Kukho i-slogan yentengiso eyaziwayo eNyakatho Melika: "Ewe, ine-Hemi" .Kwaye la magama amahlanu anele ukwenza abalandeli beemoto zokusebenza bacace ngokukhawuleza.
Enyanisweni, oku akusiyo umbuzo olula ukuwuphendula, kuba ngokwenene iinjini ezine zeentsapho zeChrysler zonke zithwala ileyibhile yokuthengisa iHemi.Omnye wabo yintsapho yezityalo zamandla ezikhethekileyo e-Australia.
Kwangaxeshanye, yintoni i-injini yesiqingatha (ngonobumba abancinci “h”)?Yonke iyabila ukuya kutsho kubume begumbi lokutsha; isithuba kwi-injini apho umoya kunye namafutha okwenene zitshisa ukuvelisa i-torque, leyo ingamandla ajika i-crankshaft kwaye ekugqibeleni amavili emoto.
Uthetha ukuthini uHemi? Ngokusisiseko, imilo yeli gumbi lokutsha ifana nesiqingatha sebhola yentenetya, okanye irhatyana, ngoko i-hemispherical. ukusetyenziswa kweevalvu ezinkulu zokungena kunye nokukhupha (iivalvu ezinkulu zithetha umoya kunye namafutha amaninzi ngaphakathi nangaphandle).
Uyilo olunqamlezayo apho umoya kunye namafutha angena ukusuka kwelinye icala legumbi lokutsha kunye nokuphuma kwelinye icala kwakhona kunceda ukuphucula ukusebenza kakuhle.
I-Chrysler ayisiyiyo kuphela umenzi wemoto ukusebenzisa igumbi lokutshisa i-hemispherical, kodwa ngenxa yomlingo wokuthengisa, iye yaba lolona phawu lusondele kakhulu kuyilo.
Kwangoko ngo-1907, uFiat waqaphela ukubakho koyilo lwesiqingatha kwaye wayizisa kumzila ngemoto yakhe yeGrand Prix.
Okubangel 'umdla kukuba, ukufika kweentloko ze-valve ezininzi zacotha ukuveliswa kweenjini ezinoyilo lwe-hemispherical ngenxa yokuba zifaneleke ngakumbi kwiivalvu ezimbini ezinkulu kuneevalvu ezine ezincinci.
Kodwa ekuhambeni kweminyaka, abavelisi abaninzi baye basebenzisa i-semi-design, nokuba abazange bayibize ngolo hlobo kuba besoyika ukunika uChrysler isohlwayo esingakhatyelwa zipalini.
Kwimeko kaChrysler, ii-injini zokuqala zokusebenzisa i-Hemi layout yayiziinjini ezimbini ezilungiselelwe ukusetyenziswa emkhosini kwiitanki kunye neejethi zokulwa.
Ukuphela kwemfazwe kunye nokukhawuleza kwexesha le-jet labulala ezi projekthi zimbini, kodwa iinjineli zeChrysler zabona iingenelo zobu buchwepheshe kwaye zasebenzisa kuluhlu lweenjini zeemoto, ezasetyenziswa kwiminyaka emva kweMfazwe Yehlabathi II. Qala nje ukuthengisa.
Isizukulwana sokuqala se-Hemi V8 saveliswa ukusuka kwi-1951 ukuya ku-1958, emele i-valve yokuqala ye-Chrysler yokuvelisa i-V8.Uluhlu lwaqala ngee-intshi ezingama-331 cubic (5.4 ilitha) yeenjini ze-"FirePower" kunye ne-"FireDome" kwaye ekugqibeleni zaphuhliswa kwi-392 Hemi (6.4 ilitha). ).
Kodwa kungcono ukuza.Ngo-1964, isizukulwana sesibini sikaHemi sabonakala kuMntla Melika.I-426 cubic intshi (i-7.0 ilitha) i-Hemi yayiphuhliswe okokuqala kwi-racing ye-NASCAR. Yayibizwa ngokuba yi-injini yeendlovu ngabanye ngenxa yobukhulu bayo bomzimba, kodwa ukususela ngoko iye yalawula kwihlabathi lomdyarho wokutsalwa.
Ekugqibeleni yavalwa yi-NASCAR ngenxa yokukhawuleza kakhulu, i-426 i-Hemi ifumene indawo yayo yokunika amandla ezinye zeemoto ze-Chrysler ezinomfanekiso wemisipha, kuquka i-Plymouth Barracuda (ekwaziwa ngokuba yi-Hemi Cuda exhotyiswe ngale injini) Umgijimi weNdlela kunye ne-GT-X kunye ne-Dodge. , Umceli-mngeni kunye neNyosi enkulu kuquka iTshaja.
Ezinye iishuneli zikwazile ukwandisa i-426 ukuya ku-572 Hemi, kwaye ezi ngoku ziyafumaneka njengeenjini zekhreyithi zokuthengisa emva.
Kule meko, abantu baya kuphinda bacinge nge-Chrysler's 440 cubic inch V8, kodwa i-440 ayiyona i-Hemi design, kodwa isuka kwi-Chrysler's "Magnum" okanye "Wedge" V8 series. (Ungathenga i-440 Hemi ngoku, kodwa umzekelo we-aftermarket ye-Hemi crate injini esekwe kwisizukulwana sesithathu i-V8 Hemi.)
Ukuthetha oku, uthotho lwesithathu lwe-V8 lwe-Chrysler lokusebenzisa ileyibhile ye-Hemi yabonakala ngo-2003 ngohlobo lweelitha ezi-5.7, kwaye emva koko yaphuhliswa kwi-6.1 okanye kwi-6.4 Hemi displacement.
