Nkhani yaposachedwa yankhondo yamuyaya pakati pa osankhika apakati ku Germany

Ndibwino kuti pali zinthu zomwe tingadalire! Mwachitsanzo, mkangano umene wakhalapo kwa mibadwo yambiri ndi zaka zambiri. Mtundu umene ulipo pakati pa Mercedes C-Maphunziro ndi BMW posachedwapa anamasulidwa latsopano 3 Series. The Bavarian tsopano adzapikisana koyamba mu mtundu wa 320d wa dizilo motsutsana ndi C 220 d. Kotero - tiyeni tiyambe!

Monga magazini yaukadaulo yamagalimoto, njinga zamoto ndi zochitika zazikulu zaku motorsport pazaka 73 zapitazi, timapewa kunena za ziwerengero zaminda, nkhalango ndi malo odyetserako ziweto. Koma tsopano tiyeni tichite zosiyana. Osachepera chifukwa cha ulemu kwa iwo amene adakhulupirira (ngati adachitadi): Mitengo 90 biliyoni imakula m'nkhalango zaku Germany. Ambiri a iwo lerolino akuthamanga mozungulira gawo loyeserera mofulumira kwambiri modabwitsa. Kodi msewu suli wothamanga kuposa kale? Zikuwoneka kwa inu kuti chidule chachidule chimatha mwachangu kuposa masiku onse ndikusandulika njira yakumanzere mwachangu, phirilo litalowera mwachangu kuzama kwapanikizika, komwe njirayo imakwera kwambiri komaliza. ... Tinakumana ndi zodabwitsazi nthawi ina. Koma osati yapakatikati sedan ndi zinayi yamphamvu dizilo.

Apa, komabe, ma 320d amayandama m'nkhalango ndikuwonetsa kuti ku BMW, malonjezo akulu amatsatira zochitika zazikulu. Chaka chatha, pomwe tidadabwitsidwa momwe kagawo kakang'ono ka F30 kamakondera ngodya, BMW idatiuza kuti mtundu wotsatirawu utha kuyendetsa bwino. M'badwo wa G20, "troika" ibwerera kumayendedwe amasewera omwe sitimamva kuti tatayika. Zomwe a Bavaria adachita zidatsimikiziridwa ndi mayeso oyamba pa C-Class. Kenako mitundu iwiriyo idapikisana pamafuta a petulo ndi 258 hp, ndipo tsopano ayesa mitundu iwiri yofunikira kwambiri ndi injini za dizilo komanso kufalikira kwadzidzidzi.

Mapasa amatanthauza turbocharger ziwiri

BMW 3 Series inalandira injini ya dizilo ya malita awiri yokhala ndi mayina anyimbo B47TÜ1 (“TÜ1” imayimira technische Überarbeitung 1 – “technical processing 1”) ndi Twin Turbo. Mpaka pano, ndi dzina lopatsidwa kwa Twin Scroll turbocharger mu injini ya B47 320d, momwe mpweya wotayira wa ma silinda awiriwo umayendetsedwa mu mapaipi osiyana. Injini yatsopanoyi tsopano ili ndi ma turbocharger awiri: yaying'ono yothamanga kwambiri yomwe imayankha mwachangu, komanso yayikulu yotsika kwambiri yokhala ndi geometry yosinthika pakukoka kwautali.

Chifukwa ukadaulo wowonjezera umapereka mphamvu zochulukirapo kuposa njanji wamba, zotulutsa zoyambirira zimachepetsedwa, zomwe zimapangitsa kuyeretsa gasi kukhala kosavuta. Monga kale, BMW 320d imagwiritsa ntchito jekeseni wa urea wophatikizira ndi chothandizira chosungira cha NOx. M'galimoto yoyeserera, injiniyo imalumikizidwa ndi kufala kwama liwiro asanu ndi atatu. Kuchulukirachulukira kwa magiya onse ndi kuwongolera mwanzeru kumapangitsa kuti magwiridwe antchito, liwiro komanso chitonthozo. Choncho, chitsanzo BMW Imathandizira kwambiri mowiriza ndi wogawana, kunyamula liwiro mpaka 4000 rpm. Magiya odziyimira pawokha amayenda bwino - munthawi yake, mwachangu komanso bwino - zonse mokhazikika komanso mokakamiza.

