Xa kuziwa ekusebenzeni kwangaphakathi kwe-injini yakho, zininzi izinto ezidlala indima ebalulekileyo ekuqinisekiseni ukuba isebenza kakuhle.Elinye lala macandelo yivalve spring, enokuthi ibonakale incinci ngobukhulu kodwa ibe nempembelelo enkulu ekusebenzeni ngokubanzi kwe-injini.
Imithombo yevalvu yinxalenye ebalulekileyo yenkqubo ye-injini yevalve kaloliwe.Banoxanduva lokuqinisekisa ukuba iivalve zokungena kunye ne-exhaust zivula kwaye zivale ngamaxesha achanekileyo, ukuvumela umxube we-air-fuel ukuba ungene kwigumbi lokutshisa kunye nokukhupha iigesi.Le nkqubo ibalulekile ukuze injini isebenze ngokufanelekileyo nangempumelelo.
Omnye wemisebenzi ephambili yesipopori sevalvu kukugcina ivalvu icocekile ngendlela eyiyo.Xa i-injini isebenza, iivalve zihlala zinyuka zisihla, kwaye imithombo yevalve iqinisekisa ukuba ibuyela kwindawo evaliweyo emva komjikelo ngamnye.Oku kubalulekile ukuthintela nakuphi na ukuphazamiseka phakathi kweevalvu kunye neepiston, ezinokuthi ngenye indlela zibangele umonakalo omkhulu kwi-injini.
Ukongeza ekugcineni ivalve clearance, imithombo yevalve ikwadlala indima ekulawuleni intshukumo yevalvu.Kufuneka babe namandla ngokwaneleyo ukugcina i-valve ivaliwe ngexesha lokunyanzeliswa kunye nokutshisa, kodwa ukuguquguquka ngokwaneleyo ukuvumela ukuba i-valve ivule xa kufuneka.Oku kufuna ibhalansi eethe-ethe, kwaye uyilo lwe-valve spring kunye nomgangatho ubalulekile ekufezekiseni ukusebenza kakuhle kwe-injini.
Ukongeza, imithombo yevalvu inceda ukuphucula ukuqina kwayo yonke injini.Xa ii-injini zisebenza, zihlala zixinezelekile kwaye zidiniwe, kwaye ukuba azikho kumgangatho womsebenzi, zinokusilela kwangethuba.Oku kunokukhokelela kwinkitha yeengxaki, kuquka ukuphelelwa kwamandla, ukungasebenzi kakuhle kwepetroli, kunye nokusilela kwenjini.
Kukho izinto ezininzi ekufuneka uziqwalasele xa ukhetha imithombo yevalvu yenjini yakho.Imathiriyeli, uyilo kunye noxinzelelo lwe-valve spring zonke zidlala indima ebalulekileyo ekumiseleni ukusebenza kwayo kunye nokuphila ixesha elide.Kubalulekile ukukhetha umthombo wevalvu eyenzelwe ngokukodwa iimfuno ze-injini, kuthathelwa ingqalelo izinto ezifana noluhlu lwe-rpm ye-injini, iprofayili yecamshaft kunye nokusetyenziswa okucetywayo.
Ukugcinwa rhoqo kunye nokuhlolwa kwemithombo yevalvu nako kubalulekile ekuqinisekiseni ukuthembeka nokusebenza kwe-injini.Ngokuhamba kwexesha, imithombo yevalvu iba buthathaka kwaye iphulukane noxinzelelo, nto leyo enokubangela iingxaki ezinje ngevalvu edadayo okanye ukungahambi kakuhle.Ngokubeka esweni imeko yemithombo yevalvu baze bayitshintshe xa kuyimfuneko, abanini-injini banokukuphepha ukulungiswa okuxabisa imali eninzi baze baqinisekise ukuba injini yabo iyaqhubeka isebenza kakuhle.
Isishwankathelo, ngelixa i-valve springs ingaba yincinci ngobukhulu, indima yabo ekusebenzeni kwe-injini ibalulekile.Zibalulekile ekugcineni ukucoceka okufanelekileyo kwevalvu, ukulawula ukuhamba kwevalvu kunye nokuqinisekisa ukuqina kwe-injini.Ngokuqonda ukubaluleka kwemithombo yevalve kunye nokuthatha amanyathelo ayimfuneko ukuzigcina, abanini-injini banokunandipha ukusebenza okuthembekileyo kunye nobomi benkonzo kwiinjini zabo.
