Semi-motor: Chii chinonzi semi-motor? Your hemisphere motor guide

Kune yakakurumbira kushambadzira sirogani muNorth America: "Hongu, ine Hemi" .Uye aya mazwi mashanu akakwana kuita kuti mafani emotokari ekuita akajeka pakatarisa. Kutaura zvazviri, iyi haisi mubvunzo uri nyore kupindura, nokuti chaizvoizvo injini ina dzakatevedzana dzemhuri yeChrysler dzose dzinotakura zita rekutengesa reHemi.Mumwe wavo imhuri yemiti yemagetsi yakasiyana neAustralia. Panguva imwe chete, chii chinonzi (lowercase "h") hafu injini?Zvose zvinowira pasi kune chimiro chekamuri inopisa; nzvimbo iri muinjini umo mhepo nemafuta zvinotsva kugadzira torque, inova simba rinotenderedza crankshaft uye pakupedzisira mavhiri emotokari. Hemi anorevei? Chaizvoizvo, chimiro chekamuri inopfuta iyi yakafanana nebhora retenisi hafu, kana kuti rinenge rehemispherical, saka rine hemispherical. kushandiswa kwemavharuvhu makuru ekupinza uye kupera (mavharuvhu makuru anoreva mhepo yakawanda uye mafuta mukati nekubuda). Muchinjikwa-kuyerera dhizaini uko mweya nemafuta zvinopinda kubva kune rimwe divi rekamuri yekupisa uye kubuda kubva kune rimwe divi rinobatsirawo kuvandudza kushanda kwese. Chrysler haisiriyo yega mugadziri wemotokari yekushandisa hemispherical combustion chamber, asi nekuda kwemashiripiti ekushambadzira, yakave iyo mhando inonyanya kuenderana neiyo marongerwo. Kare muna 1907, Fiat yakaziva kugona kwehafu-dhizaini uye yakaunza iyo panjanji nemota yayo yeGrand Prix. Sezvineiwo, kuuya kwema-multi-valve cylinder heads kwakaderedza kugadzirwa kweinjini dzine hemispherical designs nekuti yakanyatsokodzera mavharuvhu maviri makuru kupfuura mavharuvhu mana madiki. Asi nekufamba kwemakore, vagadziri vazhinji vakashandisa iyo semi-dhizaini, kunyangwe ivo vasina kuidaidza nenzira iyo nekuti vaitya kupa Chrysler mahara. Munyaya yaChrysler, injini dzekutanga kushandisa Hemi marongerwo aive maviri einjini dzakagadzirirwa kushandiswa kwemauto mumatangi uye ndege dzehondo. Kuguma kwehondo uye kukurumidza kwezera rejeti kwakauraya mapurogiramu maviri aya, asi mainjiniya eChrysler akaona kubatsirwa kweiyi tekinoroji uye akaishandisa mumutsara weinjini dzemotokari, dzakashandiswa mumakore mushure meHondo Yenyika II. Ingotanga kutengesa. Chizvarwa chekutanga cheHemi V8 chakagadzirwa kubva muna 1951 kusvika muna 1958, chinomiririra Chrysler yekutanga kugadzirwa kwevhavhavhavhavha V8. Mutsara wakatanga ne 331 cubic inches (5.4 litita) ye "FirePower" uye "FireDome" injini uye pakupedzisira yakagadziridzwa kusvika 392 Hemi (6.4 malita. ) Asi zviri nani kuuya.Muna 1964, chizvarwa chechipiri cheHemi chakaonekwa kuNorth America.Iyo 426 cubic inches (7.0 litres) Hemi yakatanga kugadzirirwa NASCAR racing. Yakanzi injini yenzou nevamwe nekuda kwehukuru hwayo hwemuviri, asi kubvira ipapo yave kutonga nyika yekudhonza. Yakazorambidzwa neNASCAR nekuda kwekumhanya zvakanyanya, 426 Hemi yakawana nzvimbo yekusimbisa dzimwe mota dzeChrysler dzakanyanya mhasuru, kusanganisira iyo Plymouth Barracuda (inozivikanwawo seHemi Cuda yakashongedzerwa neinjini iyi) Road Runner neGT-X pamwe neDodge. , Challenger uye Super Bee kusanganisira Charger. Mamwe matuner akakwanisa kuwedzera 426 kusvika 572 Hemi, uye aya ave kuwanikwa semakrete enjini eiyo aftermarket. Muchiitiko ichi, vanhu vachafungawo nezveChrysler's 440 cubic inch V8, asi 440 haisi iyo Hemi yakagadzirwa, asi kubva kuChrysler's "Magnum" kana "Wedge" V8 series. (Unogona kutenga 440 Hemi ikozvino, asi ndiyo muenzaniso weiyo aftermarket Hemi crate injini yakavakirwa pachizvarwa chechitatu V8 Hemi.) Achitaura nezveizvi, Chrysler yechitatu V8 akatevedzana kushandisa Hemi label akaonekwa muna 2003 muchimiro 5.7 litres, uye ipapo akagadziridzwa 6.1 kana kunyange 6.4 Hemi. kutama. Vatyairi