GM idapanga ma injini 100 miliyoni a V8

General Motors ipanga V100 yake yaying'ono yokwana 8 miliyoni lero - patadutsa zaka 56 pambuyo pa injini yaying'ono yopangidwa ndi…

Ngakhale kwa zaka makumi ambiri akukakamizika kuyika injini zazikulu pamene kutulutsa mpweya ndi malamulo oyendetsera mafuta akuchulukirachulukira, akupangidwabe.

General Motors ipanga injini yake ya 100 miliyoni ya block V8 lero - patadutsa zaka 56 kuchokera pomwe idapanga injini yaying'ono ya block - muvuto laukadaulo pakuchepetsa kuchepa kwapadziko lonse lapansi.

Chevrolet idakhazikitsa chipika chophatikizika mu 1955, ndipo ntchito yofunika kwambiri yopanga idabwera mwezi womwewo pomwe mtunduwo udakondwerera zaka 100.

Injini yaying'ono ya block block yakhala ikugwiritsidwa ntchito m'magalimoto a GM padziko lonse lapansi ndipo pakadali pano imagwiritsidwa ntchito mumitundu ya Holden / HSV, Chevrolet, GMC ndi Cadillac.

"Chida chaching'ono ndi injini yomwe idabweretsa magwiridwe antchito apamwamba kwa anthu," atero a David Cole, woyambitsa komanso wapampando wa Automotive Research Center. Bambo a Cole, malemu Ed Cole, anali injiniya wamkulu wa Chevrolet ndipo anatsogolera chitukuko cha injini yaing'ono yoyambirira.

"Pali kuphweka kwabwino pamapangidwe ake omwe adapangitsa kuti ikhale yabwino pomwe inali yatsopano ndikupangitsa kuti izichita bwino pafupifupi zaka makumi asanu ndi limodzi pambuyo pake."

Injini yofunika kwambiri yomwe ikupangidwa lero ndi 475kW (638hp) chipika chaching'ono cha LS9-mphamvu kumbuyo kwa Corvette ZR1-yomwe imasonkhanitsidwa pamanja ku GM Assembly Center, kumpoto chakumadzulo kwa Detroit. Imayimira m'badwo wachinayi wa midadada yaying'ono ndipo ndi injini yamphamvu kwambiri yomwe GM idapangidwapo pamagalimoto opangira. GM idzasunga injini ngati gawo lazosonkhanitsa zakale.

Chotchinga chaching'ono chasinthidwa mumakampani onse amagalimoto ndi kupitirira apo. Mitundu yatsopano ya injini yoyambirira ya Gen I ikupangidwabe kuti igwiritsidwe ntchito panyanja ndi m'mafakitale, pomwe ma injini a "boxed" omwe amapezeka ku Chevrolet Performance amagwiritsidwa ntchito ndi zikwizikwi za okonda ndodo zotentha.

V4.3 ya 6-lita yomwe imagwiritsidwa ntchito m'magalimoto ena a Chevrolet ndi GMC imakhazikika pa chipika chaching'ono, chopanda masilinda awiri okha. Mabaibulo onsewa amathandizira pakupanga midadada yaying'ono ya 100 miliyoni.

"Kupambana kwakukulu uku kukuwonetsa kupambana kwaukadaulo komwe kwafalikira padziko lonse lapansi ndikupanga chithunzi cha mafakitale," adatero Sam Weingarden, wamkulu wamkulu komanso mutu wapadziko lonse lapansi wa gulu la Engine Engineering.

"Ndipo ngakhale mawonekedwe olimba a compact unit atsimikizira kuti amatha kusintha magwiridwe antchito, mpweya wotulutsa mpweya komanso zofunikira zoyeretsera pazaka zambiri, chofunikira kwambiri, amazipereka bwino."

Ma injini tsopano amakhala ndi midadada ya aluminiyamu ya silinda ndi mitu m'magalimoto ndi magalimoto ambiri, zomwe zimathandiza kuchepetsa kulemera komanso kukonza mafuta.

Mapulogalamu ambiri amagwiritsa ntchito matekinoloje opulumutsa mafuta monga Active Fuel Management, yomwe imatseka masilinda anayi pansi pamikhalidwe ina yonyamula katundu, ndi Variable Valve Timing. Ndipo ngakhale kwa zaka zambiri, iwo akadali amphamvu komanso otsika mtengo.

Mtundu wa 430-horsepower (320 kW) wa injini yaying'ono ya Gen-IV LS3 imagwiritsidwa ntchito mu Corvette ya 2012 ndikuifulumizitsa kuchoka pampumulo kupita ku 100 km / h pafupifupi masekondi anayi, imatha mtunda wa makilomita oposa 12. imafika pa liwiro lapamwamba. kupitirira 288 km/h, ndi EPA-ovoteledwa Highway mafuta chuma cha 9.1 l/100 Km.

