Cylinder Pad, uzwi kandi nka silinderi liner, iherereye hagati yumutwe wa silinderi umutwe hamwe na silinderi. Igikorwa cyacyo nukuzuza ibisuguti bya microscopique hagati yumutwe wa silinderi n'umutwe mwiza, kugirango urebe ko kashe nziza, hanyuma urebe ikimenyetso cyurugereko rwo gutwika, gukumira akazu k'amazi. Dukurikije ibikoresho bitandukanye, gaskeri ya silinderi irashobora kugabanywamo icyuma - gaskekes ya asibesitosi, icyuma - ibyuma byose hamwe na gasket zose. Cylinder Pad ni kashe hagati yumubiri no hepfo yumutwe wa silinderi. Uruhare rwayo ni ugukomeza kashe ya silinderi ntabwo imeneka, komeza amavuta akonje namavuta ava mumubiri kugeza kumutwe wa silinderi ntutemba. Cylinder Pad ifite igitutu cyatewe no gukomera kumutwe wa silinderi, kandi ikorerwa ubushyuhe bwinshi kandi igitutu kinini cya gaze yo gutwika muri silinderi na coolant.
Gaspad igomba kuba imbaraga zihagije kandi izarwanya umunezero, ubushyuhe n'imbaho. Byongeye kandi, umubare runaka wa elastique urakenewe kugirango yishyure ubuso bwubuso bwumubiri nubuso bwumubiri no hasi bwumutwe wa silinderi, kimwe no guhindura silinderi umutwe mugihe moteri ikora
