I-AMG, izinhlamvu ezintathu ezihlotshaniswa ingunaphakade nama-V8 anemisipha, ifuna nokuba “indlovukazi” yamasilinda amane. Okusha M139 , ezohlomisa ikusasa i-A 45, izoba yi-four-cylinder enamandla kakhulu emhlabeni, ifinyelele ku-421 hp emangalisayo enguqulweni ye-S.
Okuhlaba umxhwele, ikakhulukazi uma sibona ukuthi amandla ale block entsha kuseyi-2.0 l kuphela, okungukuthi, kusho (kancane) ngaphezu kuka-210 hp/l! "Izimpi zamandla" zaseJalimane, noma izimpi zamandla, singazibiza ngokuthi ziyize, kodwa imiphumela ayiyeki ukuthakazelisa.
M 139, yintsha ngempela
I-Mercedes-AMG ithi i-M 139 akuyona into elula ye-M 133 edlule futhi isihlomise uhla lwe-"45" kuze kube manje - ngokusho kwe-AMG, amantongomane ambalwa kuphela namabhawodi aphuma eyunithi yangaphambilini.
Injini bekumele iklanywe kabusha ngokuphelele, ukuze ibhekane nezinselelo ezilethwa yimithetho ye-emission, izidingo zokupakishwa kwezimoto lapho izofakwa khona kanye nesifiso sokunikeza amandla engeziwe nesisindo esincane.
Phakathi kwezinto ezigqamile ngenjini entsha, mhlawumbe okugqame kakhulu ukuthi i-AMG inakho ijikise injini ngo-180º mayelana ne-eksisi yayo eqondile , okusho ukuthi kokubili i-turbocharger kanye ne-exhaust manifolds kumiswe ngemuva, eduze kwe-bulkhead ehlukanisa ingxenye yenjini nekhabini. Ngokusobala, uhlelo lokuthatha manje selumi phambili.
Lokhu kumiswa okusha kulethe izinzuzo ezimbalwa, ngokubuka kwe-aerodynamic, okuvumela ukukhulisa ukwakheka kwesigaba sangaphambili; kusukela ekubukeni kokugeleza komoya, okungavumeli kuphela ukubamba umoya owengeziwe, njengoba lokhu manje kuhamba ibanga elifushane, futhi indlela iqonde kakhulu, ngokuphambuka okumbalwa, kokubili ohlangothini lokuthatha kanye nasohlangothini lwe-exhaust.
I-AMG ibingafuni ukuthi i-M 139 iphindaphinde impendulo ejwayelekile kadizili, kodwa kunalokho okwenjini efisa ngokwemvelo.
I-turbo yanele
Okunye okuphawulekayo wukuphela kwe-turbocharger ekhona, naphezu kwamandla athile aphezulu kakhulu. Lolu wuhlobo lwe-twinscroll futhi lusebenza kubha engu-1.9 noma ibha engu-2.1, kuye ngenguqulo, 387 hp (A 45) no-421 hp (A 45 S), ngokulandelanayo.
Bhalisela iphephandaba lethu
Njenge-turbos esetshenziswe ku-V8 esuka endlini ka-Affalterbach, i-turbo entsha isebenzisa ama-bearings ku-compressor nama-turbine shafts, yehlisa ukungqubuzana kwemishini nokuqinisekisa ukuthi iyaphumelela. isivinini esiphezulu se-169 000 rpm ngokushesha.
Ukuze kuthuthukiswe ukusabela kwe-turbo ezindaweni eziphansi, kunezikhala ezihlukene nezihambisanayo zokugeleza kwegesi ephumayo ngaphakathi kwendlu ye-turbocharger, kanye nama-multifolds e-exhaust afaka amapayipi ahlukanisiwe, okuvumela ukugeleza okuhlukile, okukhethekile kwegesi yokukhipha umoya ku-turbine.
I-M 139 iphinde igqame ngokuba khona kwekhrankcase entsha ye-aluminium, i-crankshaft yensimbi eyenziwe ngomgunyathi, amapiston e-aluminium akhiwe, konke ukuphatha umugqa omusha obomvu ngo-7200 rpm, namandla amakhulu atholakala ku-6750 rpm - omunye u-750 rpm kunase-M. 133.
Impendulo ehlukile
Kugxilwe kakhulu ekuphenduleni kwenjini, ikakhulukazi ekuchazeni ijika letorque. I-torque enkulu yenjini entsha manje 500 Nm (480 Nm kunguqulo yesisekelo), etholakala phakathi kuka-5000 rpm no-5200 rpm (4750-5000 rpm enguqulweni yesisekelo), umbuso ophakeme kakhulu kulokho okuvame ukubonakala ezinjinini ze-turbo - i-M 133 ilethe umkhawulo we-475 Nm ngaleso sikhathi. ku-2250 rpm, igcina leli nani lifika ku-5000 rpm.
Lesi kwakuyisenzo samabomu. I-AMG ibingafuni ukuthi i-M 139 iphinde iphinde iphinde iphinde iphinde iphendule ngodizili, kodwa kunalokho kube ngeyenjini efisa ngokwemvelo. Ngamanye amazwi, uhlamvu lwenjini, njengakwi-NA enhle, luzokumema ukuthi uvakashele imibuso ephakeme kaningi, enemvelo ejikelezayo, esikhundleni sokuba ubanjwe yimibuso ephakathi.
Kunoma yikuphi, i-AMG iqinisekisa injini ngokusabela okuqinile kunoma yimuphi umbuso, ngisho nangaphansi kakhulu.
Amahhashi ahlala ehlanzekile
Ngamanani aphezulu kangaka amandla - iyisilinda esine enamandla kakhulu emhlabeni - uhlelo lokupholisa lubalulekile, hhayi enjinini ngokwayo kuphela, kodwa futhi nokuqinisekisa ukuthi izinga lokushisa lomoya elicindezelwe lihlala lisezingeni eliphezulu.
Phakathi kwe-arsenal sithola amasekhethi aklanywe kabusha amanzi nawowoyela, amasistimu okupholisa ahlukene ekhanda nelenjini, iphampu yamanzi kagesi kanye ne-radiator eyengeziwe ku-arch yamasondo, ehambisana ne-radiator enkulu ngaphambili.
Futhi ukuze kugcinwe ukudluliswa kwezinga lokushisa elifanelekile lokusebenza, uwoyela eliwadingayo apholiswa yisekethe yokupholisa yenjini, futhi isishintshi sokushisa sigxunyekwa ngqo ku-transmission. Iyunithi yokulawula injini ayikhohlwanga, ifakwe endaweni yokuhlunga umoya, ipholiswa ukugeleza komoya.

Sizobona i-M 139, injini enamandla kunazo zonke emhlabeni enamasilinda amane (ukukhiqiza), ifika kuqala kwiMercedes-AMG A 45 kanye ne-A 45 S - konke kukhomba kuyo ekuqaleni kwenyanga ezayo - bese ivela e-CLA futhi kamuva e-GLA
Njengezinye izinjini ezine-AMG seal, iyunithi ngayinye izohlanganiswa ngumuntu oyedwa kuphela. AbakwaMercedes-AMG baphinde bamemezela ukuthi ulayini wokuhlanganisa walezi zinjini usulungiselelwe ngezindlela ezintsha namathuluzi, okuvumela ukuncipha kwesikhathi sokukhiqiza ngeyunithi ngayinye cishe ngo-20 kuya ku-25%, okuvumela ukukhiqizwa kwezinjini eziyi-140 M 139 ngosuku, ukusabalala. amajika amabili.
