FSI (Volkswagen) engine - he aha ke 'ano o ka engine, 'ano

ʻO ka ʻenekini FSI ʻo ia ka ʻōnaehana hou loa a me ke kaiapuni, ʻoi aku ka maikaʻi o kā mākou ʻike ma ke ʻano he injection pololei. Ua hoʻomohala ʻia kēia ʻōnaehana i nā makahiki 2000 mua e Volkswagen a hoʻohana ʻia i nā kaʻa Audi. Ua hana pū nā mea hana kaʻa ʻē aʻe i kā lākou hoʻomohala ʻana ma kēia ʻaoʻao, a ua hoʻohana ʻia nā pōkole ʻē aʻe no kā lākou mau mīkini:

Renault - IDE;
Alfa Romeo - JTS;
Mercedes - CGI;
Mitsubishi – GDI;
Ford - EcoBoost a pēlā aku.

Akā ua kūkulu ʻia kēia mau ʻenekini a pau ma ke kumu like.

ʻO nā hiʻohiʻona o kēia ʻano mīkini penei:

ka loaʻa ʻana o ʻelua mau hiʻohiʻona kahe wahie - nā kaapuni haʻahaʻa a kiʻekiʻe;
ʻO kahi pauma wahie i hoʻokomo pono ʻia i loko o ka pahu e hoʻoheheʻe i ka ʻaila i loko o ka ʻōnaehana ma kahi kaomi o 0,5 MPa, e hoʻomalu ʻia ka hana o ka pamu e ka mana mana;
ʻO ka pauma wahie e pāpaʻi wale i ka nui o ka wahie i ana ʻia, helu ʻia kēia nui e ka mana hoʻokele e pili ana i ka ʻikepili mai nā ʻano mea ʻike like ʻole, ʻo nā pulupulu e komo ana i ka pauma e hana me ka ikaika a ʻoi aʻe paha.

ʻO ke kaapuni kiʻekiʻe ke kuleana no ka hāʻawi ʻana i ka pahu cylinder me ka wahie. Hoʻomoʻi ʻia ka ʻaila i loko o ke kaʻaahi e kahi pamu kiʻekiʻe. ʻO ke kaomi i loko o ka ʻōnaehana ma aneʻi hiki i kahi hōʻailona o 10-11 MPa. ʻO ka ramp he paipu hoʻoheheʻe wahie me nā nozzles ma nā wēlau, kēlā me kēia nozzle ma lalo o ke kaomi nui e hoʻokomo pololei i ka nui o ka ʻaila i loko o nā keʻena puhi ahi o nā pistons. Hoʻohui ʻia ka ʻaila me ka ea i loko o ke keʻena kuni, ʻaʻole i loko o ka intake manifold, e like me ka carburetor kahiko a me nā ʻenekini injection. I loko o ka pahu cylinder, pahū ka hui ʻana o ka ea-wahie ma lalo o ka hana o ke kaomi kiʻekiʻe a me kahi huna ahi, a hoʻonohonoho i nā pistons i ka neʻe.

ʻO nā mea koʻikoʻi o ke kaapuni piʻi kiʻekiʻe:

wahie kaomi regulator - hāʻawi ia i kahi kūpono kūpono o ka ʻaila;
palekana a me nā kīwaha bypass - ʻae lākou iā ʻoe e pale i ka piʻi nui ʻana o ke kaomi i loko o ka ʻōnaehana, hiki ke hoʻokuʻu ʻia ma ka hoʻokuʻu ʻana i ke kinoea nui a i ʻole ka wahie mai ka ʻōnaehana;
mīkini paʻi - e ana i ke kiʻekiʻe o ke kaomi i loko o ka ʻōnaehana a hānai i kēia ʻike i ka ʻāpana mana.

E like me kāu e ʻike ai, mahalo i kēlā ʻano ʻōnaehana o ka hāmeʻa, ua hiki ke mālama nui i ka nui o ka ʻaila i pau. Eia nō naʻe, no ka hana i hoʻonohonoho maikaʻi ʻia, pono e hana i nā polokalamu hoʻokele paʻakikī a hoʻokomo i ke kaʻa me nā ʻano ʻike like ʻole. ʻO nā hemahema i ka hana o ka ʻāpana hoʻomalu a i ʻole kekahi o nā mea ʻike hiki ke alakaʻi i nā kūlana i ʻike ʻole ʻia.

Eia kekahi, ʻoi aku ka maʻalahi o nā mīkini injection pololei i ka maikaʻi o ka hoʻomaʻemaʻe wahie, no laila ua kau ʻia nā koi kiʻekiʻe ma luna o nā kānana wahie, pono e hoʻololi ʻia e like me nā ʻōlelo aʻoaʻo ma ka manual kaʻa.

He mea nui nō hoʻi e hāʻawi ʻia nā ʻenekini i ka pau ʻana o ka wahie, ʻo ia hoʻi, ʻo ka liʻiliʻi o nā mea ʻino i hoʻokuʻu ʻia i ka lewa me nā kinoea pau. Mahalo i ia mau mea i hana ʻia, hiki ke hoʻomaikaʻi nui i ke kūlana kaiaola ma nā ʻāina o ʻEulopa, ʻAmelika ʻAmelika a me Asia Hema.

Ma kēia wikiō e ʻike ʻoe a lohe i ke ʻano o ka hana ʻana o kahi mīkini FSI mahana 2-lita me ka holo o 100 tausani km.
