Opel Z20LET cav
Ob-liter turbocharged Z20LET lub hwj chim chav tsev thawj zaug dov tawm ntawm lub rooj sib txoos kab nyob rau hauv 2000 nyob rau hauv lub teb chaws Yelemees. Lub cav tau npaj rau cov qauv nrov Opel OPC thiab tau teeb tsa hauv Astra G, Zafira A tsheb, nrog rau hauv Speedster targa.
Lub cav roj av tau ua raws li ob-liter chav tsev uas xav tau thaum lub sijhawm ntawd - X20XEV. Hloov lub tog raj kheej-piston pab pawg ua kom nws muaj peev xwm nce qhov sib piv rau 8.8 units, uas muaj txiaj ntsig zoo rau kev ua haujlwm ntawm lub cav turbocharged.
Z20LET tau txais yuav luag tsis hloov pauv cam khwb cia-hlau BC lub taub hau nrog cov kab hauv qab no: 32 thiab 29 hli, noj thiab tso pa, feem. Lub thickness ntawm poppet valve qhia yog 6 hli. Cov camshafts tau txais cov kev txwv hauv qab no - theem: 251/250, nce: 8.5 / 8.5 hli.

* Lub cav naj npawb yog nyob rau ntawm BC ntawm kev sib tshuam nrog lub gearbox, nyob rau hauv cov roj lim vaj tsev.
Hauv xyoo 2004, ob qhov kev hloov kho ntawm Z20LET tshwm sim - Z20LER thiab Z20LEL, qhov sib txawv tseem ceeb ntawm uas yog Bosch Motronic ME 7.6 tswj chav. Cov novelties txawv ntawm ib leeg xwb nyob rau hauv lub firmware versions ntawm tib lub thaiv. Cov cav no tau nruab rau ntawm Opel Astra H thiab Zafira B tsheb.
Lub Z20LET lub cev muaj zog nyob rau hauv ntau lawm kom txog rau thaum 2005, tom qab uas lub zus tau tej cov cav tseem muaj zog, lub Z20LEH, pib, uas txawv los ntawm nws cov thawj coj nyob rau hauv shafts, ib tug txhawb zog txuas pas nrig thiab piston pab pawg neeg, flywheel, lub tog raj kheej taub hau gasket, roj. thiab roj twj tso kua mis, injectors, lub tso pa tawm thiab lub turbine.
Nyob rau hauv 2010, serial zus tau tej cov turbocharged nyob rau hauv combustion xyaw ntawm lub Z tsev neeg thaum kawg ua tiav. Lawv tau hloov los ntawm lub npe nrov A20NFT chav tsev.
Qhov zoo thiab cov yam ntxwv tawg ntawm Z20LET
Yav tas los
- Lub Zog.
- Torque.
- Muaj peev xwm tuning.
Daim ntawv
- Kev siv roj ntau.
- Ib qho exhaus manifold.
- Roj xau.
Ib qho teeb meem feem ntau nrog Z20LET yog banal roj noj. Yog hais tias lub cav pib haus luam yeeb thiab haus cov roj yam tsis muaj kev ntsuas, feem ntau yuav yog vim li cas rau qhov no nyob rau hauv lub valve seals.
Floating ceev thiab suab nrov yuav qhia tau hais tias tsim ib qho tawg nyob rau hauv lub tso pa manifold. Tau kawg, koj tuaj yeem kho qhov teeb meem no los ntawm kev vuam, tab sis kev txhim kho lub manifold tshiab yuav txhim khu kev qha ntau dua.
Cov roj xau yog lwm qhov teeb meem feem ntau nrog Z20LET cav. Feem ntau yuav yog lub tog raj kheej taub hau gasket yog to.
Z20LET lub zog hluav taws xob muaj lub sijhawm tsav tsheb, uas yuav tsum tau hloov txhua txhua 60 txhiab mais. Nyob rau hauv qhov kev tshwm sim ntawm ib tug tawg sij hawm siv, Z20LET khoov lub valve, yog li nws yog zoo dua tsis txhob zawm nws nrog ib tug hloov.
Tuning Z20LET
Qhov kev xaiv tshaj plaws rau kev ua kom lub zog ua haujlwm ntawm Z20LET yog nyem nws lub ECU. Hloov qhov kev pab cuam yuav ua rau kom lub zog mus rau 230 hp. Tab sis txhawm rau kom txhua yam ua haujlwm tau ntseeg tau, nws yuav zoo dua ntxiv ib qho intercooler, txiav tawm cov catalysts thiab teeb tsa CU rau tag nrho cov no. Tom qab xws li manipulations, lub tsheb yuav coj sai dua, vim hais tias nws lub zog siab tshaj plaws yuav ncav cuag 250 hp.
Txhawm rau txav mus ntxiv raws li Z20LET txoj hauv kev, koj tuaj yeem "tshem" lub tshuab hluav taws xob los ntawm kev hloov kho LEH mus rau lub cav. Koj tseem yuav xav tau OPC injectors, Walbro 255 roj twj tso kua mis, lub ntsuas dej ntws, lub clutch, intercooler, lub tso pa tsis muaj lub hloov pauv catalytic, thiab tau kawg, chav tswj tau zoo.
xaus
Feem ntau, peb tuaj yeem hais tias Z20LET turbo engine yog ib chav tsev tsim nyog thiab tseem qhia tau hais tias nws tus kheej ua haujlwm tau zoo, tau kawg, yog tias nws ua haujlwm tsis tu ncua, cov khoom siv tseem ceeb thiab cov kua dej siv, ncuav roj zoo thiab tsis txhob tsav tsheb "ntawm txwv" ntawm kev muaj peev xwm.
