Mu cyerekezo kinyuranye n'ibirango bimaze gutangaza ko ishoramari rirangiye muri moteri nshya yo gutwika (reba urugero rwa Volkswagen cyangwa Audi), yariyandikishije muri “Amerika Patent and Trademark Office” (Ibiro bishinzwe ubucuruzi bwa Leta zunze ubumwe za Amerika) .), patenti aho tubona twin-turbo nshya V8 na Toyota.
Igiteye amatsiko, nkuko iyi patenti igaragara nyuma yumwaka ushize ibihuha bivuga ko ikirango cyabayapani cyiteguraga kureka iterambere ryubwoko bwa moteri bikangiza moteri ntoya (kandi yubukungu) V6.
Nubwo, nubwo ipatanti yerekana twin-turbo V8, bisa nkaho byibanda cyane kuri PCV nshya (Positive Crankcase Ventilation) itandukanya imikorere yayo ni ugutandukanya imyuka iva mumavuta ihunga hagati yurukuta rwimbere rwa silinderi nibice ya silinderi. piston (o-impeta).
Toyota twin-turbo V8 iraza?
Ibi ntibisobanura ariko ko Toyota idakora kuri twin-turbo V8. Ibishushanyo biri muri iyi patenti birerekana, kuva mugitangira (kandi muburyo busa nabana), nicyo kibanza cya moteri mumodoka izaba imbere ndende; kandi werekane neza turubarike ebyiri zashyizwe kuri moteri ya moteri, hagati yintebe zayo ebyiri zitunganijwe muri “V”.
Umwanya wawe urerekana igenamiterere "Ashyushye V" . Muyandi magambo, bitandukanye nibisanzwe mubindi moteri ya “V”, ibyambu bisohora (kumutwe wa silinderi) byerekeza imbere muri “V” aho kugirango bisohoke hanze, bituma habaho ubwubatsi bworoshye kandi bukaba hafi ya turbocharger na gaze ibyambu - kuvumbura inyungu zose zibi bikoresho.
Iyandikwa rya Toyota ryarimo ibishushanyo birambuye byerekana ibice bitandukanye bya moteri nshya ya V8.
Ariko, mubisobanuro byipatanti, Toyota iragaragaza ko, nubwo igishushanyo cyerekana twin-turbo V8, ibisubizo bimwe byasobanuwe (bijyanye no gutandukanya PCV) birashobora gukoreshwa kuri V8 hamwe na turbocharger imwe gusa, V6 cyangwa na bine- silinderi kumurongo (burigihe irengerwa na turbocharger).
Avuga kandi ko amashyanyarazi atagomba kuba ahagarikwa hagati yintebe ya silinderi, ariko ko ashobora gufata umwanya gakondo, hanze yintebe ya silinderi.
Ni ubuhe bwoko bwa moteri ishobora kugira?
Hanyuma, kubijyanye na moderi zishobora gukoresha iyi moteri, hariho "abakandida karemano", ntabwo cyane muri Toyota - birashoboka ko ishobora gukorera ikamyo nini ya Tundra cyangwa Land Cruiser - ariko muri Lexus. Muri byo F moderi yikimenyetso cyabayapani, aribyo IS, LS na LC.
Mugihe Lexus IS , moderi iherutse kuvugururwa bivuze ko yarangije umwuga wayo i Burayi, ariko muri Amerika, aho ikiri ku isoko, duherutse kubona moteri ya V8 isanzwe yifuzwa yashyizwe ahagaragara: IS 500 F Sport Performance. Muyandi magambo, haracyari umwanya wumusimbura nyawe kuri IS F.
Mugihe Lexus LS , mubisekuru byubu byatakaje V8 byahoraga biranga - ubu ifite V6 gusa -, twin-turbo V8 ishobora kuba igisubizo kiboneye kubarwanya nyamukuru bakomeje kwishimira ubu bwoko bwa moteri.
Ikintu kimwe gishobora kuvugwa kuri Lexus LC , coupé itangaje kandi ihinduranya nayo ifite na V8 yo mu kirere nka moteri yayo yo hejuru, twakundanye:
Birashoboka Lexus LC F ntagushidikanya gusiga "amazi muri nozzle". Nubwo bimeze bityo ariko, ni byiza gukomeza gutegereza "kugenzura" kubyerekeye moteri ishobora kubaho. Nyuma ya byose, kwandikisha ipatanti ntabwo bihwanye numusaruro.
