No nā ʻenekini inikini carburetor a i ʻole ke kino throttle, ʻo ka manifold intake e pili ana i ka laina intake mai hope o ke carburetor a i ʻole ke kino throttle a i mua o ka intake poʻo cylinder. ʻO kāna hana ka hoʻolaha ʻana i ka hui ʻana o ka ea a me ka wahie i kēlā me kēia puka intake cylinder e ka carburetor a i ʻole ke kino throttle.
No nā ʻenekini hoʻokomo wahie ea a i ʻole nā ʻenekini diesel, hāʻawi wale ka manifold intake i ka ea maʻemaʻe i kēlā me kēia intake cylinder. Pono ka manifold intake e hāʻawi like i ka ea, ka hui wahie a i ʻole ka ea maʻemaʻe i kēlā me kēia cylinder. No kēia kumu, pono e like ka lōʻihi o ke ala o ke kinoea i loko o ka manifold intake. I mea e hōʻemi ai i ke kū'ē ʻana o ke kahe kinoea a hoʻomaikaʻi i ka hiki ke intake, pono e laumania ka paia o loko o ka manifold intake.
Ma mua o ko kākou kamaʻilio ʻana e pili ana i ka manifold intake, e noʻonoʻo kākou pehea e komo ai ka ea i loko o ka ʻenekini. Ma ka hoʻolauna ʻana i ka ʻenekini, ua ʻōlelo mākou i ka hana o ka piston i loko o ka cylinder. Ke komo ka ʻenekini i ka stroke intake, neʻe ka piston i lalo e hana i kahi vacuum i loko o ka cylinder (ʻo ia hoʻi, e liʻiliʻi ke kaomi), i hiki ai ke hana ʻia ka ʻokoʻa o ke kaomi ma waena o ka piston a me ka ea o waho, i hiki ai i ka ea ke komo i loko o ka cylinder. No ka laʻana, ua hāʻawi ʻia iā ʻoukou a pau kahi injection, a ua ʻike ʻoukou i ke ʻano o ka omo ʻana o ke kahu maʻi i ka lāʻau lapaʻau i loko o ka syringe. Inā ʻo ka barela nila ka ʻenekini, a laila i ka wā e huki ʻia ai ka piston i loko o ka barela nila, e omo ʻia ka potion i loko o ka barela nila, a na ka ʻenekini e huki i ka ea i loko o ka cylinder.
Ma muli o ke ana wela haʻahaʻa o ka hopena intake, ua lilo ka mea composite i mea kaulana i ka manifold intake. He māmā kona kaumaha i loko, hiki ke hoʻemi pono i ke kū'ē a hoʻonui i ka pono o ka intake.
