GM tsim 100 lab V8 cav
General Motors yuav tsim nws 100 lab tus me-thaiv V8 hnub no - 56 xyoo tom qab thawj lub tshuab ua haujlwm me me…
Txawm hais tias ntau xyoo dhau los ntawm kev kub siab rau cov cav loj loj raws li kev tso pa tawm thiab roj kev lag luam txoj cai nruj, lawv tseem raug tsim.
General Motors yuav tsim nws 100 lab tus me-thaiv V8 niaj hnub no - 56 xyoo tom qab thawj zaug tsim cov cav me me - hauv kev sib tw engineering rau lub ntiaj teb kev poob qis.
Chevrolet tau qhia txog qhov kev cog lus compact hauv xyoo 1955, thiab qhov tseem ceeb ntawm kev tsim khoom tuaj rau tib lub hlis uas lub tuam txhab ua kev zoo siab rau nws 100 xyoo.
Lub cav me me tau siv hauv GM tsheb thoob ntiaj teb thiab tam sim no siv hauv Holden / HSV, Chevrolet, GMC thiab Cadillac qauv.
"Lub thaiv me me yog lub cav uas ua rau muaj kev ua tau zoo rau tib neeg," David Cole, tus tsim thiab tus thawj tswj hwm ntawm Automotive Research Center. Cole txiv, tus lig Ed Cole, yog Chevrolet tus thawj engineer thiab coj txoj kev loj hlob ntawm tus thawj me-block engine.
"Muaj qhov yooj yim elegant rau nws tus qauv tsim uas tam sim ntawd ua rau nws zoo thaum nws yog tshiab thiab tso cai rau nws kom vam meej ze li rau xyoo caum tom qab."
Lub cav tseem ceeb hauv kev tsim khoom niaj hnub no yog 475 kW (638 hp) supercharged me me thaiv LS9-lub zog qab Corvette ZR1-uas yog tes-them ntawm GM Assembly Center, sab qaum teb hnub poob ntawm Detroit. Nws sawv cev rau plaub tiam ntawm cov blocks me me thiab yog lub cav muaj zog tshaj plaws uas tau tsim los ntawm GM rau lub tsheb tsim khoom. GM yuav khaws lub cav ua ib feem ntawm nws cov keeb kwm sau.
Lub thaiv me me tau hloov kho thoob plaws hauv kev lag luam tsheb thiab dhau mus. Cov tshiab versions ntawm thawj Gen I cav tseem raug tsim rau marine thiab industrial siv, thaum "boxed" versions ntawm lub engine muaj los ntawm Chevrolet Performance yog siv los ntawm ntau txhiab tus neeg nyiam qws kub.
Lub 4.3-liter V6 siv nyob rau hauv ib co Chevrolet thiab GMC tsheb yog raws li ib tug me me thaiv, tsuas yog tsis muaj ob lub tog raj kheej. Tag nrho cov versions no pab txhawb rau 100 lab me me thaiv qhov tseem ceeb.
Sam Weingarden, tus thawj coj thiab tus thawj coj ua haujlwm thoob ntiaj teb ntawm Engine Engineering pab pawg tau hais tias "Qhov kev ua tiav epic no ua rau muaj kev vam meej engineering uas tau nthuav dav thoob ntiaj teb thiab tsim lub cim kev lag luam,"
"Thiab thaum lub zog tsim qauv tsim tau ua pov thawj tias nws muaj peev xwm hloov mus rau kev ua tau zoo, emissions thiab ntxuav cov kev xav tau ntau xyoo, qhov tseem ceeb tshaj, nws tau xa lawv nrog kev ua haujlwm zoo dua."
Cov cav tam sim no muaj cov txhuas lub tog raj kheej thaiv thiab lub taub hau hauv tsheb thiab ntau lub tsheb thauj khoom, pab txo qhov hnyav thiab txhim kho roj kev lag luam.
Ntau daim ntawv thov siv roj-txuag thev naus laus zis xws li Active Fuel Management, uas kaw plaub lub tog raj kheej nyob rau hauv qee yam kev tsav tsheb teeb pom kev zoo, thiab Lub Sijhawm Sib Nqus Valve. Thiab txawm tias lub xyoo, lawv tseem muaj zog thiab kev lag luam.
Lub 430-horsepower (320 kW) version ntawm Gen-IV LS3 lub cav me me yog siv nyob rau hauv 2012 Corvette thiab ceev nws los ntawm so mus rau 100 km / h hauv li plaub vib nas this, npog lub quarter mais hauv tsuas yog 12 vib nas this thiab mus txog saum ceev. Tshaj 288 km / h, nrog EPA-rated txoj kev loj roj kev lag luam ntawm 9.1 l / 100 km.
