Injini ye-Nissan RB20E
Injini ye-Nissan RB20E yethulwa ngo-1984 futhi yakhiqizwa kwaze kwaba ngu-2002. Lena injini encane kunazo zonke ochungechungeni lwe-RB oludumile. Kukholakala ukuthi ithatha indawo ye-L20 endala.
Kuyi-RB20E okuyinguqulo yokuqala kuwo wonke umugqa. Wathola amasilinda ayisithupha ahlelwe ngokulandelana ebhodini lensimbi, kanye ne-crankshaft ye-short-stroke.
Phezulu, umkhiqizi ubeka ikhanda le-aluminium eline-shaft eyodwa nama-valve amabili kusilinda. Kuye isizukulwane nokuguqulwa, amandla kwaba 115-130 hp.
Izici
Amapharamitha e-ICE ahambisana nethebula:
| Izici | Amapharamitha |
|---|---|
| Ivolumu eqondile | I-1.99 l |
| Amandla | I-115-130 HP |
| I-Torque | 167-181 ku-4400 rpm |
| Isilinda block | Insimbi |
| Isistimu yamandla | Umjovo |
| Wamasilinda | 6 |
| Ezama-valve | 2 isilinda (izingcezu eziyi-12) |
| I-Fuel | Uphethiloli AI-95 |
| Ukusetshenziswa okuhlanganisiwe | Amalitha angu-11 ngamakhilomitha ayi-100 |
| Ivolumu kawoyela wenjini | I-4.2 l |
| I-viscosity edingekayo | Kuya ngesizini nesimo senjini. 0W-30, 5W-30, 5W-40, 10W-30, 10W-40 |
| Ukushintsha uwoyela nge | 15000 km, kangcono - ngemva 7.5 ayizinkulungwane |
| Ukushiswa kwamafutha okungenzeka | 500 amagremu ngebanga lika-1000 km |
| Isisetshenziswa senjini | Amakhilomitha angaphezu kwezinkulungwane ezingama-400. |
Izici ezishiwo zihambisana nenguqulo yokuqala yenjini.
Izimoto ezinenjini ye-RB20E
Isikhungo samandla saqala ukufakwa emotweni ye-Nissan Skyline ngo-1985, okokugcina ukufakwa ku-Nissan Crew ngo-2002, nakuba imoto ngokwayo yakhiqizwa kuze kube ngu-2009 ngokusekelwe kwezinye izinjini.
Uhlu lwamamodeli anenjini ye-RB20E:
- Stegea - 1996-1998.
- I-Skyline - 1985-1998.
- Laurel - 1991-1997.
- Abasebenzi - 1993-2002.
- Cefiro - 1988-199
Lolu phiko lube khona ngempumelelo emakethe iminyaka eyi-18, okukhombisa ukwethembeka nokufunwa kwalo.
Ukuguqulwa
I-RB20E yasekuqaleni ayithakaseli. Lena injini yakudala engu-6-cylinder in-line esebenza ngendlela yakudala. Inguqulo yesibili yayibizwa ngokuthi RB20ET - kwaba injini turbocharged "yavuthela" 0.5 ibha.
Amandla enjini afinyelela ku-170 hp. Okusho ukuthi, inguqulo yasekuqaleni ithole ukwanda okukhulu kwamandla. Nokho, ezinye izinguquko nge turbocharger kwadingeka amandla 145 hp.
Ngo-1985, i-Nissan yethula i-RB20DE ICE, kamuva eyaba edume kakhulu kulayini. Okugqamayo kwayo yikhanda lesilinda elinama-valve angama-24 elinamakhoyili okuthungela ngamanye. Ezinye izinguquko zenzeke: uhlelo lokuthatha, i-crankshaft entsha, izinduku zokuxhuma, i-ECU. Lezi zinjini zifakwe kumamodeli we-Nissan Skyline R31 no-R32, i-Laurel ne-Cefiro, zingathuthukisa amandla afinyelela ku-165 hp. Lezi zinjini zakhiqizwa isikhathi eside futhi zanda.
Ngokwesiko, ukuguqulwa okuphumelele kakhulu kwe-Nissan kufakwe i-turbocharger engu-16V, enikeza ingcindezi ye-0.5 bar. Imodeli yayibizwa ngokuthi i-RB20DET, isilinganiso sokucindezela sancipha saba ngu-8.5, ama-nozzles ashintshiwe, izinduku zokuxhuma, ama-piston, i-cylinder head gasket yasetshenziswa. Amandla emoto ayengu-180-190 hp.
Bekukhona nenguqulo ye-RB20DET Silver top - lena i-RB20DET efanayo, kodwa ngohlelo lwe-ECCS. Amandla ayo afinyelela ku-215 hp. ngo-6400 rpm. Ngo-1993, le yunithi yayekwa, njengoba kwavela inguqulo 2.5-litre - RB25DE, okungase ukuthuthukisa amandla afanayo, kodwa ngaphandle turbocharger.
