Kwi-carburetor okanye i-throttle body injection ye-injini yepetroli, i-manifold intake ibhekisa kumgca wokuthatha ukusuka emva kwe-carburetor okanye umzimba we-throttle ukuya ngaphambi kokuthatha intloko yesilinda. Umsebenzi wayo kukusasaza umoya kunye nomxube wamafutha kwi-cylinder nganye yokuthatha i-port nge-carburetor okanye i-throttle body.
Kwii-injini ze-injini yamafutha omoya okanye ii-injini ze-diesel, i-manifold intake isasaza umoya ococekileyo kwi-cylinder nganye. Ubuninzi bokuthatha kufuneka busasaze umoya, umxube wamafutha okanye umoya ococekileyo ngokulungeleleneyo kangangoko kunokwenzeka kwisilinda ngasinye. Ngenxa yale njongo, ubude bomzila wegesi kwi-manifold intake kufuneka bulingane ngokusemandleni. Ukuze kuncitshiswe ukuxhathisa kokuhamba kwegesi kunye nokuphucula umthamo wokungena, udonga lwangaphakathi lwe-manifold yokuthatha kufuneka lube lula.
Ngaphambi kokuba sithethe ngobuninzi bokuthatha, makhe sicinge ngendlela umoya ongena ngayo enjinini. Kwintshayelelo ye-injini, sikhankanye ukusebenza kwepiston kwi-cylinder. Xa i-injini ikwi-stroke yokuthatha, i-piston ihlehla ukuze ivelise i-vacuum kwi-cylinder (oko kukuthi, uxinzelelo luba luncinci), ukwenzela ukuba umahluko woxinzelelo phakathi kwepiston kunye nomoya wangaphandle unokwenziwa, ukuze umoya ungene kwi-cylinder. Umzekelo, nonke ninikwe inaliti, kwaye niyibonile indlela umongikazi alifunxa ngayo iyeza kwisirinji. Ukuba umgqomo yenaliti yi-injini, ngoko xa ipiston ngaphakathi kwingqayi yenaliti ikhutshiwe, i-potion iya kutsalwa kwi-naliti yenaliti, kwaye injini iya kutsala umoya kwi-cylinder.
Ngenxa yobushushu obuphantsi besiphelo sokuthatha, imathiriyeli edibeneyo iye yaba yinto ethandwayo yokuthatha izinto ezininzi. Ubunzima bayo obulula bulula ngaphakathi, obunokunciphisa ngokufanelekileyo ukuchasana kunye nokwandisa ukusebenza kakuhle kokuthatha.
