Nissan rb20det engine

Matoorka Nissan rb20det waxaa iska leh taxanaha caanka ah ee unugyada tamarta - Nissan RB. Unugyada taxanahan waxa la bilaabay in la soo saaro 1984kii. U yimid inuu beddelo mishiinka L20. Kii ka horreeyay ee rb20det waa rb20de.

Kani waa noocii ugu horeeyay ee matoorka gubashada gudaha, kaas oo ah unug lix-dhululubo ah oo khadka ku jira oo leh baloog dhululubo ah oo kabka ah iyo bir yar.

Matoorka RB20DET wuxuu soo muuqday 1985 wuxuuna isla markiiba caan ku noqday darawallada. Si ka duwan RB20DE, waxay heshay 4 valves per cylinder (halkii 2 valves). Baloogga dhululubada waxaa lagu rakibay gariiradaha shidda ee gaarka ah. Unugga kantaroolka, nidaamka qaadashada, biistoonada, isku xirka ulaha iyo shafka ayaa lagu sameeyay hagaajinta naqshadeynta.

Wax-soo-saarka RB20DET waxay ahayd in la joojiyo 15 sano kadib bilawga wax-soo-saarka. Kaliya 2000, matoorku wuxuu noqday mid aan khusayn waxaana lagu beddelay matoorada kale ee gubashada gudaha, sida RB20DE NEO. Waaga cusub ee wakhtigaas, waxa fiiro gaar ah loo lahaa saaxiibtinimada deegaanka. Unugga kantaroolka ayaa sidoo kale la beddelay, madaxa dhululubada, qaadashada iyo shafka ayaa la casriyeeyay.

RB20DET sidoo kale waxaa lagu soo saaray nooc turbocharged ah. Turbine-ku wuxuu kiciyaa 0,5 bar. Matoorka turbocharged, saamiga cadaadiska ayaa hoos loo dhigay ilaa 8,5. Intaa waxaa dheer, nozzles, unugga kantaroolka ayaa la beddelay, gaas kale oo madaxa dhululubo ah ayaa lagu rakibay, shafka, ulaha isku xirka iyo pistons ayaa la beddelay.

Nissan RB20DET uma baahna hagaajin waalka, taas oo ka soocaysa analogs-keeda. Waxa ka reeban waa nooca NEO, kaas oo aan ku qalabaysan wiish-biyoodyada. RB20DET waxay leedahay suunka. Suunka waqtiga ayaa la bedelayaa 80-100 kun kiiloomitir kasta.

Tilmaamaha Matoorka

Mashiinka	Mugga, cc	Awood, h.p.	Max. awood, hp (kW) / saacada rpm	Max. wareega, N/m (kg/m) / saacada rpm
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

Nambarka mishiinka wuxuu ku yaalaa meel u dhow meesha ay isku xiraan mishiinka iyo sanduuqa gear-ka ee dhinaca midig ee hoose marka laga eego dhinaca hore ee baabuurka. Marka laga eego xagga sare, waa inaad fiiro gaar ah u yeelataa aagga u dhexeeya gaashaanka mishiinka, qaybta qiiqa iyo tuubooyinka qaboojiyaha, foornada.

Isku halaynta unugga

Matoorka RB20DET waa mid si cajiib ah la isku halayn karo, kaas oo si isdaba joog ah loo tijaabiyay ficil ahaan. Ilaha iyo caabbinta culeysku waa sifada taxanaha RB oo dhan guud ahaan. Dayactirka joogtada ah wuxuu dammaanad qaadayaa masaafada dheer iyada oo aan burbursanayn. Si kastaba ha ahaatee, kaliya shidaal tayo sare leh iyo saliid matoorka la xaqiijiyay ayaa loo ogol yahay in la isticmaalo.

RB20DET inta badan wuu tagaa ama ma bilaabo. Sababta burburku waa cilad ku timid gariiradda dabka. Gariiradaha waxaa lagu talinayaa in la beddelo 100 kun kiiloomitir kasta, taas oo aysan samayn dhammaan darawallada. Khasaaro kale ayaa ah isticmaalka shidaalka. Habka isku dhafan, waxay gaartaa 11 litir 100 kiiloomitir.

Joogteynta iyo helida agabka agabka

RB20DET laguma hagaajin karo oo keliya, laakiin waa la hagaajiyay. Si loo hagaajiyo sifooyinka farsamada ee goobaha dadweynaha waxaa jira dhammaan macluumaadka lagama maarmaanka ah. Tusaale ahaan, shabakadu waxay leedahay meel ka mid ah "maskaxda" mishiinka. Sidoo kale waa arrin macquul ah, oo ku saleysan macluumaadka laga heli karo internetka, in la dejiyo dpdz.

Joogteynta ayaa lagu muujiyaa wax walba. Tusaale ahaan, iska caabinta dhibicda ee la socota nooca saamiga matoorka ayaa gebi ahaanba laga saari karaa. Xaaladdan oo kale, cirbadaha waddaniga ah waxaa lagu beddelaa analoog ka yimid 1jz-gte vvti. Cirbadaha GTE uma baahna iska caabin dheeraad ah. Waxaa intaa dheer, qiimaha qaybaha waa mid la awoodi karo.

