Izinga le-cylinder head sealing performance linomthelela omkhulu esimweni sobuchwepheshe senjini. Uma ikhanda le-cylinder lingavaliwe ngokuqinile, isilinda sizovuza umoya, okuholela ekucindezelekeni okwanele kokucindezela kwesilinda, izinga lokushisa eliphansi kanye nekhwalithi yomoya ephansi. Lapho ukuvuza komoya kwe-cylinder kungathí sina, amandla enjini azoncishiswa kakhulu, futhi ngeke asebenze. Izizathu eziyinhloko ezithinta ukusebenza kokuvalwa kwekhanda le-cylinder yenjini zibalwe ngezansi.

1. Ukusetshenziswa okungalungile nokufakwa kwe-cylinder head gasket

I-cylinder gasket ifakwe phakathi kwe-cylinder block yenjini kanye nekhanda le-cylinder. Umsebenzi wawo ukuqinisekisa ukuvalwa kwegumbi elivuthayo nokuvimbela ukuvuza kwegesi, amanzi okupholisa namafutha okugcoba. Ngakho-ke, ukusetshenziswa okungafaneleki nokufakwa kwe-cylinder head gasket kuthinta ngokuqondile ukuthembeka kokuvala kwekhanda le-cylinder kanye nempilo yesevisi ye-cylinder head gasket. Ukuze uqinisekise ikhwalithi yokuvala, i-gasket ye-cylinder ekhethiwe kufanele ibe nobukhulu obufanayo kanye nobukhulu obufana ne-cylinder yasekuqaleni, ubuso kufanele bube flat, unqenqema luboshwe ngokuqinile, futhi akukho mihuzuko, amazinyo, imibimbi nokugqwala. Uma kungenjalo, kuzothinta ikhwalithi yokuvala yekhanda lesilinda.

2. Ukuphuma kancane kwekhanda lesilinda

Ukugxuma okuncane kwekhanda le-cylinder kuwumphumela wekhanda le-cylinder elizama ukuhlukana ne-cylinder block ngaphansi komphumela wokucindezelwa nokucindezela kokuvutha. Lezi zingcindezi zandisa amabhawodi axhumayo ekhanda lesilinda, ngaleyo ndlela kubangele ukweqa okuncane kwekhanda lesilinda ngokuhlobene nebhulokhi yesilinda. Lokhu kugxuma okuncane kuzobangela ukuthi i-cylinder head gasket ikhululeke futhi icindezele, ngaleyo ndlela kusheshise umonakalo we-cylinder head gasket futhi kuthinte ukusebenza kwayo kokuvala.

3. Ibhawodi yokuxhuma yekhanda le-cylinder ayifinyeleli inani le-torque elishiwo

Uma amabhawodi axhumayo ekhanda lesilinda engaqiniswa enanini le-torque elishiwo, ukuguga kwe-cylinder head gasket okubangelwa yilokhu kugxuma okuncane kuzokwenzeka ngokushesha nakakhudlwana. Uma i-bolt yokuxhuma ikhululekile kakhulu, izobangela inani lokuphuma kwekhanda le-cylinder elihlobene ne-cylinder block. Uma i-bolt yokuxhuma iqiniswe ngokweqile, ukucindezeleka kwebhawodi yokuxhuma kuzodlula umkhawulo wamandla okukhiqiza, okuholela ekwandiseni ibhowudi yokuxhuma kudlule ukubekezelelana komklamo wayo, okuzophinde kubangele ukugxuma kwekhanda le-cylinder kwanda Ukusheshisa ukugqoka kwe-cylinder head gasket.

4. Ukucaba kwekhanda le-cylinder noma i-cylinder block kukhulu kakhulu

I-Warpage kanye nokuhlanekezela yizinkinga ezivamile emakhanda e-cylinder kanye nembangela eyinhloko yokushiswa okuphindaphindiwe kwama-cylinder head gaskets. Ikakhulukazi, ikhanda le-aluminium alloy cylinder lisebenza ngokugqamile, ngoba i-aluminium alloy material ine-high heat yokudlulisa ukushisa, futhi ikhanda le-cylinder lincane futhi lincane kune-cylinder block, futhi izinga lokushisa kwekhanda le-aluminium alloy cylinder likhuphuka ngokushesha. Lapho ikhanda le-cylinder likhubazekile, ukusebenzisana kwayo okuhleliwe ne-cylinder block kuzoba nzima kakhulu, futhi ikhwalithi yokuvala isilinda izokwehla, kubangele ukuvuza komoya futhi kushise i-cylinder gasket, ngaleyo ndlela kuqhubeke konakala ikhwalithi yokuvala yesilinda.
