Isu tinopfuurira nhepfenyuro yeaya epamberi ehunyanzvi mhinduro mune akasiyana mayuniti

Iyo nyowani matanhatu-humburumbira peturu injini M 256

Iyo M256 inoratidza zvakare kudzoka kweMercedes-Benz kumutsara wepakutanga weiyo masirinda matanhatu. Makore akati wandei apfuura, iyo M272 KE35 mitanhatu-humburumbira yemuchadenga mayuniti ane jekiseni muzvikamu zvekudya (KE-kanaleinspritzung) yakatsiviwa panguva imwechete nekona pakati pemitsara yemasilinda yemadhigirii makumi mana neM90 DE 276 ine jekiseni rakananga (DE-direkteinspritzung neiyo kona ye35 yakweretwa kubva kuinjiniya dzeChrysler dzePentastar. Mutsivi wezvikamu zviviri zvakasarudzika zvinoshushikana ndeye M60 DELA276 ine V30 dhizaini, ine kufambiswa kwemarita matatu uye kumanikidza kuchaja nema turbocharger maviri. Kunyangwe paine hama yepamoyo yekupedzisira, Mercedes inoitsiva ne-in-mutsara matanhatu-humburumbira M 6 injini, pakutanga yakagadzirirwa 256-volt magetsi system. Basa guru rekupedzisira nderekuchainisa yemagetsi michina compressor iyo inozadza iyo turbocharger (yakafanana neiyo yeAudi's 48 TDI injini) - yekutanga mhinduro yakadaro muchikamu chepeturu. Iyo simba sosi ndiyo Yakabatanidzwa Starter jenareta (ISG), yakaiswa munzvimbo yeiyo flywheel uye lithium-ion bhatiri. Panguva imwecheteyo, iyo ISG inotamba chinzvimbo chechimwe chinhu chemasystem system, asi iine yakadzika kwazvo magetsi pane apfuura mhinduro dzakafanana.

Muchokwadi, iyo yakawanda yechinhu chakakosha cheinjini pachayo uye yakagadzirwa sechikamu chayo kubva pakutanga chaiko kwebasa rekusimudzira pabhasikoro. Iine 15kW yesimba uye 220Nm yetorque, ISG inobatsira nekumhanyisa kukurumidza uye yekutanga peak torque, pamwe neiyo yambotaurwa yemagetsi supercharger, inosvika 70rpm mu000ms. Uye zvakare, iyo sisitimu inodzoreredza simba panguva yekubhureki, inobvumira inogara ichimhanya ine simba remagetsi chete uye kushanda kweinjini munzvimbo inoshanda zvakanyanya ine mutoro wepamusoro, zvichiteerana kuvhurika kwakakura kana kushandisa bhatiri sebhafa yekuchaja. Ne 300 volt magetsi emagetsi zvakare vatengi vakakura senge pombi yemvura uye compressor yemhepo inofefetera. Kutenda kune zvese izvi, iyo M 48 haidi peripheral mechanism yekutyaira jenareta, kana yekutanga, nekudaro ichisunungura nzvimbo kunze kwayo. Iyo yekupedzisira inogarwa neyakamanikidzwa kuzadza system ine yakaoma sisitimu yemhepo ducts inotenderedza injini. Iyo M256 itsva ichaunzwa zviri pamutemo gore rinouya muS-Kirasi itsva.

Kutenda kune ISG, yekutanga yekunze uye jenareta inochengetwa, iyo inoderedza kureba kweinjini. Iyo yakanyanya kurongeka pamwe nekuparadzaniswa kwemaitiro ekutora uye ekupera simba inobvumirawo kurongeka kwepedyo kwechigadziriso uye hurongwa hutsva hwekuchenesa zvidimbu zvakasimba (zvinoshandiswa kusvika zvino chete mumajini edizeli). Mushanduro yayo yekutanga, muchina mutsva une simba uye torque inosvika padanho rezvino sere-cylinder injini ine 408 hp. uye 500 Nm, ine 15 muzana kuderedzwa kwemafuta ekushandisa uye kubuda kana ichienzaniswa neino M276 DELA 30. Nekusimuka kwayo kwe500 cc per cylinder, iyo itsva unit ine yakafanana optimal, uye maererano neBMW mainjiniya, displacement seyayo maviri-litre injini yedhiziri yakaunzwa gore rapfuura uye itsva maviri-litre four-cylinder injini yepeturu.

