I-semi-motor: Iyini i-semi-motor?I-hemisphere motor guide yakho

Kukhona isiqubulo sokukhangisa esidumile eNyakatho Melika: "Yebo, ine-Hemi".Futhi lawa magama amahlanu anele ukwenza abalandeli bezimoto zokusebenza bacace lapho uthi nhla. Eqinisweni, lokhu akuwona umbuzo olula ukuwuphendula, ngoba empeleni uchungechunge lwezinjini ezine zomndeni wakwaChrysler zonke ziphethe ilebula yokumaketha ye-Hemi.Omunye wabo umndeni wezitshalo zamandla ezihlukile e-Australia. Ngesikhathi esifanayo, iyini injini enguhhafu (yezinhlamvu ezincane "h")?Konke kubilisa ngendlela yegumbi elivuthayo; isikhala enjinini lapho kushisa khona umoya nophethiloli ukuze kukhiqizwe i-torque, okungamandla ajikisa i-crankshaft futhi ekugcineni amasondo emoto. Usho ukuthini u-Hemi?Eqinisweni, ukwakheka kwaleli gumbi elivuthayo kufana nebhola lethenisi elinguhhafu, noma cishe i-hemispherical, ngakho-ke li-hemispherical.Lokhu kubeka i-spark plug cishe phakathi nendawo yegumbi lomlilo ukuze kuzuzwe ukusakazeka kwelangabi elihle futhi kuvumela ukusetshenziswa kwama-valve amakhulu okudonsa nawokukhipha (ama-valve amakhulu asho umoya owengeziwe nophethiloli ophumayo nangaphakathi). Idizayini yokugeleza okuphambanayo lapho kungena khona umoya nophethiloli kusukela kolunye uhlangothi lwegumbi elivuthayo futhi kuphume kolunye uhlangothi nakho kusiza ukuthuthukisa ukusebenza kahle konke. I-Chrysler akuyena kuphela umkhiqizi wezimoto ongasebenzisa ikamelo elivuthayo eline-hemispherical, kodwa ngenxa yomlingo wokumaketha, isiphenduke uhlobo oluhlobene kakhulu nesakhiwo. Kusukela ngo-1907, abakwaFiat babona amandla e-semi-design futhi bayiletha ethrekhi ngemoto yabo ye-Grand Prix. Kuyathakazelisa ukuthi ukufika kwamakhanda angama-valve amaningi kwehlisa ukukhiqizwa kwezinjini ezinemiklamo ye-hemispherical ngoba ifaneleka kakhulu kuma-valve amabili amakhulu kunama-valve amane amancane. Kodwa ngokuhamba kweminyaka, abakhiqizi abaningi basebenzise i-semi-design, ngisho noma bengakubizanga kanjalo ngoba besaba ukunika u-Chrysler i-free kick. Esimeni sika-Chrysler, izinjini zokuqala ukusebenzisa isakhiwo se-Hemi kwakuyipheya yezinjini eziklanyelwe ukusetshenziswa kwezempi emathangeni nasezindizeni zokulwa. Ukuphela kwempi nokusheshisa kwesikhathi se-jet kwabulala lezi zinhlelo ezimbili, kodwa onjiniyela bakwaChrysler babona izinzuzo zalobu buchwepheshe futhi babusebenzisa ochungechungeni lwezinjini zezimoto, ezasetshenziswa eminyakeni yangemva kweMpi Yezwe II. Vele uqale ukuthengisa. Isizukulwane sokuqala se-Hemi V8 sakhiqizwa kusukela ngo-1951 kuya ku-1958, emele ukukhiqizwa kwe-valve ephezulu ye-Chrysler yokuqala engu-V8. Ukuhlelwa kwaqala ngama-intshi angu-331 cubic inches (5.4 litres) wezinjini ze-"FirePower" kanye ne-"FireDome" futhi ekugcineni zathuthukiswa zaba ngu-392 Hemi (6.4 amalitha ). Kodwa kungcono ukuza.Ngo-1964, isizukulwane sesibili sika-Hemi savela eNyakatho Melika.I-Hemi engu-426 cubic inches (7.0 litres) yeHemi yaqale yenzelwe umjaho we-NASCAR. Abanye bebeyibiza ngenjini yezindlovu ngenxa yobukhulu bayo bomzimba, kodwa selokhu yabusa umhlaba wonke wemijaho yokudonsa. Ekugcineni ivinjelwe yi-NASCAR ngenxa yokushesha kakhulu, i-426 Hemi yathola indawo yayo yokunika amandla ezinye zezimoto zemisipha ezigqama kakhulu zakwaChrysler, okuhlanganisa ne-Plymouth Barracuda (ebuye yaziwe nge-Hemi Cuda ehlome ngale njini) Road Runner kanye ne-GT-X kanye ne-Dodge. , Challenger kanye Super Bee kuhlanganise Ishaja. Amanye amashuna akwazile ukunweba i-426 kuya ku-572 Hemi, futhi lezi seziyatholakala njengezinjini zamakhreyithi ze-aftermarket. Kulokhu, abantu bazophinde bacabange nge-Chrysler's 440 cubic inch V8, kodwa i-440 empeleni ayiwona umklamo we-Hemi, kodwa kusukela kuchungechunge lwe-Chrysler "Magnum" noma "Wedge" V8. (Ungathenga i-440 Hemi manje, kodwa isibonelo senjini ye-aftermarket ye-Hemi crate esekelwe ku-V8 Hemi yesizukulwane sesithathu.) Ekhuluma ngalokhu, uchungechunge lwesithathu lwe-V8 lwe-Chrysler ukusebenzisa ilebula ye-Hemi