Injini ye-Renault F4RT
Okuqukethwe
Ekuqaleni kwawo-2000, onjiniyela bakwaRenault abasekelwe ku-F4P eyaziwa kakhulu bakha iyunithi yamandla entsha eyedlula eyandulelayo emandleni.
Incazelo
Injini ye-F4RT yaqala ukwaziwa ngo-2001 e-Le Bourget (eFrance) embukisweni womoya wezimoto. Ukukhiqizwa kwezimoto kwaqhubeka kwaze kwaba ngu-2016. Ukuhlanganiswa kwalolu phiko kwenziwe eCleon Plant, okuyinkampani engumzali weRenault concern.
I-motor yayihloselwe ukufakwa ezimotweni zokukhiqiza kwayo endaweni ephezulu kanye nemishini yezemidlalo.
I-F4RT iyiyunithi yamandla kaphethiloli engu-2,0-litre turbocharged four-cylinder enamandla angu-170-250 hp. s kanye ne-torque engu-250-300 Nm.
Kufakwe ezimotweni zakwaRenault:
- Woza (2001-2003);
- Noma Kwanele (2002-2009);
- Isikhala (2002-2013);
- Laguna (2003-2013);
- Megane (2004-2016);
- I-Scenic (2004-2006).
Ngaphezu kwamamodeli afakwe ohlwini, imoto ye-F4RT ifakwe ku-Megane RS, kodwa kakade inguqulo ephoqelekile (270 hp kanye ne-torque engu-340-360 Nm).
I-cylinder block iyinsimbi ekhonjiwe, ayilayishiwe. Ikhanda le-aluminium alloy cylinder elinama-valve angu-16 nama-camshaft amabili (DOHC). Kumele kuqashelwe ukuthi kokubili ama-camshafts nezinye izingxenye ze-CPG (pistons, izinduku zokuxhuma, i-crankshaft) ziyaqiniswa.
Isilawuli sesigaba senjini evuthayo yangaphakathi sasingasekho. Idrayivu yesikhathi yahlala, njengaleyo eyandulelayo, ibhande.
Ukufakwa kwe-turbine kudinga ukusetshenziswa kukaphethiloli wekhwalithi ephezulu, enezinga eliphakeme le-octane (AI-95 yemodeli eyisisekelo, i-AI-98 yemodeli yezemidlalo - iMegane RS).
Izinxephezelo ze-Hydraulic ziqeda isidingo sokulungisa ngesandla imvume ye-valve.

Kusho ukuthini ukuguqulwa kwe-F4RT 774, 776
Phakathi nenqubo yokukhiqiza, injini yathuthukiswa ngokuphindaphindiwe. Isisekelo se-motor sahlala sinjalo, izinguquko zithinte kakhulu okunamathiselwe. Ngakho, isibonelo, i-F4RT 774 ine-turbo ephindwe kabili.
Ukuguqulwa kwezimoto kube nomehluko omkhulu ezicini zobuchwepheshe.

Ukuthembeka, ubuthakathaka, ukugcina
Ukuthembeka
Abanikazi bezimoto babiza injini ye-F4RT ukuthi ithembekile futhi iqinile. Yiqiniso lokhu. Iyunithi okukhulunywa ngayo ithatha indawo emaphakathi engxenyeni yezinjini ze-turbo kaphethiloli ekilasini layo.
Umshayeli wemoto ovela edolobheni laseSerov, ekubuyekezeni kwakhe i-Renault Megane, uyabhala: “... Injini ye-f4rt 874 eyakhiwe ngabakwaRenault Sport. Ithembekile kakhulu, ilula futhi ihlolwe isikhathi”. Usekelwa ngokugcwele uzakwabo wase-Omsk: “... Injini ithanda ngempela ukungabi namsindo nokunwebeka kwayo. Injini yeRenault-Nissan ifakwe okufanayo kwiNissan Sentra entsha, i-fuel injection system kuphela ehlukile futhi indlela ethathwa ngayo ibonakala ihlukile.. Ukufingqa i-MaFia57 evela ku-Orel: “... Sengineminyaka engu-4 ngisebenzisa injini ye-F8RT. I-Mileage 245000 km. Phakathi naso sonke isikhathi sokusebenza, ngashintsha i-turbine kuphela, futhi ngemva kwalokho ngayonakalisa ngobuwula bami. Ngithenge esetshenzisiwe enamakhilomitha angu-130 futhi ngisashayela ngaphandle kwezinkinga”.
