Intloko ye-cylinder ngokuqhelekileyo yenziwe nge-grey cast iron okanye i-alloy cast iron, kodwa ukuze kuphuculwe uqoqosho lwamafutha esithuthi, ubunzima be-injini busondele, kwaye ukusetyenziswa kwezinto ezikhanyayo kunokunciphisa ngokufanelekileyo umgangatho we-injini. Iinjini zokukhanya (iinjini zepetroli kunye neenjini zedizili ezinokufuduswa okungaphantsi kwe-3L) zisebenzisa ngokubanzi izinto ze-alloy kwiintloko ze-cylinder. Ngaphantsi kwesakhiwo esifanayo, xa kuthelekiswa nezixhobo zetsimbi, ubunzima bungancitshiswa nge-40% ukuya kwi-60%.

I-aluminium alloy ine-conductivity efanelekileyo ye-thermal, ukusebenza kakuhle kokupholisa, kwaye yinto egqwesileyo yesilinda. Ukongezwa kweCu kwi-aluminium alloy kunokuphucula ukuzinza kwe-thermal, kwaye ukongezwa kweMg kunokunyusa ubunzima bokuphosa.

Intloko ye-cylinder ifakwe kwi-cylinder block ukutywina i-cylinder ukusuka phezulu kwaye wenze igumbi lokutshisa. Ihlala idibanisa ne-high-temperature kunye ne-high-pressure gas, ngoko ithwala umthwalo omkhulu we-thermal kunye nomthwalo womatshini. Ijacket yamanzi okupholisa yenziwe ngaphakathi kwentloko ye-cylinder ye-injini epholileyo yamanzi, kwaye umngxuma wamanzi okupholisa ekupheleni kwentloko ye-cylinder unxibelelana nomngxuma wamanzi okupholisa webhloko yesilinda. Sebenzisa amanzi ajikelezayo ukupholisa iindawo zobushushu obuphezulu njengegumbi lokutsha.

Intloko ye-cylinder nayo ixhotyiswe kunye nezihlalo ze-valve zokungena kunye nokukhupha, imingxuma yesikhokelo sevalve yokufaka i-intake and exhaust valves, kunye nemigudu yokungena kunye nokukhupha. Intloko ye-cylinder ye-injini ye-petroli ifakwe imingxuma yokufakela iiplagi ze-spark, ngelixa intloko ye-cylinder ye-injini ye-diesel ifakwe imingxuma yokufakela ii-injector zamafutha. Intloko ye-cylinder ye-injini ye-camshaft engaphezulu iphinde isetyenziswe kunye nomngxuma wokuthwala i-camshaft yokufaka i-camshaft.