Weingarden hais tias "Lub cav me me ua kom muaj kev ua haujlwm tsis zoo," "Qhov no yog qhov quintessence ntawm lub cav V8 thiab cov lus dab neeg muaj txiaj ntsig ntau dua li qhov qub."
Lub lim tiam no, GM kuj tau tshaj tawm tias lub thib tsib-tiam subcompact engine nyob rau hauv txoj kev loj hlob yuav feature ib tug tshiab direct-injection combustion system uas yuav pab txhim kho efficiency nyob rau hauv lub tam sim no engine.
"Me me block architecture txuas ntxiv ua pov thawj nws qhov cuam tshuam hauv kev lag luam hloov zuj zus sai sai, thiab lub tshuab thib tsib yuav tsim los ntawm kev ua tau zoo nrog cov txiaj ntsig zoo," Weingarden hais.
GM tab tom nqis peev ntau dua $ 1 nphom hauv lub tshuab hluav taws xob me me tshiab, ua rau 1711 txoj haujlwm tsim lossis txuag tau.
Lub tshuab Gen-V yuav tsum nyob rau yav tom ntej thiab tau lees tias yuav muaj 110 hli qhov chaw, uas yog ib feem ntawm qhov me me block architecture txij thaum pib.
GM pib V8 txoj kev loj hlob tom qab Ntiaj Teb Tsov Rog II, tom qab tus thawj engineer Ed Cole tau tsiv mus rau Chevrolet los ntawm Cadillac, qhov chaw uas nws coj txoj kev loj hlob ntawm tus nqi V8 engine.
Cole pab neeg tau khaws cov qauv siv nyiaj siv ua haujlwm uas yog lub hauv paus ntawm Chevrolet lub inline-rau lub cav, nyiam hu ua Stovebolt.
Nws tau suav hais tias yog ib qho ntawm qhov muaj zog ntawm Chevrolet tsheb kab, txhawb lub tswv yim ntawm kev yooj yim thiab kev ntseeg tau. Cole tau sib tw nws cov engineers los ntxiv dag zog rau lub cav tshiab kom ua kom nws sib zog, tsis tshua kim thiab yooj yim rau kev tsim khoom.
Tom qab nws debut nyob rau hauv lub Chevy lineup nyob rau hauv 1955, lub tshiab V8 engine yog lub cev me, 23 kg sib zog thiab ntau zog tshaj lub rau lub tog raj kheej Stovebolt engine. Tsis tsuas yog nws yog lub cav zoo tshaj plaws rau Chevrolet, nws yog txoj hauv kev zoo tshaj plaws los tsim cov tshuab minimalist uas coj kom zoo dua ntawm cov txheej txheem tsim khoom zoo.
Tom qab tsuas yog ob xyoos ntawm kev ua lag luam, cov cav me me tau pib loj hlob tsis tu ncua nyob rau hauv cov nqe lus ntawm kev hloov pauv, lub zog thiab kev nce qib ntawm kev siv tshuab.
Nyob rau hauv 1957, ib tug neeg kho tshuab roj txhaj tshuaj version tau qhia, hu ua Ramjet. Tsuas yog cov chaw tsim khoom loj uas muab kev txhaj tshuaj roj thaum lub sijhawm yog Mercedes-Benz.
Cov tshuab hluav taws xob txhaj tshuaj tau raug txiav tawm hauv nruab nrab xyoo 1960, tab sis hluav taws xob tswj kev txhaj tshuaj hluav taws xob tau tshwm sim hauv cov pob me me hauv xyoo 1980, thiab Tuned Port Txhaj tau tsim tawm hauv xyoo 1985, teeb tsa cov qauv ntsuas.
Lub tshuab hluav taws xob tswj hluav taws xob no tau txhim kho nyob rau lub sijhawm thiab nws cov qauv tsim tseem siv tau rau feem ntau cov tsheb thiab cov tsheb loj tshaj 25 xyoo tom qab.
Lub 110mm qhov chaw ntawm lub me thaiv yuav yog ib tug cim ntawm lub me me blocks compact thiab sib npaug kev ua tau zoo.
Qhov no yog qhov loj me me uas lub cim III me me tau tsim hauv xyoo 1997. Rau xyoo 2011, qhov me me yog nyob rau hauv nws lub cim thib plaub, txhawb nqa Chevrolet cov tsheb loj tag nrho, SUVs thiab vans, tsheb loj nruab nrab, thiab kev ua haujlwm siab Camaro thiab Corvette tsheb. .
Thawj 4.3-liter (265 cu nyob rau hauv) cav nyob rau hauv 1955 tsim mus txog 145 kW (195 hp) nrog ib tug xaiv plaub-pas carburetor.
Niaj hnub no, 9-litre (6.2 cu. in.) supercharged me thaiv LS376 hauv Corvette ZR1 muaj 638 horsepower.
