AbakwaMercedes-Benz abakholelwa emafutheni okwenziwa, kodwa basaqhubeka nokukholelwa ezinjinini zikadizili. Ngaphezu kokufaka ugesi, uhlobo lwaseJalimane luyaqhubeka nokutshala imali kulo mjikelezo wokusha ukuze kuphile amamodeli alo.
Ngakho-ke, ngokufika kwe-Mercedes-Benz E-Class evuselelwe (isizukulwane se-W213) emakethe - esithuthuke kancane kulo nyaka - inguqulo "yenziwe ngevithamini" yenjini yedizili eyaziwa kakade i-OM 654 (220 d) izoba. nazo zifike.
Yethulwe ngo-2016, le njini engu-2.0 litre, four-cylinder, aluminium block manje isishintshashintsha: the OM654M.
Yini Okusha ku-OM 654 M
I-block iyafana ne-OM 654, kodwa ama-peripherals ahlukile. I-OM 654 M manje iletha amandla angu-265 hp ngokumelene ne-194 hp yesizukulwane sokuqala (esazoqhubeka nokuba khona ku-E-Class range) esibeka njengedizili enamandla kunawo wonke amacylinder amane emhlabeni.Izinhlobo zopopayi ezinenjini ye-OM 654 M zizomakethwa ngesifinyezo esingu-300 d
Ukwandisa amandla angaphezu kuka-70 hp, kusukela kubhulokhi enamalitha angu-2.0 kuphela amandla namasilinda amane, izinguquko eziqhutshwa ku-OM 654 zazijulile:
- I-crankshaft entsha ene-stroke ephakeme (94 mm) okuholela ekwandeni kokufuduka ku-1993 cm3 - ngaphambi kuka-92.3 mm no-1950 cm3;
- Ingcindezi yomjovo ikhuphuke isuka ku-2500 yaya ku-2700 bar (+200);
- Ama-turbos ama-geometry amabili apholile ngamanzi aguquguqukayo;
- Ama-plungers ane-Nanoslide anti-friction kanye namapayipi angaphakathi agcwele i-sodium alloy (Na).
Njengoba abaningi bezokwazi, i-sodium (Na) ingenye yezinsimbi ezisetshenziswa kakhulu ezinhlelweni zesiqandisi zezitshalo zamandla enyukliya ngenxa yezimpawu zayo: ukuzinza namandla okukhipha ukushisa. Ngaphakathi kwe-OM 654 M le nsimbi ewuketshezi izoba nomsebenzi ofanayo: ukuvimbela injini ekushiseni ngokweqile, ukunciphisa ukungqubuzana nokugqoka komshini.
Ngaphezu kwe-turbos epholile ngamanzi, ama-piston anemibhobho yangaphakathi ene-sodium alloy (Na) angesinye sezixazululo ezihlakaniphile kakhulu ezikhona ku-OM 654 M. Kodwa akubona bodwa...
Cishe ukufakwa kukagesi okuyimpoqo
Ngaphezu kwalezi zici ezintsha, i-OM 654 M iphinde ibe nosizo oluyigugu: i-mild-hybrid system 48 V. Ubuchwepheshe esikhathini esizayo esingekude kakhulu kufanele bube khona kuzo zonke izinjini.
Iwuhlelo lukagesi oluhambisanayo oluhlanganisa ijeneretha/isiqalisi nebhethri, nemisebenzi emibili ebalulekile:
- Khiqiza amandla ukuze unike amandla amasistimu kagesi emoto (i-air conditioning, isiteringi, izinhlelo zokusekela ukushayela) ukukhulula injini evuthayo kulo msebenzi, ngaleyo ndlela ukwandisa ukusebenza kahle kwayo kwamandla;
- Isiza injini evuthayo ekusheshiseni, inyusa isikhashana amandla afinyelela ku-15 kW kanye ne-torque engu-180 Nm. I-Mercedes-Benz ibiza lo msebenzi ngokuthi i-EQ Boost.
Futhi emkhakheni wokulwa nokukhishwa kwegesi, umsebenzi omkhulu wenziwa futhi ukwelapha amagesi okukhipha igesi ku-OM 654 M.
Le njini manje isebenzisa isihlungi sezinhlayiyana ezisezingeni eliphezulu (ngokwelashwa okungaphezulu ukuze kuncishiswe amadiphozithi e-NOx) kanye nohlelo lwe-SCR olunezigaba eziningi (Selective Catalytic Reduction) olujova i-Adblue (32.5% pure urea, 67.5% amanzi ancishisiwe) uhlelo lwe-exhaust lokuguqula i-NOx (i-nitrogen oxides) ibe yi-nitrogen namanzi (umusi).
Yini esingayilindela ku-300d?
Uma isifika emakethe, i-OM 654 M izobe seyaziwa nge-300 d — yilokho esizokuthola ngemuva kwazo zonke izinhlobo zakwaMercedes-Benz ezifakwe le njini.
Ngokusebenzisa isibonelo se-Mercedes-Benz E-Class ezoqala le njini engu-300 d, singalindela ukusebenza okuthakazelisayo kakhulu. Enguqulweni engu-220 d le modeli isivele ikwazi ukusheshisa isuka ku-0-100 km/h ngemizuzwana engu-7.4, futhi ifinyelele isivinini esingu-242 km/h.
Ngakho-ke kulindelekile ukuthi le 300 d - okuzoba idizili enamasilinda amane enamandla kakhulu emhlabeni - izokwazi ukushabalalisa la manani. Inamandla angaphezu kuka-265 hp kanye netorque okufanele idlule ku-650 Nm (EQ Boost mode) iMercedes-Benz E 300 d kufanele ikwazi ukugijima ku-0-100 km/h ngemizuzwana engu-6.5 futhi yeqe ku-260 km/h isivinini esiphezulu ( ngaphandle komkhawulo we-elekthronikhi).