Abaqhubi abaninzi base-Australia baya kuzazi ngakumbi ezi njini kuba banika amandla inguqulelo ye-V8 yohlobo lwe-Chrysler 300C eyasungulwa apha ngo-2005.
Kwimeko yayo yokugqibela, i-Hemi V8 yamva inokusebenzisa i-6.2-litre ye-supercharged form, eyenza ngaphezu kwe-700 horsepower (522 kilowatts) yamandla, kwaye ibonelela ngeetshaja ze-Dodge kunye neemodeli ze-Challenger Hellcat kwimarike yase-US.
Ikwathengiswa kwi-Hemi Jeep Grand Cherokee yase-Australia kunye ne-Hellcat-powered Grand Cherokee Trackhawk.
Injini yeJeep Hemi isuswe ngokuthe ngqo kwikhathalogu yeengxenye zeChrysler ngenxa yokuba ezi nkampani zimbini zingabanini ngokudibeneyo.
Kutshanje, i-Australia ibone ukunyuka kwezixhobo ze-RAM kuMntla Merika, ngakumbi i-RAM 1500 Hemi injini phantsi kwe-hood yayo ebanzi.
Kodwa kukho enye inguqulelo yeChrysler Hemi, apho abanikazi beemoto zase-Australia beminyaka ethile baya kuqhelana nayo.
Kwangeminyaka yoo-1960, iNkampani yaseMelika iDodge yayikhangela injini entsha yokubuyisela injini yelori endala enezisilinda ezintandathu eyayibonelela ngenkonzo elungileyo kuyo. iprojekthi.
Kulapho iChrysler Australia (njengenxalenye yosapho lweChrysler yehlabathi) yangenelela kwaye yathatha iprojekthi, igqibezela ukuyilwa kobuchule obumangalisayo be-215 Hemi, Hemi 245 kunye ne-265 Hemi inline yoyilo lwenjini yesilinda emithandathu, ebonelele ngamandla kunye namandla izizukulwana ezininzi zeemoto zeValiant. kwiminyaka yoo-1970 ukuya kuma-80s.
Ubungakanani benjini ye-Aussie Hemi ukusuka kwi-3.5 ilitha (215 cubic intshi) ukuya kwi-4.0 ilitha (245) kunye ne-4.3 ilitha (265) .Xa ifakwe kwiilori ezikhanyayo kunye ne-utes ephethe i-logo ye-Dodge, ikwabizwa ngokuba yi-Dodge Hemi.
Nangona ingeyiyo i-V8, ezi njini zinakho konke ukusebenza kunye ne-torque eninzi yokufuduka encinci ye-V8.Inguqulelo yokugqibela ye-265 cubic intshi (4.3 ilitha) uguqulelo luxhotyiswe ngee-carburetors ezintathu ze-Weber kwaye lwaphumelela indawo yesithathu e-Bathurst (unyaka). UPeter Brock waqala waphumelela kwiNtaba yePanorama) ngo-1972.
Kubizwa ngokuba yi "six-pack" kule fomu, kwaye yenye yezona zinto zibalaseleyo (kunye nezona ziqokelelweyo) iimoto zemisipha kwimbali yeli lizwe.
Eyaziwayo ngenxa yokuqina kwayo kunye nokuqina kwayo, ingxaki enkulu yokuthembeka kwe-Hemi 6 e-Australia yindawo embi ye-camshaft, evame "ukuhamba" ngobude be-injini.Xa oku kwenzeka, ixesha lokutshisa lingaphoswa ngaphandle.
Kwakhona kubalulekile ukukhankanya ukuba i-Aussie Hemi 6 ayikho ngokwenene i-Hemi.
Ileyibhile yeHemi imalunga nentengiso kunezobunjineli, kodwa akuthandabuzeki ukuba nangoku, iimqinisekiso zokusebenza kwe-injini ziyafana.
Ukuthenga i-Hemi ngoku ukuqhuba kwakhona imoto okanye ukugqiba iprojekthi kuya kuxhomekeka kakhulu kwi-injini oyilandelayo.
Isizukulwana sokuqala saseMelika iHemi V8 siya sinqongophala ngakumbi, kwaye unokuhlawula ngokulula amawaka eedola kwiinjini ezifuna ukulungiswa ngokupheleleyo.
Kuyafana nakwisizukulwana sesibini esidumileyo uHemi 426. Kuya kuba nzima ukuyifumana, kwaye emva koko ufuna iidola ezininzi ukuyisusa kumniniyo.
Isizukulwana sesithathu i-Hemi kulula ukuyifumana, nokuba yintsimi ye-wreckage eyenziwe njengesixhobo esisetyenzisiweyo okanye i-injini yekreyithi phantsi kweemeko ezintsha kraca.
Iyunithi yokusebenza iqala injini yekhreyithi ngexabiso elimalunga nama-7,000 eedola. Ixabiso liqala kumawaka ambalwa eedola ukuya kwi-injini yekhreyithi ye-Hellcat kwi-20,000 yeedola.
Kwi-Hemi 6 e-Australia, iimbaleki zangaphambili zixabisa amakhulu ambalwa eedola, kodwa kuxhomekeke apho uthenga khona kunye neenkcukacha zokugqibela ze-injini, ixabiso lomatshini ohlaziyiweyo liya kuba phezulu ukuya kumawaka eedola.
Nokuba yeyiphi na indlela, uya kuthenga umatshini osele usetyenzisiwe okanye ohlaziyiweyo, ke nceda ujonge intengiso ye-injini ye-Hemi ehlelwe kuqala.
