UMercedes-Benz akakholelwa kumafutha enziweyo, kodwa usaqhubeka ekholelwa kwiinjini zedizili. Ukongeza kumbane, i-brand yaseJamani iyaqhubeka nokutyala imali kulo mjikelo wokutsha ukuze iphile imodeli yayo.
Ngoko ke, ngokufika kwe-Mercedes-Benz E-Class ehlaziyiweyo (isizukulwana seW213) kwimarike - eye yahlaziywa kancinane kulo nyaka - "i-vitaminized" ye-injini yedizili eyaziwayo ye-OM 654 (220 d) nazo zifike.
Yasungulwa ngo-2016, le 2.0-litre, four-cylinder, i-aluminiyam-block injini ngoku iqhuba i-evolution: the OM 654 M.
Yintoni entsha kwi-OM 654 M
Ibhloko iyafana ne-OM 654, kodwa i-peripherals iyahluka. I-OM 654 M ngoku ihambisa i-265 hp yamandla ngokuchasene ne-194 hp yesizukulwana sokuqala (esiya kuqhubeka sikhona kuluhlu lwe-E-Class) olubeka njengelona linamandla idizili ezine-cylinder emhlabeni.Iinguqulelo ezinopopayi ezinenjini ye-OM 654 M ziya kuthengiswa nge-300 d acronym.
Ukwandisa amandla ngaphezu kwe-70 hp, ukusuka kwibhloko ene-2.0 ilitha yomthamo kunye neesilinda ezine, utshintsho oluqhutywe kwi-OM 654 lwalunzulu:
- I-crankshaft entsha ene-stroke ephezulu (94 mm) ekhokelela ekunyuseni kokufuduka ukuya kwi-1993 cm3 - ngaphambi kwe-92.3 mm kunye ne-1950 cm3;
- Uxinzelelo lwe-injection lwenyuka ukusuka kwi-2500 ukuya kwi-2700 bar (+200);
- Iiturbos ezimbini zejiyometri eziguquguqukayo ezipholileyo ngamanzi;
- I-Plunger kunye ne-Nanoslide yonyango yokuchasana kunye nemigudu yangaphakathi egcwele i-sodium alloy (Na).
Njengoko abaninzi baya kwazi, i-sodium (Na) yenye yezona zimbiwa ezisetyenziswa kakhulu kwiinkqubo zefriji zezityalo zamandla enyukliya ngenxa yeempawu zayo: ukuzinza kunye nomthamo wokushisa ubushushu. Ngaphakathi kwe-OM 654 M le ntsimbi yolwelo iya kuba nomsebenzi ofanayo: ukukhusela i-motor ekugqithiseni, ukunciphisa ukungqubuzana kunye nokugqoka oomatshini.
Ukongeza kwi-turbos epholileyo yamanzi, iipistoni ezinemibhobho yangaphakathi ene-sodium alloy (Na) yenye yezona zisombululo ezinobuqili ezikhoyo kwi-OM 654 M. Kodwa ayingabo bodwa...
Phantse umbane onyanzelekileyo
Ukongeza kwezi zinto zintsha, i-OM 654 M nayo inoncedo oluxabisekileyo: i-mild-hybrid system ye-48 V. I-teknoloji kwixesha elizayo elingekude kakhulu kufuneka libe khona kuzo zonke iinjini.
Yinkqubo yombane ehambelanayo equka ijenereyitha/umqalisi kunye nebhetri, enemisebenzi emibini ebalulekileyo:
- Ukuvelisa amandla ombane kwiinkqubo zombane zemoto (i-air conditioning, i-steering, inkqubo yenkxaso yokuqhuba) ukukhulula i-injini yokutsha kulo msebenzi, ngoko ukwandisa amandla ayo;
- Ukuncedisa i-injini yokutshisa isantya, inika ukunyuka okwexeshana kumandla ukuya kwi-15 kW kunye ne-180 Nm ye-torque ephezulu. Mercedes-Benz ubiza lo msebenzi EQ Boost.
Kwakhona kwintsimi yokulwa nokukhutshwa, umsebenzi onzima wenziwa ukunyanga iigesi zokukhupha kwi-OM 654 M.
Le injini ngoku isebenzisa i-state-of-the-art i-particle filter (kunye nonyango oluphezulu lokunciphisa i-NOx deposits) kunye ne-multi-stage SCR (i-Selective Catalytic Reduction) inkqubo ehlohla i-Adblue (32.5% urea ecocekileyo, i-67.5% yamanzi e-demineralised) inkqubo yokukhupha ukuguqula i-NOx (i-nitrogen oxides) ibe yi-nitrogen kunye namanzi (umphunga).
Yintoni esinokuyilindela kwi-300d?
Xa ifika emarikeni, i-OM 654 M izakwaziwa nge-300 d — yiloo nto esiza kuyifumana ngasemva kuzo zonke iimodeli zeMercedes-Benz ezixhotyiswe ngale njini.
Ukusebenzisa umzekelo Mercedes-Benz E-Class eya kuqala le 300 d injini, sinokulindela imisebenzi umdla kakhulu. Kwi-220 d version le modeli sele ikwazi ukukhawuleza ukusuka kwi-0-100 km / h ngemizuzwana eyi-7.4, kwaye ifike kwisantya esiphezulu se-242 km / h.
Ngoko ke kulindeleke ukuba le 300 d - eya kuba yeyona diesel inamandla e-four-cylinder emhlabeni - iya kukwazi ukutshitshisa la maxabiso. Ngaphezulu kwe-265 hp yamandla kunye ne-torque ekufuneka idlule i-650 Nm (i-EQ Boost mode) i-Mercedes-Benz E 300 d kufuneka ikwazi ukuzalisekisa i-0-100 km / h ngemizuzwana eyi-6.5 kwaye idlule i-260 km / h isantya esiphezulu ( ngaphandle komda wombane).
Ngaba ungathanda ukwazi iinkcukacha ezithe vetshe malunga nale njini?
