Enjene ea disele ea BMW 50d tri-turbo e sebetsa joang?
Haeba litsamaiso tse peli tsa turbo e le kopano e tsejoang ka tatellano kapa e ts'oanang, ho lokela ho hlokomeloa lehlakore la tekheniki la tri-turbo ea BMW, e kopanyang mahlale a mabeli hanyane. Ka kopo hlokomela, haeba u sa tsebe letho ka li-turbocharger, ke u mema hore u shebe mona.
Enjene ee ea li-turbo tse tharo e sebetsa joang?
Pele ho tsohle, hoa lokela ho hlokomeloa hore sistimi ena ea supercharging e na le li-turbine tse peli tse nyane (1 le 3 setšoantšong) tse nang le geometry e fapaneng, hammoho le turbocharger e tloaelehileng (2 setšoantšong). E 'ngoe le e' ngoe ea morao-rao e etsa hore ho be le lebelo le itseng, ebe li fumanoa ka mokhoa o tsitsitseng ka mekhoa e phahameng (hantle, haeba u ka e bitsa lebelo le phahameng, hobane li-diesel ha li ee holimo haholo ...).
Ka li-revs tse tlase, tse ka tlase ho 1500 rpm, turbo ea pele (e 'ngoe ea tse peli tse nyenyane tse fapaneng tsa geometry) e kōptjoa ke mouoane (moea o hloekileng o kenang ka ntle o ntse o feta ka har'a turbo e kholo). Leha e so sebetse sebakeng sena sa lebelo). Joale, ho qala ka 1500 rpm, e kholo e boetse e raha, hobane ho phalla ha metsi hona joale ho lekane ho e noa. Hopola hore li-turbine tse tharo ha li sebetse hammoho ho tloha qalong ea mokhoa, hobane tabeng ena ho phefumoloha ha ho bohlokoa ka ho lekaneng bakeng sa mosebetsi oa li-compressor tse tharo. Qetellong, ka 2500 rpm, ea boraro e ka qetella e qala ho sebetsa ka lebaka la ho buloa ha damper (e bitsoang bypass), e lumellang hore khase ea ho tsoa e fepeloe ho turbocharger ena (hobane ke u hopotsa hore ke matla a u lumellang ho khanna. enjene). turbo ke "moea" o hlahisoang ke likhase tse tsoang).
Ho ea ka pono ea meralo, re ka nahana ka li-turbine tsa 1 le 2 li le ka tatelano mabapi le tse ling, ha li-turbine tsa 1 le 3 (tse peli tse nyane) li tšoana.
Qalong, phallo ea khase ea ho qeta e leka-lekane, kahoo turbine e nyenyane e nka mohato oa pele oa ho matlafatsa.
E se e ntse e le 1500 rpm, enjene e hlahisa torque ea 650 Nm!
Enjene e hlahisa 740 Nm (!) Ho tloha 2000 ho ea ho 3000 rpm, e tsotehang ha e bapisoa le ("feela") 381 hp e hlahisoang.
