Engine Nissan SR20De

Injini "Nissan SR20De" - woimira banja lalikulu la magawo mphamvu mafuta a kampani Japanese, ogwirizana ndi index SR. Voliyumu ya injini zimenezi unachokera 1,6 mpaka 2 malita.

Chidziwitso chachikulu cha ma motors awa ndi mutu wa aluminiyamu ya silinda ndi chitsulo, kwenikweni, chipika cha silinda. Izi injini kuyaka mkati (ICE) anapangidwa kuchokera 1989 mpaka 2007.

Manambala omwe ali polemba gawo lamagetsi amawonetsa kukula kwa injini. Ndiko kuti, ngati mtundu wa galimoto - SR18Di, voliyumu yake ndi malita 1,8. Choncho, kwa injini SR20De injini kusamutsidwa ndi wofanana malita awiri.

Mndandanda wa injini za SR ndi, makamaka, injini za-lita ziwiri za mndandanda uwu, zinayikidwa pa mndandanda waukulu wa magalimoto okwera opangidwa ndi Nissan m'zaka za m'ma 90 "zero".

Mbiri ya injini ya Nissan SR20De

Pakati pa magawo onse amphamvu a mndandanda wa SR, SR20De ndi yotchuka kwambiri, ndipo wina akhoza kunena kuti wotchuka m'dziko lathu. Ma motors awa adayikidwa pamtundu wachisanu ndi chitatu wa Nissan Bluebird, womwe udatumizidwa mwachangu ku USSR, kenako ku Russia, ndi ogulitsa imvi kapena kungoti distillers.

Asanabwere injini izi, mu gawo la 2-lita mphamvu mayunitsi Japanese opangidwa CA20. Injini iyi inali yolemetsa kwambiri, malinga ndi kulemera kwake, chifukwa chipika chake ndi mutu wake unali ndi chitsulo chosungunula. Mu 1989, ma SR20 opepuka, aluminiyamu adayikidwa pa Bluebirds, omwe anali ndi phindu pamayendedwe amagalimoto komanso magwiridwe ake. Komanso, chifukwa cha chuma ndi ntchito zapamwamba, injini zoyaka mkatizi zinali ndi jekeseni wa mfundo zambiri ndi ma valve anayi pa silinda.

Kuyambira pachiyambi cha kupanga, chivundikiro cha valve chofiira chinayikidwa pamagetsi awa. Pachifukwa ichi, ma motors adalandira dzina la SR20DE Red top High port. Ma ICE awa adayima pamzere wa msonkhano mpaka 1994, pomwe adasinthidwa ndi injini za SR20DE Black top Low port.

Kuchokera m'malo mwake, kuwonjezera pa chivundikiro chakuda cha valve, mphamvu iyi idasiyanitsidwa ndi njira zatsopano zolowera mutu wa silinda (mutu wa silinda). 240/240 camshaft yatsopano (yomwe idayamba kale inali ndi 248/240 camshaft) ndi njira yatsopano yotulutsa mpweya yokhala ndi mapaipi a 38mm (doko la SR20DE Red top High linali ndi mapaipi a 45mm). Injini iyi idayima pamzere wa msonkhano mpaka 2000, ngakhale kuti sizinasinthidwe, mu 1995 pagalimoto idawonekera camshaft yatsopano 238/240.

Mu 2000, doko la SR20DE Black top Low lidasinthidwa ndi ICE yokweza ya SR20DE. Mbali zazikulu za mphamvu iyi zinali zoponya miyala ndi akasupe atsopano obwerera. Zosintha zina zomwe ziyenera kukumbukiridwa ndi ma pistoni osinthidwa pang'ono, crankshaft yopepuka komanso kufupikitsa kolowera. Kusintha uku kudapangidwa mpaka 2002. Pambuyo pake, injini zam'mlengalenga za SR20DE zidayimitsidwa. Komabe, mitundu ya turbocharged ya injini iyi idapitilirabe kupangidwa ndipo mbiri yawo idzakambidwa pansipa.

