Izinjini zokuhlola ezintsha zeMercedes: Ingxenye III - Uphethiloli

Siyaqhubeka nochungechunge lwezixazululo ezithuthukile zobuchwepheshe ebangeni lamayunithi

Injini entsha kaphethiloli eyisithupha eyisilinda engu-M 256

IM256 ibuye ibonise ukubuyela kweMercedes-Benz olayini boqobo bama-cylinders ayisithupha. Eminyakeni embalwa eyedlule, amayunithi asemkhathini we-M272 KE35 ayisithupha-cylinder anomjovo kumanifolds wokudla (KE-kanaleinspritzung) athathelwe indawo ngasikhathi sinye nge-angle phakathi kwemigqa yesilinda yama-90 degrees no-M276 DE 35 ngomjovo oqondile (i-DE-direkteinspritzung I-engeli engu-60 yabolekwa ezinjinini zikaChrysler zikaPentastar. Olandele lezi zingxenye ezimbili ezihlosiwe ngokwemvelo kwaba yi-M276 DELA30 enezakhiwo ze-V6, ezinokufuduswa kwamalitha amathathu nokushaja ngenkani ngama-turbocharger amabili. Ngaphandle kwentsha eyisihlobo yokugcina, abakwaMercedes bazoyifaka esikhundleni senjini elayinini eyisilinda eyisithupha M 256, eyayifakwe uhlelo lukagesi lwama-volt angama-48. Umsebenzi omkhulu wokugcina wukushayela umshini wokucindezela kagesi ogcwalisa i-turbocharger (efana nenjini ye-Audi's 4.0 TDI) - okuyisisombululo sokuqala esinjalo engxenyeni kaphethiloli. Umthombo wamandla yi-Integrated Starter Generator (ISG), ebekwe endaweni yebhethri kanye nebhethri le-lithium-ion. Ngasikhathi sinye, i-ISG idlala indima yesici sohlelo lwe-hybrid, kepha ngevolthi ephansi kakhulu kunezixazululo ezifanayo zangaphambilini.

Eqinisweni, iyingxenye ebalulekile yenjini ngokwayo futhi yaklanywa njengengxenye yayo kusukela ekuqaleni komsebenzi wokuthuthukiswa kwebhayisikili. Ngamandla ayo angu-15kW kanye ne-torque engu-220Nm, i-ISG isiza ukuletha i-acceleration ne-torque yangaphambi kwesikhathi, kanye ne-supercharger kagesi eshiwo ngenhla, efinyelela ku-70 000rpm ku-300ms. Ngaphezu kwalokho, isistimu ithola amandla ngesikhathi sokubhuleka, ivumela ukunyakaza kwesivinini esingaguquki ngamandla kagesi kuphela kanye nokusebenza kwenjini endaweni esebenza kahle kakhulu enomthwalo ophakeme, ngokulandelanayo ukuvulwa okubanzi kwe-throttle noma ukusebenzisa ibhethri njengesilondolozi sokushaja. Ngamandla kagesi angu-48 volt kukhona nabathengi abakhulu njengepompo yamanzi kanye ne-compressor ye-air conditioner. Ngenxa yakho konke lokhu, i-M 256 ayidingi umshini we-peripheral ukushayela i-generator, noma i-starter, ngaleyo ndlela ikhulule isikhala ngaphandle kwayo. Lesi sakamuva sithathwe uhlelo lokugcwalisa oluphoqelelwe ngohlelo oluyinkimbinkimbi lwemigudu yomoya ezungeza injini. I-M256 entsha izokwethulwa ngokusemthethweni ngonyaka ozayo e-S-Class entsha.

Ngenxa ye-ISG, isiqalisi sangaphandle kanye nejeneretha zigcinwa, okunciphisa ubude benjini. Isakhiwo esifanele ngokuhlukaniswa kwezinhlelo zokuthatha kanye ne-exhaust nakho kuvumela ukuhlelwa okuseduze kwe-catalyst kanye nesistimu entsha yokuhlanza izinhlayiya eziqinile (ezisetshenziswa kuze kube manje kuphela ezinjini zedizili). Enguqulweni yawo yokuqala, umshini omusha unamandla kanye ne-torque efinyelela ezingeni lezinjini zamanje ezinamasilinda ayisishiyagalombili ne-408 hp yayo. kanye ne-500 Nm, okunciphise ukusetshenziswa kukaphethiloli kanye nentuthu ephuma ngamaphesenti angu-15 uma kuqhathaniswa ne-M276 DELA 30 yamanje. Ngokususwa kwayo okungu-500 cc isilinda ngasinye, uphiko olusha lunomthamo ofanayo, futhi ngokusho konjiniyela bakwa-BMW, ​​ukugudluzwa njengalokho kwe ezimbili litre injini kadizili eyethulwe nyakenye kanye nentsha enamalitha amabili four-cylinder kaphethroli.

