Hyundai / Kia R-Series injini - 2,0 CRDi (100, 135 kW) ndi 2,2 CRDi (145 kW)
Opanga magalimoto aku Korea omwe kale anali "mafuta" akutsimikizira kuti atha kupanganso injini yabwino ya dizilo. Chitsanzo chabwino ndi Gulu la Hyundai/Kia, lomwe lasangalatsa okonda mafuta ambiri ndi 1,6 (1,4) CRDi U-series. Ma injiniwa amadziwika ndi mphamvu zolimba, kugwiritsa ntchito mafuta oyenera komanso kudalirika, kuyesedwa nthawi. Magawo a CRDi a mndandanda wa D wopangidwa ndi kampani yaku Italy VM Motori munjira ziwiri zamagetsi (2,0 - 103 kW ndi 2,2 - 115 kW) adasinthidwa kumapeto kwa 2009-2010. Pa injini zatsopano za mapangidwe athu, otchedwa R-series.
Ma R ma motors amapezeka m'magulu awiri osunthira: 2,0 ndi 2,2 malita. Mtundu wocheperako umagwiritsidwa ntchito pama compact SUVs Hyundai ix35 ndi Kia Sportage, mtundu wokulirapo umagwiritsidwa ntchito m'badwo wachiwiri Kia Sorento ndi Hyudai Santa Fe. 2,0 CRDi imapezeka pamitundu iwiri yamagetsi: 100 ndi 135 kW (320 ndi 392 Nm), pomwe 2,2 CRDi imapereka 145 kW ndi torque yayikulu ya 445 Nm. Malinga ndi magawo omwe adalengezedwa, injini zonse ziwiri ndizabwino kwambiri mkalasi lawo (ma injini omwe ali ndi chodulira kuchokera pa turbocharger imodzi yokha).
Monga tafotokozera, injini zam'mbuyomu za D-series zidayamba kukhazikitsidwa m'magalimoto a Hyundai / Kia chakumayambiriro kwa zaka chikwi. Pang'ono ndi pang'ono, adadutsa magawo angapo a chisinthiko ndipo ntchito zawo zonse zinkayimira kuyendetsa bwino kwamoto. Komabe, iwo sanafike pamwamba pa kalasi chifukwa cha mphamvu zawo, komanso anali ndi mowa wambiri poyerekeza ndi opikisana nawo. Pazifukwa zomwezo, Hyundai / Kia Gulu anayambitsa injini kwathunthu kwa mapangidwe ake. Poyerekeza ndi omwe adatsogolera, mndandanda watsopano wa R uli ndi zosiyana zingapo. Yoyamba ndi makina khumi ndi asanu ndi limodzi a valve, omwe tsopano akulamulidwa ndi osati imodzi, koma ma camshafts awiri kudzera m'manja mwa rocker ndi ma pulleys ndi tappets hydraulic. Kuonjezera apo, ndondomeko ya nthawi yokha sichimayendetsedwanso ndi lamba wa mano, koma ndi maulalo azitsulo zachitsulo zomwe sizikusowa kukonzanso pansi pazikhalidwe zogwirira ntchito. Makamaka, unyolo umayendetsa camshaft-mbali yotulutsa, pomwe camshaft imayendetsa camshaft ya mbali.
Kuphatikiza apo, pampu yofunikira kuti igwiritse ntchito brake booster ndi vacuum actuators imayendetsedwa ndi camshaft ndipo si gawo la alternator. Pampu yamadzi imayendetsedwa ndi lamba lathyathyathya, pomwe m'badwo wam'mbuyomu galimotoyo idatetezedwa ndi lamba wanthawi ya mano, omwe nthawi zina amatha kuwononga - kuswa lamba ndi kuwonongeka kwakukulu kwa injini. The turbocharger ndi malo a DPF, pamodzi ndi makutidwe ndi okosijeni chosinthira chosinthira chomwe chimakhala pansi pa turbocharger, chasinthidwanso kuti mpweya wotulutsa uzikhala wotentha momwe mungathere komanso osazizira mosayenera monga m'badwo wakale (DPF inali pansi pa galimoto). Kutchulanso kusiyana kwakukulu pakati pa zosankha ziwiri za 2,0 CRDi. Amasiyana, monga mwachizolowezi, osati mu turbo pressure, jekeseni kapena pulogalamu ina yolamulira unit, komanso mu mawonekedwe osiyana a pisitoni ndi m'munsi psinjika chiŵerengero cha amphamvu Baibulo (16,0: 1 vs. 16,5: 1).
Jekeseni amachitidwa ndi 4th generation Common Rail system ndi Bosch CP4 jakisoni pampu. Majekeseni amayendetsedwa ndi piezoelectrically ndi kuthamanga kwakukulu kwa jekeseni mpaka 1800 bar, ndipo ndondomeko yonseyi imayang'aniridwa ndi Bosch EDC 17. Mutu wa silinda wokhawo umapangidwa ndi zitsulo zopepuka za aluminiyamu, chipikacho chimapangidwa ndi chitsulo choponyedwa. Ngakhale njira iyi ili ndi zovuta zina (nthawi yayitali yotentha kapena kulemera kwambiri), komano, chipangizo choterocho ndi chodalirika komanso chotsika mtengo kupanga. Injiniyo imakhala ndi valavu yotulutsa mpweya wotulutsa mpweya, womwe umayendetsedwa mosalekeza ndi mota yamagetsi, injini ya servo imakhalanso ndi udindo wosintha ma stator vanes mu turbocharger. Kuziziritsa bwino kwa mafuta kumaperekedwa ndi fyuluta yamafuta yokhala ndi chosinthira kutentha kwamadzi.
Zachidziwikire, kutsata muyezo wa Euro V emission, kuphatikiza zosefera, ndi nkhani. Popeza 2,2 CRDi injini analowa chitsanzo Sorento II mu 2009, Mlengi analandira Euro IV chivomerezo, kutanthauza kuti palibe fyuluta DPF. Chizindikiro chabwino kwa ogula, chomwe mwina sichiyenera. Ngakhale kulephera kapena moyo wa zosefera za DPF zakwera kwambiri, mtunda wautali kapena kuthamanga kwakanthawi kochepa kumakhudzabe kudalirika ndi moyo wa phindu la chilengedwechi. Choncho Kia analola injini bwino kwambiri ntchito m'badwo wachiwiri Sorente, ngakhale popanda nthawi yambiri DPF fyuluta. Chigawo choterechi chimakhala ndi chozizira chocheperako chotulutsa mpweya, chomwe m'mitundu yonse iwiri chimakhala ndi jumper (injini yozizira - yozizira). Kuphatikiza apo, mapulagi okhazikika achitsulo amagwiritsidwa ntchito m'malo mwa ceramic, omwe ndi okwera mtengo komanso osagwirizana ndi katundu wanthawi yayitali. M'makina amakono a dizilo, mapulagi onyezimira amayendetsedwanso kwakanthawi pambuyo poyambira (nthawi zina panthawi yonse yotentha) kuti achepetse kupangika kwa ma hydrocarbons osawotchedwa (HC) ndikuwongolera chikhalidwe cha injini. Kutenthetsanso ndikofunikira chifukwa cha kutsika kwapang'onopang'ono kwapang'onopang'ono, komwe kumapangitsanso kuti mpweya ukhale wochepa kwambiri panthawi ya kupanikizana. Ndiko kutentha kwapang'onopang'ono kumeneku komwe sikungakhale kokwanira kutulutsa mpweya wochepa wofunikira ndi miyezo yolimba kwambiri.
