Lub cav Wankel yuav nyob mus ib txhis nrog Mazda. Nws yog lub npe no uas tau loj hlob, yuav luag tshwj xeeb, nyob rau tsib xyoos dhau los. Thiab lub lim tiam no ua kev zoo siab rau 50 xyoo txij li thaum pib ntawm kev lag luam ntawm Mazda Cosmo Sport (110S sab nraum Nyiv), uas tsis yog tsuas yog Japanese hom thawj lub tsheb kis las, tab sis kuj yog thawj tus qauv siv lub cav teb nrog ob lub rotors.
Cosmo tau los txhais ib feem tseem ceeb ntawm hom DNA. Nws yog tus thawj ntawm cov qauv ua cim zoo li Mazda RX-7 lossis MX-5. Mazda Cosmo Kev ua si nawv yog ib txoj kev nrog classic architecture: pem hauv ntej longitudinal engine thiab rear log tsav. Lub Wankel uas haum rau cov qauv no yog ib tug ntxaib-rotor nrog 982 cm3 nrog 110 horsepower, uas tau nce mus rau 130 hp nrog lub community launch, ib xyoos tom qab, ntawm tus qauv thib ob series.
Lub Wankel Engine Challenges
Cov kev sib tw loj yuav tsum tau kov yeej kom Wankel ua haujlwm tau zoo. Txhawm rau ua kom pom kev ntseeg tau ntawm cov thev naus laus zis tshiab, Mazda txiav txim siab koom nrog Cosmo Sport, xyoo 1968, hauv ib qho kev sib tw nyuaj tshaj plaws hauv Tebchaws Europe, 84 teev - Kuv rov hais dua -, 84 Teev Marathon de la Route ntawm Nürburgring circuit.
Ntawm 58 tus neeg koom yog ob Mazda Cosmo Kev Ua Si, xyaum ua qauv, txwv rau 130 horsepower los txhawb kev ua haujlwm ntev. Ib tug ntawm lawv ua nws mus rau qhov kawg, ua tiav nyob rau hauv 4 qhov chaw. Lwm qhov kev tshem tawm ntawm kev sib tw, tsis yog vim lub cav tsis ua haujlwm, tab sis vim yog lub qag puas tom qab 82 teev hauv kev sib tw.
Lub Cosmo Kev Ua Si muaj kev tsim tawm tsuas yog 1176 units, tab sis nws qhov cuam tshuam rau Mazda thiab lub cav teb yog qhov tseem ceeb. Ntawm tag nrho cov tuam txhab lag luam uas yuav daim ntawv tso cai los ntawm NSU - German tsheb thiab maus taus chaw tsim tshuaj paus - siv thiab tsim cov thev naus laus zis, tsuas yog Mazda pom kev ua tiav hauv kev siv.
Nws yog tus qauv no uas pib Mazda hloov pauv los ntawm cov chaw tsim khoom tseem ceeb ntawm cov tsheb me thiab kev lag luam tsheb mus rau ib qho ntawm cov khoom lag luam zoo siab tshaj plaws hauv kev lag luam. Txawm tias niaj hnub no, Mazda defies cov rooj sib tham hauv engineering thiab tsim, tsis muaj kev ntshai ntawm kev sim. Txawm hais tias rau cov thev naus laus zis - xws li qhov tseeb SKYACTIV - lossis rau cov khoom lag luam - xws li MX-5, uas tau zoo rov qab lub tswv yim ntawm cov kis las me me thiab pheej yig ntawm 60's.
Dab tsi yav tom ntej rau Wankel?
Mazda tau tsim ze li ob lab lub tsheb nruab nrog Wankel powertrains. Thiab nws tau ua keeb kwm nrog lawv txawm tias hauv kev sib tw. Los ntawm kev tswj hwm IMSA kev sib tw nrog RX-7 (hauv 1980s) mus rau qhov kev yeej ntawm 24 Teev ntawm Le Mans (1991) nrog 787B. Ib tug qauv nruab nrog plaub rotors, tag nrho 2.6 litres, muaj peev xwm xa ntau tshaj 700 horsepower. Lub 787B nqis mus rau hauv keeb kwm tsis yog tsuas yog ua thawj lub tsheb Asian los yeej cov kev sib tw legendary, tab sis kuj yog thawj qhov nruab nrog lub cav tig kom ua tiav qhov kev ua tau zoo.
Tom qab qhov kawg ntawm kev tsim khoom ntawm Mazda RX-8 hauv 2012, tsis muaj cov lus pom zoo rau hom cav no hauv hom. Nws rov qab los tau tshaj tawm thiab tsis lees paub ntau zaus. Txawm li cas los xij, zoo li qhov no yog qhov uas koj tuaj yeem rov qab los (saib qhov txuas saum toj no).
