Mu 2004, zosintha ziwiri za Z20LET zidawonekera - Z20LER ndi Z20LEL, kusiyana kwakukulu komwe kunali Bosch Motronic ME 7.6 control unit. Zatsopano zimasiyana wina ndi mzake kokha mumitundu ya firmware ya block yomweyo. injini izi anaika pa Opel Astra H ndi Zafira B magalimoto.
Z20LET galimoto anali kupanga mpaka 2005, kenako anayamba kupanga injini wamphamvu kwambiri Z20LEH, wosiyana ndi m'mbuyo mwake mu shafts, analimbitsa kugwirizana ndodo ndi pisitoni gulu, flywheel, yamphamvu mutu gasket, mafuta. ndi mapampu amafuta, ma nozzles, ndi makina otulutsa mpweya komanso turbine.
Mu 2010, kupanga siriyo wa injini kuyaka mkati turbocharged banja Z anatsirizika. Adasinthidwa ndi gawo lodziwika bwino la A20NFT.
Ubwino ndi kuwonongeka kwa mawonekedwe a Z20LET
Плюсы
- Mphamvu.
- Torque.
- Kuthekera kwa kukonza.
Минусы
- Kugwiritsa ntchito mafuta kwambiri.
- Kuchuluka kwa mpweya.
- Kutuluka kwa mafuta.
Imodzi mwamavuto omwe amapezeka kwambiri ndi Z20LET ndikudya mafuta a banal. Ngati injini iyamba kusuta ndikudya mafuta popanda muyeso, mwina chifukwa chake chagona pazisindikizo za valve.
Liwiro loyandama ndi phokoso likhoza kuwonetsa kupangika kwa mng'alu muutsi wochuluka. Zachidziwikire, mutha kukonza vutoli powotcherera, koma kukhazikitsa manifold atsopano kudzakhala odalirika kwambiri.
Kutuluka kwamafuta ndi ena mwamavuto omwe amapezeka kwambiri ndi injini za Z20LET. Nthawi zambiri cylinder head gasket ikutha.
Magawo amagetsi a Z20LET ali ndi lamba wanthawi, womwe uyenera kusinthidwa makilomita 60 aliwonse. Pakachitika lamba wanthawi yosweka, Z20LET imapindika valavu, kotero ndi bwino kuti musamangirire ndi m'malo mwake.
Kusintha kwa Z20LET
Njira yodziwika bwino pakuwonjezera mphamvu ya Z20LET ndikuwunikira ECU yake. Kusintha pulogalamuyo kumawonjezera mphamvu ku 230 hp.

Pambuyo m'njira imeneyi galimoto kuchita zinthu mofulumira kwambiri, chifukwa mphamvu zake pazipita kufika 250 HP.
Kuti mupitirire patsogolo pa njira yosinthira ya Z20LET, mutha "kuponya" turbine kuchokera pakusintha kwa LEH kupita ku injini. Mudzafunikanso majekeseni a OPC, pampu yamafuta ya Walbro 255, mita yothamanga, clutch, intercooler, utsi wopanda chosinthira chothandizira, komanso, chowongolera chapamwamba kwambiri.
Pomaliza
Kawirikawiri, tikhoza kunena kuti injini ya turbo ya Z20LET ndi yofunika kwambiri ndipo imadziwonetserabe bwino ikugwira ntchito, ndithudi, ngati ikugwiritsidwa ntchito nthawi zonse, zogwiritsidwa ntchito zoyamba ndi zamadzimadzi zimagwiritsidwa ntchito, kutsanulira mafuta abwino komanso osayendetsa " malire" a luso.
