IPorsche inkqenkqeza phambili kugqatso lwe "grail engcwele" yetekhnoloji ephezulu kwiinjini zokutsha zangaphakathi: ukufikelela kwinqanaba elinomona loxinzelelo oluguquguqukayo. Yazi umahluko.
Iziphumo zentsebenziswano phakathi kweenjineli zePorsche kunye nenkampani yobunjineli i-Hilite International, i-Porsche ibonakala ngathi ifike kwisisombululo esisebenzayo sokufezekisa ezona hlabathi zimbini kwiinjini eziphezulu.
I-Porsche ifunda ukwenzeka kokusetyenziswa koxinzelelo oluguquguqukayo ukunyusa ukusebenza kakuhle kweenjini ze-turbo kwi-revs ephantsi, ithi ndlela-ntle ngonaphakade kwi-'turbo lag', ngaphandle kwesidingo seenkqubo ezincanyathiselweyo ukuze i-turbine ye-turbocharger isoloko ijikeleza ngesantya esiphezulu.
FUNDA KWAKHONA: Le yibhonasi eya kufunyanwa ngabasebenzi bakwaPorsche
Isizathu sokuba le teknoloji ivuse umdla ongaka, okhokelela ekuhanjisweni kwemithombo yobutyebi, ngoku ifumana i-preponderance enkulu kunye nesidingo sokwandisa ukusebenza kakuhle kweenjini zokutsha zangaphakathi. Phambi kokuba sibabone bewushiya umboniso wemoto ngokupheleleyo, “nentsholongwane yokuncipha” kuyo yonke indawo, esona sisombululo sikhawulezayo nesinexabiso eliphantsi yayikukubhenela kwi-supercharging ngokusebenzisa i-turbocharger. Kodwa ayizizo zonke izinto ezimele ukusebenza kakuhle xa sibandakanya ukusetyenziswa kwe-turbocharger kule nxaki.
Nokuba kungakanani na ukusebenza kakuhle okunokwenzeka kokukhupha kobu matshini, kukho imida yesakhiwo kwaye iisilinda zikwazi ukuzalisa umthamo womoya owongezelelweyo ovela kwi-turbo compressor, umlinganiselo wokucinezelwa kwezi njini kufuneka ube ngaphantsi kakhulu kunoko. kweenjini ngenye indlela, into yokuzidubula, eyintlekele kuyo nayiphi na injini, inokuba yinto engatshintshiyo.
Yintoni umahluko? Uyilo olutsha lokudibanisa intonga
Uphawu lobume be-injini ye-turbo kwi-revs ephantsi luyaziwa kwaye endaweni yokubhenela kwimibhobho yamanzi eyongezelelweyo, ebizwa ngokuba yi-“Anti-Lag Systems” (esebenzisa ngokufutshane “iivalvu ze-bypass” kumbhobho wokuphuma) IPorsche iza noyilo olutsha lokuqhagamshela. iintonga. Ezi ntonga zintsha zokuqhagamshela ziqulathe ii-actuator zehydraulic kwaye zikuvumela ukuba utshintshe indawo yeepistons, ngaloo ndlela ufezekise umlinganiselo onqwenelekayo woxinzelelo oluguquguqukayo.
Ngesi sisombululo, i-Porsche iyakwazi ukwenza ukungakhathali kwe-turbo kwi-revs ephantsi kungabi sabonakala, kuba ngale teknoloji kunokwenzeka ukuba utshintshe indawo yeepiston kwindawo yoxinzelelo oluphezulu, ukwandisa ukusebenza kakuhle kwi-rpm ephantsi. i-injini iphendula njengebhloko ye-atmospheric.
AKUMELE UPHOSEWE: I-Porsche 911 GT3 RS iyasebenza
Le teknoloji iya kuphucula ukusetyenziswa kunye nejika lamandla. Nje ukuba iigesi zombhobho zikwazi ukujikeleza iturbocharger turbine, ipistons zithotywa ukuya kwindawo ephantsi yomlinganiselo woxinzelelo ukuze icompressor yeturbo ihambise umthamo womoya owongezelelweyo kuxinzelelo oluphezulu lweturbo ekwaziyo ukuyenza. , ivelisa amandla angaphezulu, ngaphandle komngcipheko ukuqhushumba kweemoto kunye nokubalwa kwangaphambili kokutshiswa ngokungekho ngqiqweni yi-ECU.
Kuyilo esikubonisa lona, i-Porsche yagqiba ukubonelela ngentonga yokudibanisa kunye ne-valve ye-solenoid ephantsi yoxinzelelo, ethi, ngokuguqula uxinzelelo lweoli phakathi kwe-actuator ye-hydraulic actuators, i-rods yokulawula ihambisa i-bearing phezu kwentonga yokudibanisa ngokuzenzekelayo. Le ntshukumo ehlayo okanye eyonyukayo iyahluka kwipiston kwizikhundla ezibini: ephezulu kumlinganiselo woxinzelelo oluphezulu kunye nelinye elisezantsi kumlinganiselo ophantsi woxinzelelo.
I-Porsche iqinisekisa ukuba iqinisekisa urhwebo kunye nokusebenza komatshini kobu buchwepheshe, iya kukhulula ilungelo elilodwa lomenzi wechiza ukuze isetyenziswe yimarike.
