Pehea e hana ai ka ʻenekini BMW 50d tri-turbo diesel?

Inā he hui i ʻike ʻia nā ʻōnaehana twin-turbo ma ke ʻano he sequential a i ʻole like, pono e ʻike ʻia ka ʻaoʻao ʻenehana o ka BMW tri-turbo, kahi e hoʻohui iki ai i nā ʻenehana ʻelua. E ʻoluʻolu, inā ʻaʻole ʻoe manaʻo e pili ana i nā turbocharger, kono wau iā ʻoe e nānā maanei.

Pehea ka hana ʻana o kēia ʻenekini turbo ʻekolu?

ʻO ka mea mua, pono e hoʻomaopopo ʻia ʻo kēia ʻōnaehana supercharging ʻelua mau turbines liʻiliʻi (1 a me 3 ma ke kiʻikuhi) me ka geometry variable, a me kahi turbocharger maʻamau nui (2 ma ke kiʻi). Hoʻopili kēlā me kēia mea i kekahi mau wikiwiki, a laila ʻike mau ʻia lākou i nā ʻano kiʻekiʻe (maikaʻi, inā hiki iā ʻoe ke kapa iā ia i nā wikiwiki kiʻekiʻe, no ka mea ʻaʻole hele kiʻekiʻe nā diesel ...).

Ma nā haʻahaʻa haʻahaʻa, ma lalo o 1500 rpm, ua noi ʻia ka turbo mua (kekahi o nā geometry liʻiliʻi liʻiliʻi ʻelua) e ka exhaust (e hele mau ana ka ea hou mai waho mai i ka turbo nui). ʻOiai inā ʻaʻole ia e hana i kēia pae wikiwiki). A laila, e hoʻomaka ana ma 1500 rpm, hoʻomaka pū ka mea nui, no ka mea, ua lawa ke kahe o ka pau e hoʻonani ai. E hoʻomanaʻo ʻaʻole i hoʻāla pū ʻia nā turbines ʻekolu mai ka hoʻomaka ʻana o ke ʻano, no ka mea ma kēia hihia ʻaʻole nui ka hanu no ka hana o nā compressors ʻekolu. ʻO ka mea hope loa, ma 2500 rpm, hiki i ke kolu ke hoʻomaka e hana i ka hoʻomaikaʻi ʻana i ka wehe ʻana o ka damper (i kapa ʻia ʻo bypass), a laila hiki ke hāʻawi ʻia ke kinoea exhaust i kēia turbocharger (no ka mea ke hoʻomanaʻo nei au iā ʻoe ʻo ia ka ikehu e hiki ai iā ʻoe ke hoʻokele. ka enekini). ʻO turbo ka "makani" i hana ʻia e nā kinoea hoʻopau).

Mai ka manaʻo hoʻolālā, hiki iā mākou ke noʻonoʻo i nā turbines 1 a me 2 e like me ka hui pū ʻana me ka mahalo kekahi i kekahi, aʻo nā turbines 1 a me 3 (ʻelua mau mea liʻiliʻi) ua like like.

I ka hoʻomaka ʻana, he kaulike ke kahe o ke kinoea, no laila lawe i kahi turbine liʻiliʻi i ka pae mua o ka hoʻonui.

I kēia manawa ma 1500 rpm, hoʻomohala ka ʻenekini i ka ikehu o 650 Nm!

Hoʻokumu ka ʻenekini i 740 Nm (!) Mai 2000 a 3000 rpm, he mea kupaianaha ke hoʻohālikelike ʻia me ka ("wale nō") 381 hp i hana ʻia.

Eia kahi hāmeʻa BMW kūhelu e wehewehe nei pehea e holo ai:

Kūpono?

Hiki i nā loiloi o kēia ʻenekini ʻike liʻiliʻi loa ke liʻiliʻi. Hoʻokahi mea, eia naʻe, ʻo ka ʻenekini i makemake maoli ʻia e ʻoi aku ka hilinaʻi ma mua o ka ʻenekini turbocharged, keu hoʻi aia ʻekolu o lākou!
