Emva kweminyaka eyi-18 yemveliso, iMercedes-Benz iya kuzishiya iinjini zeV6. Ikamva lophawu lenziwe ngeenjini zeemodyuli.
Kangangeminyaka kunye neminyaka sivile ii-brand ezininzi zisithi ii-injini ze-V6, xa kuthelekiswa ne-in-line six-cylinder engines, zazingabizi ukuvelisa kwaye kulula ukuzilungisa, ngoko ke ukhetho olungcono. Kwimeko kaMercedes-Benz, le nkcazo yenza ingqiqo ngakumbi kuba iinjini zayo ezininzi ze-V6 zithathwe ngokuthe ngqo kwiibhloko ze-V8. Uphawu lweStuttgart lunqumle iisilinda ezimbini kwiibhloko zabo ze-V8 kwaye bye, babenenjini ye-V6.AKUMELE UPHOSE: IVolkswagen Passat GTE: ihybrid ene-1114 km yokuzimela
Ingxaki ngesi sisombululo? Kwi-injini ye-90º V8 ugqabhuko-dubulo olukwisilinda enye luthelekiswa nolandelelwano logqabhuko-dubulo kumbhobho ochaseneyo, okukhokelela kubuchwephesha obulungeleleneyo nobugudileyo. Ingxaki kukuba ngeesilinda ezimbini ngaphantsi (kunye nomyalelo wokudubula okwahlukileyo) ezi njini ze-V6 bezingekho mpuluswa kwaye zingalungelelananga. Ukujongana nale ngxaki, uphawu lwanyanzelwa ukuba lubhenele kumaqhinga kwi-elektroniki ukuchasana kunye nokusebenza kakuhle kobu matshini. Kumgca we-injini ezintandathu-cylinder le ngxaki ayikho ngenxa yokuba akukho intshukumo emacaleni ukuba ubhala ngaphezulu.
Kutheni ke ngoku ubuyela kwiinjini ezinesilinda ezithandathu?
Injini ekulo mfanekiso ukhankanyiweyo yeyosapho lwenjini entsha yakwaMercedes-Benz. Kwixesha elizayo siya kufumana le injini kwiimodeli ze-S-Class, i-E-Class kunye ne-C-Class. Ngokutsho kweMercedes-Benz, le njini entsha iya kuthatha indawo yeenjini ze-V8 - ikwazi ukuvelisa ngaphezu kwe-400hp kumandla angaphezulu. iinguqulelo.
Ukuphendula umbuzo othi "kutheni ubuyela kwisithandathu ngoku ngoku", kukho izizathu ezibini ezinkulu zokuba uMercedes enze njalo. Isizathu sokuqala kukutshaja kwe-injini - i-in-line ye-injini ye-in-line ezintandathu iququzelela ukwamkelwa kwee-turbos ezilandelelanayo. Isisombululo esele sixhaphakile ngoku kunanini na ngaphambili kwaye kwiminyaka embalwa edlulileyo asizange siphindaphindeke kakhulu.
Isizathu sesibini sinento yokwenza nokuncitshiswa kweendleko. Usapho apho le njini intsha ikwimodyuli. Ngamanye amazwi, ukusuka kwibhloko efanayo kunye nokusebenzisa izinto ezifanayo, uphawu luya kukwazi ukwenza iinjini ezineesilinda ezine ukuya kwezintandathu, zisebenzisa idizili okanye ipetroli. Iskimu semveliso esele sibekwe nguBMW kunye nePorsche.
Enye into entsha yolu sapho lutsha lwee-injini kukusetyenziswa kwe-48V sub-system yombane eya kuba noxanduva lokondla icompressor yombane (efana naleyo yaziswa yi-Audi SQ7). Ngokwe-brand, le compressor iya kukwazi ukufikelela kwi-70,000 RPM kwi-300 milliseconds nje, ngaloo ndlela irhoxisa i-turbo-lag, de i-turbo engundoqo inoxinzelelo olwaneleyo lokusebenza ngokupheleleyo.
Ukongeza kokunika amandla i-compressor yombane, le sub-system ye-48V iya kuphinda inike amandla inkqubo yokupholisa umoya kwaye isebenze njenge-regenerator yamandla - ithatha ithuba lokunyathela ukuhlawula iibhetri.
Usale kakuhle kwiinjini zeRenault?
Ngaphambili, abakwaBMW babenengxaki yezitimela ezincinci zombane. Xa kujongwe umthamo wentengiso ye-MINI, bekungenakwenzeka ngokwezimali ukuba iBMW ivelise kwaye iphuhlise iinjini ukusuka ekuqaleni kwiimodeli zohlobo lwaseBritane. Ngelo xesha, isisombululo yayikukwabelana ngeenjini kunye neqela le-PSA. I-BMW iye yayeka kuphela "ukuboleka" iinjini kwiqela lamaFrentshi yakube iqalile ukuvelisa usapho lwayo lweenjini zeemodyuli.AKUMELE UPHOSEWE: Kutheni iimoto zaseJamani zilinganiselwe kwi-250 km/h?
Ngendlela elula (eyenziwe lula kakhulu…) into eyenziwa yiBMW ngoku kukuvelisa iimodyuli ukusuka kwiimodyuli ze500 cc nganye – iMercedes-Benz iye yamkela ukufuduswa okufanayo kwiimodyuli zayo. Ngaba ndifuna injini ye-1.5 litre 3-cylinder ye-MINI One? Iimodyuli ezintathu ziyadityaniswa. Ngaba ndifuna injini ye-320d? Iimodyuli ezine ziyadibana. Ngaba ndifuna injini ye-BMW 535d? Ewe uqikelele. Iimodyuli ezintandathu ziyadibana. Ngenzuzo yokuba ezi modyuli zabelana uninzi lwamacandelo, nokuba yi-MINI okanye iSeries 5.
I-Mercedes-Benz inokwenza okufanayo kwixesha elizayo, ngokukhupha iinjini ze-Renault-Nissan Alliance ezixhobisa ngoku iimodeli ezinamandla ezincinci zodidi lweKlasi A kunye noHlelo C. olu sapho lutsha lweenjini lunokubakho kulo lonke uluhlu lweMercedes-Benz - ukusuka kweyona A-Class ifikelelekayo ukuya kweyona S-Class ikhethekileyo.
