I-cylinder pad, eyaziwa nangokuthi i-cylinder liner, itholakala phakathi kwekhanda lesilinda kanye ne-cylinder block. Umsebenzi wayo ukugcwalisa ama-pores microscopic phakathi kwekhanda lesilinda kanye nekhanda lesilinda, ukuqinisekisa ukubekwa uphawu okuhle endaweni ehlanganyelwe, bese uqinisekisa ukubekwa uphawu kwegumbi lokuvutha, ukuvikela ukuvuza kwamanzi ngentshiseko. Ngokuya ngezinto ezahlukahlukene, ama-gaskets amasilinda angahlukaniswa ngensimbi - ama-gaskets we-asbestos, insimbi - ama-gaskets ahlanganisiwe nawo wonke ama-gaskets ensimbi. I-cylinder pad iluphawu phakathi kwesihloko somzimba naphansi kwekhanda lesilinda. Indima yayo ukugcina uphawu lwesilinda aluvuza, gcina okupholile futhi uwoyela ugeleza emzimbeni uye ekhanda lesilinda awavuzi. I-cylinder pad inengcindezi ebangelwa ukuqinisa i-cylinder head bolt, futhi ifakwa ngaphansi kokushisa okuphezulu kanye nengcindezi ephezulu yegesi yokuvutha ku-cylinder, kanye nokugqwala kwamafutha nokuphola.
UGaspad uyakuba namandla anele futhi uyakumelana nenjabulo, ukushisa nokugqwala. Ngaphezu kwalokho, inani elithile lobuqili liyadingeka ukunxephezela ubulukhuni nokungalingani kwendawo ephezulu yomzimba kanye nekhanda eliphansi lekhanda lesilinda, kanye nodoti wekhanda lesilinda lapho injini isebenza
