Ehlabathini, eyona njongo iphambili kukuphucula uqoqosho lwepetroli ngaphandle kwemibingelelo malunga nayo nayiphi na enye indlela yokusebenza. Kwinyathelo lokuqala, uphononongo lweparamitha yedifuser eneedifusi lubonisa ukuba uphuculo olusebenzayo kwiindawo ezifanelekileyo zokusebenza lunokwenzeka ngexabiso lokunciphisa ububanzi bemephu. Ukuqukumbela kwiziphumo iijiyometri ezintathu eziguquguqukayo ezinobunzima obahluka-hlukeneyo ngokusekwe kwi-vaned diffusers ziyiliwe. Iziphumo ezivela kwindawo yokuvavanya igesi eshushu kunye ne-injini yokuvavanya i-injini ibonisa ukuba zonke iinkqubo ziyakwazi ukunyusa ukusebenza kwe-compressor kwaye ngaloo ndlela ziphucula uqoqosho lwe-fuel kuluhlu oluphambili lokuqhuba ii-injini ezinzima.
Imingeni eyongezelelweyo imelwe yimfuno yokuqina okuphezulu, ukukhutshwa kwengxolo ephantsi kunye nokusebenza kakuhle okwethutyana kwe-injini. Ke ngoko, uyilo lwenkqubo yecompressor luhlala lulungelelanisa phakathi kokusebenza okuphezulu, ububanzi bemephu ebanzi, ubunzima obuphantsi be-impeller kunye nokuqina okuphezulu okukhokelela kwizigaba zecompressor kunye nelahleko enkulu ye-aerodynamic kuluhlu oluphambili lokuqhuba izithuthi ezithatha ixesha elide kwaye ke ngoko ukunciphisa uqoqosho lwamafutha. Ukusombulula le ngxaki isisiseko yoyilo lwecompressor ngokwazisa ijiyometri eguquguqukayo kunokukhokelela ekuncitshisweni kweendleko zizonke zobunini eyona ndawo iphambili yokuthengisa malunga neenjini zomsebenzi onzima. Ngaphandle kweevalvu eziphinda zisetyenziswe kwii-turbocharger zemoto yabahambi, iicompressor ezinejiyometri eguquguqukayo azikhange ziyifumane indlela yazo yokuvelisa uthotho nangona uphando olunzulu lwenziwe kweli candelo.
Iicompressor ezintathu eziguquguqukayo ziye zaphuhliswa ngenjongo yokuphucula uqoqosho lwamafutha eenjini ezinobunzima bomsebenzi ophambili kuluhlu lokuqhuba ngaphandle kokuwohloka ngokubhekiselele kumandla alinganisiweyo, i-torque ephezulu, ukuzinza kunye nokuqina. Kwinqanaba lokuqala, iimfuno ze-injini ngokubhekiselele kwinqanaba le-compressor ziye zafunyanwa kwaye iindawo zokusebenza ezifanelekileyo ze-compressor zichongiwe. Uluhlu oluphambili lokuqhuba iilori ezihamba ixesha elide zihambelana neendawo zokusebenza kwimilinganiselo yoxinzelelo oluphezulu kunye nokuhamba kobunzima obuphantsi. Ilahleko yeAerodynamic ngenxa yee-engile zokuqukuqela okubambekayo kwi-vaneless diffuser idlala indima ephambili kolu luhlu lokusebenza.
