Iyini i-double scroll turbocharger? [ukuphatha]

Imiklamo yezinhlelo ze-supercharger iyahlukahluka kuye ngezidingo zabaklami. Esinye sezidingo ezingavamile isifiso sokuthola i-torque ephezulu ngesivinini esiphansi kakhulu ngaphandle kokuyeka amanani aphezulu ngesivinini esikhulu, futhi lokhu kusenjini kaphethiloli. Kubonakala sengathi injini kaphethiloli akasoze imbobo eqinile njengoba injini diesel, kodwa kuvela ukuthi kungaba. Konke lokhu kungenxa yesistimu yokuskrola kabili.

Ungasebenzisa izindlela ezahlukahlukene zokugcwalisa, kuhl. i-geometry eguquguqukayo noma izinhlelo ze-twin-turbo ne-bi-turbo, kodwa esimweni ngasinye kunenkinga yokuthi amagesi aphumayo avela kumasilinda angawodwana awangeni ku-rotor ye-turbine kanyekanye nangokulinganayo, kodwa ngendlela eshayayo futhi eguquguqukayo. Ngenxa yalokho, bayagxambukela ekungeneni kwezindlu ze-turbine futhi bangasebenzisi amandla abo aphelele.

Ngakho-ke isixazululo se-turbocharged esine-twin-scroll esihlukanisa i-exhaust eningi ibe amashaneli amabili (ekhonjiswe ngokubomvu), enye yayo esebenza, isibonelo, enjini ye-4-cylinder, amasilinda angaphandle, kanti enye, amasilinda angaphakathi. Lokhu kugwema ukuthikamezeka nokugeleza yonke indlela eya ezindlini eziphehla ugesi. Kukhona futhi iziteshi ezimbili lapha, kodwa kukhona igumbi elilodwa phambi kwe-rotor (ekhonjiswe ngokuluhlaza okwesibhakabhaka). Ngokukhetha ubude obulungile nomthamo wezimbobo zokungenisa, ungasebenzisa izenzakalo zamagagasi ezihlotshaniswa nomjikelezo wokuphehla kwenjini, futhi usebenzise ngokuphumelelayo amandla amagesi akhipha umoya. Ngenxa yalokhu kuhlukaniswa kwezindlu ze-turbine, ukuphazamiseka okungadingekile akudalwanga ngesivinini esiphansi, futhi i-turbocharger encane iphendula ngokushesha kakhulu ekucindezeleni i-pedal yegesi.

Emiklamo enjalo, asikho isidingo sejometri ye-turbine eguquguqukayo.engavamile ukusetshenziswa ezinjinini zikaphethiloli. Futhi nokho isici esiyinhloko se-twin-scroll turbocharged injini ukusabela okusheshayo kakhulu ukwengeza igesi. Kungashiwo ngokungangabazeki ukuthi lolu hlobo lwe-turbocharger luqeda kangcono umcimbi we-turbolag.

Enye yezingqalabutho ekusebenziseni uhlelo lwe-twin-scroll turbo yi-BMW. esebenzisa igama elithi Twin Power Turbo kumayunithi ayo. Kuyaphawuleka lapha ukuthi akukho lutho oluvimbela ukusetshenziswa kwama-turbocharger amabili kuma-twin-head engines njengama-V8. Esinye isibonelo iFord, esebenzise i-twin-scroll turbocharger ku-sporty Focus RS. Abake bashayela le moto bayazi ukuthi injini yayo ishesha kangakanani uma ifakwa uphethiloli nokuthi inamandla kangakanani kuwo wonke ama-rev range. Sekwanele ukuthi le 2,3-litre kaphethroli ikhiqiza amandla afinyelela ku-440 Nm ukusuka ku-2000 iye ku-4500 rpm. Enye inkampani esebenzise i-twin-scroll turbocharger yiLexus. Kwi-NX injini engu-2 litre kaphethroli.
