Ku birebana na moteri zikoresha lisansi zikoresha kabureta cyangwa throttle body, intake manifold yerekeza ku murongo w’intake uhereye inyuma ya kabureta cyangwa throttle body kugeza mbere y’umutwe wa silindiri. Inshingano yayo ni ugukwirakwiza umwuka n’ibikomoka kuri lisansi kuri buri gice cy’intake ya silindiri hakoreshejwe kabureta cyangwa throttle body.
Ku moteri zikoresha lisansi mu nzira z'umwuka cyangwa moteri za mazutu, moteri itwara umwuka ikwirakwiza umwuka mwiza kuri buri cylinder itwara umwuka. Imoteri itwara umwuka igomba gukwirakwiza umwuka, imvange y'amavuta cyangwa umwuka mwiza ku buryo bungana uko bishoboka kose kuri buri cylinder. Kubera iyo mpamvu, uburebure bw'inzira ya gazi muri moteri itwara umwuka bugomba kuba bungana uko bishoboka kose. Kugira ngo igabanye ubushobozi bwo kwirinda gazi no kunoza ubushobozi bwo kwinjira, urukuta rw'imbere rwa moteri itwara umwuka rugomba kuba rworoshye.
Mbere yuko tuvuga ku intake manifold, reka dutekereze ku buryo umwuka winjira muri moteri. Mu ntangiriro ya moteri, twavuze imikorere ya piston muri silinda. Iyo moteri iri mu intake stroke, piston imanuka kugira ngo ikore vacuum muri silinda (ni ukuvuga ko umuvuduko uba muto), kugira ngo itandukaniro ry'umuvuduko hagati ya piston n'umwuka wo hanze rishobore kuboneka, kugira ngo umwuka ubashe kwinjira muri silinda. Urugero, mwese mwatewe inshinge, kandi mwabonye uburyo umuforomo yanyoye umuti muri syringe. Niba umuvuduko w'urushinge ari moteri, noneho piston iri mu muvuduko w'urushinge ikuwemo, umuti uzanyuzwa mu muvuduko w'urushinge, maze moteri ikurure umwuka muri silinda.
Bitewe n'ubushyuhe buke bw'igice cyo kwinjiramo, ibikoresho bivanze byahindutse ibikoresho bikunzwe cyane byo kwinjiramo. Uburemere bwabyo bworoheje imbere, bishobora kugabanya neza ubushobozi bwo kwirinda no kongera imikorere y'ibikoresho byo kwinjiramo.
