Injini yakwa-Opel 1,6 SIDI Turbo Ecotec (125 no-147 kW)
Imoto yokuqala ukuthola injini entsha engu-1,6 SIDI turbocharged injektha eyi-Opel Cascada eshintshwayo. Ngokusho kwe-automaker, le njini kufanele ibe umholi ekilasini layo maqondana nokusetshenziswa, ukusebenza, kanye namasiko okusebenza.
Injini yokuqala yakwa-Opel eyayinomjovo oqondile kaphethroli kwaba yizinjini eziyi-2,2 kW 114 ECOTEC ezine-cylinder ngo-2003 kumamodeli akwaSignum naseVectra, kamuva asetshenziswa kwiZafira. Ngo-2007, i-Opel GT eshintshwayo yathola injini yokuqala engu-2,0 litre turbocharged four-cylinder direct injection engine ene-194 kW. Ngemuva konyaka, le njini yaqala ukufakwa kwi-Insignia ngezinguqulo ezimbili ngamandla angu-162 kW no-184 kW. I-Astra OPC entsha ithole inguqulo enamandla kakhulu enamandla angama-206 kW. Amayunithi ahlanganiswe eSzentgotthard, eHungary.
Injini engu-1,6 SIDI (spark ignition direct injection = spark ignition direct fuel injection) inendawo engu-1598 cc. Bona futhi, ngaphezu komjovo oqondile, futhi ifakwe uhlelo lokuqala / lokumisa. Le njini itholakala ngezinhlobo ezimbili zamandla i-1,6 Eco Turbo enamandla angu-125 kW netorque ephezulu engu-280 Nm ne-1,6 Performance Turbo eno-147 kW netorque ephezulu engu-300 Nm. Uhlobo lwamandla aphansi lwenzelwe ukusetshenziswa kukaphethiloli, ine-torque ephezulu ngejubane eliphansi futhi iyaguquguquka. Uhlobo olunamandla ngokwedlulele lwenzelwe abashayeli abashisekayo abangasabi ukuzuza kakhulu kubaba wabo.
Enkabeni yenjini entsha ye-SIDI ECOTEC Turbo ibhulokhi entsha yensimbi esakazwayo ekwazi ukumelana nokucindezela okuphezulu kakhulu kwesilinda kufika kumabha angu-130. Ukuze kuncishiswe isisindo, le block iron iron yengezwa nge-aluminum crankcase. I-injini ye-injini yenziwa ngokusebenzisa ubuchwepheshe bokuphonsa odongeni oluncane, okuvumela imisebenzi ehlukahlukene kanye nezakhi ukuthi zihlanganiswe ngqo ekubunjweni, okunciphisa isikhathi sokukhiqiza. Umqondo wezinto ezishintshayo wenza kube lula ukusebenzisa injini entsha kumamodeli ahlukene. Izinjini zibuye zifakwe ama-balance shaft, okuyiwona kuphela asesigabeni sazo kuze kube manje. Amashafu amabili okulinganisa atholakala odongeni olungemuva lwe-cylinder block futhi aqhutshwa iketango. Inhloso ye-counter-rotation shafts ukuqeda ukudlidliza okwenzeka ngesikhathi sokusebenza kwenjini enamasilinda amane. Izinguqulo ze-Eco Turbo kanye ne-Performance Turbo ziyehluka kumapiston asetshenzisiwe, okuyigumbi elivuthayo elimise okukhethekile ekhanda lepiston. Indandatho yokuqala yepiston ine-PVD (Physical Vapor Deposition) enamathelayo enciphisa ukulahleka kokungqubuzana.
Ngaphezu kokushintshwa komklamo, umjovo oqondile kaphethiloli kumasilinda kunciphisa ukusetshenziswa kukaphethiloli (isb. I-spark plug ne-injector zitholakala maphakathi nekamelo lomlilo ekhanda lesilinda ukuqhubeka nokunciphisa ubukhulu bangaphandle. Lo mklamo usiza nokwenza ngcono ukufana noma ukubeka ingxube. Isitimela se-valve siqhutshwa ngeketanga elingenalondolozo, elicindezelwe ngogesi, futhi izingalo ze-pulley rocker ziqukethe imvume yokubacindezela.
Izinjini ze-1,6 SIDI zisebenzisa i-turbocharger eyakhelwe ngqo ezinjini zokukhipha injini. Lo mklamo usuzibonisile nezinye izinjini ze-Opel futhi ulusizo ngokwendawo yokungcola kanjalo nezindleko zokukhiqiza njengoba ulula uma uqhathanisa namaTurbo-Scroll turbocharger asetshenziswa ezinjinini ezinkulu. I-turbocharger yakhelwe inguqulo ngayinye yamandla ngokuhlukile. Ngenxa yomklamo owenziwe kabusha, injini ikhipha i-torque ephezulu ngisho nangemuva eliphansi. Futhi, umsebenzi wenziwe ukucindezela umsindo ongadingeki (ukushaya ikhwela, ukushaywa umoya, umsindo womoya ogeleza uzungeze ama-blade), kufaka phakathi ukubonga kuma-resonator aphansi nangaphezulu, ukuqhutshwa komoya okwenziwe kahle kanye nokuma kweziteshi zokungena. Ukuqeda umsindo wenjini uqobo, ipayipi le-exhaust liguquliwe, kanye nekhava enhlobonhlobo ye-valve ekhanda lesilinda, lapho kusetshenziswe khona izinto ezikhethekile zokucindezela nezimpawu ezimelana namazinga okushisa aphezulu we-turbocharger eseduze.
