Hlanganisa ikhanda lesilinda, noma yimuphi umlungisi nomshayeli angakwenza. Kodwa kungani kutholakala ukuthi ikhanda le-cylinder likhubazekile noma i-cylinder head gasket ibhujiswa ngokushesha ngemva kokufakwa kwekhanda le-cylinder?

Esokuqala sidalwa wumcabango wokuthi "ukhetha ukuqina kunokuxega". Kuyiphutha ukuthi i-torque eyengeziwe yamabhawudi ingathuthukisa ukusebenza kokuvala kwe-cylinder gasket. Lapho uhlanganisa ikhanda le-cylinder, amabhawodi ekhanda le-cylinder avame ukuqiniswa nge-torque eyeqile. Eqinisweni, lokhu akulungile. Ngenxa yalokhu, izimbobo ze-cylinder block bolt zikhubazekile futhi ziphume, okuholela ekuhlanganiseni okungalingani. Amabhawodi ekhanda le-cylinder nawo anwetshiwe (i-plastic deformation) ngenxa yokucindezeleka okweqile njalo, okunciphisa amandla okucindezela phakathi kwezindawo ezihlangene futhi azilingani.

Okwesibili, isivinini sivame ukufunwa lapho kuhlanganiswa ikhanda le-cylinder. Ukungcola okufana nodaka, amafayili ensimbi, nesikali emigodini yesikulufu akususiwe, ukuze kuthi lapho amabhawodi eqiniswa, ukungcola okusezimbotsheni zesikulufu kuthwala impande yebhawodi, okubangela ukuba i-torque yebhawodi ifinyelele inani elishiwo, kodwa ibhowudi ayibonakali iqinisiwe, okwenza isilinda Amandla okucindezela ekhava anganele.

Okwesithathu, lapho uhlanganisa i-bolt yekhanda le-cylinder, i-bolt yafakwa ngenxa yokuthi i-washer ayitholakalanga isikhashana, okwabangela ukuthi indawo yokuxhumana ngaphansi kwekhanda le-bolt igqoke ngemva kokusetshenziswa isikhathi eside. Ngemva kokukhishwa kwekhanda le-cylinder ukuze kugcinwe injini, amabhawodi asegugile aphinde afakwe kwezinye izingxenye, okubangela ukuthi ubuso bonke bokuphela kwesilinda buhluleke ukulingana. Ngenxa yalokho, ngemva kokuba injini isetshenziswe isikhathi esithile, ama-bolts ayaxega, okuthinta amandla okucindezela ekhanda le-cylinder.

Okwesine, ngezinye izikhathi i-gasket ilahlekile, vele uthole i-gasket enencazelo enkulu kunalokho.

Ngaphambi kokufaka ikhanda le-cylinder, sula ubuso obuhlangene bekhanda le-cylinder kanye nomzimba we-cylinder uhlanzekile.