Injini entsha, encane kodwa enamandla kakhulu engu-4.0 litre V8

Ngesikhathi ethula ukwakhiwa kweqembu lakhe ngesimo se-M 176 entsha, inhloko yomnyango wezokuthuthukiswa kwezinjini eziyizigaxa eziyisishiyagalombili, uThomas Ramsteiner, ukhulume ngokukhulu ukuziqhenya. "Umsebenzi wethu unzima kakhulu. Sidinga ukudala ukwakheka kwenjini eyisilinda eyisishiyagalombili engangena ngaphansi kwe-C-Class. Inkinga ukuthi osebenza nabo abakha izinjini zamasilinda amane kanye nesithupha banesikhala esiningi sokuklama kahle izinto ezinjengezinhlelo zokudla nezokukhipha kanye nokupholisa umoya. Kufanele silwe nawo wonke amasentimitha angama-cubic. Sibeke ama-turbocharger ngaphakathi kwamasilinda nangama-cooler air phambi kwawo. Ngenxa yokuqoqana kokushisa, siyaqhubeka nokusakazwa kwesipholisi futhi sigcina abalandeli beqhubeka ngisho nangemuva kokumiswa kwenjini. Ukuvikela izingxenye zenjini, ama-exhaust manifolds amaningi kanye nama-turbocharger afakwa ngumoya oshubile. "

I-M 176 inokususwa okuncanyana kunokwandulele i-M 278 (4,6 litres) futhi iphuma kumayunithi e-AMG M 177 (Mercedes C63 AMG) kanye ne-M 178 (AMG GT) anemiphumela ebangeni elingu-462 hp. kuze kufike ku-612 hp Ngokungafani nalezi zakamuva, ezihlanganiswe ngesisekelo senjini yomuntu oyedwa e-Affalterbach, i-M 176 izosakazeka kakhulu, ihlanganiswe e-Stuttgart-Untertürkheim futhi izoqale ibe namandla okukhipha angu-476 hp, i-torque ephezulu engu-700 Nm kanye izosebenzisa uphethiloli ongaphansi ngamaphesenti ayishumi. Ngesilinganiso esincane, lokhu kungenxa yekhono lokucisha amasilinda amane kwayisishiyagalombili ekulayisheni kwenjini ngokwengxenye. Lokhu kokugcina kwenziwa ngosizo lwesistimu yesikhathi se-valve eguquguqukayo ye-CAMTRONIC, lapho ukusebenza kwamasilinda amane kushintshela kumodi yokulayisha ephakeme ngokuvula okubanzi kwe-throttle. Ama-actuator ayisishiyagalombili asusa izakhi ngamakhamera ukuze ama-valve amane awo ayeke ukuvuleka. Imodi yokusebenza yamasilinda amane yenzeka kumamodi okuvuselela ukusuka ku-10 kuye ku-900 rpm, kodwa uma kudingeka amandla engeziwe, iyacisha phakathi kwama-millisecond.

I-pendulum ekhethekile eyi-centrifugal ku-flywheel inomsebenzi wokunciphisa kokubili amandla okudlidliza ohlelo lwesine ekusebenzeni kwamasilinda angu-8 kanye namandla okudlidliza okuhlelwa kwesibili ekusebenzeni kwamasilinda angu-4. Ukusebenza kahle kwe-Thermodynamic nakho kuthuthukiswa ngokuhlanganiswa kokushaja kwe-biturbo nomjovo oqondile ngomjovo osendaweni emaphakathi (bheka ibhokisi) kanye ne-NANOSLIDE coating. Ivumela ukujova okuningi ukuze kuxutshwe kangcono, futhi injini yedekhi evaliwe yenziwe ngama-alloys e-aluminium futhi imelana nokucindezela kwe-140 bar.

Uphethiloli oyisilinda ezine u-M 264 nomjikelezo weMiller

I-turbocharger entsha kaphethiloli ophethiloli abane isuka enjini efanayo yemoduli njenge-M 256 futhi inokwakhiwa kwamasilinda okufanayo. Ngokusho kukaNico Ramsperger ovela emnyangweni wezinjini ezine-cylinder, kusekelwe ku-M 274 esesikhulume ngayo. Egameni lokusabela ngokushesha kwenjini, kusetshenziswa i-double-jet turbocharger, njengaku-M 133 we-AMG, kanti amandla elitha angaphezu kuka-136 hp / l. Njenge-M 256 enkudlwana, isebenzisa uhlelo lokuphakela ugesi lwama-volt angama-48, kodwa ngokungafani nayo ingeyangaphandle, iqhutshwa ngamabhande futhi isebenza njenge-starter-generator, isiza imoto ekuqaliseni nasekusheshiseni nasekuvumeleni ushintsho lwendawo yokusebenza. Uhlelo lokusabalalisa igesi oluguquguqukayo luhlinzeka ngokusebenza kumjikelezo wethu weMiller.