Ngo-2000, umkhiqizi washintsha kancane izinjini ze-RB20DE ukuze zivumelane nezici zayo emazingeni emvelo. Yile ndlela ukuguqulwa kwe-NEO ngokuqukethwe okuncishisiwe kwezinto eziyingozi ekukhishweni kwavela. Uthole i-crankshaft entsha, i-cylinder head ethuthukisiwe, i-ECU kanye nesistimu yokwamukela ukudla, kanti onjiniyela bakwazi nokukhipha iziphakamisi ezidonsa amanzi. Amandla enjini awashintshile kakhulu - i-155 hp efanayo. Le yunithi itholakala ku-Skyline R34, Laurel C35, Stegea C34.
Isevisi
Zonke izinguqulo zezinjini ze-RB25DE, ngaphandle kwe-NEO, azidingi ukulungiswa kwe-valve, njengoba zifakwe izinxephezelo ze-hydraulic. Baphinde bathola i-timing belt drive. Ibhande kufanele lishintshwe ngemva kwamakhilomitha ayizinkulungwane ezingu-80-100, kodwa uma ikhwela elisolisayo livela ngaphansi kwe-hood noma ijubane lintanta, kungase kudingeke ukushintshwa okuphuthumayo.
Lapho ibhande lesikhathi liphuka, ama-pistons agoba i-valve, ehambisana nokulungiswa okumba eqolo.
Uma kungenjalo, ukugcinwa kwenjini kwehlela ezinqubweni ezijwayelekile: ukushintsha uwoyela, izihlungi, kusetshenziswa uphethiloli wekhwalithi ephezulu. Ngokulungiswa okufanele, lezi zinjini zizohamba amakhilomitha angaphezu kwezinkulungwane ezingama-200 ngaphandle kokulungiswa okukhulu.
Izinkinga
Lonke uchungechunge lwe-RB, kuhlanganise nezinjini ze-RB25DE, luthembekile. Lezi zitshalo zikagesi azinawo umklamo ongathi sína nokubala okungalungile kwezobuchwepheshe okungaholela ekuhlukaneni kwebhulokhi noma ezinye izinkinga ezinkulu. Lezi zinjini zinenkinga ngamakhoyili okushisa - ziyafeyila, bese kuba yinjini. Kunconywa ukuthi zishintshwe ngemva kwamakhilomitha ayizinkulungwane eziyi-100. Futhi, lonke uchungechunge lwe-RB luyisiminzi, ngakho-ke ukwanda kwebanga legesi lapho ushayela edolobheni noma ngisho nasemgwaqweni omkhulu akufanele kumangaze umnikazi.
Ezinye izinkinga ngendlela yokuvuza kukawoyela noma imfucuza yawo ijwayelekile futhi iyisici sazo zonke izinjini ezivuthayo zangaphakathi. Ngokwengxenye enkulu, zihlotshaniswa nokuguga okungokwemvelo.
Ukuhlwaya
OMasters bathi kungenzeka ukuzuza amandla amaningi avela ku-RB20DE, kodwa lokhu kuwukuchitha isikhathi nemali. Kulula futhi kushibhile ukuthenga inkontileka ye-RB20DET nge-turbine, ezokuvumela ukuthi ukhuphule amandla ngokushesha.
Kodwa i-RB20DET isivele ithuthukiswe. Iqiniso liwukuthi ayisebenzisi i-turbocharger engcono kakhulu, okunzima ukuyishuna. Kodwa iyakwazi "ukuyifutha" ibe yi-0.8 bar, enikeza cishe i-270 hp. Ukuze wenze lokhu, ku-RB20DET ama-nozzles amasha (kusuka enjini ye-RB26DETT), amakhandlela, i-intercooler nezinye izakhi.
Kukhona inketho yokushintsha i-turbine ibe yi-TD06 20G, ezongeza amandla engeziwe - afinyelela ku-400 hp. Asikho isidingo sokuqhubekela phambili, njengoba kukhona i-RB25DET motor enamandla afanayo.
isiphetho
Injini ye-Nissan RB20E iyiyunithi enokwethenjelwa enomthombo omude, osekuphelelwe yisikhathi. Emigwaqweni yaseRussia, kusenezimoto ezinale njini ezihamba ngesivinini esingaguquki. Kodwa-ke, kunoma yikuphi, ngenxa yokuguga kwemvelo, insiza yabo iphela.
Izinsiza ezifanele zithengisa izinjini zenkontileka ye-RB20E ebiza ama-ruble ayizinkulungwane ezingama-30-40 (intengo yokugcina incike esimweni kanye nemayela). Ngemva kwamashumi eminyaka, lawa ma-motor asasebenza futhi ayathengiswa, okuqinisekisa ukwethembeka kwawo.
