ʻO GDI ka wā e hiki mai ana?

ʻO kekahi o nā mea hiki ke hoʻomaikaʻi i ka pono o ka mīkini ʻo ia ka hoʻonui ʻana i ke kaʻina hana o ka puhi ʻana o ka hui ʻana i nā cylinders.

ʻO kekahi o nā kuhikuhi o ka hoʻomaikaʻi ʻana i ka pono o ka ʻenekini hoʻopau i loko ka hana ma ka hoʻonui ʻana i ke kaʻina o ke kaʻina puhi ʻana i loko o nā cylinders.

ʻO ke ala e hoʻokō ai i kēia pahuhopu, ʻo ia ka hoʻomākaukau pololei ʻana o ka hui ʻana me ka hoʻohana ʻana i ka ʻaila ʻaila i loko o nā cylinders ma lalo o ke kaomi kiʻekiʻe GDI / Gasoline Direct Injection /. ʻO ka maikaʻi ʻole o kēia ʻenekini he 20 pakeneka haʻahaʻa haʻahaʻa.

Loaʻa ka hoʻohana ʻana i ka wahie haʻahaʻa ma ke puhi ʻana i kahi hui lean. Hiki ke ho'āla ʻia o ia ʻano hui ʻana ma muli o ke ʻano kūikawā o ke keʻena puhi ahi. Hana ʻia kahi ʻāpana o kahi hui ʻoi aku ka maikaʻi a hiki ke hoʻā ʻia ma kahi kokoke i ka pahu hunaahi, kahi e laha ai ka lapalapa i nā wahi o ka hui lean. Ke koi ʻia ka mana piha, puhi ka ʻenekini i kahi hui stoichiometric.

Ke hoʻohālikelike ʻia me nā ʻenekini maʻamau, loaʻa i nā ʻenekini GDI kekahi pono ʻē aʻe. ʻO ia ka hoʻemi ʻana o ka carbon dioxide a me ka haʻahaʻa haʻahaʻa o nā nitrogen oxides i ka wā e hana ai ka mīkini me nā haʻahaʻa hapa.
