AMG, saddex xaraf oo weligood la xidhiidha V8s muruqa ah, sidoo kale waxay rabtaa inay noqoto "boqoradda" afarta dhululubo. Kan cusub M 139 , kaas oo qalabayn doona mustaqbalka A 45, wuxuu noqon doonaa afarta-dhululubo ee ugu awoodda badan adduunka, isagoo gaaraya 421 hp oo la yaab leh nooca S.
Soo jiidasho leh, gaar ahaan markaan aragno in awoodda xannibaadda cusub ay weli tahay 2.0 l oo keliya, taas oo ah, macnaheedu waa (wax yar) in ka badan 210 hp/l! Jarmalkii "dagaalladii xoogga", ama dagaalladii xoogga, waxaan ugu yeeri karnaa kuwo aan waxtar lahayn, laakiin natiijadu weligeed ma joojin inay soo jiidato.
M 139, runtii waa cusub
Mercedes-AMG ayaa sheegaysa in M 139 aanu ahayn horumar fudud ee M 133 hore oo qalabeeyay tirada "45" ilaa hadda - sida laga soo xigtay AMG, kaliya dhowr nuts iyo boolal ayaa ka qaadaya cutubkii hore.
Matoorka ayaa ahaa in si buuxda loo naqshadeeyo, si uu uga jawaabo caqabadaha ka imanaya xeerarka qiiqa, shuruudaha baakadaha ee baabuurta halkaas oo lagu rakibi doono iyo xitaa rabitaanka bixinta awood badan iyo miisaan yar.
Waxaa ka mid ah waxyaabaha ugu muhiimsan ee mishiinka cusub, laga yaabee in midka ugu muuqda uu yahay xaqiiqda ah in AMG leeyahay wuxuu matoorka u rogay 180º ku saabsan dhidigiisa toosan , taas oo macnaheedu yahay in turbocharger iyo manifoldsyada qiiqa labadaba ay ku yaalliin xagga dambe, oo ay ku xigto madaxa weyn ee ka sooca qaybta mishiinka iyo qolka. Sida cad, nidaamka qaadashada ayaa hadda la dhigay dhanka hore.
Qaabayntan cusubi waxay keentay dhowr faa'iidooyin, laga soo bilaabo aragtida aerodynamic, taas oo u oggolaanaysa in la hagaajiyo naqshadda qaybta hore; Marka laga eego dhinaca hawada, taas oo u oggolaanaysa in aan kaliya la qaadin hawo badan, maadaama tani ay hadda socoto masaafo gaaban, dariiquna waa mid toos ah, oo yar oo leexasho ah, labadaba dhinaca qaadashada iyo dhinaca qiiqa.
AMG ma aysan dooneynin M 139 inuu ku celceliyo jawaabta naaftada caadiga ah, laakiin halkii matoorka si dabiici ah loo hamiyo.
Turbo ayaa ku filan
Waxa kale oo xusid mudan turbocharger-ka kaliya ee jooga, inkasta oo ay jirto awood gaar ah oo aad u sareysa. Kani waa nooc mataano ah oo ku socda 1.9 bar ama 2.1 bar, iyadoo ku xidhan nooca, 387 hp (A 45) iyo 421 hp (A 45 S), siday u kala horreeyaan.
Isdiiwaangeli warsidahayaga
Sida turbo-yada loo isticmaalo V8 ee guriga Affalterbach, turbo cusub waxay isticmaashaa kombaresarada iyo shafka marawaxadaha, yaraynta khilaafka farsamada iyo hubinta inay ku guulaysato xawaaraha ugu badan ee 169 000 rpm si dhakhso ah.
Si loo hagaajiyo jawaabta turbo ee hoose, waxaa jira marino gaar ah oo isbarbar socda socodka gaaska qiiqa gudaha guriga turbocharger, iyo sidoo kale mawjadaha qiiqa waxay ka muuqdaan tuubooyin kala qaybsan, taas oo u oggolaanaysa gaas gaar ah oo gaar ah.
M 139 waxay sidoo kale u taagan tahay joogitaanka aluminium cusub oo aluminium ah, bir been abuur ah, bistoonnada aluminium been abuur ah, dhammaan si ay u qabtaan khad cusub oo 7200 rpm ah, oo leh awoodda ugu badan ee laga helayo 6750 rpm - 750 rpm oo kale marka loo eego M. 133.
Jawaab gaar ah
Diirad aad u weyn ayaa la saaray ka jawaab celinta matoorka, gaar ahaan qeexida qalooca torque-ga. Hirarka ugu badan ee mishiinka cusub hadda waa 500 Nm (480 Nm ee nooca saldhigga ah), oo la heli karo inta u dhaxaysa 5000 rpm iyo 5200 rpm (4750-5000 rpm ee nooca saldhigga ah), nidaam aad u sarreeya oo loogu talagalay waxa inta badan lagu arko matoorada turbo - M 133 wuxuu keenay ugu badnaan 475 Nm ka dib. 2250 rpm, iyadoo la ilaalinayo qiimahan ilaa 5000 rpm.
Tani waxay ahayd fal ula kac ah. AMG ma aysan dooneynin M 139 inuu ku celceliyo jawaabta naaftada caadiga ah, laakiin halkii matoorka si dabiici ah loo hamiyo. Si kale haddii loo dhigo, dabeecadda mishiinka, sida NA wanaagsan, waxay kugu martiqaadi doontaa inaad booqato maamullada sare marar badan, oo leh dabeecad badan oo wareeg ah, halkii aad ku qabsan lahayd maamullada dhexdhexaadka ah.
Si kastaba ha ahaatee, AMG waxay dammaanad qaadaysaa matoorka leh ka jawaab celin xooggan nidaam kasta, xitaa kuwa ugu hooseeya.
Fardo had iyo jeer cusub
Iyada oo qiimaha sare ee awoodda - waa afarta dhululubo ee ugu awoodda badan adduunka - nidaamka qaboojinta waa lagama maarmaan, ma aha oo kaliya mishiinka laftiisa, laakiin sidoo kale si loo hubiyo in heerkulka hawada cadaadisku uu ku sii jiro heerarka ugu wanaagsan.
Arsenal-ka waxaan ka heleynaa wareegyada biyaha iyo saliidda oo dib loo habeeyay, habab qaboojin oo kala duwan oo loogu talagalay madaxa iyo block engine, bamka biyaha korontada iyo sidoo kale hiitarka dheeriga ah ee qaansada giraangiraha, oo buuxinaya hiitarka weyn ee hore.
Sido kale si gudbintu ugu ilaaliso heerkulka ku haboon ee shaqada, saliidda ay u baahan tahay waxa lagu qaboojiyaa wareegga qaboojinta mishiinka, kulaylka ayaa si toos ah loogu dhejiyaa gudbinta. Qeybta kontoroolka matoorka lama iloobin, waxaa lagu dhejiyaa guryaha shaandhada hawada, iyadoo lagu qaboojinayo socodka hawada.