"Mainjini ang'onoang'ono amaonetsetsa kuti magwiridwe antchito akuyenda bwino," akutero Weingarden. "Uku ndiye quintessence ya injini ya V8 komanso nthano yamoyo yofunika kwambiri kuposa kale."

Sabata ino, a GM adalengezanso kuti injini yachisanu ya m'badwo wachisanu yomwe ikupangidwa ikhala ndi makina oyatsa jekeseni omwe angathandize kukonza bwino injini yamakono.

"Zomangamanga zazing'onoting'ono zikupitiliza kutsimikizira kufunika kwake mumakampani omwe akukula mwachangu, ndipo injini ya m'badwo wachisanu idzapanga magwiridwe antchito ndi zopindulitsa zazikulu," akutero Weingarden.

GM ikuyika ndalama zoposa $1 biliyoni popanga injini zazing'ono, zomwe zimapangitsa kuti ntchito 1711 zipangidwe kapena kupulumutsidwa.

Injini ya Gen-V ikuyembekezeka posachedwapa ndipo ikutsimikiziridwa kukhala ndi malo oboola 110mm, omwe akhala mbali ya zomangamanga zazing'ono kuyambira pachiyambi.

GM inayamba chitukuko cha V8 pambuyo pa nkhondo yachiwiri ya padziko lonse, pambuyo pa injiniya wamkulu Ed Cole atasamukira ku Chevrolet kuchokera ku Cadillac, kumene adatsogolera chitukuko cha injini ya V8 yoyamba.

Gulu la Cole linasungabe mapangidwe a valve apamwamba omwe anali maziko a injini ya Chevrolet ya inline-six, yomwe imatchedwa Stovebolt.

Ankaonedwa kuti ndi imodzi mwa mphamvu za mzere wa galimoto ya Chevrolet, kulimbikitsa lingaliro la kuphweka ndi kudalirika. Cole adatsutsa akatswiri ake kuti alimbikitse injini yatsopano kuti ikhale yowonjezereka, yotsika mtengo komanso yosavuta kupanga.

Pambuyo kuwonekera koyamba kugulu ake mu mndandanda wa Chevy mu 1955, latsopano injini V8 anali ang'onoang'ono thupi, 23 kg mbandakucha ndi wamphamvu kuposa silinda silinda Stovebolt injini. Sikuti inali injini yabwino kwambiri ya Chevrolet, inali njira yabwino kwambiri yopangira ma injini a minimalist omwe adagwiritsa ntchito njira zopangira zopangira.

Patangotha ​​​​zaka ziwiri zokha pamsika, injini zazing'ono zama block zayamba kukula pang'onopang'ono ponena za kusamuka, mphamvu ndi kupita patsogolo kwaukadaulo.

Mu 1957, makina opangira jakisoni wamafuta adayambitsidwa, otchedwa Ramjet. Wopanga wamkulu yekhayo yemwe amapereka jakisoni wamafuta panthawiyo anali Mercedes-Benz.

Jakisoni wamafuta amakina adazimiririka chapakati pazaka za m'ma 1960, koma jakisoni wamafuta amagetsi adayamba kuwonekera m'ma 1980s, ndipo Tuned Port Injection idakhazikitsidwa mu 1985, ndikuyika chizindikiro.

Dongosolo la jakisoni wamafuta loyendetsedwa ndimagetsili lakhala likuyenda bwino pakapita nthawi ndipo mapangidwe ake akugwiritsidwabe ntchito pamagalimoto ambiri ndi magalimoto opepuka pazaka 25 pambuyo pake.

Mabowo a 110mm a chipika chaching'onocho atha kukhala chizindikiro chakuchita bwino kwa chipikacho.

Uwu unali kukula kwake komwe kanyumba kakang'ono ka kam'badwo ka III kanapangidwa mu 1997. Kwa 2011, chipika chaching'onocho chili m'badwo wake wachinayi, choyendetsa magalimoto amtundu wa Chevrolet, ma SUV ndi ma vani, magalimoto apakatikati, komanso magalimoto apamwamba a Camaro ndi Corvette. .

Injini yoyamba ya 4.3-lita (265 cu in) mu 1955 idapanga mpaka 145 kW (195 hp) yokhala ndi carburetor ya migolo inayi.

Masiku ano, 9-lita (6.2 cu. in.) supercharged yaing'ono chipika LS376 mu Corvette ZR1 ali 638 ndiyamphamvu.
