangela yokuvuza komoya kukhava yevalvu?
Ukuvuza komoya kukhava yevalvu kuzokwenza imoto ingakwazi ukushayela. Uma ingxube icebile kakhulu noma incane kakhulu, amafutha ekamelweni elivuthayo awashiswa ngokuphelele, okuholela ekusetshenzisweni kwamafutha okwenyuka. Kuzophinde kudale ukuthi imoto ijubane kancane. Injini kunzima ukuyiqala, amandla ayancipha, ukushisa akuphelele, idiphozi ye-carbon iyingozi, ngisho namasilinda ngamanye ngeke asebenze. Ngokuvamile, uma kukhona ukuvuza kwamafutha, kunconywa ukuthi kushintshwe ikhava ye-valve
Ingabe kunendaba ukuthi ikhava ye-valve gasket ivuza uwoyela?
I-valve cover gasket ivuza uwoyela, okusathinta imoto. Kufanele ishintshwe ngesikhathi. I-valve cover gasket isetshenziselwa ikakhulukazi ukuvala ukuvimbela ukuvuza kwamafutha. Uma ingashintshwa ngesikhathi, uphawu luzoncipha, lube lukhuni, lulahlekelwe ukunwebeka futhi luphule kakhulu. Uma kumane kuwukuvuza kwamafutha okubangelwa ukuguga kwekhanda le-valve cylinder, inkinga ingaxazululwa ngokufaka entsha esikhundleni sekhanda lesilinda se-valve. Uma uzithengela wena, intengo cishe i-yuan eyi-100. Uma uya esitolo se-4S ukuze uyishintshe, izoba okungenani ama-yuan angu-200. I-valve cover gasket ngokuvamile yenziwe ngerabha, futhi esinye sezici eziyinhloko zenjoloba ukuguga. Ngakho-ke, uma impilo yesevisi yemoto iyinde kakhulu, izinto zenjoloba zizoguga futhi zibe lukhuni, okuholela ekuvuzeni kwamafutha. Lapho ufaka esikhundleni, naka amaphuzu alandelayo. Lapho ushintsha, hlanza ngokuphelele indawo yokuxhumana. Faka i-glue uma ukwazi, ngoba kuthatha isikhathi eside ukusebenzisa i-glue. Kulungile ukungafaki iglue. Kuya ngezifiso zomnikazi. 2. Injini kumele ipholiswe ngokuphelele ngaphambi kokuthi ishintshwe. 3. Uma ufaka ikhava ye-valve, yiqinise izikhathi eziningana nge-diagonally. Ngemva kokulungisa isikulufu, buyela emuva kusikulufu se-diagonal. Lokhu kuzovimbela ukucindezeleka okungalingani ku-gasket yekhava ye-valve.
Ikhava ye-valve ibonakala kanjani kabi?
Ngokuvamile kunezizathu ezimbalwa zokulimala kwe-valve cover gasket. Esokuqala ukuthi ibhawodi lixega, okwesibili ukushaywa kwenjini, okwesithathu ukuqhekeka kwesembozo se-valve, kanti okwesine ukuthi i-gasket yekhava ye-valve yonakalisiwe noma ayivalwanga nge-sealant.
Ngesikhathi sokucindezelwa kwenjini, inani elincane legesi lizogeleza lisuka odongeni lwesilinda kanye neringi yepiston liye ku-crankcase, futhi umfutho we-crankcase uzokhuphuka ngokuhamba kwesikhathi. Ngalesi sikhathi, i-valve ye-crankcase ventilation isetshenziselwa ukuholela le ngxenye yegesi endaweni eningi yokuyithatha futhi iyimunce ekamelweni elivuthayo ukuze iphinde isetshenziswe. Uma i-valve ye-crankcase ventilation ivinjiwe, noma imvume phakathi kweringi ye-piston kanye nodonga lwesilinda inkulu kakhulu, okuholela ekushintsheni komoya okweqile kanye nomfutho we-crankcase ophezulu, igesi izovuza ezindaweni ezinokuvalwa okubuthakathaka, njenge-valve cover gasket. , izigxivizo zamafutha e-crankshaft zangaphambili nangemuva, okuholela ekuvuzeni kukawoyela enjini.
Uma nje usebenzisa i-sealant, qinisa ama-bolts, futhi ikhava ye-valve ayiqhekeki noma ikhubazekile, ibonisa ukuthi isembozo se-valve sihle. Uma ungakhululekile, ungasebenzisa irula kanye negeji yokujiya (igeji ye-feeler) ukukala ukucaba kwekhava yevalvu ukuze ubone ukuthi ayiwohloki yini.
