Ọdịiche dị n'etiti ike dị elu EA888 Gen3 na injin dị ala EA888 Gen3B (ọgbọ atọ na ọkara) buru ibu n'ezie. N'ihi iji sistemu combustion dị iche iche na ebumnuche arụmọrụ, enwere ọtụtụ ọdịiche na ngwaike, ọkachasị ndịiche ndị a:
1. Usoro mgba ọkụ dị iche iche:
Ike dị elu EA888 Gen3 na-anabata okirikiri Otto ọdịnala, ebe obere ike EA888 Gen3B na-eji okirikiri Miller belata oriri mmanụ, yabụ pistons, ụlọ combustion isi cylinder, ọdụ ụgbọ mmiri isi cylinder, injectors, oke mkpakọ, wdg nke abụọ dị iche.
Gịnị bụ okirikiri Miller?
EA888 Gen3B dị obere na-eji mmechi mbụ nke valvụ oriri iji nweta combustion na oke mgbasawanye karịa oke mkpakọ, si otú ahụ na-emeziwanye arụmọrụ ọkụ. N'ikwu okwu n'ozuzu, okirikiri Miller ga-eweta nnukwu mfu arụmọrụ. Emebere akụkụ oriri nke injin EA888 Gen3B site na iji sistemu valvụ na-agbanwe agbanwe AVS, nke na-eji teknụzụ valvụ na-agbanwe agbanwe iji dozie akụkụ nke mfu arụmọrụ nke okirikiri Miller kpatara. Ya mere, ebumnuche Volkswagen n'ịzụlite ike dị ala EA888 Gen3B bụ iji nweta ọkwa oriri mmanụ nke 1.4T yana ọkwa arụmọrụ nke 1.8T.

Ọdịiche dị n'etiti okirikiri GEN3 Otto na okirikiri GEN3B Miller
(1) Ihe dị iche na valvụ na piston imewe: GEN3B's valve valve dayameta dị ntakịrị na piston n'elu dị elu, nke nwere ike nweta oke mkpakọ nke 11.7 (GEN).
Oke mkpakọ 3 bụ 9.8).
(2) Ọdịiche dị na ọdụ ụgbọ elu na imepụta profaịlụ cam: GEN3B na-eji ọdụ ụgbọ mmiri buru ibu na-ebuli elu na profaịlụ cam dị ala iji nweta okirikiri Miller.
2. Ọdịiche dị na mgbanwe valvụ ebuli AVS imewe
Sistemụ ebuli valvụ na-agbanwe agbanwe AVS nke ike dị elu EA888 Gen3 dị n'akụkụ ikuku. Nke a bụ okirikiri nhọrọ ukwuu AVS nke EA888, bụ nke mere kemgbe ọgbọ nke abụọ. Nzube ya bụ isi bụ imeziwanye ụda ike dị ala na nzaghachi ike dị egwu ma belata turbo lag.
Sistemụ ebuli valvụ na-agbanwe agbanwe AVS nke obere ike EA888 Gen3B nọ n'akụkụ oriri, ọkachasị iji mejupụta akụkụ nke ike mfu nke okirikiri Miller kpatara (mana ọ ka enweghị ike iru ọkwa arụmọrụ nke ike dị elu).
3. Ọdịiche dị na nhazi nke mmanụ-gas
The mmanụ-gas separator nke elu-ike version nke EA888 Gen3 na-ejikọta ya kpọmkwem site crude mmanụ separator oghere nke cylinder block na ezi mmanụ-gas separator na cylinder isi.
Iji nweta mma mmanụ-gas nkewa na n'ihu belata mmanụ oriri, ndị ala-ike version nke EA888 Gen3b na-eji oghere nke oriri-n'akụkụ itule aro na cylinder block dị ka isi mmanụ-gas separator, na enweta isi nkewa site na elu-ọsọ ntughari nke itule aro (na-agba bụ ugboro abụọ nke crankshaft isi), na mgbe ahụ - na cylinder na-aga nke ọma. Nhazi a ga-enwe obere oriri mmanụ.
4. Ọdịiche dị na crankshaft dayameta
Igwe GEN3B dị obere ike na-ahọrọ dayameta crankshaft isi ogwe aka iji belata esemokwu ma belata oriri mmanụ.
5. Ọdịiche na oriri mmanụ
Enwere ike ịhụ na ụdị ike dị ala nke GEN3B bụ nke a haziri nke ọma iji nweta obere mmanụ ọkụ na ịrụ ọrụ dị elu. Ya mere, arụmọrụ nke obere ike nke GEN3B nwere ike imeziwanye ihe dịka 8% ma e jiri ya tụnyere ụdị ike dị elu nke GEN3.
Ebelatala oriri mmanụ ụgbọala n'ụdị ọrụ niile:
