I ka makahiki 2004, ua ʻike ʻia ʻelua mau hoʻololi o ka Z20LET - Z20LER a me Z20LEL, ʻo ka ʻokoʻa nui o ia ka Bosch Motronic ME 7.6 mana mana. ʻOkoʻa nā mea hou mai kekahi i kekahi i nā mana firmware o ka poloka hoʻokahi. Ua hoʻokomo ʻia kēia mau ʻenekini ma nā kaʻa Opel Astra H a me Zafira B.
Hana ʻia ka mīkini Z20LET a hiki i ka makahiki 2005, a laila hoʻomaka ka hana ʻana i kahi mīkini ʻoi aku ka ikaika, ʻo ka Z20LEH, kahi ʻokoʻa mai kona mua i nā shafts, kahi lāʻau hoʻohui i hoʻoikaika ʻia a me ka hui piston, kahi flywheel, ke poʻo cylinder gasket, gasoline. a me nā ʻaila pauma, nā nozzles, a me kahi ʻōnaehana hoʻopau a me ka turbine.
I ka makahiki 2010, ua hoʻopau hope ʻia ka hana serial o nā ʻenekini hoʻoheheʻe kūloko turbocharged o ka ʻohana Z. Ua pani ʻia lākou e ka hui A20NFT kaulana.
Nā pōmaikaʻi a me nā hiʻohiʻona hiʻohiʻona o Z20LET
Плюсы
- Ka mana.
- Torque.
- Hiki ke hoʻopaʻa ʻia.
Минусы
- ʻO kaʻaila kiʻekiʻe.
- ʻO kahi pahu puka.
- Leʻa ʻaila.
ʻO kekahi o nā pilikia maʻamau me ka Z20LET ʻo ka ʻai aila banal. Inā hoʻomaka ka ʻenekini e puhi a ʻai i ka aila me ke ana ʻole, aia paha ke kumu o kēia ma nā sila valve.
ʻO ka holo wikiwiki a me ka walaʻau e hōʻike i ke kūkulu ʻia ʻana o kahi māwae i loko o ka pahu pahu. ʻOiaʻiʻo, hiki iā ʻoe ke hoʻoponopono i kēia pilikia ma ka welding, akā ʻoi aku ka hilinaʻi o ka hoʻokomo ʻana i kahi manifold hou.
ʻO nā ʻaila ʻaila kekahi o nā pilikia maʻamau me nā mīkini Z20LET. ʻO ka hapa nui paha e kahe ana ka pahu poʻo cylinder.
Loaʻa i nā mana mana Z20LET kahi kaʻa kāʻei manawa, pono e hoʻololi i kēlā me kēia 60 tausani mau kilomita. I ka wā i haki ʻia ke kāʻei manawa, hoʻopiʻi ka Z20LET i ka valve, no laila ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻole ʻana me kahi pani.
Hoʻokani Z20LET
ʻO ka koho maʻamau no ka hoʻonui ʻana i ka hana mana o ka Z20LET ʻo ia ka uila i kāna ECU. ʻO ka hoʻololi ʻana i ka papahana e hoʻonui i ka mana i 230 hp. Akā i mea e hana pono ai nā mea āpau, ʻoi aku ka maikaʻi o ka hoʻohui ʻana i kahi intercooler, ʻoki i nā catalysts a hoʻonohonoho i ka CU no kēia mau mea āpau. Ma hope o ia mau manipulations, ʻoi aku ka wikiwiki o ke kaʻa, no ka mea, hiki i kona mana kiʻekiʻe ke hiki i 250 hp.
No ka neʻe hou aku ma ke ala hoʻokani Z20LET, hiki iā ʻoe ke "hoʻolei" i ka turbine mai ka hoʻololi LEH ma luna o ka ʻenekini. Pono ʻoe i nā injectors OPC, kahi pahu wahie Walbro 255, kahi mika kahe, kahi puʻupuʻu, kahi intercooler, kahi exhaust me ka ʻole o ka catalytic converter, a ʻoiaʻiʻo hoʻi, kahi mana mana kiʻekiʻe.
hopena
Ma keʻano laulā, hiki iā mākou ke ʻōlelo i ka Z20LET turbo engine he ʻāpana kūpono a hōʻike mau iā ia iho i ka hana ʻana, ʻoiaʻiʻo, inā e lawelawe mau ʻia, hoʻohana i nā mea hoʻohana mua a me nā wai, e ninini i ka ʻaila maikaʻi a ʻaʻole e hoʻokele "i ka palena. "o na hiki.