Mbiri yama injini a turbocharged SR20DET

Pafupifupi nthawi yomweyo ndi injini mwachibadwa aspirate, mtundu wake turbocharged anaonekera, wotchedwa SR20DET. Mtundu woyamba, ndi fanizo ndi injini mwachibadwa aspirated, amatchedwa SR20DET Red pamwamba. ICE iyi idapangidwa, monga mtundu wake wam'mlengalenga, mpaka 1994.

Galimoto iyi inali ndi turbine ya Garrett T25G, yomwe imatulutsa mphamvu ya 0,5 bar. Kukakamiza uku kunapangitsa kuti pakhale mphamvu ya 205 hp. pa 6000 rpm. Makokedwe a injini kuyaka mkati anali 274 NM pa 4000 rpm.

Pofuna kupulumutsa moyo wa injini, chiŵerengero cha psinjika chinachepetsedwa kufika 8,5 ndipo ndodo zogwirizanitsa zinalimbikitsidwa.

Kufanana ndi mphamvu ya unit iyi, mu 1990 inawoneka mtundu wamphamvu kwambiri, ndi mphamvu ya 230 hp. pa 6400 rpm ndi makokedwe a 280 Nm pa 4800 rpm. Zinali zosiyana ndi zomwe zidalipo kale ndi turbine yosiyana ya Garrett T28, yomwe idatulutsa kukakamiza kwa bar 0,72. Komanso, kuwonjezera pa izi, zosintha zotsatirazi zidapangidwa kugawo lamagetsi. Iye analandira camshaft 248/248 osiyana, zina jekeseni mafuta mphamvu 440 cm³ / mphindi, nozzles mafuta ena, crankshaft, ndodo kulumikiza ndi mabawuti yamphamvu mutu.

Mofanana ndi Baibulo la mumlengalenga, m'badwo wotsatira wa unit mphamvu anaonekera mu 1994. Analandira dzina Nissan SR20DET Black pamwamba. Kuwonjezera pa chivundikiro chakuda cha valve, chomwe chinakhala chizindikiro cha injini iyi, inalinso ndi kafukufuku watsopano wa lambda ndi pistoni. Kuphatikiza apo, njira zolowera ndi zotuluka zidasinthidwa, komanso mawonekedwe apakompyuta omwe ali pa bolodi adasinthidwa.

Mtundu wosiyana pang'ono, wamphamvu kwambiri wa injini iyi unatulutsidwa pagalimoto yamasewera ya Nissan S14 Silvia. Galimoto iyi inali ndi injini ya 220 hp. pa 6000 rpm ndi makokedwe a 275 Nm pa 4800 rpm.

Komabe, mtundu wapamwamba kwambiri wagawo lamagetsi udayikidwa pa m'badwo wotsatira, wachisanu ndi chiwiri Sylvia, womwe unali ndi index ya S15. Injini yagalimoto iyi inali ndi turbo ya Garrett T28BB yokhala ndi choziziritsa kukhosi chomwe chidapanga kukakamiza kwa bar 0,8. Komanso, anali okonzeka ndi mononozzle ndi mphamvu 480 cm³ / min. Pambuyo wamakono, injini kuyaka mkati anayamba mphamvu 250 hp. pa 6400 rpm ndipo anali ndi makokedwe a 300 Nm pa 4800 rpm.

Mitundu ina iwiri ya SR20DET inali pa ngolo yodziwika bwino ya Nissan Avenir. Makinawa adapangidwa nthawi imodzi, mphamvu ziwiri, ma unit awiri-lita okhala ndi mphamvu ya 205 ndi 230 hp. Ma motors awa adatchedwa Nissan SR20DET Silver top.

Komabe, mtundu wamphamvu kwambiri wa injini Nissan SR20 anaikidwa, kale m'zaka za m'ma 21, pa odziwika bwino "Nissan X-Trail GT" crossover. Zowona, mtundu uwu wa crossover sunagulitsidwe mwalamulo ku Russia.

