Injini ye-Lexus LFA
Okuqukethwe
ILexus LFA iyimoto yokuqala yakwaToyota enezihlalo ezimbili. Zingu-500 sezizonke izimoto ezikhiqiziwe. Umshini ufakwe iyunithi yamandla ehlangene futhi enamandla. Injini inikeza uhlamvu sporty imoto. Injini yenzelwe uku-oda, okwayivumela ukuba ibe isimangaliso sobunjiniyela.
Incazelo emfushane yemoto
Ngo-2000, i-Lexus yaqala ukwakha imoto yezemidlalo ebizwa ngokuthi i-P280. Zonke izixazululo ezisezingeni eliphezulu zeToyota ezikhathazayo bekumele zibonakale emotweni. I-prototype yokuqala yavela ngoJuni 2003. Ngemva kokuhlolwa okubanzi e-Nurburgring ngoJanuwari 2005, i-Premiere ye-LF-A concept yenzeka e-Detroit Auto Show. Imoto yomqondo wesithathu yethulwa ngoJanuwari 2007. I-Lexus LFA yakhiqizwa ngobuningi kusukela ngo-2010 kuya ku-2012.
I-Lexus ichithe cishe iminyaka eyi-10 ithuthukisa i-LFA. Lapho kuklanywa, kunakwe yonke into. Ngakho-ke, isibonelo, i-spoiler yangemuva ithole ithuba lokushintsha i-angle yayo. Lokhu kukuvumela ukuthi ukhuphule amandla e-axle yangemuva yemoto. Onjiniyela bagxile emininingwaneni emincane kakhulu, ngakho-ke nawo wonke amantongomane akhelwe ukusebenza ngendlela ethembekile futhi abukeke emuhle.
Abaklami abahamba phambili emhlabeni basebenza ngaphakathi kwemoto. Izihlalo zamathambo ezisekelwa eceleni zilungisa ngokuphephile umshayeli nomgibeli. Umshini usebenzisa ubuchwepheshe be-Remote Touch, obungena esikhundleni segundane lekhompyutha. Ngosizo lwayo, kulula ukuphatha zonke izinketho zokunethezeka ku-cabin. Ukuqeda i-Lexus LFA kwenziwa kusetshenziswa i-carbon fibre, isikhumba, insimbi ecwebezelayo ne-Alcantara.
Ukuphepha okusebenzayo nokungenzi lutho kweLexus LFA kusezingeni eliphezulu. Imoto ine-Brembo braking system enama-carbon/ceramic discs. Imoto inama-airbag. Umzimba unokuqina okuphezulu. Kusukela ukuyidala, iToyota ithuthukise umshini okhethekile wokweluka isiyingi se-carbon fiber. Imoto ibonakale ilula, kodwa iqinile ngokwanele ukwehlisa ingozi yokulimala engozini.
Injini ngaphansi kwe-hood Lexus LFA
Ngaphansi kwe-hood ye-Lexus LFA kune-1LR-GUE powertrain. Lena injini engu-10-cylinder eyakhelwe ngokukhethekile lolu hlobo lwemoto. Ochwepheshe abahamba phambili be-Yamaha Motor Company babambe iqhaza ekuthuthukisweni. I-motor ifakwe ngangokunokwenzeka kusukela kubhampa ngaphambili ukuze kuthuthukiswe ukusabalalisa isisindo semoto ku-48/52. Ukuze kuncishiswe indawo ephakathi kwamandla adonsela phansi, isikhungo sikagesi sathola isistimu yokugcoba ye-sump eyomile.
I-Lexus LFA iyimoto esebenza kahle kakhulu emoyeni. Zonke izimbobo kuwo azenziwanga ngobuhle, kodwa ngezinhloso ezingokoqobo. Ngakho-ke, isibonelo, indawo yokucindezela ephansi yakhiwe eduze kwe-gratings lapho ushayela ngesivinini esikhulu. Lokhu kukuvumela ukuthi udonse ukushisa endaweni yenjini, uqhubeke nokupholisa injini elayishiwe. Ama-radiators okupholisa atholakala ngemuva komshini, okuthuthukisa ukusatshalaliswa kwesisindo sawo.
Injini engu-1LR-GUE iyakwazi ukusuka kokungenzi lutho iye kumugqa obomvu ngemizuzwana engu-0.6. I-analog tachometer ngeke ibe nesikhathi sokulandelela ukujikeleza kwe-crankshaft ngenxa ye-inertia yesistimu. Ngakho-ke, isikrini sekristalu esiwuketshezi sakhiwe kudeshibhodi, ebonisa ukudayela okuhlukahlukene nolunye ulwazi. Umshini usebenzisa i-digital discrete tachometer, enquma ngokungaqondile isivinini sangempela se-crankshaft.
