AMG, iileta ezintathu ngonaphakade ezinxulumene V8s muscled, kwakhona ufuna ukuba "yindlovukazi" iisilinda ezine. Entsha M139 , eya kuxhobisa ikamva i-A 45, iya kuba yi-cylinder enamandla kunazo zonke emhlabeni, ifikelele kwi-421 hp emangalisayo kwi-S version.
Kuyachukumisa, ngakumbi xa sibona ukuba umthamo wale bloko intsha kuseyi-2.0 l kuphela, oko kukuthi, kuthetha (kancinci) ngaphezu kwe-210 hp / l! "Iimfazwe zamandla" zaseJamani, okanye iimfazwe zamandla, sinokuzibiza ngokuba ziyize, kodwa iziphumo azizange ziyeke ukuthakazelisa.
M 139, yintsha ngenene
I-Mercedes-AMG ithi i-M 139 ayikho into elula ye-M 133 yangaphambili exhobise uluhlu lwe-"45" ukuza kuthi ga ngoku - ngokutsho kwe-AMG, kuphela amandongomane kunye neebholithi ezimbalwa ezithwala ukusuka kwiyunithi yangaphambili.
I-injini kwafuneka ihlaziywe ngokupheleleyo, ukuphendula imingeni ebangelwa yimimiselo yokukhutshwa, iimfuno zokupakishwa kweemoto apho ziya kufakwa khona kunye nomnqweno wokunika amandla amaninzi kunye nobunzima obuncinci.
Phakathi kwezinto ezigqamayo zenjini entsha, mhlawumbi eyona igqamayo kukuba i-AMG inayo yajikelezisa i-motor 180º malunga ne-axis yayo ethe nkqo , oku kuthetha ukuba zombini i-turbocharger kunye ne-exhaust manifolds zibekwe ngasemva, ecaleni kwe-bulkhead eyahlula i-injini ye-injini kwi-cabin. Ngokucacileyo, inkqubo yokuthatha ngoku ibekwe ngaphambili.
Olu lungelelwaniso olutsha lwezisa iingenelo ezininzi, ukusuka kwindawo yembono ye-aerodynamic, evumela ukukhulisa uyilo lwecandelo elingaphambili; ukusuka kwindawo yokujonga ukuhamba komoya, ukuvumela kuphela ukubamba umoya ongaphezulu, njengoko oku ngoku kuhamba umgama omfutshane, kwaye umendo uhamba ngokuthe ngqo, kunye nokuphambuka okumbalwa, zombini kwicala lokungena kunye necala lokukhupha.
I-AMG yayingafuni ukuba i-M 139 iphinde iphendule yesiqhelo yedizili, kodwa leyo yenjini enqwenelekayo ngokwendalo.
I-turbo yanele
Kwakhona okuqaphelekayo kuphela kwe-turbocharger ekhoyo, nangona amandla athile aphezulu kakhulu. Olu luhlobo lwe-twinscroll kwaye luhamba kwi-bar ye-1.9 okanye i-2.1 bar, kuxhomekeke kwinguqulo, i-387 hp (A 45) kunye ne-421 hp (A 45 S), ngokulandelanayo.
Bhalisa kwincwadana yethu
Njengee-turbos ezisetyenziswa kwi-V8 esuka kwindlu ka-Affalterbach, i-turbo entsha isebenzisa iibheringi kwi-compressor kunye ne-turbine shafts, inciphisa ukukhuhlana koomatshini kunye nokuqinisekisa ukuba iyaphumelela. isantya esiphezulu se-169 000 rpm ngokukhawuleza.
Ukuphucula impendulo yeturbo kumazantsi, kukho iipaseji ezahlukileyo nezinxuseneyo zompompozo werhasi ephumayo ngaphakathi kwindlu ye-turbocharger, kunye ne-exhaust manifolds ibonakalisa imibhobho yokwahlula, evumela ukuhamba kwerhasi yokukhupha okwahlukileyo, kwiturbine.
I-M 139 iphinda igqame ngokubakho kwekhrankcase entsha ye-aluminium, i-crankshaft yentsimbi ekhandiweyo, iipiston ze-aluminiyam ezibunjiweyo, zonke zikwazi ukusingatha umgca obomvu omtsha kwi-7200 rpm, kunye namandla aphezulu afunyenwe kwi-6750 rpm - enye i-750 rpm kune-M. 133.
Impendulo eyahlukileyo
Ugxininiso olukhulu lwabekwa ekuphenduleni kwe-injini, ngakumbi ekuchazeni ijiko letorque. Eyona torque yenjini entsha ngoku 500 Nm (480 Nm kwinguqulo yesiseko), ekhoyo phakathi kwe-5000 rpm kunye ne-5200 rpm (4750-5000 rpm kwinguqulo yesiseko), ulawulo oluphezulu kakhulu kwizinto ezidla ngokubonwa kwiinjini ze-turbo - i-M 133 ihambisa ubuninzi be-475 Nm ngoko. kwi-2250 rpm, ukugcina eli xabiso ukuya kwi-5000 rpm.
Esi yayisisenzo sangabom. I-AMG ayizange ifune ukuba i-M 139 iphinde iphinde iphendule impendulo yedizili, kodwa leyo yenjini enqwenelekayo ngokwendalo. Ngamanye amazwi, umlingiswa we-injini, njenge-NA elungileyo, uya kukumema ukuba undwendwele ii-regimens eziphezulu rhoqo, kunye nendalo ejikelezayo ngakumbi, endaweni yokuba ubanjwe ngolawulo oluphakathi.
Kwimeko nayiphi na into, i-AMG iqinisekisa i-injini ngokusabela okuqinileyo kulo naluphi na ulawulo, nokuba luphantsi.
Amahashe ahlala ematsha
Ngamandla aphakamileyo kangaka - yeyona cylinder ine inamandla emhlabeni - inkqubo yokupholisa ibalulekile, kungekuphela nje kwinjini ngokwayo, kodwa nasekuqinisekiseni ukuba ubushushu bomoya obucinezelweyo buhlala kumanqanaba afanelekileyo.
Phakathi kwezixhobo sifumana iisekethe ezihlaziyiweyo zamanzi kunye ne-oyile, iinkqubo zokupholisa ezahlukeneyo zentloko kunye nebhlokhi ye-injini, impompo yamanzi yombane kunye neradiyetha eyongezelelweyo kwi-arch yevili, ehambelana neradiyetha ephambili ngaphambili.
Kwakhona ukugcina ukuhanjiswa kubushushu obufanelekileyo bokusebenza, i-oyile eyidingayo ipholiswa yisekethe yokupholisa ye-injini, kwaye isitshintshi sobushushu sixhonywe ngqo kuthumelo. Iyunithi yokulawula injini ayizange ilityalwe, ifakwe kwizindlu zokucoca umoya, ipholiswe ukuhamba komoya.
