I-HEMI, i.e. ama-hemispherical motors avela e-USA - kufanelekile ukuhlola?

Injini enamandla ye-HEMI yaseMelika - yini okufanele ukwazi ngayo?

I-Powerful Muscle Cars ayikwazanga ukunikwa amandla amayunithi amancane ukubala emijahweni yamathrekhi. Ngakho-ke, ngaphansi kwe-hood yale klasi yaseMelika (yanamuhla), kwakudingeka njalo ukukhweza izinjini ezinkulu. Amandla ngelitha kwakunzima ukutholakala ngaleyo minyaka kunamanje, kodwa lokho kwakungeyona inkinga ngenxa yokuntuleka kwemingcele emazingeni okukhishwa kwegesi nokusetshenziswa kukaphethiloli. Ngisho nangaphambi kweMpi Yezwe Yokuqala, kwakungelula ukukhipha amandla amaningana amahhashi enjinini, ngakho kwatholakala izixazululo zokuyilungisa. Ngakho-ke, kwasungulwa izinjini ezinamakamelo omlilo we-hemispherical. Ingabe uyakubona ukukhanya ekupheleni komhubhe manje? Injini ye-HEMI ivela emkhathizwe.

Injini ye-HEMI - idizayini yeyunithi yomlilo

Ukwakhiwa kwamakamelo omlilo ayindilinga kube nomthelela ekwenyukeni okukhulu kokusebenza kahle kwamayunithi avuthayo angaphakathi kangangokuthi abakhiqizi abaningi bomhlaba baqala ukusebenzisa izixazululo ezinjalo ezimotweni zabo. I-V8 HEMI ibingahlali iphambili kwaChrysler, kodwa bekunokuningi kule miklamo kunamandla. Waba yini umphumela wokwakha igumbi elivuthayo ngale ndlela?

Injini ye-HEMI - isimiso sokusebenza

Ukunciphisa ukuma kwesilinda (indilinga) kuholele ekusakazekeni okungcono kwelangabi lapho kubasa ingxube yamafutha omoya. Ngenxa yalokhu, ukusebenza kahle kwanda, njengoba amandla akhiqizwa ngesikhathi sokushisa awazange asakaze ezinhlangothini zesilinda, njengasemiklameni esetshenziswe ngaphambili. I-HEMI V8 iphinde ibe nama-valve amakhulu okuthatha nawokukhipha ukuze kuthuthukiswe ukugeleza kwegesi. Nakuba kulokhu, akuyona yonke into esebenze njengoba kufanele, ngenxa yomzuzu wokungavalwa kanye nokuvulwa kanyekanye kwe-valve yesibili, okubizwa ngokuthi i-valve overlap. Lokhu kudalwe yisidingo esikhulu salolu phiko sikaphethiloli hhayi izinga eliphezulu lezemvelo.

I-HEMI - injini enezici eziningi

Sekudlule iminyaka eminingi kusukela ukwakhiwa kwamayunithi e-HEMI ngeminyaka yama-60s kanye nama-70s kwazuza izinhliziyo zabalandeli bamayunithi anamandla. Manje, ngokuyisisekelo, le miklamo ihluke ngokuphelele, nakuba igama elithi "HEMI" ligcinelwe uChrysler. Igumbi elivuthayo alisafani ne-hemispherical, njengasemiklamo yasekuqaleni, kodwa amandla namandla ahlala.

Ithuthuke kanjani injini ye-HEMI?

Ngo-2003 (emva kokuqaliswa kabusha kokwakhiwa) ukwazile kanjani ukuhlangabezana namazinga amanje wokukhithika? Okokuqala, ukwakheka kwegumbi lomlilo kwashintshwa kwaba yindilinga kancane, okwathinta kakhulu i-engeli phakathi kwama-valve, kwafakwa ama-spark plugs amabili isilinda (izakhiwo ezingcono zokusabalalisa amandla ngemva kokushiswa kwengxube), kodwa futhi ne-HEMI. Uhlelo lwe-MDS lwethulwa. Konke kumayelana nokugudluka okuguquguqukayo, noma kunalokho, ukucisha uhhafu wamasilinda lapho injini ingasebenzi ngemithwalo ephansi.

Injini ye-HEMI - imibono nokusetshenziswa kukaphethiloli

Kunzima ukulindela ukuthi injini ye-HEMI, enguqulweni encane kunazo zonke ine-5700 cm3 ne-345 hp, izoba ukonga. Injini engu-5.7 HEMI enguqulweni engu-345 hp. idla isilinganiso samalitha angu-19 kaphethiloli noma amalitha angama-22 egesi, kodwa lena akuyona yodwa inguqulo yeyunithi ye-V8. Leyo enevolumu engu-6100 cm3, ngokomkhiqizi wayo, kufanele idle isilinganiso esingaphezudlwana nje kwamalitha ayi-18 ngebanga lika-100 km. Kodwa-ke, empeleni, lawa manani adlula amalitha angama-22.

Hlobo luni lokushiswa izinketho ezahlukene ze-HEMI?

I-Hellcat engu-6.2 V8 nayo inhle ekushiseni uphethiloli ethangini. Umkhiqizi ubiza amalitha angu-11 ngebanga lika-100 km emgwaqweni, futhi ungacabanga ukuthi isilo esingaphezu kuka-700 km kufanele sishise uphethiloli waso uma sishayela ngesivinini (ngaphezu kwamalitha angu-20 ekusebenzeni). Bese kuba nenjini ye-HEMI 6.4 V8, edinga amalitha angu-18/100 km (ngokushayela okuphusile), kanti igesi idla amalitha angu-22/100 km. Kusobala ukuthi nge-V8 enamandla akunakwenzeka ukufeza amandla omlilo, njengasedolobheni elingu-1.2 turbo.

5.7 Injini ye-HEMI - amaphutha kanye nokungasebenzi kahle

Yiqiniso, lo mklamo awuphelele futhi unezinkinga zawo. Uma kubhekwa izinkinga zobuchwepheshe, amakhophi akhiqizwa ngaphambi kuka-2006 ayenochungechunge lwezikhathi olunephutha. Ukugqashuka kwayo kungaholela ekushayisaneni kwamapiston namavalvu, okudale umonakalo omkhulu enjinini. Yibuphi ububi bale njini? Okokuqala nje:

• nagarobrazovanie;
• imininingwane ebizayo;
• izindleko eziphezulu zamafutha.

Umkhiqizi futhi uncoma ukuthi angeqi isikhathi sokushintsha uwoyela ngamakhilomitha ayi-10. Imbangela? Isikali sokukhokha. Ngaphezu kwalokho, izingxenye ngokwazo azihlali zishibhile uma uzithenga ezweni lakithi. Yiqiniso, zingangeniswa zivela e-US, kodwa kuthatha isikhathi.

Yini okufanele ukwazi ngamafutha e-HEMI?

Enye inkinga uwoyela injini SAE 5W20 yakhelwe la mayunithi. Kunconywa kakhulu kulawo mamodeli anesistimu yokuvala i-4-cylinder. Yiqiniso, kufanele ukhokhele umkhiqizo onjalo. Umthamo wesistimu yokugcoba ungaphezu kwamalitha angu-6,5, ngakho-ke kunconywa ukuthenga ithangi lamafutha okungenani amalitha angu-7. Izindleko zamafutha anjalo ngesihlungi zingama-euro angama-30.

Ingabe kufanele ngithenge imoto enenjini ye-HEMI V8? Uma ungenandaba nokusetshenziswa kukaphethiloli futhi uthanda izimoto zaseMelika, ungaze ucabange ngakho.
