AMG, zilembo zitatu zomwe zimagwirizanitsidwa kosatha ndi V8s muscled, amafunanso kukhala "mfumukazi" ya masilinda anayi. Chatsopano m139 , yomwe idzakonzekeretse tsogolo la A 45, idzakhala yamphamvu kwambiri ya 4 yamphamvu kwambiri padziko lonse lapansi, ikufika pa 421 hp yodabwitsa mu S version.
Zochititsa chidwi, makamaka tikawona kuti mphamvu ya chipika chatsopanochi ikadali 2.0 l, ndiko kuti, amatanthauza (pang'ono) kuposa 210 hp / l! "Nkhondo zamphamvu" za ku Germany, kapena nkhondo zamphamvu, titha kuzitcha zopanda pake, koma zotsatira zake sizimasiya kusangalatsa.
M 139, ndi yatsopano
Mercedes-AMG imati M 139 sikusintha kosavuta kwa M 133 yapitayo yomwe yakhala ndi "45" mpaka pano - malinga ndi AMG, mtedza ndi ma bolt ochepa okha amanyamula kuchokera kugawo lapitalo.
Injiniyo inayenera kukonzedwanso kwathunthu, kuti igwirizane ndi zovuta zomwe zimadza ndi malamulo otulutsa mpweya, zofunikira zonyamula magalimoto kumene zidzayikidwe komanso ngakhale chikhumbo chopereka mphamvu zambiri komanso kulemera kochepa.
Zina mwazinthu zazikulu za injini yatsopanoyi, mwina yomwe imadziwika kwambiri ndi yakuti AMG ili nayo inazungulira motere 180º mozungulira molunjika , kutanthauza kuti turbocharger ndi manifolds otulutsa mpweya amayikidwa kumbuyo, pafupi ndi bulkhead yomwe imalekanitsa chipinda cha injini ku kanyumba. Mwachiwonekere, dongosolo lodyera tsopano lili kutsogolo.
Kukonzekera kwatsopano kumeneku kunabweretsa ubwino wambiri, kuchokera kumalo a aerodynamic, kulola kukhathamiritsa mapangidwe a gawo lakutsogolo; kuchokera kumbali ya kayendedwe ka mpweya, kulola osati kungotenga mpweya wochuluka, monga momwe izi tsopano zikuyenda mtunda waufupi, ndipo njirayo ndi yolunjika, ndi zopotoka zochepa, zonse kumbali yolowera komanso kumbali yotulutsa mpweya.
AMG sanafune kuti M 139 ifanane ndi momwe dizilo imayankhira, koma ya injini yolakalaka mwachilengedwe.
Turbo ndi yokwanira
Chodziwikanso ndi turbocharger yokhayo yomwe ilipo, ngakhale ili ndi mphamvu zapadera kwambiri. Uwu ndi mtundu wa twinscroll ndipo umayenda pa bar 1.9 kapena 2.1 bar, kutengera mtundu, 387 hp (A 45) ndi 421 hp (A 45 S), motsatana.
Lembetsani ku kalata yathu yamakalata
Monga ma turbos omwe amagwiritsidwa ntchito mu V8 kuchokera ku nyumba ya Affalterbach, turbo yatsopano imagwiritsa ntchito ma fani mu compressor ndi turbine shafts, kuchepetsa mikangano yamakina ndikuwonetsetsa kuti ikukwaniritsidwa. liwiro lalikulu la 169 000 rpm mwachangu.
Kuti mayankhidwe a turbo amveke bwino, pali ndime zosiyana ndi zofananira za gasi wotuluka mkati mwa nyumba ya turbocharger, komanso ma manifolds otulutsa amakhala ndi ma ducts ogawanika, omwe amalola kuti pakhale mpweya wotuluka mwapadera.
M 139 imawonekeranso chifukwa cha kukhalapo kwa crankcase yatsopano ya aluminiyamu, crankshaft yachitsulo yonyezimira, ma pistoni opangidwa ndi aluminiyamu, onse kuti azitha kuwongolera mtundu watsopano wa 7200 rpm, ndipo mphamvu yayikulu ikupezeka pa 6750 rpm - ina 750 rpm kuposa mu M. 133.
Yankho losiyana
Chidwi chachikulu chinayikidwa pa kuyankha kwa injini, makamaka pofotokozera mapindikidwe a torque. The makokedwe pazipita injini latsopano tsopano 500 nm (480 Nm m'munsi Baibulo), likupezeka pakati pa 5000 rpm ndi 5200 rpm (4750-5000 rpm mu Baibulo m'munsi), ulamuliro wapamwamba kwambiri zimene nthawi zambiri kuoneka mu injini Turbo - M 133 anapereka munthu pazipita 475 Nm ndiye pa 2250 rpm, kusunga mtengo uwu mpaka 5000 rpm.
Uku kunali kuchita dala. AMG sanafune kuti M 139 ifanane ndi momwe dizilo imayankhira, koma ya injini yolakalaka mwachilengedwe. Mwa kuyankhula kwina, khalidwe la injini, monga mu NA wabwino, lidzakuitanani kuti mukachezere maulamuliro apamwamba nthawi zambiri, ndi chikhalidwe chozungulira, m'malo mogwidwa ndi maulamuliro apakati.
Mulimonsemo, AMG amatsimikizira injini ndi kulabadira amphamvu ku boma lililonse, ngakhale otsika kwambiri.
Mahatchi nthawi zonse amakhala atsopano
Ndi mphamvu zapamwamba zotere zamphamvu - ndiye silinda yamphamvu kwambiri padziko lonse lapansi - njira yozizirira ndiyofunikira, osati injini yokhayo, komanso kuwonetsetsa kuti kutentha kwa mpweya kumakhalabe koyenera.
Pakati pa arsenal timapeza mabwalo okonzedwanso amadzi ndi mafuta, makina ozizirira osiyana a mutu ndi injini ya injini, pampu yamadzi yamagetsi yamagetsi komanso ma radiator owonjezera pama wheel arch, omwe amakwaniritsa radiator yayikulu kutsogolo.
Komanso kusunga kufalikira pa kutentha kwabwino kwa ntchito, mafuta omwe amafunikira amazizidwa ndi dera lozizira la injini, ndipo chowotcha chotenthetsera chimayikidwa mwachindunji pamayendedwe. Chigawo choyang'anira injini sichinayiwalidwe, chimayikidwa mu nyumba ya fyuluta ya mpweya, itakhazikika ndi kutuluka kwa mpweya.
