Cylinder ndicho chinhu chikuru chekumanikidza vhoriyamu. Zvinodikanwa zvesilinda: simba rakaringana, kuomarara uye kuramba kupfeka; Mamiriro akanaka ekutonhora; Diki kuyerera kuramba (yakakura zvakakwana mweya inoyerera chiteshi nzvimbo uye yemhepo vharuvhu yekuisa nzvimbo); Deredza iyo clearance vhoriyamu; Zvinonzwisisika kuwedzera vhoriyamu yevhavha yekamuri uye kudzikisa mweya kuyerera kumanikidza kupomba. General zvinhu: simbi yakakandwa.    

Iyo cylinder inoumbwa nemhepo vharuvhu kamuri, yemvura mugero, humburumbira chivhariso, humburumbira musoro, nezvimwewo ikoko kazhinji hakuna humburumbira liner. Zvinoenderana nemaitiro ekuita, pane matatu mafomati mafomu: imwechete yekuita mhando, mbiri yekuita mhando uye musiyano mhando; Zvinoenderana nemamiriro ekutonhora, pane kutonhorera kwemhepo uye kutonhora kwemvura.  

Kurongeka musimboti wevharuvhu yemhepo pane humburumbira: iyo yekumisikidza nzvimbo yevhavha yemhepo yakakura, ndiko kuti, kuyerera kwemhepo chiteshi nzvimbo yakakura, kurasikirwa kwekudzivirira idiki, kuisirwa uye kugadzirisa zviri nyore, uye clearance vhoriyamu idiki.  

. simba rinoita pisitoni uye nekuvandudza iko kushanda kwesirinda. Hupfumi hwemakomputa makuru uye epakati ari kushanda achienderera kwenguva yakareba akakosha, saka nhanho dzinosarudzwa zvinoenderana neepamusoro pekugona poindi, uye inoenderana compression ratio pamatanho ese ari pakati pe 2-4. Iyo cylinder uye pisitoni gungano inoenderana nechero tsvimbo yekubatanidza inonzi ikholamu.Kushandiswa kwemazhinji column compression kunogona kuenzanisa kudzosera inertia simba re compressor zvakakwana kana kunyanya, kurerutsa chimiro chekoramu imwe neimwe uye zvinoderedza huwandu hwakawanda hwegesi mukoramu. Zvisinei, kuwedzera kwenhamba yemakoramu kuchanetsa chimiro checompressor uye wedzera huwandu hwenzvimbo uye zvikamu.
