Chero ani anoda mota engineering anofanira kutora ngowani yake kuenda kuMazda. Iine zviwanikwa zvishoma kupfuura vagadziri vazhinji pasi rese - izvo zvinosimudzira kubatana kweboka kuti uwane hupfumi hwehukuru - Mazda inoenderera mberi kuronga nzira yayo yakazvimiririra. Inovandudza mapuratifomu ayo, injini dzayo, mhinduro dzayo. Uye izvi zvese pasina kushandisa masevhisi emamwe mabhureki. Zvinoshamisa, handizvo here?
Asi Mazda yakatoenda kure. Kana vamwe vese vanogadzira vachibhejera kudzikisa huwandu hweinjini (inonzi kudzikisira), vachishandisa supercharging uye yakananga jekiseni masisitimu, Mazda yakachengetedza kutamiswa kwemainjini ayo uye yakatanga chizvarwa chitsva chepeturu SKYACTIV injini dzemuchadenga dzinobheja kune imwe nzira: kuderedzwa kwekurasikirwa kwesimba. nekuda kwekukweshana uye kuwedzera kwekumanikidza reshiyo. Munhu wose akati: nzira haisi Mazda iyi. Asi nguva yakasvika yekuratidza kuti chiJapan chakarurama: shure kwezvose, kuderedza yakanga isiri mhinduro.
HAZVIFANIRI KUSHAIKWA: Maonero ekutanga eiyo itsva Kia Stinger (rarama)
Mhedzisiro? Mazda inoenderera mberi nekugadzirisa zvinyorwa zvekutengesa zvakakwana mumisika yose uye kutaura kuti kusati kwaiswa magetsi emotokari, kuchine nzira yakareba yekufamba mumajini ekupisa maererano nekushanda. Sekutaura kwatakaita svondo rino, Mazda inoda kusimudza mbambo zvakare.Kufanana?
Kuita muchizvarwa chinotevera cheSKYACTIV peturu injini (iyo inogona kusvika kumusika kutanga kwa2018) tekinoroji yeHCCI, inomiririra "Homogenous Charge Compression Ignition", kana "Ignition by compression with homogeneous charge". Neiyi tekinoroji, kupisa kwemafuta kunowanikwa kuburikidza nehupamhi hwekumanikidza rejini, kubvisa echinyakare spark plugs kutanga musanganiswa kuputika. Kana nemamwe mazwi, kudzvinyirirwa mumusanganiswa ndeyekuti inokonzera kupisa kwayo.
Chaizvoizvo, izvi ndizvo zvinotoitika mumajini eDiesel, ayo anoshanda zvakanyanya kupfuura echinyakare peturu injini maererano nekushandiswa kwesimba, asi izvo kune rumwe rutivi zvakanyanya kusvibisa (nekuda kwemagasi anogadzirwa nekupisa kwedhiziri).
Zvichienzaniswa neinjini dzedhiziri, imwe mukana weinjini dzeHCCI ndeyekuti haidi jekiseni rakananga kana masisitimu enjanji akajairika: mafuta anopfapfaidzwa mukamuri yekupisa muhuwandu hudiki uye zvakanyanya homogeneous - chinhu chakakosha chemafuta detonation zvakaenzana. Ona mufananidzo pazasi:
Mhando dzinoverengeka dzakatoedza kushandisa tekinoroji iyi mumainjini ekugadzira: Nissan, Opel (GM), Mercedes-Benz uye Hyundai. Vese vakaedza asi hapana akabudirira.
Sezviri pachena, Mazda akakwanisa kuwedzera compression reshiyo yayo HCCI injini kune yakanyanyisa kukosha inofanira kuva pedyo 18:1. Mukuenzanisa, injini dzedhiziri dzine avhareji yekumanikidza reshiyo ye16: 1, nepo mune zvechinyakare injini dzepeturu izvi zvakakosha zvinosiyana pakati pe9: 1 ne10.5: 1 (zvichienderana nekuti ari mumhepo kana turbo).
cherechedza: Compression ratio inoreva huwandu hwenguva iyo vhoriyamu yemhepo-mafuta musanganiswa inotsikirirwa mukamuri yekupisa isati yaputika.
Zvakanakira hurongwa uhu
Sekureva kweMazda, kushanda neHCCI detonation pachinzvimbo chekushanda nemagetsi echinyakare kunoderedza kusvika ku30% kugadzirwa kweNOx mukupisa. Uye haisi yekungobuda chete inodzikira, kushandiswa zvakare kunodzikira - kukosha izvo, sezvatinoziva, hazvina kuwirirana.Iyi vhidhiyo yeGeneral Motors inoratidza mashandiro anoita HCCI system:
Matambudziko, matambudziko, matambudziko
Nechepfungwa, musimboti wacho uri nyore: yakakwirira compression ratio + homogeneous musanganiswa = inoshanda uye yakachena kupisa. Nheyo yacho iri nyore asi kuuraya kwakaoma.
Kuti iyi system ishande nemazvo, software uye hardware inokwanisa kutarisa kupisa mukamuri yekupisa, kutenderera, jekiseni remafuta uye nguva yekuvhura nekuvhara yevhavha inodiwa. Zvakanyanya kuomarara kufananidza zvese izvi zvinhu munguva chaiyo, kuchengetedza mushandisi achinakidza. Mhando dzakawanda dzakaedza, hapana akabudirira.
Rimwe dambudziko nderekushanda kunotonhora, nepo kamuri yekupisa isingasviki kune yakakodzera tembiricha yekushanda, kupisa hakuna kurongeka.
Zvinoita sekuti Mazda, kusiyana nemhando dzatotaurwa, yakakwanisa kugadzirisa matambudziko ese aya. Kufanana? Tichakurumidza kuziva. Chinangwa cheMazda ndechekuti chizvarwa chinotevera cheMazda3 chichauya chakashongedzerwa neSKYACTIV HCCI injini, modhi yakarongerwa kutanga kutanga kwa2018.
Nekudaro, isu tinovimba kuti Mazda haikanganwe nezve injini iyi zvakare…
