Injini yeRenault J8S
Okuqukethwe
Ngasekupheleni kweminyaka yama-70s, uchungechunge lwenjini yesiFulentshi J lwagcwaliswa ngenjini yedizili, eyasetshenziswa ngempumelelo ezimotweni eziningi ezidumile zakwaRenault.
Incazelo
Inguqulo ye-diesel yomndeni we-J J8S yamayunithi kagesi yathuthukiswa futhi yafakwa ekukhiqizeni ngo-1979. Ukukhishwa kuhlelwe embonini yenkampani eDouvrin (eFrance). Ikhiqizwe kokubili ku-aspirated (1979-1992) kanye ne-turbodiesel (1982-1996) izinguqulo.
I-J8S ingu-2,1 litre in-line injini kadizili eyi-four-cylinder enamandla angu-64-88 hp. nge-torque engu-125-180 Nm.
Kufakwe ezimotweni zakwaRenault:
- 18, 20, 21, 25, 30 (1979-1995);
- Master I (1980-1997);
- I-Traffic I (1980-1997);
- Umlilo I (1982-1986);
- Isikhala I, II (1982-1996);
- Safrane I (1993-1996).
Ukwengeza, le njini ingabonakala ngaphansi kwama-hood e-Cherokee XJ (1985-1994) kanye ne-Comanche MJ (1986-1987) SUVs.
I-cylinder block yenziwe nge-aluminium alloy, kodwa ama-liners ayinsimbi ensimbi. Lesi sixazululo sokuklama sikhulise kakhulu isilinganiso sokucindezela.
I-cylinder head nayo iyi-aluminium, ine-camshaft eyodwa nama-valve angu-8. Ikhanda lalinomklamo wangaphambi kwekamelo (Ricardo).
Ama-pistons enziwe ngokohlelo lwendabuko. Anamasongo amathathu, amabili awo yi-compress kanye ne-oil scraper eyodwa.
Idrayivu yesikhathi yohlobo lwebhande, ngaphandle kwezishintshi zesigaba kanye nezinxephezeli zehydraulic. Insiza yebhande incane kakhulu - izinkulungwane ezingama-60 km. Ingozi yekhefu (ukweqa) ilele ekugotshweni kwamavalvu.
Uhlelo lokuthambisa lusebenzisa iphampu kawoyela yohlobo lwegiya. Isixazululo esisha siwukuba khona kwamabhomu kawoyela akhethekile okupholisa phansi kwamapiston.
Iphampu yomjovo ethembekile yohlobo lwe-VE (Bosch) isetshenziswa ohlelweni lokuhlinzeka ngophethiloli.

Kusho ukuthini ukuguqulwa?
Ngokusekelwe ku-J8S, izinguquko ezimbalwa zenziwe. Umehluko omkhulu kumodeli yesisekelo kwaba ukwanda kwamandla ngenxa yokufakwa kwe-turbocharger.
Ngaphezu kwezici zamandla, ukunakwa okukhulu kukhokhwe ohlelweni lokuhlanza igesi ephumayo, ngenxa yalokho izinga lezindinganiso zokukhishwa kwemvelo liphakanyiswe kakhulu.
Izinguquko ekwakhiweni kwenjini yomlilo yangaphakathi akwenziwanga, ngaphandle kwezakhi zokubopha injini emzimbeni wemoto, kuye ngemodeli yayo.
Imininingwane eyengeziwe mayelana nezici zokulungiswa kwe-J8S kukhonjisiwe kuthebula:

Ukuthembeka
I-Diesel J8S ayihlukanga ekuthembekeni okuphezulu. Zonke izinguqulo ngaphambi kuka-1995 zazibuthakathaka kakhulu kulokhu.
Kusukela engxenyeni yomshini, ikhanda lesilinda libonakale liyinkinga. Igalelo labo lenziwa yimpilo ephansi yesevisi yebhande lesikhathi, ubunkimbinkimbi bezinye izikhundla lapho kulungiswa injini, kanye nokuntuleka kwezinto eziphakamisa ama-hydraulic.
Ngesikhathi esifanayo, ngokusho kokubuyekezwa kwabanikazi abaningi bezimoto, injini inakekela kalula ngaphezu kwezinkulungwane ezingu-500 km ngaphandle kokuphazamiseka okuphawulekayo. Ukuze wenze lokhu, kuyadingeka ukwenza ukugcinwa okuhleliwe ngesikhathi futhi ngokugcwele usebenzisa izingxenye eziphezulu (zangempela) nezinto ezisetshenziswayo. Ngesikhathi esifanayo, kunconywa ukunciphisa imigomo yesondlo.
Izindawo ezibuthakathaka
Kulolu daba, kuqala kunikezwa inhloko yesilinda. Ngokuvamile, ngamakhilomitha ayizinkulungwane ezingu-200 wokugijima, imifantu ivela ekamelweni langaphambili le-cylinder yesithathu. Ama-jeep ikakhulukazi angenwa yilesi simo.
Ngo-1995, umenzi wakhipha I-Technical Note 2825A, ukubambelela ngokuqinile kukho okwanciphisa ingozi yokuqhekeka kwekhanda.
Uma isetshenziswe ngendlela engalungile, ngokhahlo nangobudlova, injini evuthayo yangaphakathi ijwayele ukushisa ngokweqile. Imiphumela mibi - ukulungiswa okukhulu noma ukushintshwa kwemoto.
Injini yomlilo yangaphakathi ayinazo izindlela zokudambisa amandla e-inertial ye-oda lesibili. Ngenxa yalokho, injini igijima ngokudlidliza okunamandla. Imiphumela iwukuba buthakathaka kwamalunga ama-node nama-gaskets awo, ukubonakala kwamafutha nokuvuza okupholile.
Akuvamile ukuthi i-turbine iqale ukushayela uwoyela. Lokhu ngokuvamile kwenzeka 100 ayizinkulungwane km ukusebenza kwayo.
Ngakho, injini idinga ukunakwa njalo futhi eduze. Ngokutholwa ngesikhathi kanye nokuqedwa kwamaphutha, ukwethembeka nempilo yesevisi yenjini evuthayo yangaphakathi iyakhula.
Ukulondolozeka
Ukugcinwa kweyunithi kuyagculisa. Njengoba wazi, amabhlogo we-aluminium cylinder awakwazi ukukhandwa nhlobo. Kodwa ukuba khona kwemikhono ye-cast-iron kuzo kubonisa ukuthi kungenzeka ukuguqulwa okuphelele.
Ukuthola izingxenye nemihlangano emikhulu ukuze kubuyiselwe nakho kubangela izinkinga ezithile. Lapha, iqiniso lokuthi izingxenye eziningi eziyisipele zihlangene liyasiza, okungukuthi, zingathathwa ekulungisweni okuhlukahlukene kwe-J8S. Inkinga nje inani labo.
Lapho unquma ukubuyisela, kufanele ucabangele ithuba lokuthola injini yenkontileka. Ngokuvamile le nketho izoba eshibhile kakhulu.
Ngokuvamile, injini ye-J8S ayizange iphumelele kakhulu. Kodwa naphezu kwalokhu, ngokusebenza okufanele kanye nokugcinwa okufika ngesikhathi, okusezingeni eliphezulu, kwabonakala kuqinile, okuqinisekiswa ukuphila kwayo kwe-mileage ephezulu.