Iyunithi yamandla inomkhawulo ophezulu wokuphepha. Isistimu yokugcoba i-sump eyomile ivimbela indlala kawoyela nganoma yisiphi isivinini nasemakhoneni. Ukuhlanganiswa kwenjini kwenzeka ngokuphelele ngesandla nangomuntu oyedwa. Ukumelana nemithwalo ebalulekile ku-1LR-GUE isetshenziswa:
- ama-piston akhiwe;
- izintambo zokuxhuma i-titanium;
- izingalo ze-rocker eziboshwe ngetshe;
- ama-valve e-titanium;
- i-crankshaft eyakhiwe.
Izici zobuchwepheshe zeyunithi yamandla engu-1LR-GUE
Injini engu-1LR-GUE ilula futhi iwumsebenzi onzima. Ivumela iLexus LFA ukuthi ikwazi ukugijima ifinyelele ku-100 km/h ngemizuzwana engu-3.7. Indawo ebomvu yemoto itholakala ku-9000 rpm. Idizayini yenjini evuthayo yangaphakathi ihlinzeka ngama-valve angu-10 ahlukene kanye nenani elihlukahlukene lokungenisa. Okunye ukucaciswa kwenjini kungatholakala kuthebula elingezansi.
| Ipharamitha | Okushoyo |
|---|---|
| Inani lamasilinda | 10 |
| Inani lama-valve | 40 |
| Ivolumu eqondile | I-4805 cm³ |
| Ububanzi besilinda | 88 mm |
| Ukushaya kwesibhamu | 79 mm |
| Amandla | 560 h.p. |
| I-Torque | 480 Nm |
| Isilinganiso sokucindezela | 12 |
| Uphethiloli onconyiwe | I-AI-98 |
| Isisetshenziswa esimenyezelwe | ayifanisiwe |
| insiza ekusebenzeni | 50-300 ayizinkulungwane km |
Inombolo yenjini ingaphambili kwebhulokhi yesilinda. Itholakala eduze nezihlungi zamafutha. Eduze kokumaka kunenkundla ekhombisa ukuthi ongoti beYamaha Motor babambe iqhaza ekuthuthukisweni kophiko lukagesi. Ngaphezu kwalokho, imoto ngayinye kwezingu-500 ezikhiqizwayo inenombolo yayo ye-serial.
Ukwethembeka kanye nobuthakathaka
Injini yakwaLexus LFA ikwazile ukuhlanganisa ezemidlalo, ukunethezeka nokuthembeka. Ukuhlolwa kwamayunithi kagesi kuthathe cishe iminyaka eyi-10. Umklamo wesikhathi eside wenza kube nokwenzeka ukugwema zonke "izifo zezingane" zemoto. I-ICE izwela ukuthobela imigomo yesondlo.
Ukuthembeka kweyunithi yamandla kuthinteka ngokufaka i-refueling uphethiloli. Inombolo yayo ye-octane kufanele okungenani ibe ngu-98. Uma kungenjalo, kuvela i-detonation. Iyakwazi ukucekela phansi iqembu le-cylinder-piston, ikakhulukazi ngaphansi kwemithwalo ephezulu eshisayo neyemishini.
Ukugcinwa kwezimoto
Injini engu-1LR-GUE iyisitimela esinamandla esikhethekile. Ukulungiswa kwayo akukwazi ukwenziwa esiteshini esivamile sesevisi. Usonhlamvukazi awukho embuzweni. Izingxenye ezisele ezinophawu lwe-ICE 1LR-GUE azithengiswa.
Ukuhluka komklamo we-1LR-GUE kunciphisa ukugcinwa kwayo kuze kufike kuqanda. Uma kunesidingo, akunangqondo ukuthola ama-analogue ezingxenye eziyisipele zomdabu. Ngakho-ke, kubalulekile ukwenza ukulungiswa ngesikhathi futhi usebenzise kuphela izinto ezisetshenziswayo eziphezulu. Kulokhu, ukulungiswa ngeke kudingeke maduze, ngoba injini inomkhawulo omkhulu wokuthembeka.
Tuning izinjini Lexus LFA
Ochwepheshe abahamba phambili bakwaToyota, Lexus kanye neYamaha basebenze ngenjini engu-1LR-GUE. Ngakho-ke, injini ibonakale iphelele ngokwesakhiwo. Into engcono kakhulu ongayenza ukuthi ungaphazamisi umsebenzi wakhe. Ngakho-ke, ngokwesibonelo, asikho nesisodwa isitudiyo sokulungisa esizokwazi ukudala i-firmware engcono kunomdabu.
Iyunithi yamandla ye-1LR-GUE iyinjini efisa ngokwemvelo. Kodwa-ke, ngeke kwenzeke ukusebenzisa i-turbine kuyo. Azikho izixazululo ezenziwe ngomumo kanye namakhithi e-turbo ale njini athengiswayo. Ngakho-ke, noma yimiphi imizamo yokwenza isimanjemanje ejulile noma ekha phezulu ingaholela ekulimaleni okukhulu kwenjini yomlilo yangaphakathi, hhayi ekwandeni kwamandla ayo.
