Umceli mngeni kufuneka ube mkhulu - uyigcina njani injini ye-V12, leyo echaze iFerrari ngalo lonke ixesha, ihambelana neemfuno zokukhutshwa?
Ilungelo lomenzi elitsha, elifakwe kwi-United States Patent kunye ne-Ofisi yoRhwebo, ityhila indlela ihashe elixhaphakileyo elizimisele ngayo ukugcina i-V12 kwiminyaka elishumi ezayo.
Into esiyibonayo kumalungelo awodwa omenzi wechiza, kubonakala ngathi yinguquko yenjini ye-V12 yangoku (F140), esetyenziswa yiFerrari 812 Superfast okanye iGTC4Lusso, okuthetha ukuba ukutyhilwa kwayo kungakhawuleza.
Umahluko kwi-V12 ekhoyo uhlala ngokusisiseko kwintloko ye-injini, apho unokubona ukongezwa kwegumbi elincinci lokutshisa elingaphambi kwegumbi kunye ne-spark plug yayo, ngokukhawuleza ngaphezulu kwegumbi eliphambili lokutsha.
Bhalisa kwincwadana yethu
Ngamanye amazwi, ukutshiswa komxube we-fuel emoyeni kunokwenzeka kwakhona kweli gumbi langaphambili, kodwa kuya kuhlala kubonakala ukuba kutheni uFerrari ekhethe isisombululo esinjalo.
Injongo kukuvelisa ubushushu obuninzi ngokukhawuleza ngelixa injini ibanda, okuya kubangela ii-catalysts zifikelela kwelona qondo liphezulu lobushushu lisebenza ngokukhawuleza (300º C ukuya ku-400º C), ukwandisa ukusebenza kakuhle kwayo kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo ngelixa injini ingafikeleli kubushushu obuqhelekileyo bokusebenza.
Ukwenza oku, ekuqaliseni okubandayo - ukuba ungadideki kunye ne "Cold Starts" yethu - i-pre-chamber ithetha umxube wokuqala we-air-fuel eyahlukileyo ukusuka kwindawo yokutshisa, ukuphucula umxube wangaphambili wokutshisa ngokuzisa iigesi ezifudumele kwigumbi lokutshisa. kwaye idala isiphithiphithi ngakumbi.
Ngale ndlela, ukutshisa okuphambili kunokulibaziseka, kubangele, emva kokutshisa, ukugxotha ngokukhawuleza kweegesi (ezishushu) ukusuka kwigumbi lokutsha, okunegalelo kwixesha elifutshane lexesha lokuba i-catalysts ifikelele kwiqondo lokushisa eliphezulu lokusebenza - i ngokukhawuleza inkqubo iyatshisa, ngcono inkqubo yokucoca igesi yokukhupha iya kusebenza, ngoko ke iya kungcolisa kancinci.
Ukutsha okwenziwa ligumbi langaphambili nako kuvelisa isiphithiphithi ngakumbi, esifana naleyo iveliswa yi-injini esebenza kwii-revs eziphezulu, ukugcina ukutsha kuzinzile (ukuphepha ukuqhushumba kwangaphambili).
Ukukhutshwa okuphezulu okwenziwa zii-injini ngelixa kungafudumezi kuyaqhubeka kuyingxaki ekunzima ukuyicombulula, ngenxa yexesha elithatha i-catalytic converters ukutshisa. Kunzima ngakumbi ukuba siqwalasela injini enkulu efana neV12 yeFerrari.
Isisombululo sikaFerrari asizimiselanga “kuphinda siqalise ivili”, kodwa noko kunjalo lutshintsho olubalulekileyo lokuqinisekisa ubomi obude benjini ye-V12 kunye nokuhambelana kwayo neemfuno ezibangwayo ngokwandayo malunga nokukhutshwa kwezinto ezikhutshwayo.
