Kwiinjini ze-carburetor okanye i-throttle body, i-incase manifold ibhekisa kumgca wokungenisa ovela ngasemva kwe-carburetor okanye i-throttle body ukuya ngaphambi kokungenisa intloko yesilinda. Umsebenzi wayo kukusasaza umxube womoya kunye namafutha kwizibuko ngalinye lokungenisa isilinda nge-carburetor okanye i-throttle body.
Kwiinjini zokungenisa amafutha emoyeni okanye kwiinjini zedizili, i-incase manifold isasaza umoya ococekileyo kwi-incase yesilinda nganye. I-incase manifold kufuneka isasaze umoya, umxube we-fuel okanye umoya ococekileyo ngokulinganayo kwi-incase nganye. Ngenxa yesi sizathu, ubude bendlela yokudlula kwegesi kwi-incase manifold kufuneka bulingane kangangoko. Ukuze kuncitshiswe ukumelana nokuhamba kwegesi kwaye kuphuculwe umthamo wokungenisa, udonga lwangaphakathi lwe-incase manifold kufuneka lube bushelelezi.
Ngaphambi kokuba sithethe nge-input manifold, makhe sicinge ngendlela umoya ongena ngayo enjinini. Kwintshayelelo yenjini, sikhankanye ukusebenza kwepiston kwisilinda. Xa injini ikwi-intake stroke, i-piston iyehla ukuze ivelise i-vacuum kwisilinda (oko kukuthi, uxinzelelo luba ncinci), ukuze kubekho umahluko woxinzelelo phakathi kwepiston nomoya wangaphandle, ukuze umoya ungene kwisilinda. Umzekelo, nonke ninikwe inaliti, kwaye niyibonile indlela umongikazi afunxe ngayo iyeza kwisirinji. Ukuba i-needle barrel yinjini, xa i-piston engaphakathi kwi-needle barrel ikhutshwa, i-potion iya kufunxwa kwi-needle barrel, kwaye injini izakutsala umoya kwisilinda.
Ngenxa yobushushu obuphantsi besiphelo sokungenisa, izinto ezidityanisiweyo ziye zaba yinto ethandwayo yokungenisa izinto ezininzi. Ubunzima bazo obulula buthambile ngaphakathi, nto leyo enokunciphisa ngempumelelo ukumelana nokunyuka nokusebenza kakuhle kokungenisa.
