Kwakungonyaka ka-1997 lapho sazana khona neDodge Viper GTS, umfelandawonye we "monster" waseMelika, owahlomisa injini yeV10 eyaziwayo ngokwemvelo engu-8.0 l, manje ekhiqiza i-50 hp ngaphezu kwe-roadster yasekuqaleni, ehlala endaweni evulekile. "amafutha" 456 hp amandla.
Lesi sifanekiso, kusukela ngonyaka wezi-2000, sino-61,555 km ku-odometer futhi sisesekuqaleni ngokuphelele. Kungenzeka yini ukuthi eminyakeni engu-21 kamuva, i-456 hp eyamenyezelwa ye-blockous 10-cylinder "V" block isekhona yonke?
Ukuphendula lo mbuzo, akukho okungcono kunokuthatha i-Viper GTS uyiyise ebhange lamandla.
Kodwa ngaphezu kokuhlolwa kwebhange lamandla, labo ababhekele isiteshi se-YouTube i-Four Eyes basebenzise ithuba ukuze babone ukuthi akhona yini amathuba okuthuthukisa ukusebenza kwe-V10 enkulu, kusetshenziswa ikhompuyutha kuphela, beshintsha imephu yayo - naphezu kokuthi indala, i-Viper GTS. yakamuva ngokwanele ukuvumela lolu hlobo lokukhohlisa, ngisho nokwakhela phezu kwentuthuko eyenziwe kule ndawo kule minyaka engamashumi amabili edlule.
Isinyathelo sokuqala salo msebenzi kwakuwukubona ukuthi angakanani amandla ayenawo futhi umphumela waba muhle impela: 415 hp (410 hp) ikalwa emasondweni. Lokhu kusho ukuthi, kucatshangelwa ukulahleka kokudluliselwa (ngokuvamile phakathi kuka-10% no-15%), i-8.0 V10 kufanele ishaje i-crankshaft inani lamandla ngokuhambisana nalokho okumenyezelwe njengokusha - akukubi uma kucatshangelwa iminyaka yayo engama-21.
Nokho, lolu hlolo lokuqala luhlonze ngokushesha indawo lapho bekungenzeka khona ukuthuthukisa ukusebenza kwe-V10 futhi uthole amandla engeziwe. Ochungechungeni oluthile lokuguquguquka, kwatholakala ukuthi ingxube ye-air-fuel yayicebile kakhulu (ijova uphethiloli owengeziwe kunalokho okudingekayo), okubangele ikhefu ku-torque curve.
Imephu entsha yeyunithi yokulawula injini, ethuthukise ingxube yamafutha omoya kulezi zinhlelo, ngokushesha yaqinisekisa ukwanda kwamandla angu-8 hp emasondweni.
Isinyathelo esilandelayo kwaba ukuthuthukiswa kokushisa, ukuqhubekela phambili, lapho kwakungenzeka khona ukuthola enye i-hp engu-10, lapho i-hp eyengeziwe engu-10 yengezwe, ifinyelelwe ngokulungiswa okusha kwe-air-fuel ratio.
Sekukonke, ngemva "kwezinguquko" ezinhlanu ekuphathweni kwe-elekthronikhi, kwakungenzeka "ukuqala" enye i-29 hp kusukela enjini enkulu engu-8.0 l V10, eyaqala ukuletha i-444 hp (no-655 Nm), ilinganiswa amasondo, ngokumelene ne-415 hp (kanye ne-610 Nm) yesivivinyo sokuqala, okumelela ukuzuza kwamandla angu-6.8% (kanye ne-torque engu-7.3%.
Ngamanye amazwi, eminyakeni engu-21 kamuva, le Dodge Viper GTS ikhipha amandla netorque engeziwe kunaleyo eyayenza lapho iphuma embonini, futhi konke lokhu ngaphandle kokushintsha ingxenye eyodwa - ukulungisa nje "izingcezu namabhayithi" eziwalawulayo - eziwalawulayo. ikhombisa kahle amandla le njini eyingqophamlando eyi-V10 eyayinawo ngenkathi yethulwa.
Ukuhlolwa komgwaqo okuncane kwenze kwaba nokwenzeka ukufakazela izinzuzo, ukulinganisa isikhathi sokusheshisa kwe-Viper ngegiya lesibili, phakathi kuka-30 mph no-80 mph, okungukuthi, phakathi kuka-48 km/h no-129 km/h—yebo, eyesibili ye-Viper eside. Ngaphambi kokuhlolwa kwebhange lamandla isikhathi sasingu-5.9s, bese sehlela ku-5.5s (minus 0.4s) - umehluko omkhulu...
