Inselelo kumele ibe nkulu - igcinwa kanjani injini ye-V12, leyo echaze i-Ferrari isikhathi sonke, ihambisana nezidingo zekhabhoni?
I-patent entsha, efakwe ne-United States Patent and Trademark Office, iveza ukuthi uhlobo lwamahhashi oludlangile luhlose ukugcina i-V12 iminyaka eyishumi ezayo.
Esikubona kumalungelo obunikazi, kubonakala kuwukuvela kwenjini yamanje eyi-V12 (F140), esetshenziswa yiFerrari 812 Superfast noma i-GTC4Lusso, okusho ukuthi ukwembulwa kwayo kungase kube maduzane.
Umehluko ku-V12 ekhona uhlala ikakhulukazi ekhanda lenjini, lapho ungabona khona ukungezwa kwegumbi elincane langaphambi komlilo elinepulaki layo le-spark, ngokushesha ngaphezu kwegumbi elikhulu lomlilo.

Ngamanye amazwi, ukushiswa kwengxube ye-air-fuel nakho kungenzeka kuleli gumbi langaphambili, kodwa kusazobonakala ukuthi kungani uFerrari ekhethe isisombululo esinjalo.
Umgomo uwukukhiqiza ukushisa okwengeziwe ngokushesha ngenkathi injini ibanda, okuzobangela ama-catalysts afinyelela izinga lokushisa elilungile lokusebenza kwawo ngokushesha (300º C kuya ku-400º C), ikhulisa ukusebenza kahle kwayo futhi inciphisa umoya okhishwayo ngenkathi injini ingafinyeleli izinga lokushisa elivamile lokusebenza.
Ukwenza lokhu, ekuqaleni okubandayo - akufanele kudidaniswe ne "Cold Starts" yethu - i-pre-chamber isho ingxube yokuqala yamafutha omoya ehlukene nokushisa okuyinhloko, ukuthuthukisa ingxube yangaphambi kokushisa ngokungenisa amagesi afudumele ekamelweni lokushisa. futhi kudala isiyaluyalu.
Ngale ndlela, ukuthungela okuyinhloko kungabambezeleka, okuholela, ngemuva kokuthungela, ekukhishweni okusheshayo kwamagesi (okushisa) ekamelweni elivuthayo, okunomthelela esikhathini esifushane sokuthi ama-catalysts afinyelele izinga lokushisa elilungile lokusebenza - i ngokushesha uhlelo luyashisa, ngcono uhlelo lokwelapha igesi ephumayo luzosebenza, ngakho-ke luzongcolisa kancane.
Ukushiswa okukhiqizwe i-pre-chamber nakho kudala isiyaluyalu, okufana nalokho okukhiqizwa injini egijima ngama-revs aphezulu, okugcina ukuvutha kuzinzile (ukugwema ukuqhunyiswa kwangaphambili).
Izisi ezikhishwa izinjini eziphezulu ngenkathi zingafudumali ziyaqhubeka nokuba yinkinga okunzima ukuyixazulula, ngenxa yesikhathi esithatha ama-catalytic converters ukushisa. Kunzima kakhulu uma sicabangela injini enkulu njengeV12 yeFerrari.
Isixazululo se-Ferrari asihlosile “ukusungula kabusha isondo”, kodwa nokho kuwukuziphendukela kwemvelo okubalulekile ukuze kuqinisekiswe ukuphila isikhathi eside kwenjini ye-V12 kanye nokuhambisana kwayo nezidingo ezikhulayo ezifunwa kakhulu mayelana nokukhipha umoya.
