E like me kāu e ʻike ai, nui nā kini hopu ʻaila i loaʻa ma ka mākeke a ʻoi aku ka maikaʻi o kekahi mau huahana ma mua o nā mea ʻē aʻe. Ma mua o ke kūʻai ʻana i kahi pahu aila, eia kekahi mau mea nui e noʻonoʻo ai:

Nui

I ke koho ʻana i ka nui kūpono o ka aila hopu hiki no kāu kaʻa, ʻelua mau mea nui e noʻonoʻo ai - ʻehia nā cylinders i loko o ka ʻenekini, a he ʻōnaehana turbo ke kaʻa?
Pono nā kaʻa ma waena o 8 a me 10 cylinders i kahi pahu aila nui. Inā he 4 - 6 mau pahu wale nō kāu kaʻa, pono e lawa ka nui o ka aila hopu. Eia nō naʻe, inā loaʻa iā ʻoe he 4 a hiki i ka 6 cylinders akā loaʻa iā ʻoe kahi ʻōnaehana turbo, pono paha ʻoe i kahi pahu hopu aila nui, e like me kāu e hoʻohana ai i ke kaʻa me nā pahu ʻoi aku. ʻOi aku ka maikaʻi o nā kini nui no ka mea hiki iā lākou ke paʻa i ka ʻaila ʻoi aku ka nui ma mua o nā kini liʻiliʻi. Eia nō naʻe, hiki ke paʻakikī i ka hoʻokomo ʻana i nā kini ʻaila nui a paʻakikī paha, e lawe ana i nā wahi makamae ma lalo o ka puʻu.

Hoʻokahi a ʻelua paha valve

Loaʻa nā pahu ʻaila hopu hoʻokahi a me ʻelua ma ka mākeke. ʻOi aku ka maikaʻi o ka pahu hopu pahu pālua ʻelua no ka mea hiki ke loaʻa i ʻelua mau pilina waho, hoʻokahi ma ka intake manifold a ʻo kekahi ma ka ʻōmole throttle.
Ma ka loaʻa ʻana o ʻelua mau hoʻokuʻi ʻana i waho, hiki ke hoʻohana ʻia ka pahu hopu ʻaila ʻelua i ka wā e hana ʻole ai ke kaʻa a me ka wikiwiki, e ʻoi aku ka maikaʻi no ka mea hiki iā ia ke hoʻomaʻemaʻe i nā mea haumia a puni ka mīkini.
ʻAʻole e like me ka ʻaila ʻaila hopu ʻelua, ʻo ka koho valve hoʻokahi wale nō ke awa ma waho o ka valve intake, ʻo ia hoʻi, ʻaʻohe haumia ma hope o ka kānana ʻia ʻana o ka ʻōmole throttle.

Kānana

Hiki ke hana i ka aila ma ke kānana ʻana i ka ʻaila, ka mahu wai, a me ka wahie i puhi ʻole ʻia i ka lewa e hoʻopuni ana a puni ka ʻōnaehana hoʻoheheʻe crankcase. No ka hana pono o ka aila, pono e hoʻokomo i kahi kānana i loko.
E kūʻai aku ana kekahi mau hui i nā kini hopu ʻaila me ka kānana ʻole, ʻaʻole pono kēia mau huahana i ke kālā he mea ʻole. E hōʻoia i ka ʻaila i hiki iā ʻoe ke manaʻo e kūʻai e hele mai me kahi kānana i loko, ʻoi aku ka maikaʻi o ka baffle kūloko no ka hoʻokaʻawale ʻana i nā mea haumia a hoʻomaʻemaʻe i ka ea a me nā mahu.