Chifukwa chake, mtundu uwu umatchedwa SR20VET ndipo udayikidwa pam'badwo woyamba wa X-Trails pamsika waku Japan. Baibulo ili, monga m'badwo woyamba wa crossover, anapangidwa kuchokera 2001 mpaka 2007. ICE iyi idapanga mphamvu ya 280 hp. pa 6400 rpm ndipo anali ndi makokedwe a 315 Nm pa 3200 rpm. Pazinthu zamapangidwe amagetsi awa, ndikofunikira kudziwa ma camshafts 212/248 ndi turbine ya Garrett T28, yokhala ndi mphamvu yowonjezereka ya 0,6 bar.

Pamapeto pa nkhani ya mbiri ya injini Nissan SR20De, tiyenera kunena kuti wakhala ambiri pakati pa mndandanda lonse SR.

Kudalirika kwagalimoto

Payokha, ziyenera kunenedwa za gwero la injini iyi, monga mayunitsi ambiri a nthawi imeneyo, omwe amapangidwa m'dziko la dzuwa lotuluka, amakhala pafupifupi muyaya. Gulu lawo la pistoni, mosavuta, limapita makilomita theka la milioni kapena kuposa. Mwa kuyankhula kwina, injini zoyaka zamkatizi zili ndi gwero lomwe ndi lalitali kwambiri kuposa gwero la matupi agalimoto omwe adayikidwapo.

Pazovuta zochepa kwambiri pamagawo amagetsi awa, kulephera msanga kwa wowongolera liwiro lopanda ntchito komanso sensa yotulutsa mpweya wambiri imadziwika. Mavutowa amayamba makamaka chifukwa cha kuchepa kwa mafuta m'dziko lathu.

Chabwino, kuwonjezera kudalirika kwapadera kwa gulu la pisitoni, ubwino wa ma motors awa ndi kusowa kwa lamba pamakina oyendetsa nthawi. Ma motors awa ali ndi camshaft unyolo pagalimoto, ndipo unyolo nawonso uli ndi gwero la makilomita 250 - 300.

Ndi mafuta amtundu wanji oti utsanulire

Monga ma motors onse a kampani, Nissan SR20 ndi wodzichepetsa kwambiri ku mafuta omwe amagwiritsidwa ntchito. Mafuta otsatirawa a API angagwiritsidwe ntchito mu injini iyi:

• Zamgululi 5W-20
• Zamgululi 5W-30
• Zamgululi 5W-40
• Zamgululi 5W-50
• Zamgululi 10W-30
• Zamgululi 10W-40
• Zamgululi 10W-50
• Zamgululi 10W-60
• Zamgululi 15W-40
• Zamgululi 15W-50
• Zamgululi 20W-20

Ponena za opanga mafuta, kampani yaku Japan imalimbikitsa kugwiritsa ntchito mafuta awoawo. Ndipo ndizomveka kuzigwiritsa ntchito. Chowonadi ndi chakuti mafuta a Nissan sapezeka kuti agulitse kwaulere, amapezeka kwa ogulitsa ovomerezeka a kampaniyo ndipo ntchito yawo imatsimikizira kuti mudzadzaza mafuta oyambirira, omwe chizindikiro chake pa canister chikugwirizana ndi zomwe zili mkati mwake.

Chabwino, zokhudzana ndi zomwe zili pa canister, ndiye:

• Wamphamvu Save X - dzina la mafuta;
• 5W-30 - gulu lake malinga API;
• SN - nambala yoyamba muzolemba izi ikuwonetsa injini zomwe mafutawa ali;

1. S - limasonyeza kuti mafuta injini mafuta;
2. C - kwa dizilo;
3. N - amasonyeza nthawi ya chitukuko cha mafuta. Kupitilira apo kalatayo imachokera ku chilembo choyamba "A", ndi chamakono kwambiri. Mwachitsanzo, mafuta "N" anawonekera mochedwa kuposa mafuta ndi chilembo "M".
