Kuma-injini okufaka uphethiloli e-carburetor noma e-throttle body, i-input manifold ibhekisela emgqeni wokungenisa ovela ngemuva kwe-carburetor noma umzimba we-throttle kuze kube ngaphambi kokungenisa ikhanda lesilinda. Umsebenzi wayo ukusabalalisa ingxube yomoya kanye nophethiloli echwebeni ngalinye lokungenisa lesilinda nge-carburetor noma umzimba we-throttle.
Ezinjinini zokujova uphethiloli emoyeni noma ezinjinini zedizili, i-incase manifold imane isabalalise umoya ohlanzekile ku-incase ngayinye yesilinda. I-incase manifold kumele isabalalise umoya, ingxube kaphethiloli noma umoya ohlanzekile ngokulinganayo ngangokunokwenzeka ku-incase ngayinye. Ngale njongo, ubude bokudlula kwegesi ku-incase manifold kufanele bulingane ngangokunokwenzeka. Ukuze kuncishiswe ukumelana nokugeleza kwegesi futhi kuthuthukiswe umthamo wokungenisa, udonga lwangaphakathi lwe-incase manifold kufanele lube bushelelezi.
Ngaphambi kokuba sikhulume nge-input manifold, ake sicabange ngendlela umoya ongena ngayo enjinini. Esethulweni senjini, sikhulume ngokusebenza kwe-piston esilinda. Uma injini isesimweni sokucindezela i-intake, i-piston iyehla ukuze ikhiqize i-vacuum esilinda (okungukuthi, ingcindezi iba ncane), ukuze kukhiqizwe umehluko wokucindezela phakathi kwe-piston nomoya wangaphandle, ukuze umoya ungene esilinda. Isibonelo, nonke ninikezwe umjovo, futhi nibonile ukuthi umhlengikazi wamunca kanjani umuthi esirinji. Uma i-nail barrel iyinjini, khona-ke lapho i-piston engaphakathi kwesilinda senaliti ikhishwa, i-potion izomuncwa esilinjini senaliti, futhi injini izodonsa umoya esilinda.
Ngenxa yokushisa okuphansi kokuphela kokungenisa, izinto ezihlanganisiwe seziyinto ethandwayo yokungenisa izinto eziningi. Isisindo sayo esilula sibushelelezi ngaphakathi, okunganciphisa ngempumelelo ukumelana nokudla futhi kwandise ukusebenza kahle kokungenisa.
