Udonga lwangaphandle lwe-liner ye-cylinder emanzi lunxibelelana ngokuthe ngqo kunye nesipholisi, ubukhulu bodonga buyi-5 ~ 8mm, ukubekwa kwe-radial kuphunyezwa ngokusebenzisa umsesane wokumisa ongasentla nasezantsi, kunye nokuma kwe-axial kuphunyezwa ngokuthelekisa i-flange ephezulu. i-cylinder liner eneendawo ezixhasayo ezihambelanayo phezulu emzimbeni. Iingenelo ze-liner ye-cylinder emanzi kukuba akukho bhatyi yamanzi evaliweyo emzimbeni, kulula ukuphosa, ukuhanjiswa kobushushu obuhle, ukusabalalisa ubushushu obufanayo, ukulungiswa lula, kunye ne-cylinder liner inokutshintshwa ngaphandle kokususa injini kwimoto. Ukungalungi kukuba ubunzima bomzimba buhluphekile kwaye kulula ukuvuza.Ubuso obungaphakathi be-cylinder bulula ukugqoka ngenxa yesenzo sokushisa okuphezulu kunye noxinzelelo oluphezulu lwegesi kunye nokudibanisa nepiston ehambayo ehamba phambili. Ukuze kuphuculwe ukunyanzeliswa kokugqoka kwe-cylinder kunye nokwandisa ubomi benkonzo ye-cylinder, kukho iifom ezahlukeneyo zesakhiwo se-cylinder kunye neendlela zokunyanga komhlaba. Kukho iintlobo ezintathu zesakhiwo se-cylinder: akukho luhlobo lwe-cylinder liner, uhlobo lwe-cylinder eyomileyo, uhlobo olumanzi lwe-cylinder liner.
