Babban ayyukan toshe silinda sun haɗa da:
- A matsayin tushen haɗa dukkan sassan injin, yana ɗauke da ramukan silinda (inda pistons ke motsawa baya da gaba), jaket ɗin ruwa masu sanyaya (don jagorantar zagayawar sanyaya don watsa zafi), da hanyoyin mai (don shafa mai a muhimman sassan). Hakanan yana aiki tare da kan silinda don samar da ɗakin ƙonewa, wanda ke jure yanayin zafi da matsin lamba mai yawa kuma yana shiga cikin canza kuzarin zafi daga ƙonewar mai zuwa makamashin inji.
- Dangane da kayan aiki da tsari, tubalin silinda yawanci ana yin sa ne da ƙarfe ko ƙarfe na aluminum - tubalan ƙarfe na siminti suna da fa'idodi kamar ƙarfi mai yawa, juriya ga matsin lamba mai yawa da zafin jiki mai yawa, da ƙarancin farashi, wanda hakan ya sa suka dace da samfuran da ke fifita kwanciyar hankali; tubalan ƙarfe na aluminum suna da sauƙi, suna taimakawa wajen adana kuzari, amma suna da ƙarancin juriyar lalacewa kuma galibi suna buƙatar layukan silinda, kuma ana amfani da su sosai a ƙananan motoci. A tsarin gini, tubalin silinda na iya zama nau'ikan layi madaidaiciya, siffa ta V, ko nau'ikan da ke adawa da juna a kwance, waɗanda ke shafar daidaito kai tsaye, fitarwar wutar lantarki, da sarrafa abin hawa na injin.
