Aliyense amene amakonda uinjiniya wamagalimoto ayenera kuvula chipewa chake kupita ku Mazda. Pokhala ndi zida zochepera kuposa opanga ambiri padziko lonse lapansi - omwe amathandizira mgwirizano wamagulu kuti akwaniritse chuma chambiri - Mazda ikupitiliza kupanga njira yawo pawokha. Imakulitsa nsanja zake, injini zake, mayankho ake. Ndipo zonsezi popanda kugwiritsa ntchito ntchito zamitundu ina. Zodabwitsa, sichoncho?
Koma Mazda anapita kutali. Pamene opanga ena onse kubetcherana pa kuchepetsa voliyumu ya injini (otchedwa kuchepetsa), ntchito supercharging ndi kachitidwe mwachindunji jakisoni, Mazda anapitiriza kusamuka kwa injini zake ndi anapezerapo m'badwo watsopano wa mafuta SKYACTIV injini mumlengalenga kuti kubetcherana mbali ina: kuchepetsa kutayika mphamvu. chifukwa cha kukangana ndi kuchuluka kwa compression ratio. Aliyense anati: njira si Mazda iyi. Koma nthawi inafika yotsimikizira mtundu wa Japan kuti ndi wolondola: pambuyo pake, kuchepetsa sikunali yankho.
OSATI KUPHONYEDWA: Zochitika zoyamba za Kia Stinger (yamoyo)
Zotsatira zake? Mazda akupitirizabe kuyika zolemba zonse zogulitsa malonda m'misika yonse ndikunena kuti galimoto isanakhazikitsidwe magetsi, pali njira yayitali yopitira mu injini zoyaka moto pakuchita bwino. Monga tidanenera sabata ino, a Mazda akufuna kukwezanso mipikisano.Monga?
Kukhazikitsa mum'badwo wotsatira wa injini zamafuta a SKYACTIV (omwe atha kukafika pamsika koyambirira kwa 2018) ukadaulo wa HCCI, womwe umayimira "Homogenous Charge Compression Ignition", kapena "Ignition by compression with homogeneous charge". Ndi ukadaulo uwu, kuyatsa kwamafuta kumatheka kudzera pakuponderezedwa kwakukulu kwa injini, ndikuchotsa mapulagi achikhalidwe kuti ayambitse kuphulika kosakanikirana. Kapena m'mawu ena, kupanikizika mu osakaniza kotero kuti kumayambitsa kuyatsa kwake.
Kwenikweni, izi ndi zomwe zimachitika kale mu injini za Dizilo, zomwe zimakhala zogwira mtima kwambiri kuposa injini zamtundu wa petulo pogwiritsa ntchito mphamvu, koma zomwe zimawononga kwambiri (chifukwa cha mpweya wopangidwa ndi kuyaka kwa dizilo).
Poyerekeza ndi injini za dizilo, ubwino wina wa injini za HCCI ndikuti safuna jekeseni wachindunji kapena masitima apamtunda wamba: mafuta amawathira muchipinda choyaka moto pang'ono komanso mochulukirapo - chinthu chofunikira kwambiri pakuwotcha mafuta mofanana. Onani chithunzi pansipa:
Mitundu ingapo yayesera kale kugwiritsa ntchito lusoli mu injini zawo zopanga: Nissan, Opel (GM), Mercedes-Benz ndi Hyundai. Onse anayesa koma palibe chomwe chinapambana.
Zikuoneka kuti Mazda anakwanitsa kuonjezera psinjika chiŵerengero cha injini HCCI ake mtengo kwambiri kuti ayenera kukhala pafupi 18:1. Poyerekeza, injini za dizilo zimakhala ndi chiŵerengero chapakati cha 16: 1, pamene mu injini zamtundu wa mafuta zimasiyana pakati pa 9: 1 ndi 10.5: 1 (malingana ndi mlengalenga kapena turbo).
Zindikirani: Chiŵerengero cha kuponderezana chimatanthawuza kuchuluka kwa kuchuluka kwa mafuta osakanikirana a silinda a mpweya mu chipinda choyaka moto chisanachitike kuphulika.
Ubwino wa dongosololi
Malinga ndi Mazda, kugwira ntchito ndi HCCI detonation m'malo mogwira ntchito ndi kuyatsa kwachikhalidwe kumachepetsa mpaka 30% kupanga NOx pakuyaka. Ndipo sikuti mpweya wokhawo umachepa, kumwa kumachepanso - zikhalidwe zomwe, monga tikudziwira, sizigwirizana.Kanema wa General Motors uyu akuwonetsa momwe dongosolo la HCCI limagwirira ntchito:
Mavuto, mavuto, mavuto
Mwachidziwitso, mfundoyi ndi yosavuta: chiŵerengero chapamwamba cha compression + homogeneous mix = chiwopsezo chokwanira komanso choyeretsa. Mfundoyi ndi yosavuta koma kuphedwa ndizovuta.
Kuti dongosololi lizigwira ntchito moyenera, mapulogalamu ndi hardware zomwe zimatha kuyang'anira kutentha mu chipinda choyaka moto, kuzungulira, jekeseni wamafuta ndi nthawi yotsegula ndi kutseka kwa ma valve ndizofunikira. Ndizovuta kwambiri kufananiza zinthu zonsezi munthawi yeniyeni, kupangitsa wogwiritsa ntchito kukhala wosangalatsa. Mitundu yambiri yayesera, palibe yomwe yapambana.
Vuto lina ndi ntchito yozizira, pamene chipinda choyaka moto sichifika pa kutentha kwabwino kwa ntchito, kuyaka kumakhala kosasintha.
Zikuoneka kuti Mazda, mosiyana zopangidwa kale, anakwanitsa kuthetsa mavuto onsewa. Monga? Posachedwa tipeza. Cholinga cha Mazda ndi chakuti m'badwo wotsatira wa Mazda3 udzabwera kale ndi injini za SKYACTIV HCCI, chitsanzo chomwe chiyenera kukhazikitsidwa kuyambira 2018.
Komabe, tikukhulupirira kuti Mazda sayiwalanso za injini iyi ...
