Injini ye-Nissan rb20det

Nissan rb20det motor kungokwalabo uchungechunge ethandwa amandla amayunithi - Nissan RB. Amayunithi alolu chungechunge aqala ukukhiqizwa ngo-1984. Yangena esikhundleni senjini ye-L20. Umanduleli we-rb20det yi-rb20de.

Lena inguqulo yokuqala yenjini evuthayo yangaphakathi, eyiyunithi ye-in-line yamasilinda ayisithupha ene-cast iron cylinder block kanye ne-crankshaft encane.

Injini ye-RB20DET yavela ngo-1985 futhi yaduma ngokushesha phakathi kwabashayeli. Ngokungafani ne-RB20DE, ithole ama-valve angu-4 isilinda ngasinye (esikhundleni sama-valve angu-2). Ibhulokhi yesilinda yayifakwe amakhoyili okuthungela ngamanye. Iyunithi yokulawula, i-intake system, ama-pistons, izinduku zokuxhuma kanye ne-crankshaft kwenziwe ukuthuthukiswa komklamo.

Ukukhiqizwa kwe-RB20DET kwakuzoqedwa ngemva kweminyaka engu-15 kuqalwe ukukhiqizwa. Kuphela ngo-2000, injini ayizange isebenze futhi yathathelwa indawo ezinye izinjini ezivuthayo zangaphakathi, njenge-RB20DE NEO. Esikhathini esisha sangaleso sikhathi, ukunakwa okukhethekile kwakhokhelwa ubungane bemvelo. I-control unit nayo ishintshiwe, i-cylinder head, intake kanye ne-crankshaft zenziwe zesimanje.

I-RB20DET nayo yakhiqizwa ngenguqulo ye-turbocharged. I-turbine ivuthela amabha angu-0,5. Enjinini ene-turbocharged, isilinganiso sokucindezelwa sehlisiwe saba ngu-8,5. Ngaphezu kwalokho, ama-nozzles, iyunithi yokulawula yashintshwa, enye i-cylinder head gasket yafakwa, i-crankshaft, izinduku zokuxhuma nama-pistons zashintshwa.

I-Nissan RB20DET ayidingi ukulungiswa kwe-valve, okuyihlukanisa nama-analogues ayo. Okuhlukile yinguqulo ye-NEO, ebingahlonyiswa ngama-hydraulic lifters. I-RB20DET inokushayela kwebhande. Ibhande lesikhathi lishintshwa njalo ngamakhilomitha ayizinkulungwane ezingama-80-100.

I-RB20DET	1998	180 - 215	180 (132)/6400 190 (140)/6400 205 (151)/6400 210 (154)/6400 215 (158)/6000 215 (158)/6400	226 (23)/3600 226 (23)/5200 240 (24)/4800 245 (25)/3600 265 (27)/3200

Inombolo yenjini itholakala eduze kwalapho kuhlangana khona injini no-gearbox ngezansi kwesokudla uma uyibuka ngaphambili emotweni. Uma ubhekwa phezulu, kufanele unake indawo ephakathi kwesihlangu senjini, i-exhaust manifold kanye namapayipi e-air conditioner, isithando somlilo.

Ukuthembeka kweyunithi

Injini ye-RB20DET ithembekile ngendlela emangalisayo, eye yavivinywa ngokuphindaphindiwe ekusebenzeni. Ukumelana nezinsiza nomthwalo kuyisici salo lonke uchungechunge lwe-RB lulonke. Ukunakekelwa okuvamile kuqinisekisa imayela elide ngaphandle kokuphazamiseka. Kunoma yikuphi, kuphela uphethiloli wekhwalithi ephezulu kanye namafutha enjini aqinisekisiwe avunyelwe ukusetshenziswa.

I-RB20DET ivamise ukuhamba noma ingaqali. Imbangela yokuphuka wukungasebenzi kahle kwamakhoyili okushisa. Amakhoyili anconywa ukuthi ashintshwe njalo ngamakhilomitha ayizinkulungwane eziyi-100, okungenziwa yibo bonke abashayeli bezimoto. Okunye okubi wukusetshenziswa kukaphethiloli. Kwimodi exubile, ifinyelela kumalitha ayi-11 ngebanga lika-100 km.

Ukugcinwa nokutholakala kwezingxenye ezisele

I-RB20DET ayikwazi ukulungiswa kuphela, kodwa ishuniwe. Ukuthuthukisa izici zobuchwepheshe esizindeni somphakathi kukhona lonke ulwazi oludingekayo. Isibonelo, inethiwekhi ine-pinout "yengqondo" yenjini. Futhi kuyiqiniso impela, ngokusekelwe olwazini olutholakala ku-inthanethi, ukusetha i-dpdz.

Ukugcinwa kubonakaliswa kukho konke. Isibonelo, i-resistor yokudonsa eza nenguqulo yesitoko yemoto ingasuswa ngokuphelele. Kulesi simo, ama-injection omdabu ashintshwa nge-analogue esuka ku-1jz-gte vvti. Ama-injection e-GTE awadingi ukumelana okwengeziwe. Ngaphezu kwalokho, intengo yezingxenye iyathengeka impela.

