Nā Kūlana Nui o GE 7FDL Engine
ʻO ka moʻo GE 7FDL he ʻehā-stroke medium-speed diesel engine i hana ʻia e General Electric (GE). Hoʻolālā mua ʻia ia no ka traction locomotive railway, a pili pū i nā ʻōnaehana mana moana a me nā ʻāpana hana mana. Aia ma lalo kona mau palena ʻenehana koʻikoʻi a me nā kikoʻī kikoʻī o nā hiʻohiʻona me nā helu cylinder like ʻole.
I. Nā ʻāpana ʻenehana kumu
Nā mea kiko'ī kiko'ī
Mea Hana GE Transportation Systems
ʻO ka manawa hana 1956 a hiki i kēia manawa (hoʻohana nui ʻia i nā kumu hoʻohālikelike ma hope o 2004)
ʻAno Paʻi ʻEhā
Cylinder Arrangement V-type hoʻonohonoho me ka 45° i hoʻokomo ʻia
Puka Poʻo 9 ʻīniha (228.6 mm)
Piston Stroke 10.5 iniha (266.7 mm)
ʻO ke ʻano o ka hoʻouka ʻana
Pūnaehana wahie Direct injection
ʻAno Diesel
Pūnaehana hoʻoluʻu wai
ʻO ka māmā holo helu 450~1,050 rpm (ka māmā hana maʻamau: 600~900 rpm)
Pākuʻi Pākī Ma kahi o 16.5:1 (ʻokoʻa liʻiliʻi ma waena o nā kumu hoʻohālike like ʻole)
Ka hoʻoneʻe ʻana i kēlā me kēia Cylinder Ma kahi o 18.68 L (waiwai helu: π×(228.6/2)²×266.7×10⁻⁹)
II. Nā ʻāpana kikoʻī o nā kumu hoʻohālike me nā helu cylinder ʻokoʻa
Ka helu kumu hoʻohālikelike o ka hoʻoneʻe ʻana o nā pahu pahu (L) ka mana mana (hp) nā noi maʻamau
7FDL-8 8 Ma kahi o 149.4 1,400～1,800 Locomotives liʻiliʻi (e laʻa, GE CM20EMP), nā locomotives hoʻololi
7FDL-12 12 Ma kahi o 224.2 2,000～3,300 mau locomotive liʻiliʻi liʻiliʻi (e laʻa, GE P32AC-DM lua-mode locomotive)
7FDL-16 16 Ma kahi o 298.9 2,400～4,400 Locomotives nui (e laʻa, AC4400CW, Dash 9-44CW)
