Masiku ano injini zamafuta amafuta zimagwira bwino ntchito 40% (zambiri, komabe, zili ndi mfundo zingapo pansipa), koma Nissan akuti ili ndi injini yoyaka mafuta yamkati yomwe imatha kufika 50%, mtengo wake wapamwamba kuposa wa injini za Dizilo. (omwe amakhala pakati pa 43-45%).
Kukhala ndi kutentha kwapamwamba kwambiri - kugwiritsa ntchito mwayi wa kutembenuka kwa mphamvu zowonongeka kuchokera ku mankhwala omwe amawotcha kukhala mphamvu zamakina - ndikofunikira kuti muchepetse kugwiritsa ntchito / mpweya wa CO2. Komabe, kuti tikwaniritse mtengo wapamwamba wa 50%, Nissan anasintha cholinga cha injini yoyaka moto.
Cholinga chatsopanochi sichikugwiranso ntchito ngati chowongolera galimoto (komwe chimalumikizidwa ndi mawilo) ndipo tsopano chimangogwira ntchito ngati jenereta (yosalumikizidwa ndi mawilo) yamphamvu yamagetsi oyendetsa magetsi.
Injini ya petulo yogwira ntchito bwino… yamagetsi
Ndiye n'zosadabwitsa kuti chilengezochi chinabwera motengera luso la Nissan la e-MPOWER (teknoloji yosakanizidwa), yomwe imatumikira kale zitsanzo monga Note ndipo idzagwiritsanso ntchito Nissan Qashqai ya m'badwo wachitatu.Monga tanena kale kangapo, mitundu ya Nissan e-POWER ndi magalimoto amagetsi. Komabe, mphamvu zamagetsi zomwe amafunikira kuti azigwira ntchito sizimachokera ku batri lalikulu, lolemera komanso lokwera mtengo, koma kuchokera ku injini yoyaka mkati yomwe imatenga udindo wa jenereta. Palinso batri, ndizowona, koma ndizochepa kwambiri, zomwe zimatumikira kusunga mphamvu zomwe zimapangidwa ndi injini yotentha.
STARC, injini yachitsanzo
Pokhala jenereta chabe, ndizotheka kuchepetsa magwiridwe antchito a injini ya kutentha kumayendedwe ake abwino kwambiri a kasinthasintha ndi katundu. Ndilo sitepe yoyamba kukwaniritsa 50% kutentha kwachangu. Nissan tsopano akuwonetsa masitepe otsatirawa kuti akwaniritse cholinga chofuna chotere, pansi pa chitukuko cha m'badwo wotsatira wa ukadaulo wa e-MPOWER, zomwe zidapangitsa kuti pakhale injini yofananira, STARC.
Lembetsani ku kalata yathu yamakalata
STARC ndi chidule cha "njira yoyatsira yolimba, yopunduka komanso yotambasulidwa moyenera" - ngakhale nditafotokozera izi, tinali otayika pang'ono ... Malinga ndi Nissan, titha kumasulira izi momasuka kukhala ngati "chipinda choyatsira cholimba, chopangidwa mwapadera komanso chowonjezera. ” .
Kufotokozera tanthauzo la zonsezi, ntchito ya injiniya Nissan kwenikweni lolunjika pa kufulumizitsa otaya osakaniza mafuta-mpweya mpweya osakaniza mu yamphamvu pa poyatsira, amene adzalola kuyaka wathunthu wa osakaniza mafuta. ndi chiŵerengero chapamwamba cha kuponderezana.
Chinachake chomwe sichinatheke kukwaniritsa mu injini ya kutentha yomwe imagwiritsidwa ntchito ngati propeller. Iyenera kuyankha kusinthasintha kosalekeza kwa katundu ndi mphamvu pa mphindi iliyonse (kuthamanga, kutsika, kutsetsereka), zomwe zimafuna kusagwirizana pazigawo zake zogwirira ntchito (kusakaniza kumayenda mu silinda, nthawi yoyatsira ndi chiŵerengero cha kuponderezana). Kuchita kwake bwino kumasokonekera.
Zopinga zonsezi zimatha pamene injini ya kutentha imakhala jenereta, yomwe imayamba kugwira ntchito pokhapokha mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. mpweya.
Zotsatira za mayesero oyambirira a chitukuko pa injini ya multicylinder zikulonjeza. Kuchita bwino kwa 43% kunakwaniritsidwa pogwiritsa ntchito njira ya dilution ya EGR (exhaust gas recirculation valve) ndi 46% pogwiritsa ntchito mafuta osakanikirana a mpweya (mwachitsanzo, kusakaniza komwe kuli mpweya wochuluka kuposa mafuta poyerekezera ndi kusakaniza koyenera kwa kuyaka kwathunthu kwamafuta).
Kutentha kwa 50% kwa injini yatsopano ya STARC kumatheka pamene njirazi zikuphatikizidwa ndi matekinoloje obwezeretsa kutentha kwa zinyalala ndi injini yomwe ikuyenda mosalekeza komanso mozungulira. Tsopano yatsala pang'ono kudikirira kuti injini yapadera iyi ikhazikitsidwe.
Toshihiro Hirai, Wachiwiri kwa Purezidenti, Electric Car Engineering Division ndi Powerplants ku Nissan Motor Co. Ltd"Pofuna kukwaniritsa kusalowerera ndale kwa mpweya m'moyo wazinthu zake mpaka 2050, Nissan ikufuna kupatsa mphamvu pofika kumayambiriro kwa 2030s mitundu yonse yatsopano yomwe idakhazikitsidwa m'misika yayikulu yapadziko lonse lapansi. Njira yopangira magetsi ya Nissan imalimbikitsa chitukuko cha magetsi opangira magetsi ndi mabatire apamwamba kwambiri pamagalimoto amagetsi, ndi teknoloji ya e-MPOWER yomwe ikuyimira mzati wofunikira kwambiri panjirayi ".
