Injini idinga ukumunca umoya omningi ngesikhathi sokusebenza. Uma umoya ungahlungiwe, uthuli olulengiswe emoyeni luzomuncwa kusilinda, okuzosheshisa ukugqokwa kweqembu le-piston nesilinda. Izinhlayiya ezinkulu ezingena phakathi kwepiston nesilinda zingabangela "ukudonsa isilinda", okuyinto ebucayi ikakhulukazi ezindaweni zokusebenza ezomile nezinesihlabathi. Isihlungi somoya sifakwe phambi kwe-carburetor noma ipayipi lokungenisa ukuze kuhlungwe uthuli nesihlabathi emoyeni, ukuqinisekisa ukuthi umoya owanele nohlanzekile ungena kusilinda.
Ngokwesimiso sokuhlunga, izihlungi zomoya zingahlukaniswa zibe uhlobo lwesihlungi, uhlobo lwe-centrifugal, uhlobo lokugeza uwoyela kanye nohlobo oluyinhlanganisela.
Ngesikhathi sokulungiswa, isici sokuhlunga iphepha akufanele sihlanzwe emafutheni, ngaphandle kwalokho isici sokuhlunga iphepha sizohluleka, futhi kulula ukudala ingozi esheshayo. Ngesikhathi sokulungiswa, indlela yokudlidliza kuphela, indlela yokususa ibhulashi elithambile (ukuxubha eduze kombimbi) noma indlela yokubuyisela umoya ocindezelwe ingasetshenziswa kuphela ukususa uthuli nokungcola okunamathiselwe endaweni yesihlungi sephepha. Ngengxenye yesihlungi esimahhadla, uthuli olusengxenyeni eqoqa uthuli, izindwani kanye nepayipi le-cyclone kufanele kususwe ngesikhathi. Ngisho noma ingagcinwa ngokucophelela ngaso sonke isikhathi, isici sokuhlunga iphepha asikwazi ukubuyisela ngokugcwele ukusebenza kwayo kwasekuqaleni, futhi ukumelana nokungena komoya kuzokwanda. Ngakho-ke, ngokuvamile, lapho isici sesihlungi sephepha sidinga ukugcinwa okwesine, kufanele sishintshwe into entsha yokuhlunga. Uma isici sesihlungi sephepha siqhekekile, sinezimbobo, noma isihlungi sephepha kanye nesivalo sokuphela sisusiwe, kufanele kushintshwe ngokushesha.