Nyowani, diki asi ine simba kwazvo 4.0 litita V8 injini

Pakuratidzira kusikwa kwechikwata chake muchimiro cheM 176 nyowani, mukuru wedhipatimendi remajini-masere-masere, Thomas Ramsteiner, akataura achidadisa. "Basa redu ndiro rakaomesesa. Isu tinoda kugadzira injini masere-humburumbira inogona kukwana pasi pehodhi yeC-Kirasi. Dambudziko nderekuti vatinoshanda navo vanogadzira ina- uye matanhatu-masilinda injini vane yakawanda nzvimbo yekugadzirisa zvakakwana zvinhu zvakaita sekudya uye kupedza masisitimu uye kutonhora kwemhepo. Tinofanira kurwisana neese cubic sentimita. Isu takaisa iyo turbocharger mukati memukati meesirinda uye nemhepo inotonhorera pamberi pavo. Nekuda kwekuunganidzwa kwekupisa, isu tinopfuurira kutenderera kwechitonhorera uye nekuchengetedza mafeni aripo kunyangwe injini yamiswa. Kudzivirira zvinoriinjini, mafirifuru uye maturbocharger akaputirwa nemweya. "

Iyo M 176 ine diki yekusimuka pane yakatangira iyo M 278 (4,6 malita) uye inotorwa kubva kuAMG M 177 (Mercedes C63 AMG) uye M 178 (AMG GT) zvikamu zvine zvinobuda muhuwandu hwe462 hp. kusvika ku612 hp Kusiyana neyekupedzisira, iyo yakaunganidzwa pane imwe-man-one-injini hwaro muAffalterbach, iyo M 176 ichave yakapararira, yakaunganidzwa muStuttgart-Untertürkheim uye ichatanga iine simba rekubuda kwe476 hp, yakakura torque ye700 Nm uye. ichapedza 10 muzana mafuta mashoma. Pasina chiyero chidiki, izvi zvinokonzerwa nekugona kudzima mana emasilinda masere pakuremerwa kweinjini. Iyo yekupedzisira inoitwa nerubatsiro rweCAMTRONIC variable valve timing system, umo kushanda kwemasilinda mana kunoshandura kune imwe yepamusoro yekutakura mode ine yakafara throttle kuvhura. Sere actuators axially chinja zvinhu nemacams kuitira kuti mavharuvhu mana awo amire kuvhura. Iyo mana-cylinder oparesheni modhi inoitika mune rev modes kubva pa900 kusvika 3250 rpm, asi kana rakawanda simba richidikanwa, rinodzima mukati memilliseconds.

Yakakosha centrifugal pendulum muflywheel ine basa rekudzikisa ese echina-order vibration mauto mu8-cylinder oparesheni uye yechipiri-kurongeka vibration masimba mu4-cylinder oparesheni. Kushanda kweThermodynamic kunovandudzwawo nekubatanidzwa kwebiturbo kuchaja uye jekiseni rakananga rine jekiseni riri pakati (ona bhokisi) uye NANOSLIDE coating. Iyo inobvumira majekiseni akawanda ekusanganisa zvirinani, uye iyo yakavharwa dhizaini injini yakagadzirwa nealuminium alloys uye inomira kumanikidzwa kwe140 bar.

China-humburumbira peturu M 264 neMiller kutenderera

Iyo peturu nyowani ina-humburumbira turbocharger inobva kune imwechete modular injini chizvarwa seM 256 uye ine yakafanana humbowo dhizaini. Sekureva kwaNico Ramsperger kubva kune ina-humburumbira injini dhipatimendi, yakavakirwa pane iri nyowani M 274, yatatotaura nezvayo. Muzita rekumhanyisa kuita kweinjini, iyo mbiri-jet turbocharger inoshandiswa, semu AMG's M 133, uye simba rerita rinopfuura 136 hp / l. Senge hombe M 256, inoshandisa 48-volt magetsi system, asi zvakasiyana nayo ndeyekunze, inofambiswa nebhandi uye inoita seanotangisa-jenareta, ichibatsira mota kutanga uye kumhanyisa uye ichibvumira shanduko inoshanduka poindi yekushandisa. Iyo inoshanduka gasi yekuparadzira system inopa kushanda pane yedu Miller kutenderera.
