Mosiyana ndi mitundu yomwe yalengeza kale kutha kwa ndalama mu injini zoyaka moto (onani chitsanzo cha Volkswagen kapena Audi), idalembetsedwa ku "United States Patent ndi Trademark Office" (United States Patent ndi Trademark Office) . ), patent pomwe tikuwona mapasa-turbo V8 yatsopano ndi Toyota.
Chochititsa chidwi, monga patent iyi ikuwonekera pambuyo pa chaka chapitacho mphekesera kuti mtundu waku Japan ukukonzekera kusiya kukula kwa injini zamtunduwu kuwononga injini zazing'ono (komanso zachuma) V6 .
Komabe, ngakhale patent ikuwonetsa mapasa-turbo V8, ikuwoneka kuti ikuyang'ana kwambiri cholekanitsa chatsopano cha PCV (Positive Crankcase Ventilation) chomwe ntchito yake ndikulekanitsa mpweya wotulutsa kuchokera kumafuta omwe amatuluka pakati pa khoma lamkati la silinda ndi magawo. pisitoni (o-mphete).
Kodi Toyota twin-turbo V8 ikubwera?
Izi sizikutanthauza, komabe, kuti Toyota sikugwira ntchito pawiri-turbo V8. Zithunzi zomwe zili mu chiwonetsero ichi chovomerezeka, kuyambira pachiyambi (ndi m'njira yofanana ndi ya mwana), yomwe ndi malo a injini m'galimoto yomwe idzakhala kutsogolo kwautali; ndikuwonetsa momveka bwino ma turbocharger okwera pamakina a injini, pakati pa mabenchi ake awiri okonzedwa mu "V".
Malo anu akuwonetsa zochunira "Hot V" . Mwanjira ina, mosiyana ndi momwe zimakhalira mu injini zina za "V", ma doko otulutsa (pamutu wa silinda) amaloza mkati mwa "V" m'malo mwakunja, zomwe zimapangitsa kuti pakhale mawonekedwe ophatikizika komanso kuyandikira kwakukulu pakati pa ma turbocharger ndi utsi. madoko - pezani zabwino zonse za kasinthidwe uku.
Kulembetsa patent kwa Toyota kumaphatikizapo zojambula zatsatanetsatane zomwe zikuwonetsa magawo osiyanasiyana a injini yatsopano ya V8.
Komabe, m'mafotokozedwe a patent, Toyota ikuwonetsa kuti, ngakhale fanizo likuwonetsa mapasa-turbo V8, njira zomwezo zomwe zafotokozedwa (zokhudzana ndi olekanitsa PCV) zitha kugwiritsidwa ntchito ku V8 yokhala ndi turbocharger imodzi, V6 kapena ngakhale zinayi- silinda pamzere (nthawi zonse imakhala ndi ma turbocharger).
Ananenanso kuti ma turbocharger sayenera kukhala pamtanda pakati pa mabenchi a silinda, koma amatha kukhala ndi chikhalidwe chambiri, kunja kwa benchi ya silinda.
Kodi injiniyi ingakhale ndi mitundu yanji?
Pomaliza, zamitundu yomwe ingagwiritse ntchito injiniyi, pali "okonda zachilengedwe", osati ku Toyota - mwina ikhoza kutumizira galimoto yayikulu Tundra kapena Land Cruiser - koma ku Lexus. Pakati pawo mitundu ya F ya mtundu waku Japan, womwe ndi IS, LS ndi LC.
Ngati Lexus IS , kukonzanso kwaposachedwa kwachitsanzo kunatanthauza kutha kwa ntchito yake ku Ulaya, koma ku US, komwe kumagulitsidwabe, posachedwapa tawona injini ya V8 yodziwika bwino ikuwululidwa: IS 500 F Sport Performance. Mwanjira ina, pali mwayi woti wolowa m'malo weniweni wa IS F.
Ngati Lexus LS , omwe m'badwo wamakono adataya V8 yomwe nthawi zonse imadziwika - tsopano ili ndi V6 yokha -, mapasa-turbo V8 akhoza kukhala yankho loyenera kwambiri kwa otsutsa ake akuluakulu omwe akupitiriza kusangalala ndi mtundu uwu wa injini.
Zomwezo zikhoza kunenedwa za Lexus LC , coupé yodabwitsa komanso yosinthika yomwe pakadali pano ilinso ndi V8 yam'mlengalenga ngati injini yake yapamwamba, yomwe tidakondana nayo:
Chotheka Lexus LC F mosakayikira chimasiya "madzi mumphuno". Komabe, ndikofunikira kusunga ziyembekezo "zoyendetsedwa" za kuthekera kwa injini iyi kukhalapo. Kupatula apo, kulembetsa patent sikufanana nthawi zonse ndi kupanga.