Uma kunesidingo, ungasetha kalula izilungiselelo ze-kxx (i-valve engenzi lutho). Ukuze wenze lokhu, udinga ukufudumala imoto ibe ngu-80 degrees Celsius, uye esigabeni sokubonisa idatha bese uchofoza ukuhlolwa okusebenzayo, chofoza ku-QALA (isigaba sokulungiswa kwe-Base Idle). Ngemuva kokuthi udinga ukuvula ibhawodi lokulungisa libe ngu-650 ukuze uthole u-gearbox ozishintshayo noma ufinyelele ku-600 rpm ukuze uzidlulisele ngeminwe. Ekugcineni, esigabeni sokulungiswa kokungenzi lutho kwe-Base, chofoza okuthi MISA bese uchofoza inkinobho ethi Sula Ukuzifunda ekuhlolweni okusebenzayo.

Izingxenye ezisele ze-RB20DET cishe zihlala zithengiswa. Isibonelo, i-motor scythe ithengwa ngaphandle kwezinkinga, kuyilapho kunzima kakhulu ukuyithola kwamanye amamodeli. Futhi ezinsizeni ezinkulu zemoto, ezimweni ezimbi kakhulu, kuma-disassemblies noma ezitolo ze-intanethi, noma iyiphi ikhithi yokulungisa ihlale ikhona. Akukho okuncane okutholakalela ukudayiswa kwe-pump gur kanye nokuhanjiswa okwenziwa ngesandla.

Ukushuna i-RB20DET ngokwayo kunengqondo, njengoba injini inomkhawulo wokuphepha. Imininingwane ithuthukiswa ngokukhushulwa phezulu. Lesi sici sihlukanisa injini evuthayo yangaphakathi ku-RB20DE efanayo ne-RB20E. Ukufaka kuma-camshaft athuthukisiwe akamuva nezinye izingxenye kuwukuchitha isikhathi.

I-RB20DET ene-turbocharged isabalele futhi imisa ukushintsha eduze kwendlela. Ngenhloso enjalo, i-turbine yesitoko ayifanele, ekwazi ukuletha ukucindezela okukhulu kwe-0,8-0,9 bar. I-turbocharger efanayo inyusa amandla aze afike ku-270 horsepower. Ukuze usebenze kahle kakhulu, kufakwa amanye amakhandlela, iphampu evela ku-GTR, isilawuli se-boost, i-exhaust egeleza ngokuqondile, ipayipi eliphansi, i-wastegate, i-Skyline GTR intercooler, imibhobho evela ku-RB26DETT 444 cc/min.

Uma uthengiswa ungathola ikhithi ye-turbo eseyenziwe ngomumo yenjini eyenziwe ngamaShayina. Kufakwe ngaphandle kokuhlupheka. Iyunithi ikhiqiza amandla angakanani? Amandla amahhashi angu-350, kodwa nge-caveat ukuthi ukwethembeka kwekhithi enjalo ye-turbo kuyangabazeka futhi kungenzeka ukuthi izohlala isikhathi esifushane.

Okunye okubhekwayo wukwenyuka kwenjini isuka ku-2,05 litres iye ku-2,33 litres. Ngale njongo, i-cylinder block inesithukuthezi kuze kufike ku-81 mm. Ngemva kwalokho, pistons kusukela Toyota 4A-GZE efakwe. Ngemuva kokukhwabanisa okungeyona into entsha ngokombono wezobuchwepheshe, ivolumu yenjini ikhuphuka ibe amalitha angu-2,15.

Ukuze uthole amalitha angu-2,2, ibhulokhi inesithukuthezi ku-82 mm, futhi i-Tomei pistons ifakiwe. Kukhona futhi inketho usebenzisa ama-piston ajwayelekile. Ngesikhathi esifanayo, izinduku zokuxhuma nama-crankshafts avela ku-RB25DET afakiwe. Kulesi simo, umthamo uhlala ezingeni lika-2,05 amalitha.

Uma ushintsha ama-piston nge-4A-GZE, okukhiphayo kungamalitha angu-2,2. Ivolumu ikhuphuka ibe amalitha angu-2,1 lapho kufakwa izinduku zokuxhuma kanye ne-crankshaft esuka ku-RB26DETT. Ukusetshenziswa okwengeziwe 2,3A-GZE pistons kuzosiza ukwandisa umthamo injini enjalo 4 amalitha. I-Tomei 82mm pistons kanye nezinduku zokuxhuma ze-crankshaft ze-RB26DETT zinikeza ukugudluka okungamalitha angu-2,33.

Imaphi amafutha okugcwalisa injini

Umenzi uncoma ukusebenzisa uwoyela Nissan 5W40 original. Eqinisweni, ukusetshenziswa koketshezi olunjalo kukuvumela ukuthi ugcine injini ihlanzekile isikhathi eside, kusiza ukuqeda ukusetshenziswa kwamafutha kanye nemfucuza ekusebenzeni kwayo. Kuvunyelwe futhi ukusebenzisa amafutha okwenziwa nge-viscosity ye-5W50. Kubakhiqizi, i-Liquid Molly (10W60) ne-Mobile (10W50) kwesinye isikhathi iyanconywa.