Biturbo? Mercedes C 220 d inali ndi izi kale mu injini ya OM 651 yaposachedwa. Jakisoni wa Urea - monga BMW B654, injini ya OM 1449 ndi imodzi mwama injini a dizilo okhala ndi mpweya wabwino kwambiri.

BMW 320d ndi Mercedes C 220 d ndi pafupifupi ofanana kulemera, ndi mphamvu ndi makokedwe ziwerengero pafupifupi zofanana. Kutsogola kochepa kwa BMW mu zero mpaka 30 sprint kungakhale chifukwa cha magiya amfupi otsika. Kapena ayi. Mulimonsemo, magalimoto onse amakwaniritsa mayendedwe oterowo, omwe zaka 3 zapitazo sanali kupezeka kokha ku Mabaibulo apamwamba akale awo - M190 ndi Mercedes 2.5 E 16-XNUMX. Chofunikira kwambiri kuposa kusiyanasiyana kocheperako pamachitidwe amphamvu ndi momwe amagwiritsidwira ntchito.

Mercedes C 220 d imadalira kuti pambuyo poti turbo lag yaying'ono, pamakhala mphamvu yokwanira yoyambira nthawi zonse. Ngakhale pa 3000 rpm, injini imafika pachimake pamphamvu, zomwe zimawonjezera lingaliro lakukayikira kwawo kupita kumtunda wapamwamba. Zikatero, mayendedwe ake amakhala ovuta pang'ono. Pafupifupi nthawi yomweyo, makina othamanga othamanga asanu ndi anayi amalowererapo, omwe amagwirizana ndi dizilo ndi makokedwe awo kuposa momwe amapangira injini zamafuta. Chimodzi mwazomwe amamvetsetsa pakudziyimira pawokha ndikuti amasankha magiya oyenera bwino, koma nthawi zina amangonyalanyaza zoyendetsa zosayenera kudzera pazowongolera zida.

Izi zimawonjezera luso la kuyendetsa galimoto la C-Class. Mu Mercedes, simumadandaula za galimotoyo. M'malo mwake, galimoto imasamalira, nthawi zambiri pamtengo wowonjezera, kupereka kuyatsa koyenera ndi nyali za LED (halogen monga muyezo), ndipo poyendetsa mumsewu waukulu, tsatirani msewu, kuyang'ana malire a liwiro, mtunda ndi machenjezo a galimoto pamalo osawoneka. zoni. Koma koposa zonse, ena onse a 220 d amawonekera pachitonthozo chake. Ndi kuyimitsidwa kwa mpweya (ma euro 1666), "amatsitsimutsa" mabampu mumsewu ndipo ngakhale mumsewu wolimba wa Sport akukwera mosamala kuposa "troika" mu Comfort.

Zikuoneka kuti "azakhali abwino C" asanduka pang'ono kutha? Ayi, osati azakhali a Xi, koma nthano yeniyeni ya m'nkhalango yomwe imayandama mumsewu wokhotakhota! Mu C-Class, mphamvu sizokongoletsera, koma zenizeni. Izi makamaka chifukwa cha kayendedwe kabwino ka chiwongolero, kamene kamayankha ndendende, mwachindunji ndi bwino. Kuti izi zitheke, akatswiri opanga chitukuko apatsa chassis mawonekedwe osavuta kwambiri, okhala ndi malire ambiri pomwe dongosolo la ESP limayankha zofuna za dalaivala kumlingo wina osazindikira. Izi zimatsimikizira kuyendetsa kwachangu, kopanda nkhawa. Mu Mercedes C 220 d, mutha kukambirana mosavuta malo atsopano oyenda ndi mawu omveka bwino. Kapena yang’anani kutali nthaŵi ndi nthaŵi kuti muwonetsetse kuti teni peresenti ya mitengo ya m’nkhalangoyi ndi ya thundu.

