Iyini isembozo se-valve?
Isembozo se-valve siyipuleti lesimbozo elisetshenziselwa ukuvikela i-camshaft ngaphezu kwegumbi le-valve futhi kwakhiwe umgodi ocishe uvalwe ngekhanda lesilinda (kukhona nezindlela zokubuyisa uwoyela, izindlela zokunikeza uwoyela kanye nezinye izindlela zokuhambisa uwoyela ezixhunywe nezinye izikhala)
Iyini imbangela yokuvuza komoya esembozweni sevalvu?
Ukuvuza komoya okuvela ekhava yevalvu kuzokwenza imoto ingakwazi ukushayela. Uma ingxube icebile kakhulu noma incane kakhulu, uwoyela osegumbini lokusha awushiswa ngokuphelele, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe. Kuzokwenza futhi imoto isheshise kancane. Injini kunzima ukuyiqala, amandla ayancipha, ukusha akuphelele, idiphozithi yekhabhoni inzima, futhi ngisho namasilinda ngamanye ngeke asebenze. Ngokuvamile, uma kukhona ukuvuza kukawoyela, kunconywa ukuthi kushintshwe isembozo sevalvu.
Ingabe kunendaba ukuthi i-gasket yesembozo se-valve ivuza uwoyela?
I-gasket yesembozo se-valve ivuza uwoyela, okusathinta imoto. Kufanele ishintshwe ngesikhathi. I-gasket yesembozo se-valve isetshenziselwa kakhulu ukuvala ukuvimbela ukuvuza kwamafutha. Uma ingashintshwa ngesikhathi, isembozo sizoncipha, siqine, silahlekelwe ukuqina futhi size siphuke kakhulu. Uma kungukuvuza kwamafutha okubangelwa ukuguga kwekhanda lesilinda se-valve, inkinga ingaxazululwa ngokufaka ikhanda lesilinda se-valve elisha esikhundleni salo. Uma uzithengela wena, intengo ingama-yuan ayi-100. Uma uya esitolo se-4S ukuze ulishintshe, lizoba okungenani ama-yuan angama-200. I-gasket yesembozo se-valve ngokuvamile yenziwe ngerabha, futhi esinye sezici ezinkulu zerabha ukuguga. Ngakho-ke, uma impilo yenkonzo yemoto inde kakhulu, izinto zerabha zizoguga futhi ziqine, okuholela ekuvuthweni kwamafutha. Uma ushintsha, naka amaphuzu alandelayo. Uma ushintsha, hlanza ngokuphelele indawo yokuxhumana. Faka i-glue uma ungakwazi, ngoba kuthatha isikhathi eside ukufaka i-glue. Kulungile ukungafaki i-glue. Kuya ngezifiso zomnikazi. 2. Injini kumele ipholiswe ngokuphelele ngaphambi kokuba ishintshwe. 3. Uma ufaka isembozo sevalvu, siqinise izikhathi eziningana ngokuphambene. Ngemva kokulungisa isikulufu, buyela emuva kusikulufu esiphambene. Lokhu kuzovimbela ukucindezeleka okungalingani kugasket yesembozo sevalvu.
Isembozo sevalvu sibukeka kanjani sibi?
Ngokuvamile kunezizathu eziningana zokulimala kwe-gasket yesembozo se-valve. Esokuqala ukuthi i-bolt ikhululekile, esesibili ukushaywa yinjini, esesithathu ukuqhekeka kwesembozo se-valve, kanti esesine ukuthi i-gasket yesembozo se-valve yonakele noma ayigqokwanga nge-sealant.
Ngesikhathi injini icindezelwa, inani elincane legesi lizogeleza lisuka odongeni lwesilinda kanye nendandatho yepiston liye ku-crankcase, futhi ingcindezi ye-crankcase izokhuphuka ngokuhamba kwesikhathi. Ngalesi sikhathi, i-crankcase ventilation valve isetshenziselwa ukuhola le ngxenye yegesi iye ku-intake manifold bese iyimunca ekamelweni lokushisa ukuze iphinde isetshenziswe. Uma i-crankcase ventilation valve ivinjiwe, noma isikhala phakathi kwendandatho yepiston nodonga lwesilinda sikhulu kakhulu, okuholela ekungeneni komoya ngokweqile kanye nengcindezi ephezulu ye-crankcase, igesi izovuza ezindaweni ezinokuvalwa okubuthakathaka, njenge-valve cover gasket, izivalo zamafutha ze-crankshaft zangaphambili nangemuva, okuholela ekuphumeni kwamafutha enjinini.
Uma nje ufaka i-sealant, uqinisa amabhawodi, futhi isembozo se-valve asiqhekekile noma asiguquki, kukhombisa ukuthi isembozo se-valve sihle. Uma ungakhululekile, ungasebenzisa irula kanye ne-geji yokujiya (feeler gauge) ukukala ukuthi isembozo se-valve sithe tyaba yini ukuze ubone ukuthi asiguquki yini.
