I-head gasket iyingxenye ebalulekile enjinini evuthayo.I-head gasket iqinisekisa ukuthi ingcindezi edalwe kusukela ekuthuthweni kwe-spark plug ye-fuel vapour ihlala ngaphakathi kwegumbi elivuthayo.Igumbi lomlilo liqukethe ama-pistons futhi lidinga inani eliphezulu lokucindezela ukuze kuqinisekiswe ukuthi ama-piston ayaqhubeka nokudubula ngendlela efanele.Ukwengeza, uwoyela nezinto zokupholisa zinemisebenzi ebaluleke ngokulinganayo kodwa, ukuze zenze imisebenzi yazo ngempumelelo, azikwazi ukuhlangana.I-gasket yekhanda igcina amagumbi ehlukanisiwe ukuze kuqinisekiswe ukuthi akukho ukungcoliswa okuphambene koketshezi.
Umsebenzi we-gasket ye-cylinder ye-injini yilokhu: uphawu, okuyisici sokuvala esinwebekayo esibekwe phakathi kwe-cylinder block kanye nekhanda le-cylinder.Njengoba kungenakwenzeka ukuba isicaba ngokuphelele phakathi kwe-cylinder block kanye nekhanda le-cylinder, i-cylinder head gasket iyadingeka ukuvimbela igesi ephezulu yokucindezela, uwoyela wokugcoba kanye namanzi apholisayo ukuthi angaphumi phakathi kwawo.
Izinto ze-cylinder head gasket ngokuvamile zihlukaniswa zibe izinhlobo ezimbili:
(1) Umata we-asbestos wensimbi usebenzisa i-asbestos njenge-matrix futhi usongwe ngesikhumba sethusi noma sensimbi.Abanye basebenzisa intambo yensimbi ephothiweyo noma ipuleti lensimbi eligoqiwe njengohlaka lwamathambo, kanti abanye bengeza izindandatho zensimbi eduze kwembobo yesilinda ukuze kwandiswe amandla.Inzuzo ukuthi intengo iphansi, kodwa amandla aphansi.Ngenxa yokuthi i-asbestos inemiphumela ye-carcinogenic emzimbeni womuntu, iye yayekwa emazweni athuthukile.
(2) I-gasket yensimbi yenziwe ngocezu olulodwa lwepuleti lensimbi elibushelelezi, futhi kunezingqimba ezinwebekayo endaweni yophawu, evalwa ukunwebeka kwama-ridge kanye nomsebenzi wesivalo esikwazi ukumelana nokushisa.Isetshenziswe kabanzi phesheya.Izinzuzo zingamandla aphezulu, umphumela omuhle wokuvala uphawu, kodwa izindleko eziphezulu.
Ukushintsha i-gasket yekhanda akuyona into ongayenza egaraji.Ungakhohliswa ubulula be-gasket yekhanda njengoba udinga ukuqaqa zonke izingxenye zenjini ukuze uyifinyelele.Kungcono ukushiyela lo msebenzi kochwepheshe.Osekusele kuwumthwalo wemfanelo wokuthatha izinyathelo ngaphambi kokuba kwenzeke okubi kakhulu.Ngamanye amazwi, ukuvimbela i-gasket yekhanda elishaywayo kanye nezindleko zokulungisa i-gasket yekhanda eliphezulu kungenziwa ngesevisi evamile yesistimu yokupholisa.Uma kubhekwa intengo ephansi yezingxenye zesistimu yokupholisa, kuwukuhlakanipha ukuzishintsha esikhundleni lapho kudingeka bese ukhokha izinkulungwane zamaRandi ukuze kulungiswe izinto ezinkulu.
