"Lub tsheb hluav taws xob tsis yog tib lo lus teb," said Robert Davis, Mazda Senior Vice President ntawm lub rooj sib tham tsis ntev los no. "Peb yuav tsum ua haujlwm ntawm kev daws teeb meem zoo tshaj plaws rau cov neeg siv khoom thiab ib puag ncig ntawm lub hom phiaj sib xws thiab tsis yog phau ntawv qhia yuav ua li cas mus txog qhov ntawd," nws hais ntxiv.
Davis yog li thuam lub xeev cov kev txhawb nqa uas tau muab rau cov tsheb fais fab, xws li los ntawm kev txhawb siab rau cov se dawb lossis los ntawm lub luag haujlwm kom muaj 100% tsheb fais fab hauv qee lub khw, xws li California.
Nws tsis yog lub luag haujlwm ntawm lub xeev thiab cov tswj hwm los muab cov lus teb thev naus laus zis, tab sis yog los txhais cov hom phiaj. Xav txog European nom tswv thawj koom ruam ntawm Diesel kom txo qis CO2 emissions nyob rau hauv ob lub xyoos dhau los thiab cov txiaj ntsig nws tau muab, cov lus ntawm Robert Davis yuav tsum tau hnov.
"Ua ntej peb muab sijhawm, kev siv zog thiab cov nqi rau kev siv hluav taws xob, peb ntseeg tau tias lub tshuab hluav taws xob sab hauv hluav taws xob yog qhov tseem ceeb," nws xaus.
Yog li dab tsi yog qhov kev daws teeb meem?
Tsis yog. Mazda tsis tau kaw qhov rooj ntawm hluav taws xob thiab hybrids. Zoo li lwm cov tuam ntxhab, Mazda tseem tab tom mus rau qhov kev taw qhia ntawd. Daim ntawv pov thawj rau qhov no yog qhov sib sib zog nqus ntawm kev sib raug zoo nrog Toyota hauv kev tsim hluav taws xob thiab 100% hluav taws xob fais fab. Ua piv txwv, Mazda thawj lub tshuab hluav taws xob yuav tshwm sim hauv 2019.
Tab sis kom txog thaum hluav taws xob tau npaj los ua qhov chaw nruab nrab hauv kev lag luam tsheb - ob qho tib si ntawm kev siv thev naus laus zis / nqi thiab kev lag luam - nws yuav yog "qub" lub tshuab hluav taws xob sab hauv uas kev lag luam yuav nyob ntawm kom ua tau raws li cov hom phiaj ib puag ncig. Thiab txawm tias lub cav combustion muaj ntau tshaj 100 xyoo ntawm lub neej, tseem muaj chaw rau kev txhim kho.
Mazda twb tau qhia qhov no ib zaug nrog thawj tiam SKYACTIV xyaw. Lawv tsis quav ntsej txog kev lag luam tiam sis, tseem tshuav ib txwm xav tau thiab tsis txo qhov ntim, hais tias "tsis muaj" rau qhov tsis txaus ntseeg downsizing - saib kab lus ntawm no. Cov ntaub ntawv-tawg compression piv (14: 1) ntawm cov roj av Mazda no tso cai rau cov txiaj ntsig pom tseeb uas tsis txwv rau txoj kev xav.
Tam sim no Mazda tau tshaj tawm tias nws tuaj yeem ua tau zoo dua. Qhov thib ob tiam ntawm SKYACTIV roj av cav tshaj tawm efficiency nce ntawm 20 mus rau 30%, muab lawv nyob rau tib theem li diesel xyaw.
SKYACTIV-X, petrol npaum li diesel
Yuav ua li cas thiaj ua tau rau lub cav roj av kom ua tau raws li lub tshuab hluav taws xob? Cov tshuaj boils mus rau plaub tsab ntawv: HCCI , uas txhais tau hais tias compression ignition nrog homogeneous nqi. Nyob rau hauv luv luv, lub tshuab no tso cai rau ib tug roj av cav ignite nyob rau hauv lub tom ntej no lub sij hawm, thaum lub txim plugs cia li ua rau ib tug saw cov tshuaj tiv thaiv thiab nyob rau hauv ib tug ntau homogeneous txoj kev. Zoo li Diesel, vim muaj qhov sib piv siab, lub siab nyob rau hauv qhov sib tov yog xws li hais tias nws ua rau nws ignition.
