Nissan RB20E injini
Injini ya Nissan RB20E idayambitsidwa mu 1984 ndipo idapangidwa mpaka 2002. Iyi ndiye mota yaying'ono kwambiri pagulu lonse la RB lodziwika bwino. Amakhulupirira kuti ndi m'malo mwa L20 yakale.
Ndi RB20E ndiye mtundu woyamba pamzere wonsewo. Analandira masilinda asanu ndi limodzi okonzedwa motsatizana mu chipika chachitsulo chachitsulo, ndi crankshaft yaifupi.
Pamwamba, wopanga amaika mutu wa aluminiyumu ndi shaft imodzi ndi ma valve awiri pa silinda. Kutengera m'badwo ndi kusinthidwa, mphamvu anali 115-130 HP.

Magalimoto okhala ndi injini ya RB20E
Mphamvu yopangira magetsi idakhazikitsidwa koyamba pagalimoto ya "Nissan Skyline" mu 1985, nthawi yomaliza idakhazikitsidwa pa Nissan Crew mu 2002, ngakhale galimotoyo idapangidwa mpaka 2009 pogwiritsa ntchito injini zina.
Mndandanda wamitundu yokhala ndi injini ya RB20E:
- Stegea - 1996-1998.
- Skyline - 1985-1998.
- Laurel - 1991-1997.
- Ogwira ntchito - 1993-2002.
- Cefiro - 1988-199
Chigawochi chakhalapo bwino pamsika kwa zaka 18, zomwe zimasonyeza kudalirika kwake ndi kufunikira kwake.
Kusintha
RB20E yoyambirira sizosangalatsa. Iyi ndi injini yapakatikati ya 6-silinda yokhala ndi magwiridwe antchito apamwamba. Mtundu wachiwiri umatchedwa RB20ET - inali injini ya turbocharged yomwe "inawomba" 0.5 bar.
Mphamvu ya injini idafika 170 hp. Ndiko kuti, Baibulo loyambirira linalandira kuwonjezeka kwakukulu kwa mphamvu. Komabe, zosintha zina ndi turbocharger anali ndi mphamvu ya 145 hp.
Mu 1985, Nissan adayambitsa RB20DE Ice, yomwe pambuyo pake idakhala yotchuka kwambiri pamzere. Chowoneka bwino kwambiri ndi mutu wa silinda wa 24-valve wokhala ndi ma coil oyatsira pawokha. Kusintha kwina kunachitikanso: dongosolo lodyera, crankshaft yatsopano, ndodo zolumikizira, ECU. injini izi anaika pa Nissan Skyline R31 ndi R32 zitsanzo Laurel ndi Cefiro, iwo akhoza kukhala ndi mphamvu mpaka 165 HP. Ma motors awa adapangidwa kwa nthawi yayitali ndipo adafalikira.
Mwa mwambo, kusinthidwa bwino kwambiri "Nissan" anaika 16V turbocharger, kupereka kuthamanga 0.5 mipiringidzo. Lachitsanzo amatchedwa RB20DET, chiŵerengero cha psinjika chinachepetsedwa kufika 8.5, ma nozzles osinthidwa, ndodo zolumikizira, pistoni, gasket ya silinda mutu. Mphamvu yamagalimoto inali 180-190 hp.
Panalinso mtundu wa RB20DET Silver pamwamba - iyi ndi RB20DET yomweyo, koma ndi dongosolo la ECCS. Mphamvu zake zidafika 215 hp. pa 6400 rpm. Mu 1993, unit iyi inatha, pamene Baibulo 2.5-lita anaonekera - RB25DE, amene akhoza kukhala ndi mphamvu yomweyo, koma popanda turbocharger.
Mu 2000, wopanga anasintha pang'ono injini za RB20DE kuti zigwirizane ndi makhalidwe ake muzinthu zachilengedwe. Umu ndi momwe kusinthidwa kwa NEO ndi zinthu zocheperako za zinthu zovulaza mu utsi zidawonekera. Analandira crankshaft yatsopano, mutu wa silinda wokweza, ECU ndi makina odyetserako chakudya, ndipo mainjiniya adathanso kuchotsa zonyamula ma hydraulic. Mphamvu ya injini sinasinthe kwambiri - 155 hp yemweyo. Chigawochi chimapezeka pa Skyline R34, Laurel C35, Stegea C34.
