Mercedes-Benz sakhulupirira mafuta opangira, koma akupitiriza kukhulupirira injini za dizilo. Kuphatikiza pa kuyika magetsi, mtundu waku Germany ukupitilizabe kuyikapo ndalama pakuwotcha uku kuti akhazikitse zitsanzo zake.
Chifukwa chake, ndikufika kwa Mercedes-Benz E-Class yatsopano (m'badwo wa W213) pamsika - yomwe idasinthidwa pang'ono chaka chino - mtundu wa "vitaminized" wa injini yodziwika bwino ya OM 654 (220 d) nayonso kufika.
Choyambitsidwa mu 2016, injini iyi ya 2.0-lita, 4 silinda, aluminiyamu-block tsopano ikusintha: OM654 M.
Chatsopano ndi chiyani mu OM 654 M
Chotchingacho ndi chofanana ndi OM 654, koma zotumphukira ndizosiyana. OM 654 M tsopano ikupereka mphamvu 265 hp motsutsana ndi 194 hp ya m'badwo woyamba (yomwe idzapitirizabe kukhalapo mu E-Class range) zomwe zimayiyika ngati dizilo yamphamvu kwambiri padziko lonse lapansi.Makanema okhala ndi injini ya OM 654 M adzagulitsidwa ndi mawu a 300 d
Kuonjezera mphamvu ndi 70 hp, kuchokera ku chipika chokhala ndi malita 2.0 okha ndi masilinda anayi, kusintha komwe kunagwiritsidwa ntchito pa OM 654 kunali kwakukulu:
- Crankshaft yatsopano yokhala ndi sitiroko yayikulu (94 mm) zomwe zimapangitsa kuti anthu asamuke mpaka 1993 cm3 - pamaso pa 92.3 mm ndi 1950 cm3;
- Kuthamanga kwa jakisoni kudakwera kuchokera ku 2500 mpaka 2700 bar (+200);
- Mitundu iwiri ya geometry turbos yokhala ndi madzi;
- Plungers okhala ndi Nanoslide anti-friction treatment ndi ma ducts amkati odzaza ndi sodium alloy (Na).
Monga ambiri adzadziwa, sodium (Na) ndi chimodzi mwa zitsulo ntchito kwambiri mu firiji kachitidwe zomera mphamvu nyukiliya chifukwa cha makhalidwe ake: bata ndi kutentha dissipation mphamvu. Mkati mwa OM 654 M chitsulo chamadzi ichi chidzakhala ndi ntchito yofanana: kuteteza galimoto kuti isatenthedwe, kuchepetsa kukangana ndi kuvala kwa makina.
Kuphatikiza pa ma turbos oziziritsidwa ndi madzi, ma pistoni okhala ndi ma ducts amkati okhala ndi sodium alloy (Na) ndi amodzi mwamayankho anzeru omwe amapezeka mu OM 654 M. Koma si iwo okha…
Pafupifupi kuvomerezedwa magetsi
Kuphatikiza pa zinthu zatsopanozi, OM 654 M imakhalanso ndi chithandizo chamtengo wapatali: dongosolo losakanizidwa la 48 V. Ukadaulo womwe m'tsogolomu uyenera kukhalapo mu injini zonse.
Ndi magetsi ofanana omwe ali ndi jenereta / choyambira ndi batire, yokhala ndi ntchito ziwiri zofunika:
- Kupanga mphamvu zopangira magetsi a galimoto (air conditioning, chiwongolero, kuyendetsa galimoto zothandizira) kutulutsa injini yoyaka moto kuchokera ku ntchitoyi, motero kuwonjezera mphamvu zake;
- Thandizani injini kuyaka mathamangitsidwe, kupereka kuwonjezeka osakhalitsa mphamvu mpaka 15 kW ndi 180 Nm makokedwe pazipita. Mercedes-Benz imatcha ntchitoyi EQ Boost.
Komanso pankhani yolimbana ndi mpweya, ntchito yayikulu idachitikanso kuti athetse mpweya wotulutsa mpweya pa OM 654 M.
Injiniyi tsopano imagwiritsa ntchito fyuluta yamakono (yokhala ndi chithandizo chapamwamba kuti muchepetse ma NOx deposits) ndi njira yambiri ya SCR (Selective Catalytic Reduction) yomwe imalowetsa Adblue (32.5% pure urea, 67.5% demineralised madzi) mu makina otulutsa mpweya kuti asinthe NOx (nitrogen oxides) kukhala nayitrogeni ndi madzi (nthunzi).
Kodi tingayembekezere chiyani kuchokera ku 300d?
Ikafika pamsika, OM 654 M idziwika ndi 300 d - ndizomwe tipeza kumbuyo kwamitundu yonse ya Mercedes-Benz yokhala ndi injini iyi.
Pogwiritsa ntchito chitsanzo cha Mercedes-Benz E-Maphunziro kuti kuwonekera koyamba kugulu injini 300 d, tingayembekezere zisudzo chidwi kwambiri. Mu mtundu wa 220 d chitsanzo ichi chatha kale kuthamanga kuchokera ku 0-100 km / h mu masekondi 7.4, ndikufika pa liwiro la 242 km / h.
Choncho kuyenera kuyembekezera kuti 300 d iyi - yomwe idzakhala dizilo yamphamvu kwambiri padziko lonse lapansi - idzatha kuthetsa makhalidwe amenewa. Ndi mphamvu yopitilira 265 hp ndi torque yomwe iyenera kupitilira 650 Nm (EQ Boost mode) Mercedes-Benz E 300 d iyenera kukwaniritsa 0-100 km/h mumasekondi 6.5 ndikupitilira 260 km / h liwiro lalikulu ( popanda malire amagetsi).
Kodi mukufuna kudziwa zambiri za injiniyi?
Dinani apa
Tisiyeni ndemanga ndikulembetsa ku njira ya Youtube ya Razão Automóvel. Posachedwa tisindikiza kanema komwe tikufotokozera zonse za OM 654 M iyi, dizilo yamphamvu kwambiri yama silinda anayi padziko lapansi.