Mazda tsis yog thawj zaug sim. Daimler thiab GM tau sim nws yav dhau los, tab sis nws yeej tsis tau dhau los ntawm "lab" theem. Lub "me" Mazda yuav yog thawj cov chaw tsim khoom los tso cov thev naus laus zis no hauv lub tsheb tsim khoom, hauv 2019. Lub hom phiaj tau txiav txim siab hu nws SKYACTIV-X.
Qhov sib txawv rau lwm lub cav uas tau ntsib compression ignition yog tias SKYACTIV-X khaws lub txim taws. Ntawd yog, lub cav yuav hloov pauv ntawm ob txoj kev ignition, xaiv qhov tsim nyog tshaj plaws nyob ntawm qhov xav tau. Yog li lub npe ntawm lub system: SCCI los yog Spark Controlled Compression Ignition.
Nyob rau hauv lwm yam lus, thaum loads tsawg lub ignition yuav nqa tawm los ntawm compression, ib yam li ib tug Diesel, thiab nyob rau hauv siab loads nws yuav tsum tau nqa tawm los ntawm lub txim plugs. Xws li lub kaw lus tso cai rau nce qhov tam sim no SKYACTIV cov ntaub ntawv compression piv ntawm 14: 1 mus rau qhov zoo tshaj plaws 18: 1. SKYACTIV-X, raws li Mazda, tso cai rau koj kom muaj qhov zoo tshaj plaws ntawm ob lub ntiaj teb.
Kiyoshi Fujiwara, Tus Thawj Coj ntawm MazdaQhov no ntshiv cua-roj sib tov uas yog lean heev rau combustion los ntawm lub txim taws, los ntawm txoj kev no yuav hlawv huv si thiab sai. Nws tso cai rau kev ua haujlwm thermal zoo dua, kev lag luam roj zoo dua thiab txo qis emissions ntawm nitrogen oxides (NOx).
Yog hais tias txog tam sim no Mazda tau tawm tsam supercharge - tsis suav cov Diesels, tsuas yog 2.5 ntawm CX-9 siv lub turbo -, SKYACTIV-X, ntawm qhov tod tes, yuav supercharged los ntawm lub neej ntawd. Ntxiv nrog rau qhov hluav taws kub compression, SKYACTIV-X yuav muaj lub compressor los pab hauv lub luag haujlwm kom nce roj kev lag luam. Lub hom Japanese cog lus tias muaj ntau lub cav, nrog kev hloov pauv ntawm ob txoj kev sib tw, nrog rau qhov muaj nuj nqis ntawm 10 thiab 30% siab dua li tam sim no SKYACTIV-G.
Sustainable Zoom-Zoom 2030
SKYACTIV-X yog qhov tseem ceeb ntawm lub hom phiaj kev ruaj ntseg tshiab tshaj plaws, uas yuav txhais tau lub sijhawm ntev kev tsim kho thev naus laus zis ntawm hom. Ntawm cov hom phiaj hauv txoj kev npaj no yog qhov kev txo qis ntawm qhov zoo-rau-log CO2 emissions li ntawm 50% los ntawm 2030 thiab 90% los ntawm 2050, piv rau 2010.
Hais txog kev ruaj ntseg, peb yuav pom i-ACTIVSENSE thev naus laus zis tau txuas ntxiv mus rau ntau cov qauv. Mazda tseem yuav siv cov thev naus laus zis rau kev tsav tsheb tsis muaj zog - Mazda Co-Pilot Concept -, xav kom cov no los ua tus qauv, nyob rau hauv tag nrho nws cov qauv, txij li xyoo 2025. Lub hom phiaj yog kom tshem tawm cov tsheb sib tsoo.