Leipzig pamaso pa Hanover

Ndipo kodi tingachite chilichonse mu BMW 320d kupatula pagalimoto? Okondedwa, muli panjira yolakwika apa. Ndipo mumsewu wam'mbali wokhala ndi zokhota zambiri, komwe simukufuna kutembenuka ndikudutsa mumsewu wopangidwa bwino, wodzaza ndi infotainment kapena kufunafuna kumvetsetsa kwamphamvu kwambiri pakuwongolera mawu. Choncho, tidzafotokozera nthawi yomweyo: ponena za malo omwe akuyembekezeredwa, "troika" ndipamwamba pang'ono kuposa C-class, ndipo ponena za ubwino wa zipangizo zomwe zili pafupi nazo. Komanso, BMW amapereka nkhokwe wolemera mofanana wothandizira, koma koposa zonse, talente wapadera galimoto. Mwa njira, Troika si galimoto yoyendetsa galimoto. Zimafuna kuti mudzipereke nokha kwa izo.

Kuti izi zitheke, opanga mawonekedwewo adazisintha kuti zitheke kwambiri - makamaka mu mtundu wa M-Sport wokhala ndi chilolezo chocheperako, mabuleki amasewera, ma dampers osinthika komanso chiwongolero chamasewera osinthika. Imachita nthawi yomweyo kuchokera pamalo apakati, ngakhale pa liwiro lapamwamba, kuyenda pang'ono kwa chiwongolero ndikokwanira kusintha njira. Mukakoka kwambiri, mutha kusiya njira yakumanja m'malo mobwerera kunjira yanu mukadutsa. Koma ngakhale chiwongolero chimafuna kukhazikika pang'ono pamsewu waukulu, kuyendetsa galimoto kwapamsewu kumakhala kokhazikika.

Ma torsion-rod front axle (anti-deformation version ya MacPherson strut) ndi ekseli yolumikizana katatu amagwiritsa ntchito zida za BMW monga Z4. Ndicho chifukwa chake amayenda pafupifupi ngati masewera. Ngakhale mumayendedwe a "Comfort" a adaptive dampers, kuyimitsidwa kumakumana ndi kuuma kopitilira muyeso mpaka kugunda kwakufupi ndipo kumangotenga zazitali moyenera. Koma ponseponse, kukhazikika kolimba kumakhala koyenera kuwongolera molunjika, kogwira-mayankhidwe komanso kumbuyo kosewera pang'ono komwe kumatsalira koma kumabweretsa ESP motsimikiza kunjira yomwe ikufuna. Paziwonetsero zonse zosangalatsa zomwe atatuwa amavala, zikuwoneka kuti zikuyenda mwachangu kuposa C-Class, koma sizili choncho. Kutulutsa mtendere wamalingaliro, mtundu wa Mercedes nthawi zambiri umayenda mwachangu kuposa momwe mumamvera.

Mercedes C 220 d inamaliza kugoletsa mapointi asanu ndi atatu chifukwa chokhala ndi infotainment system yochepa kwambiri, zida zowonda komanso kugwiritsa ntchito mafuta ochulukirapo (6,7 vs. 6,5 malita). / 100 km mayeso avareji) amatanthauza zinthu ziwiri. Poyamba, dongosolo lake la infotainment silili lodzaza, kuti ndi lochepa pazida, komanso kuti limawononga ndalama zambiri. Ndipo kachiwiri, zitsanzo ziwirizi zikumenyana pamlingo wapamwamba kwambiri. Zikatero, zonse zimveka bwino, sichoncho? - amatha kugonjetsa mdani aliyense wobisala pakati pa mitengo ya m'kalasi mwawo.
