Chekutanga, Chero kuenzanisa kwekuyerera kwemhepo kuburikidza neturbocharger compressor.
Sezvatinoziva tese, macompressor akashandiswa zvakanyanya senzira inoshanda yekuvandudza mashandiro uye kuderedza kuburitswa kweinjini dzedhiziri.Iyo inowedzera kuomesera yekuburitsa mirau uye inorema epositi gasi recirculation inogona kusundidzira mamiriro ekushanda kweinjini kumatunhu asina kunyatsoshanda kana asina kugadzikana.Pasi pemamiriro ezvinhu aya, yakaderera kumhanya uye yakakwira mitoro yekushanda yeinjini dzedhiziri inoda iyo turbocharger compressors kuti ipe mweya wakasimudzwa zvakanyanya pamitengo yakaderera yekuyerera, zvisinei, kuita kweturbocharger compressors kazhinji kunogumira pasi pemamiriro ekushanda akadaro.
Naizvozvo, kuvandudza turbocharger kunyatsoita uye nekuwedzera yakagadzikana yekushanda renji iri kuve yakakosha kune inogoneka yakaderera emission injini dzedhiziri.CFD simulations yakaitwa naIwakiri naUchida yakaratidza kuti musanganiswa wezvose zviri zviviri casing kurapwa uye variable inlet gwairira vanes inogona kupa yakafara mashandiro akasiyana nekuenzanisa kupfuura kushandisa imwe neimwe yakazvimirira.Iyo yakagadzika inoshanda renji inochinjirwa kudzikisa kuyerera kwemhepo kana iyo compressor kumhanya yakaderedzwa kusvika 80,000 rpm.Zvisinei, pa80,000 rpm, iyo yakagadzikana yekushanda inoshandiswa inova shoma, uye chiyero chekumanikidza chinova chakaderera;izvi zvinonyanya kukonzerwa nekuderedzwa tangential kuyerera pakubuda kwe impeller.
Chechipiri, iyo yemvura-kutonhora system ye turbocharger.
Kuwedzera kwenhamba yekuedza kwakaedzwa kuvandudza iyo yekutonhodza sisitimu kuitira kuti isimudze zvinobuda nekunyanya kushandiswa kwevhoriyamu inoshanda.Matanho akanyanya kukosha mukufambira mberi uku ishanduko kubva (a) mhepo kuenda kuhydrogen kutonhodza kwejenareta, (b) isina kunanga kunangana conductor kutonhora, uye pakupedzisira (c) hydrogen kuenda kumvura inotonhorera.Mvura inotonhorera inoyerera ichienda kune pombi kubva mutangi remvura iyo yakarongwa semusoro wetangi pane stator.Kubva papombi mvura inotanga kuyerera nemuinotonhorera, sefa, uye kudzvanywa kwevharuvhu yekudzora, yozofamba nenzira dzakafanana nemuma stator windings, main bushings, uye rotor.Pombi yemvura, pamwe chete nemvura inopinza uye yekubuda nayo, inosanganisirwa mumusoro wekubatanidza mvura inotonhorera.Nekuda kwesimba ravo re centrifugal, hydraulic pressure inotangwa nembiru dzemvura pakati pemabhokisi emvura nemakoiri pamwe chete neradial ducts pakati pemabhokisi emvura nepakati bore.Sezvambotaurwa, kusiyanisa kudzvinyirirwa kwembiru dzemvura inotonhora uye inopisa nekuda kwekukwira kwekushisa kwemvura kunoshanda semusoro wekumanikidza uye kunowedzera huwandu hwemvura inoyerera kuburikidza nemakoiri maererano nekuwedzera kwekushisa kwemvura kukwira uye simba re centrifugal.
