Mkati mwazitsulo za silinda zimakhudzidwa mwachindunji ndi kutentha kwakukulu ndi mpweya wothamanga kwambiri, ndipo nthawi zonse zimakhala zothamanga kwambiri zothamanga ndi mphete ya pistoni ndi siketi ya pistoni.Kumwamba kumakhudzana ndi madzi ozizira, zomwe zimapangitsa kuti pakhale kutentha kwakukulu kwa kutentha pansi pa kusiyana kwakukulu kwa kutentha, ndipo kumawonongeka ndi madzi ozizira.Kuponyedwa m'mbali kwa pisitoni pa cylinder liner sikumangowonjezera kukangana kwake kwamkati, komanso kumapangitsa kuti ipindike.Pistoni imagundanso cylinder liner pomwe mbali yake ikusintha komwe akupita.Komanso, ndi pansi lalikulu unsembe preload.
Kuthamanga kwa gasi kumapangitsa kuti pakhale kupanikizika kwapang'onopang'ono komanso kupanikizika kwa ma radial pakhoma la silinda, ndipo ndi yaikulu kwambiri mkati, zonse zomwe zimakhala zothamanga kwambiri.
Chifukwa cha kupsyinjika kwakukulu kwa kutentha komwe kumachitika chifukwa cha kusiyana kwa kutentha pakati pa mkati ndi kunja kwa khoma la silinda, kupanikizika kwapakati kumachitika pamtunda wamkati ndipo kupanikizika kwapakati kumakhalapo pamtunda wozizira pansi pa kutentha kwabwino.Komabe, pansi pa kutentha kwambiri, zitsulo zomwe zili pafupi ndi mkati zimatha kusinthidwa ndi pulasitiki, ndipo pambuyo pozizira, kupanikizika kotsalira kumapangidwira mkati.Kupsinjika kwapang'onopang'ono kumeneku komwe kumachitika chifukwa choyamba ndi kuyimitsa kusintha kumayambitsa kutopa kwakuthupi.
Chovala cha silinda chiyenera kukhala ndi mphamvu zokwanira, kulimba ndi kukana kutentha, komanso kukana kuvala bwino.Payenera kukhala mafuta abwino ndi kuziziritsa panthawi ya ntchito.
Silinda ya silinda nthawi zambiri imapangidwa ndi chitsulo chosagwira ntchito cha aloyi chokhala ndi phosphorous kapena boron, monga HT25-47, HP-CuCrMo, ndi zina zotero. chrome plating pa malo osungira mafuta), nitriding kapena phosphating kuti apititse patsogolo kukana kuvala.Kulimba kwamkati kwapakati pa silinda ya silinda nthawi zambiri kumafunika kukhala kwakukulu kuposa HB200, ndipo kumafanana bwino ndi kuuma kwa mphete ya pistoni.Pakatikati pake payeneranso kukhala ndi roughness yoyenera, kuti ikhale ndi mphamvu yosungiramo mafuta ndikugwira ntchito.Pamwamba pakatikati payenera kukhala ndi kuzungulira kokwanira ndi kulondola kwa cylindricity, ndipo chothandizira chokwera chomwe chikuyang'ana pakati pa dzenje lamkati chiyenera kukhala cholondola kwambiri.