lwavela ngo-2003 luyimalitha angu-5.7, lwabuye lwathuthukiswa lwaba ngu-6.1 noma ngisho no-6.4 Hemi. ukufuduka. Abashayeli abaningi base-Australia bazozazi kangcono lezi zinjini ngoba banika amandla inguqulo ye-V8 yohlobo lwe-Chrysler 300C eyethulwe lapha ngo-2005. Ngendlela yayo yokugcina, i-Hemi V8 yakamuva ingasebenzisa ifomu elishajwayo elingu-6.2-litre, elikhiqiza amandla angaphezu kuka-700 amahhashi. (522 kilowatts) amandla, futhi inikeza amashaja e-Dodge namamodeli we-Challenger Hellcat emakethe yase-US. Iphinde ithengiswe ku-Hemi Jeep Grand Cherokee yase-Australia kanye ne-Grand Cherokee Trackhawk enamandla kakhulu e-Hellcat. Injini yeJeep Hemi ikhishwa ngokuqondile kukhathalogi yezingxenye ze-Chrysler ngoba lezi zinkampani zombili ziphethwe ngokuhlanganyela. Muva nje, i-Australia iphinde yabona ukwanda kwezinsiza ze-RAM eNyakatho Melika, ikakhulukazi injini ye-RAM 1500 Hemi ngaphansi kwe-hood yayo ebanzi. Kodwa kukhona enye inguqulo ye-Chrysler Hemi, abanikazi bezimoto base-Australia beminyaka ethile abazoyijwayela. Kudala ngeminyaka yawo-1960, i-American Dodge Company yayifuna injini entsha ezothatha indawo yenjini yeloli endala enamasilinda ayisithupha eyayinikeza isevisi enhle. iphrojekthi. Kulapho uChrysler Australia (njengengxenye yomndeni womhlaba wonke wakwaChrysler) angenela khona futhi wathatha iphrojekthi, ephothula ukwakhiwa komklamo omuhle kakhulu wenjini engu-215 Hemi, Hemi 245 kanye no-265 Hemi emgqeni wamasilinda ayisithupha, onikeze amandla namandla izizukulwane eziningana izimoto Valiant. kusukela ngawo-1970 kuya kuma-80s. Ubukhulu benjini ye-Aussie Hemi busukela ku-3.5 litres (215 cubic inches) kuya ku-4.0 litres (245) kanye no-4.3 litres (265).Uma efakwe emalolini amancane nasezintweni ezinophawu lwe-Dodge, abizwa nangokuthi i-Dodge Hemi. Nakuba kungeyona i-V8, lezi zinjini zinakho konke ukusebenza kanye ne-torque eningi ye-V8 encane yokufuduka. Inguqulo yokugcina yenguqulo engu-265 cubic inch (4.3 litre) yayifakwe ama-carburetor amathathu e-Weber futhi yawina indawo yesithathu e-Bathurst (unyaka U-Peter Brock waqala ukunqoba eNtabeni ye-Panorama) ngo-1972. Ibizwa ngokuthi "i-six-pack" kuleli fomu, futhi ingenye yezimoto ezihamba phambili (futhi eziqoqwe kakhulu) zemisipha emlandweni waleli zwe. Eyaziwa ngokuqina nokuqina kwayo, inkinga enkulu yokuthembeka kwe-Hemi 6 e-Australia indawo embi ye-camshaft, evame "ukuhamba" ngobude benjini.Uma lokhu kwenzeka, isikhathi sokuvutha singaphonswa ngaphandle. Kuyafaneleka futhi ukusho ukuthi i-Aussie Hemi 6 empeleni ayiyona i-Hemi nhlobo.Ikhanda le-cylinder alisebenzisi ukuhlelwa kwe-cross-flow, futhi igumbi elivuthayo alinawo umumo we-hemispherical "weqiniso". Ilebula ye-Hemi imayelana nokumaketha kunobunjiniyela, kodwa akungabazeki ukuthi namanje, iziqinisekiso zokusebenza kwenjini ziyefana. Ukuthenga i-Hemi manje ukuze ushayele kabusha imoto noma uqedele iphrojekthi kuzoncika kakhulu enjinini oyilandelayo. Isizukulwane sokuqala saseMelika iHemi V8 siya ngokuya sintuleka, futhi ungakwazi ukukhokha kalula izinkulungwane zamadola ngezinjini ezidinga ukulungiswa ngokuphelele. Kunjalo nangesizukulwane sesibili esidumile iHemi 426.Kuzoba nzima ukuyithola, bese udinga amadola amaningi ukuze uyisuse kumnikazi wayo. I-Hemi yesizukulwane sesithathu kulula ukuyithola, kungakhathaliseki ukuthi inkundla ye-wreckage eyakhiwe njengento esetshenziswayo noma injini yekhreyithi ngaphansi kwezimo ezintsha sha. Iyunithi yokusebenza iqala injini yekhreyithi ngentengo elinganiselwa ku-7,000 amadola. Intengo iqala ezinkulungwaneni ezimbalwa zamadola ukuya ku-20,000 dollar injini ye-Hellcat crate. Ku-Hemi 6 e-Australia, abagijimi bamasekeni babiza amakhulu ambalwa amadola, kodwa kuye ngokuthi uthenga kuphi kanye nemininingwane yokugcina yenjini, intengo yomshini ovuselelwe izoba phezulu njengezinkulungwane zamaRandi. Kunoma ikuphi, uzobe uthenga umshini osetshenzisiwe noma ovuselelwe, ngakho-ke sicela uhlole izikhangiso ezihlukanisiwe zenjini ye-Hemi kuqala.
