Uma kukhulunywa ngokusebenza kwangaphakathi kwenjini yakho, ziningi izingxenye ezidlala indima ebalulekile ekuqinisekiseni ukuthi isebenza kahle.Enye yalezi zingxenye i-valve spring, engase ibonakale incane ngosayizi kodwa ibe nomthelela omkhulu ekusebenzeni kahle kwenjini.
Iziphethu ze-valve ziyingxenye ebalulekile yesistimu yesitimela se-valve yenjini.Banomthwalo wemfanelo wokuqinisekisa ukuthi amavalvu okungenisa nawokukhipha umoya avuleka futhi avale ngezikhathi ezifanele, okuvumela ingxube yamafutha omoya ukuthi ingene egumbini elivuthayo namagesi akhipha umoya.Le nqubo ibalulekile ukuze injini isebenze ngendlela efanele nangempumelelo.
Omunye wemisebenzi esemqoka yesiphethu se-valve ukugcina ukuvuleka kwe-valve ngendlela efanele.Lapho injini isebenza, ama-valve ahlala ehla enyuka, futhi iziphethu ze-valve ziqinisekisa ukuthi zibuyela endaweni evaliwe ngemva komjikelezo ngamunye.Lokhu kubalulekile ukuvimbela noma yikuphi ukuphazamiseka phakathi kwamavalvu namapiston, okungadala umonakalo omkhulu enjinini.
Ngaphezu kokugcina imvume yama-valve, iziphethu ze-valve nazo zidlala indima ekulawuleni ukunyakaza kwama-valve.Kudingeka zibe namandla ngokwanele ukugcina i-valve ivaliwe ngesikhathi sokucindezelwa nokuvutha, kodwa ikwazi ukuguquguquka ngokwanele ukuvumela i-valve ukuthi ivule lapho kudingeka.Lokhu kudinga ibhalansi ethambile, futhi ukwakheka kwe-valve spring kanye nekhwalithi kubalulekile ukuze kuzuzwe ukusebenza kahle kwenjini.
Ukwengeza, iziphethu ze-valve zisiza ukuthuthukisa ukuqina okuphelele kwenjini yakho.Lapho izinjini zisebenza, zibhekana nokucindezeleka nokukhathala njalo, futhi uma zingekho ezingeni elifanele, zingase zehluleke ngaphambi kwesikhathi.Lokhu kungaholela ezinkingeni eziningi, ezihlanganisa ukuphelelwa amandla, ukungasebenzi kahle kukaphethiloli, ngisho nokungasebenzi kahle kwenjini.
Kunezici eziningana okufanele uzicabangele lapho ukhetha ama-valve springs enjini yakho.Impahla, ukwakheka kanye nokushuba kwesiphethu se-valve konke kudlala indima ebalulekile ekunqumeni ukusebenza kwayo nokuphila isikhathi eside.Kubalulekile ukukhetha isiphethu se-valve esiklanyelwe ngqo izidingo zenjini, kucatshangelwa izici ezifana nebanga le-rpm yenjini, iphrofayili ye-camshaft kanye nokusetshenziswa okuhlosiwe.
Ukugcinwa njalo nokuhlolwa kwama-valve springs nakho kubalulekile ekuqinisekiseni ukwethembeka nokusebenza kwenjini.Ngokuhamba kwesikhathi, iziphethu ze-valve ziba buthaka futhi zilahlekelwe ukushuba, okungabangela izinkinga ezifana nokuntanta kwe-valve noma ukungahambi kahle.Ngokuqapha isimo seziphethu zama-valve nokuwashintsha lapho kudingeka, abanikazi bezinjini bangagwema ukulungiswa okumba eqolo futhi baqinisekise ukuthi injini yabo iyaqhubeka nokusebenza kahle.
Kafushane, kuyilapho iziphethu ze-valve zingase zibe zincane ngosayizi, indima yazo ekusebenzeni kwenjini ibalulekile.Zibalulekile ekugcineni ukuvunyelwa kwama-valve ngendlela efanele, ukulawula ukunyakaza kwama-valve nokuqinisekisa ukuqina kwenjini.Ngokuqonda ukubaluleka kweziphethu zamavalvu nokuthatha izinyathelo ezidingekayo ukuze zigcinwe, abanikazi bezinjini bangajabulela ukusebenza okuthembekile nokuphila kwesevisi ezinjinini zabo.