Kumele kukhunjulwe ukuthi ukwethembeka kwenjini kugcinwa kuphela ngokulungiswa okufika ngesikhathi futhi okufanele.
Ngesikhathi sokusebenza, kuyadingeka futhi ukulandela zonke izincomo zomenzi. Ukungazinaki kuholela emiphumeleni engenakuhlehliswa. Isibonelo, ukusetshenziswa kwephethiloli ye-AI-92, kanye namafutha ebanga eliphansi, akwamukeleki. Ukwephulwa kwalesi sincomo kuzonciphisa kakhulu impilo yemoto futhi kuholele ekulungisweni kwayo.
Izindawo ezibuthakathaka
Ukungalungi kutholakala kuyo yonke injini. Obunye bobuthakathaka obuyinhloko be-F4RT ngokwesiko kwaba ukuhluleka kukagesi. Amakhoyili okuthungela nezinye izinzwa (indawo ye-crankshaft, i-lambda probe) ayahluleka kaningi. Ngokungalindelekile, i-ECU ingaletha izinkinga.
Insiza ye-turbine nayo ishiya okuningi okungafunwa. Ngokuvamile, ngemva amakhilomitha ayizinkulungwane 140-150, turbocharger kufanele kushintshwe.
Ngokuvamile injini ibhekana nokusetshenziswa okwengeziwe kukawoyela. Isizathu salokhu kungase kube ukungasebenzi kahle kwe-turbine, izindandatho ze-piston ezinamathele, izimpawu ze-valve stem. Ukwengeza, ama-smudges ahlukahlukene angathinta ukusetshenziswa kukawoyela (ngophawu lwamafutha e-crankshaft, ama-valve cover seal, i-turbocharger bypass valve).
Izivinini zokungenzi lutho ezingazinzile nazo azibangeli injabulo. Ukubukeka kwabo kuhlotshaniswa nokusetshenziswa kwephethiloli esezingeni eliphansi, okuholela ekuvaleni okuvamile kwe-throttle noma ama-injection.
Ukulondolozeka
Ukulungiswa kweyunithi akubangeli izinkinga ezinkulu. I-cast iron block ikuvumela ukuthi uthwale amasilinda ngosayizi odingekayo. Lokhu kubonisa ukuthi kungenzeka ukuthi kulungiswe kabusha yonke injini evuthayo yangaphakathi.
Izingxenye ezisele ezidingekayo zingathengwa kunoma yisiphi isitolo esikhethekile. Okuwukuphela kwe-caveat ukuthi izingxenye zangempela kuphela nezincane ezifanele ukusetshenziswa ekwakhiweni kabusha kwenjini. Iqiniso liwukuthi ama-analogue awahambisani nekhwalithi ngaso sonke isikhathi, ikakhulukazi amaShayina. Akunconywa ukusebenzisa izingxenye ezisele ezisetshenzisiwe ukuze zilungiswe, ngoba cishe akunakwenzeka ukunquma impilo yabo yesevisi esele.
Njengoba kunikezwe izindleko eziphezulu zezingxenye ezisele kanye nobunzima bomsebenzi, kuyadingeka ukuhlola inketho yokuthenga injini yenkontileka. Intengo yayo ejwayelekile imayelana nama-ruble ayizinkulungwane ezingama-70.
Injini ye-F4RT, eyakhiwe abakhi benjini yakwaRenault, ihlangabezana nazo zonke izidingo zabashayeli. Izinzuzo eziyinhloko ukwethembeka nokuqina. Kodwa zivela kuphela uma izincomo zomkhiqizi zokusevisa uphiko zilandelwa.
