Yintoni isigqubuthelo sevalvu?
Isigqubuthelo sevalvu sisigqubuthelo esisetyenziselwa ukukhusela i-camshaft engaphezulu kwegumbi levalvu kwaye senze umngxuma ophantse uvalwe ngentloko yesilinda (kukwakho neendlela zokubuyisela ioyile, iindlela zokuhambisa ioyile kunye nezinye iindlela zeoyile ezidibene nezinye iindawo)
Yintoni ebangela ukuvuza komoya kwisigqubuthelo sevalvu?
Ukuvuza komoya kwisiciko sevalvu kuya kubangela ukuba imoto ingakwazi ukuqhuba. Ukuba umxube utyebile kakhulu okanye ubhityile kakhulu, ioyile ekwigumbi lokutsha ayitshi ngokupheleleyo, nto leyo ebangela ukuba ukusetyenziswa kwepetroli kunyuke. Kuya kubangela nokuba imoto ikhawuleze kancinci. Injini kunzima ukuyiqalisa, amandla ayancipha, ukutsha akuphelelanga, idipozithi yekhabhoni imbi kakhulu, kwaye neesilinda nganye aziyi kusebenza. Ngokubanzi, ukuba kukho ukuvuza kweoyile, kuyacetyiswa ukuba kutshintshwe isigqubuthelo sevalvu.
Ingaba kubalulekile na ukuba i-gasket yesigqubuthelo sevalvu ivuza ioyile?
I-gasket yesigqubuthelo sevalvu ivuza ioyile, nto leyo esachaphazela imoto. Ifanele itshintshwe ngexesha. I-gasket yesigqubuthelo sevalvu isetyenziselwa kakhulu ukuvala ukuthintela ukuvuza kweoyile. Ukuba ayitshintshwanga ngexesha, isigqubuthelo siya kuncipha, siqine, silahlekelwe bubuthambile kwaye siqhekeke kakhulu. Ukuba kukuvuza kweoyile okubangelwa kukwaluphala kwentloko yesigqubuthelo sevalvu, ingxaki ingasonjululwa ngokutshintsha intloko yesigqubuthelo sevalvu ngentsha. Ukuba uyithenga ngokwakho, ixabiso limalunga ne-100 yuan. Ukuba uya kwivenkile ye-4S ukuyitshintsha, iya kuba yi-200 yuan ubuncinane. I-gasket yesigqubuthelo sevalvu ngokubanzi yenziwe ngerabha, kwaye enye yeempawu eziphambili zerabha kukuguga. Ke ngoko, ukuba ubomi benkonzo yesithuthi bude kakhulu, izinto zerabha ziya kuguga kwaye ziqine, nto leyo ebangela ukuvuza kweoyile. Xa utshintsha, qaphela la manqaku alandelayo. Xa utshintsha, coca ngokupheleleyo umphezulu woqhagamshelwano. Faka iglu ukuba unako, kuba kuthatha ixesha elide ukufaka iglu. Kulungile ukungafaki iglu. Kuxhomekeke kwiminqweno yomnini. 2. Injini kufuneka ipholiswe ngokupheleleyo ngaphambi kokuba itshintshelwe kwenye. 3. Xa ufaka isigqubuthelo sevalvu, yiqinise izihlandlo ezininzi nge-diagonal. Emva kokulungisa isikrufu, buyela kwi-diagonal screw. Oku kuya kuthintela uxinzelelo olungalinganiyo kwi-gasket yesigqubuthelo sevalvu.
Isigqubuthelo sevalvu sibonakala sibi njani?
Kukho izizathu ezininzi zokonakala kwegasket yesigqubuthelo sevalvu. Esokuqala kukuba ibolt ikhululekile, esesibini kukubhudla kwenjini, esesithathu kukuqhekeka kwesigqubuthelo sevalvu, kwaye esesine kukuba igasket yesigqubuthelo sevalvu yonakele okanye ayigqunywanga ngesitywina.
Ngexesha lokuxinwa kwenjini, inani elincinci legesi liya kuphuma eludongeni lwesilinda kunye neringi yepiston ukuya kwi-crankcase, kwaye uxinzelelo lwe-crankcase luya kunyuka ngokuhamba kwexesha. Ngeli xesha, i-crankcase ventilation valve isetyenziselwa ukukhokela le nxalenye yegesi kwi-intake manifold kwaye iyifunxe kwigumbi lokutsha ukuze isetyenziswe kwakhona. Ukuba i-crankcase ventilation valve ivaliwe, okanye indawo ephakathi kweringi yepiston kunye nodonga lwesilinda inkulu kakhulu, nto leyo ebangela ukuba umoya ujikeleze kakhulu kwaye uxinzelelo lwe-crankcase luphezulu, igesi iya kuvuza kwiindawo ezine-sealing ebuthathaka, njenge-valve cover gasket, i-front and rear crankshaft oil seals, nto leyo ebangela ukuba injini ivuza ioyile.
Ukuba nje ufaka i-sealant, uqinise iibholithi, kwaye isigqubuthelo sevalvu asiqhekekanga okanye asiguquki, oko kubonisa ukuba isigqubuthelo sevalvu silungile. Ukuba awukhululekanga, ungasebenzisa irula kunye negeyiji yobukhulu (feeler gauge) ukulinganisa ukuba isigqubuthelo sevalvu sithe tyaba na ukuze ubone ukuba asiguquki na.