Haddii loo baahdo, waxaad si fudud u dejin kartaa dejinta kxx (valve aan shaqayn). Si aad tan u samayso, waxaad u baahan tahay inaad ku diiriso baabuurka ilaa 80 darajo Celsius, aad qaybta Bandhigga Xogta oo guji tijaabada firfircoon, dhagsii START (qaybta Idle Adjustment section). Ka dib marka aad u baahato inaad u rogto bolt-ka hagaajinta 650 gudbinta tooska ah ama ilaa 600 rpm gudbinta gacanta. Ugu dambayntii, qaybta Is-habaynta Iidle ee Saldhigga, dhagsii JOOJI oo dhagsii badhanka Nafta Baro ee imtixaanka firfircoon.

Qaybaha kaydka ah ee RB20DET had iyo jeer waa iib. Tusaale ahaan, mishiinka mishiinka waxaa lagu iibsadaa dhib la'aan, halka ay aad u adag tahay in lagu helo noocyo kale. Sidoo kale adeegyada baabuurta waaweyn, xaaladaha aadka u daran, meelaha kala-duwan ama dukaamada online-ka ah, qalab kasta oo dayactir ah ayaa had iyo jeer la heli karaa. Ma jiro wax yar oo la heli karo iibka guriyaha matoorka iyo gudbinta gacanta.

Hagaajinta RB20DET lafteeda ayaa macno samaynaysa, maadaama matoorku leeyahay xad badbaado ah. Tilmaamaha waxaa lagu hagaajiyaa kor u qaadis. Habkani wuxuu ka soocaa matoorka gubashada gudaha ee isla RB20DE iyo RB20E. Ku rakibida kaamamayaashii ugu dambeeyay ee la hagaajiyay iyo qaybaha kale waa wakhti lumis.

Turbocharged RB20DET waa mid baahsan oo waxay dejisaa isdhaafsiga wadada dhinaceeda. Ujeedadaas oo kale, marawaxadaha kaydka ah kuma habboona, kaas oo awood u leh inuu keeno cadaadiska ugu badan ee 0,8-0,9 bar. Turbocharger la mid ah waxa uu kordhiyaa awooda ilaa ugu badnaan 270 hoos. Waxtarka weyn, shumacyo kale ayaa lagu rakibay, bamka GTR, kontaroolaha kor u kaca, qiiqa qulqulka tooska ah, tuubbada hoose, qashinka qashinka ah, qaboojiyaha Skyline GTR, tuubooyinka RB26DETT 444 cc / min.

Iibka waxaad ka heli kartaa qalab turbo ah oo diyaarsan oo loogu talagalay mishiinka Shiinaha lagu sameeyay. Lagu rakibay dhib la'aan Awood intee le'eg ayuu unuggani soo saaraa? 350 hooras, laakiin iyadoo laga digtoonaado in isku halaynta qalabka turbo noocan oo kale ah uu shaki ku jiro oo ay u badan tahay inay socon doonto muddo gaaban.

Tixgelinta goonida ah waa kororka awoodda injiinka laga bilaabo 2,05 litir ilaa 2,33 litir. Ujeedadaas awgeed, block dhululubo ayaa caajisay ilaa 81 mm. Intaa ka dib, pistons ka Toyota 4A-GZE ayaa lagu rakibay. Ka dib wax-is-daba-marineed oo aan sidaas ugu cusbayn dhinaca farsamada, mugga mishiinku wuxuu kordhiyaa ilaa 2,15 litir.

Si aad u hesho 2,2 litir, block ayaa caajisay ilaa 82 mm, pistons Tomei ayaa lagu rakibay. Waxa kale oo jira ikhtiyaar la isticmaalayo pistons caadiga ah. Isla mar ahaantaana, isku xirka ulaha iyo shafka laga bilaabo RB25DET ayaa la rakibay. Qaabkan, mugga ayaa ku sii jira heerka 2,05 litir.

Marka lagu beddelayo pistons 4A-GZE, wax soo saarku waa 2,2 litir. Mugga wuxuu kordhiyaa ilaa 2,1 litir marka isku xirka ulo iyo shaft ka RB26DETT la rakibay. Isticmaalka dheeraadka ah ee 2,3A-GZE pistons waxay gacan ka geysan doontaa kordhinta mugga mashiinka noocan oo kale ah ilaa 4 litir. Bisitoonada Tomei 82mm iyo RB26DETT ulaha isku xidha qaboojiyaha waxay siinayaan barakac 2,33 litir ah.

Waa maxay saliid lagu buuxiyo mishiinka

Soo saaruhu wuxuu ku talinayaa in la isticmaalo saliidda asalka ah ee Nissan 5W40. Ficil ahaan, isticmaalka dareeraha noocan oo kale ah wuxuu kuu ogolaanayaa inaad nadiifiso matoorka muddo dheer, waxay ka caawisaa in la baabi'iyo isticmaalka saliidda iyo qashinka ka soo baxa hawlgalkeeda. Waxa kale oo loo ogol yahay in la isticmaalo saliid synthetic ah oo leh viscosity of 5W50. Soosaarayaasha, Liquid Molly (10W60) iyo Mobile (10W50) ayaa mararka qaarkood lagula talinayaa.