vakawanda vekuAustralia vachange vachinyanya kujairana nemainjini aya nekuti vanopa simba V8 vhezheni yeChrysler 300C yakatangwa pano muna 2005. Muchimiro chayo chekupedzisira, Hemi V8 yakazotevera inogona kushandisa 6.2-litre supercharged fomu, iyo inobereka anopfuura mazana manomwe emabhiza. (522 kilowatts) yesimba, uye inopa maDodge majaja uye Challenger Hellcat modhi mumusika weUS. Inotengeswa zvakare muAustralia Hemi Jeep Grand Cherokee uye supercharged Hellcat-powered Grand Cherokee Trackhawk. Iyo Jeep Hemi injini inobviswa zvakananga kubva kuChrysler zvikamu catalog nekuti makambani maviri aya ndeayo akabatana. Munguva pfupi yapfuura, Australia yakaonawo kusimuka kwezvishandiso zveRAM muNorth America, kunyanya iyo RAM 1500 Hemi injini pasi pehodhi yayo yakafara. Asi pane imwe shanduro yeChrysler Hemi, iyo vatenzi vemotokari yeAustralia yezera rakati vachaziva. Kare kuma1960, American Dodge Company yaitsvaga injini itsva yekutsiva yekare oblique six-cylinder rori injini yaipa basa rakanaka kwairi. project. Apa ndipo pakapinda Chrysler Australia (sechikamu chemhuri yepasi rose yeChrysler) ndokutora chirongwa ichi, vachipedzisa kusikwa kweiyo inoshamisa 215 Hemi, Hemi 245 uye 265 Hemi inline six-cylinder injini dhizaini, iyo yakapa simba uye simba kune. zvizvarwa zvakawanda zveValiant mota. yakaitika kuma1970 kusvika kuma80s. Ukuru hweinjini yeAussie Hemi kubva ku3.5 litita (215 cubic inches) kusvika ku4.0 litita (245) uye 4.3 litita (265) .Kana yakaiswa pamarori akareruka uye utes ane Dodge logo, anonziwo Dodge Hemi. Kunyange zvazvo isiri V8, injini idzi dzine maitiro ose uye torque yakawanda yediki yekutamisa V8. The yekupedzisira shanduro ye 265 cubic inch (4.3 litre) shanduro yakanga yakashongedzerwa netatu Weber carburetors uye yakakunda nzvimbo yechitatu muBathurst (gore. Peter Brock akatanga kuhwina paPanorama Mountain) muna 1972. Inonzi "matanhatu-pack" mune iyi fomu, uye ndeimwe yeakanakisa (uye inounganidzwa) mota dzetsandanyama munhoroondo yenyika ino. Inozivikanwa nekuoma kwayo uye kusimba, dambudziko guru rekuvimbika reHemi 6 muAustralia inzvimbo yakashata yecamshaft, iyo inowanzo "kufamba" pamwe chete nehurefu hwejini.Kana izvi zvikaitika, nguva yekudzima inogona kukandwa kunze. Izvo zvakakoshawo kutaura kuti Aussie Hemi 6 haisi chaiyo Hemi zvachose.Musoro we cylinder haushandisi muchinjikwa-kuyerera, uye kamuri rinopisa harina "yechokwadi" hemispherical shape. Iyo Hemi label iri pamusoro pekushambadzira kupfuura engineering, asi hapana kupokana kuti kunyangwe ikozvino, injini yekushanda zvitupa zvakafanana. Kutenga Hemi izvozvi kutyaira mota kana kupedzisa purojekiti zvakanyanya zvinoenderana neinjini yaunotevera. Chizvarwa chekutanga cheAmerican Hemi V8 chiri kuramba chichishomeka, uye unogona kubhadhara nyore zviuru zvemadhora kune injini dzinoda kugadziridzwa kwakazara. Zvakafanana ndezvechokwadi chechizvarwa chechipiri cheHemi 426. Zvichava zvakaoma kuwana imwe, uye iwe unoda madhora akawanda kuti uibvise kubva kumuridzi wayo. Chizvarwa chechitatu cheHemi chiri nyore kuwana, ingave munda wewreckage wakagadzirwa sechishandiso chakashandiswa kana injini yekrete pasi pemamiriro matsva. Iyo inoshanda unit inotanga injini yekrete pamutengo wemadhora zviuru zvinomwe. Mutengo unotanga kubva pazviuru zvishoma zvemadhora kuenda kuHellcat crate engine's 20,000 dollars. Kune Hemi 6 muAustralia, vamhanyi vechipiri vanodhura mazana mashoma emadhora, asi zvichienderana nekuti unotenga kupi uye nezvinotsanangurwa zvekupedzisira zveinjini, mutengo wemuchina wakagadziridzwa uchakwira sezviuru zvemadhora. Chero nzira, unenge uchitenga wakashandiswa kana kugadziridzwa muchina, saka ndapota tarisa Hemi injini yekutengesa yakakamurwa ads kutanga.
