ʻO ka hoʻokomo ʻia ʻana o nā geometry ʻokoʻa

No ka hana maikaʻi loa, pono e loaʻa i ka pahu komo o kahi kaʻa kahi geometry kikoʻī e hoʻohālikelike i ka wikiwiki ʻenekini kikoʻī. No kēia kumu, ʻo ka hoʻolālā maʻamau e hōʻoiaʻiʻo i ka hoʻouka pono ʻana o nā cylinders i loko o kahi palena palena ʻole o ka wikiwiki engine. No ka hōʻoia ʻana i ka lawa ʻana o ka ea i ke keʻena kuni i kēlā me kēia wikiwiki, hoʻohana ʻia kahi ʻōnaehana hoʻololi geometry intake manifold.

Pehea e hana ai ka Pūnaehana Manifold Geometry

I ka hoʻomaʻamaʻa, hiki ke hoʻololi i ka manifold intake ma nā ala ʻelua: ma ka hoʻololi ʻana i ka ʻāpana cross-sectional a me ka hoʻololi ʻana i kona lōʻihi. Hiki ke hoʻohana hoʻokahi a hui pū paha kēia mau ʻano.

Nā hiʻohiʻona o ka intake manifold me ka lōʻihi like ʻole

Variable Length Intake Manifold - Hoʻohana ʻia kēia ʻenehana i nā kaʻa petrol a me nā kaʻa diesel, me ka ʻole o nā ʻōnaehana supercharged. ʻO ke kumu o kēia hoʻolālā penei:

• Ma ka haʻahaʻa haʻahaʻa ma luna o ka ʻenekini, komo ka ea ma o kahi lālā ʻohi elongated.
• Ma ka wikiwiki engine kiʻekiʻe - ma ka lālā pōkole o ka ʻohi.
• Hoʻololi ʻia ke ʻano hana e ka ʻenekini ECU ma o kahi mea hoʻokele e hoʻokele i ka valve a laila e kuhikuhi i ka ea ma kahi ala pōkole a lōʻihi paha.

Hoʻokumu ʻia ka manifold intake lōʻihi i ka hopena o ka resonant boost a hāʻawi i kahi hoʻokomo ikaika o ka ea i loko o ke keʻena kuni. Hana ʻia kēia ma ke ʻano penei:

• Noho kekahi ea i loko o ka manifold ma hope o ka pani ʻia ʻana o nā kiwi komo.
• ʻO ka oscillation o ke koena ea i loko o ka manifold e like me ka lōʻihi o ka intake manifold a me ka wikiwiki engine.
• Ke hōʻea nā haʻalulu i ka resonance, hana ʻia ke kaomi kiʻekiʻe.
• Hāʻawi ʻia ka ea paʻa i ka wā e wehe ʻia ai ka valve intake.

ʻAʻole hoʻohana nā ʻenekini supercharged i kēia ʻano o ka intake manifold no ka mea ʻaʻohe pono e hana i ka hoʻoemi ʻana i ka ea. Hoʻokomo ʻia ka injection i loko o ia mau ʻōnaehana me ka hoʻohana ʻana i kahi turbocharger i kau ʻia.

Nā hiʻohiʻona o ka intake manifold me kahi ʻāpana hoʻololi

I ka ʻoihana kaʻa, hoʻohana ʻia ka intake manifold sizing i nā kaʻa ʻaila a me nā kaʻa diesel, me nā ʻōnaehana supercharged. ʻOi aku ka liʻiliʻi o ka ʻāpana keʻa o ka paipu i hoʻolako ʻia ai ka ea, ʻoi aku ka nui o ke kahe, a no laila ka hui ʻana o ka ea a me ka wahie. Ma kēia ʻōnaehana, loaʻa i kēlā me kēia cylinder nā awa hoʻokomo ʻelua, me kēlā me kēia me kāna valve intake ponoʻī. He damper kekahi o na auwai elua. Hoʻokele ʻia kēia ʻōnaehana hoʻololi geometry intake manifold e kahi kaʻa uila a i ʻole ka mea hoʻoponopono vacuum. ʻO ke kumu o ka hana o ka hale e like me kēia:

• Ke holo ka enekini i ka haʻahaʻa haʻahaʻa, aia nā dampers i ke kūlana pani.
• Ke wehe ʻia ka valve intake, komo ka hui ʻana o ka ea-wahie i ka cylinder ma hoʻokahi awa wale nō.
• I ka hele ʻana o ka ea ma ke kahawai, komo ʻo ia i ke keʻena ma ke ʻano spiral e hōʻoia i ka hui maikaʻi ʻana me ka wahie.
• Ke holo nei ka enekini i ka mama nui, wehe na mea hoopahee a kahe ka huila ea ma na ala elua, e hoonui ana i ka mana o ka enekini.

He aha nā hoʻolālā no ka hoʻololi ʻana i ka geometry e hoʻohana ʻia e nā mea hana

I ka ʻoihana kaʻa kaʻa honua, hoʻohana ʻia ka intake manifold geometry system e nā mea hana he nui e pili ana i kēia ʻenehana ma ko lākou inoa ponoʻī. No laila, hiki ke wehewehe ʻia nā hoʻolālā intake manifold lōʻihi e like me kēia:

• Ford ʻO ka inoa o ka ʻōnaehana ʻo Dual-Stage Intake;
• BMW ʻO ka inoa o ka ʻōnaehana ʻo Differential Variable Air Intake;
• Mazda.  ʻO ka inoa o ka ʻōnaehana ʻo VICS a i ʻole VRIS.

Hiki ke ʻike ʻia ke ʻano o ka hoʻololi ʻana i ka ʻāpana kea o ka intake manifold e like me:

• Ford ʻO ka inoa o ka ʻōnaehana ʻo IMRC a i ʻole CMCV;
• Opel. ʻO ka inoa o ka ʻōnaehana ʻo Twin Port;
• chinatown. ʻO ka inoa o ka ʻōnaehana ʻo Variable Intake System;
• Volvo ʻO ka inoa o ka ʻōnaehana ʻo Variable Induction System.

ʻO ka hoʻohana ʻana i kahi ʻōnaehana hoʻololi geometry, me ka nānā ʻole i ka hoʻololi ʻana i ka lōʻihi a i ʻole ka ʻāpana ʻāpana o ka intake manifold, hoʻomaikaʻi i ka hana o ke kaʻa, ʻoi aku ka waiwai a hoʻemi i ka neʻe ʻana o nā mea ʻawaʻawa i nā kinoea hoʻopau.
