Ngokuphambana nezinhlobo esezivele zimemezele ukuphela kokutshalwa kwezimali ezinjinini ezintsha ezivuthayo (bona isibonelo se-Volkswagen noma i-Audi), yabhaliswa "e-United States Patent and Trademark Office" (United States Patent and Trademark Office) . ), ilungelo lobunikazi lapho sibona khona i-twin-turbo V8 yakwaToyota.
Yini efisa ukwazi, njengoba leli lungelo lobunikazi livela ngemva konyaka odlule amahemuhemu okuthi uhlobo lwaseJapane lwalulungiselela ukushiya ukuthuthukiswa kwalolu hlobo lwezinjini ngokulimala kwezinjini ezincane (kanye nezomnotho) ze-V6 .
Nokho, naphezu kwelungelo lobunikazi elibonisa i-twin-turbo V8, ibonakala igxile kakhulu kusihlukanisi esisha se-PCV (Positive Crankcase Ventilation) umsebenzi waso uwukuhlukanisa amagesi e-exhaust kuwoyela aphuma phakathi kodonga lwangaphakathi lwesilinda namasegimenti. ye-cylinder piston (o-rings).
Ingabe i-Toyota twin-turbo V8 iyeza?
Lokhu akusho nokho ukuthi iToyota ayisebenzi nge-twin-turbo V8. Imifanekiso kulo mbukiso welungelo lobunikazi, kusukela ekuqaleni (futhi ngendlela ecishe ifane neyengane), okuyindawo yenjini emotweni ezoba ngobude bangaphambili; futhi ibonise ngokucacile ama-turbocharger amabili agibele ibhulokhi yenjini, phakathi kwamabhentshi ayo amabili ahlelwe ngo-“V”.
Indawo yakho iphakamisa isilungiselelo "Hot V" . Ngamanye amazwi, ngokungafani nalokho okuvamile kwezinye izinjini "V", izimbobo zokukhipha umoya (ekhanda lesilinda) zikhomba ngaphakathi "V" esikhundleni sangaphandle, okuvumela ukwakhiwa okuhlangene kanye nokusondelana okukhulu phakathi kwama-turbocharger kanye ne-exhaust. amachweba - thola zonke izinzuzo zalokhu kumisa.
Ukubhaliswa kwelungelo lobunikazi kwaToyota kuhlanganisa imidwebo enemininingwane ebonisa izingxenye ezihlukahlukene zenjini entsha ye-V8.
Kodwa-ke, encazelweni yobunikazi, iToyota iveza ukuthi, naphezu komfanekiso obonisa i-twin-turbo V8, izixazululo ezifanayo ezichazwe (ezihlobene nesihlukanisi se-PCV) zingasetshenziswa ku-V8 ene-turbocharger eyodwa kuphela, i-V6 noma ngisho ne-four- isilinda kulayini (ihlala ishajwe kakhulu ngama-turbocharger).
Uphinde athi ama-turbocharger akudingekile ukuba abe sebhulokhini phakathi kwamabhentshi angamasilinda, kodwa angathatha indawo yendabuko, ngaphandle kwebhentshi yesilinda.
Imaphi amamodeli engaba nawo le njini?
Okokugcina, mayelana namamodeli angasebenzisa le njini, kukhona "abantu bemvelo", hhayi kakhulu kwaToyota - mhlawumbe ingase inikeze iveni elikhulu i-Tundra noma i-Land Cruiser - kodwa kwaLexus. Phakathi kwabo amamodeli we-F omkhiqizo waseJapane, okuyi-IS, i-LS ne-LC.
Uma kwenzeka I-Lexus IS , ukulungiswa kwakamuva kwale modeli kusho ukuphela komsebenzi wayo e-Europe, kodwa e-US, lapho isakhangiswa khona, sisanda kubona kwembulwa injini eyi-V8 eshisekela ngokwemvelo: IS 500 F Sport Performance. Ngamanye amazwi, sisekhona indawo yomlandeli weqiniso we-IS F.
Uma kwenzeka Lexus LS , esizukulwaneni samanje esilahlekelwe yi-V8 ehlale igqama ngayo - manje isine-V6 kuphela -, i-twin-turbo V8 ingaba yimpendulo efanelekile ezimbangini zayo ezinkulu eziqhubeka nokujabulela lolu hlobo lwenjini.
Kungashiwo okufanayo mayelana Lexus LC , i-coupé emangalisayo ne-convertible okwamanje futhi ene-V8 yomoya njengenjini yayo ephezulu, esiyithanda kakhulu:
I-Lexus LC F engaba khona ngaphandle kokungabaza eshiya “amanzi emlonyeni”. Kodwa-ke, kuyatuseka ukugcina okulindelekile "kulawuliwe" mayelana nokwenzeka kokuba le njini ibe khona ngempela. Phela, ukubhalisa i-patent akuhambisani ngaso sonke isikhathi nokukhiqiza.