Ntchito
Mitundu yonse ya injini za RB25DE, kupatula NEO, sizifunikira kusintha kwa valve, popeza zili ndi ma compensators a hydraulic. Iwo adalandiranso lamba woyendetsa nthawi. Lamba liyenera kusinthidwa pambuyo pa makilomita 80-100 zikwi, koma ngati mluzu wokayikitsa ukuwonekera kuchokera pansi pa hood kapena liwiro likuyandama, m'malo mwake mungafunike.
Lamba wa nthawiyo akathyoka, ma pistoni amapindika valavu, zomwe zimatsagana ndi kukonzanso kwamtengo wapatali.
Kupanda kutero, kukonza injini kumabwera pamachitidwe okhazikika: kusintha mafuta, zosefera, kugwiritsa ntchito mafuta apamwamba kwambiri. Ndi kukonza bwino, injini izi kuphimba makilomita oposa 200 zikwi popanda kukonza lalikulu.
Mavuto
Mndandanda wonse wa RB, kuphatikizapo injini za RB25DE, ndizodalirika. Zopangira magetsizi zilibe mapangidwe olakwika komanso ukadaulo womwe ungayambitse kugawanika kwa block kapena zovuta zina zazikulu. Ma injini awa ali ndi vuto ndi coils poyatsira - amalephera, ndiyeno injini troit. Iwo akulimbikitsidwa kusinthidwa pambuyo 100 zikwi makilomita. Komanso, mndandanda wonse wa RB ndi wosusuka, kotero kuchuluka kwa gasi mukamayendetsa mumzinda kapena mumsewu sikuyenera kudabwitsa eni ake.
Ena onse mavuto ngati kutayikira mafuta kapena zinyalala ndi mmene ndi khalidwe la injini zonse kuyaka mkati. Kwa mbali zambiri, zimagwirizanitsidwa ndi ukalamba wachibadwa.
Kutsegula
Masters amanena kuti n'zotheka kupeza mphamvu zambiri kuchokera ku RB20DE, koma izi ndizowononga nthawi ndi ndalama. Ndizosavuta komanso zotsika mtengo kugula mgwirizano wa RB20DET ndi turbine, zomwe zimakupatsani mwayi wowonjezera mphamvu mwachangu.
Koma RB20DET ikhoza kusinthidwa kale. Chowonadi ndi chakuti sichigwiritsa ntchito turbocharger yabwino, yomwe imakhala yovuta kuyimba. Koma amatha "kukulitsa" mpaka 0.8 bar, yomwe imapereka pafupifupi 270 hp. Kuti tichite zimenezi, pa RB20DET amaika nozzles atsopano (kuchokera injini RB26DETT), makandulo, intercooler ndi zinthu zina.
Pali njira yosinthira turbine kukhala TD06 20G, yomwe idzawonjezera mphamvu zambiri - mpaka 400 hp. Palibe chifukwa chopitira patsogolo, chifukwa pali RB25DET mota yokhala ndi mphamvu yofananira.
Pomaliza
Injini ya Nissan RB20E ndi gawo lodalirika lomwe lili ndi gwero lalitali, lomwe tsopano latha. M'misewu ya ku Russia, pali magalimoto omwe ali ndi injini iyi pamayendedwe okhazikika. Komabe, mulimonsemo, chifukwa cha ukalamba wachilengedwe, gwero lawo likutha.
Zomwe zimagulitsidwa zimagulitsa ma injini a mgwirizano wa RB20E ofunika ma ruble 30-40 zikwi (mtengo womaliza umadalira chikhalidwe ndi mtunda). Pambuyo pazaka makumi angapo, ma motors awa akugwirabe ntchito ndikugulitsidwa, zomwe zimatsimikizira kudalirika kwawo.
