Injini ye-Opel Z20LET
Okuqukethwe
Iyunithi yamandla angu-20 litre turbocharged i-Z2000LET yaqala ukuphuma emgqeni wokukhiqiza ngo-XNUMX eJalimane. Injini yenzelwe amamodeli adumile we-Opel OPC futhi yafakwa ku-Astra G, Zafira A, kanye naseTarga Speedster.
Injini kaphethiloli yayisekelwe kuyunithi yamalitha amabili eyayidingeka ngaleso sikhathi - i-X20XEV. Ukushintsha iqembu le-cylinder-piston kwenze kwaba nokwenzeka ukukhulisa isilinganiso sokucindezela sibe amayunithi angama-8.8, okube nomthelela omuhle ekusebenzeni kwenjini ene-turbocharged.
I-Z20LET ithole ikhanda lensimbi elicishe lingashintshiwe elinama-diameter alandelayo amavalvu: 32 kanye no-29 mm, umthamo kanye ne-exhaust, ngokulandelana. Ubukhulu bomhlahlandlela we-poppet valve buyi-6 mm. Ama-camshaft athole amapharamitha alandelayo: isigaba: 251/250, lift: 8.5/8.5 mm.
Imifanekiso ye-Z20LET
Izinjini ezivuthayo zangaphakathi ezingama-Z20LET ezinama-litre amabili ezinamandla afinyelela ku-200 hp zazifakwe i-Bosch Motronic ME 1.5.5 control unit kanye ne-Borgwarner K04-2075ECD6.88GCCXK turbine, ekwazi ukumpompa ifike kubha engu-0.6. Lokhu bekwanele impela ukufinyelela ku-5600 hp ku-200 rpm. Ubuningi bokukhipha imibhobho endaweni evulekile ngu-355 cc.

*Inombolo yenjini itholakala kuBC lapho kuhlangana khona u-gearbox, ngaphansi kwendawo yokuhluza uwoyela.
Ngo-2004, kwavela ukuguqulwa okubili kwe-Z20LET - Z20LER ne-Z20LEL, umehluko omkhulu owawuyiyunithi yokulawula ye-Bosch Motronic ME 7.6. Umehluko kuphela phakathi kwemikhiqizo emisha kwakuyizinguqulo ze-firmware zeyunithi efanayo. Lezi zinjini zifakwe ku-Opel Astra H ne-Zafira B izimoto.
Injini ye-Z20LET yaqala ukukhiqizwa kuze kube ngu-2005, okwathi ngemva kwalokho kwaqala ukukhiqizwa kwenjini enamandla nakakhulu - i-Z20LEH, eyahluke kakhulu kumanduleli ayo emigodini, induku yokuxhuma eqinisiwe neqembu le-piston, i-flywheel, i-cylinder head gasket, igesi namafutha. amaphampu, ama-injection, kanye nesistimu yokukhipha umoya. , kanye ne-turbine.
Ngo-2010, ukukhiqizwa kwe-serial kwezinjini ezivuthayo zangaphakathi zomndeni wakwa-Z kwaqedwa. Bathathelwe indawo yiyunithi eyaziwayo ye-A20NFT.
Izinzuzo kanye nokuwohloka okuvamile kwe-Z20LET
Плюсы
- Amandla.
- Torque.
- Amathuba wokushuna.
Минусы
- Ukusetshenziswa kukawoyela okuphezulu.
- I-exhaust eningi.
- Ukuvuza kwamafutha.
Enye yezinkinga ezivame kakhulu nge-Z20LET ukushiswa kwamafutha okubhanana. Uma injini iqala ukubhema futhi idle uwoyela ngokweqile, cishe isizathu salokhu sisezigxivizweni zamavalvu.
Isivinini esintantayo nomsindo kungase kubonise ukwakheka kokuqhekeka ku-multifold exhaust. Yiqiniso, ungakwazi ukulungisa le nkinga ngokushisela, kodwa ukufaka i-manifold entsha kuzothembela kakhulu.
Ukuvuza kukawoyela kungenye yezinkinga ezivame kakhulu ngezinjini ze-Z20LET. Kungenzeka ukuthi i-gasket yekhava yesilinda iyavuza.
Amayunithi amandla e-Z20LET ane-timing belt drive, okumele ishintshwe njalo ngamakhilomitha ayizinkulungwane ezingu-60. Uma ibhande lesikhathi liphuka, i-Z20LET igoba i-valve, ngakho-ke kungcono ukungalibali ukushintshwa.
Shintshanisa amasheya Z20LET
Inketho evame kakhulu yokwandisa ukusebenza kwamandla kwe-Z20LET ukukhanya kweyunithi yayo yokulawula. Ukushintsha uhlelo kuzonyusa amandla abe ngu-230 hp. Kodwa ukuze yonke into isebenze ngokuthembekile, kungaba ngcono ukwengeza i-intercooler, ukusika ama-catalysts futhi ulungiselele iyunithi yokulawula yakho konke lokhu. Ngemuva kokukhwabanisa okunjalo, imoto izoziphatha ngokushesha kakhulu, ngoba amandla ayo aphezulu azofinyelela ku-250 hp.
Ukuqhubekela phambili endleleni yokushuna i-Z20LET, ungakwazi “ukushintsha” i-turbine usuke ekulungisweni kwe-LEH uye enjinini. Uzodinga futhi ama-injection e-OPC, iphampu ye-fuel Walbro 255, imitha yokugeleza, i-clutch, i-intercooler, i-exhaust ngaphandle kwesiguquli se-catalytic, kanye-ke, ukusethwa kweyunithi yokulawula izinga eliphezulu.
isiphetho
Ngokuvamile, singasho ukuthi injini ye-turbo ye-Z20LET iyiyunithi ehloniphekile futhi isasebenza kahle, yebo, uma isetshenziswa njalo, isebenzisa izinto ezisetshenziswayo zangempela noketshezi, ithululela uphethiloli omuhle futhi ayishayeli "kuze kube sekupheleni" yamakhono ayo.
