Mathoasong a lilemo tsa bo-2000, baenjiniere ba Renault ba ipapisitseng le F4P e tsebahalang ba ile ba theha yuniti e ncha ea matla e fetang ea pele ho matla.

Enjene ea F4RT e ile ea qala ho tsebahala ka 2001 Le Bourget (Fora) papaling ea moea ea likoloi. Tlhahiso ea likoloi e ile ea tsoela pele ho fihlela 2016. Kopano ea yuniti e ile ea etsoa Cleon Plant, k'hamphani ea motsoali ea Renault concern.
Enjene e ne e reretsoe ho kenngoa likoloing tsa tlhahiso ea eona ka holimo-limo le lisebelisoa tsa lipapali.
F4RT ke 2,0-litre turbocharged four-cylinder peterole unit ea matla a matla a 170-250 hp. s le torque 250-300 Nm.
E kentsoe likoloing tsa Renault:
- Tloo (2001-2003);
- Kapa ho lekane (2002-2009);
- Sebaka (2002-2013);
- Lagoon (2003-2013);
- Megane (2004-2016);
- Scenic (2004-2006).
Ho phaella ho mehlala e thathamisitsoeng, koloi ea F4RT e kentsoe Megane RS, empa e se e ntse e le ka mokhoa o qobelloang (270 hp le torque ea 340-360 Nm).
The cylinder block ke tšepe e entsoeng ka tšepe, eseng mola. Aluminium alloy cylinder hlooho e nang le li-valve tse 16 le li-camshaft tse peli (DOHC). Hoa lokela ho hlokomeloa hore li-camshaft le likarolo tse ling tsa CPG (pistons, lithupa tse kopanyang, crankshaft) li matlafatsoa.
Molaoli oa mohato oa mochine o tukang ka hare o ne o felile. Ho khanna nako ho ile ha sala, joalo ka pele ho eona, lebanta.
Ho kenngoa ha turbine ho ne ho hloka tšebeliso ea mafura a boleng bo phahameng, ka tekanyo e phahameng ea octane (AI-95 bakeng sa mohlala oa motheo, AI-98 bakeng sa mohlala oa lipapali - Megane RS).
Li-compensator tsa Hydraulic li felisa tlhokahalo ea ho fetola tumello ea valve ka letsoho.

Ho tšepahala, mefokolo, ho boloka
Ho tšepahala
Beng ba likoloi ba bitsa enjene ea F4RT e ka tšeptjoa ebile e tšoarella. Ke 'nete. Yuniti eo ho buuoang ka eona e maemong a mahareng karolong ea enjine ea peterole ea turbo sehlopheng sa eona.
Mokhanni oa koloi ea tsoang motseng oa Serov, ha a hlahloba Renault Megane ea hae, oa ngola: “... Enjene ea f4rt 874 e ntlafalitsoeng ke Renault Sport. E tšepahalang haholo, e bonolo ebile e lekoa ka nako ”. O tšehetsoa ka botlalo ke mosebetsi-'moho le Omsk: “... Enjene e hlile e rata ho hloka lerata le ho reketla ha eona. Enjene ea Renault-Nissan e amehile, e tšoanang e behiloe ho Nissan Sentra e ncha, ke sistimi ea ente ea peterole feela e fapaneng mme mefuta e mengata ea ho kenya e bonahala e fapane le eona.. Ho akaretsa MaFia57 ho tsoa ho Orel: “... Ke qetile lilemo tse 4 ke ntse ke sebelisa enjene ea F8RT. Mileage 245000 km.

E tlameha ho hopoloa hore ho tšepahala ha enjene ho bolokoa feela ka tlhokomelo e nakong le e nepahetseng.
Nakong ea ts'ebetso, ho boetse hoa hlokahala ho latela litlhahiso tsohle tsa moetsi. Ho li hlokomoloha ho lebisa liphellong tse ke keng tsa etsolloa. Ka mohlala, tšebeliso ea peterole ea AI-92, hammoho le oli ea boemo bo tlaase, ha e amohelehe. Tlolo ea khothaletso ena e tla fokotsa haholo bophelo ba enjene mme e lebise ntlafatsong ea eona.

Mathata a teng ka har'a enjene e 'ngoe le e 'ngoe. E 'ngoe ea mefokolo e ka sehloohong ea F4RT ka tloaelo e bile ho hlōleha ha motlakase. Likhoele tsa ho khantša le li-sensor tse ling (sebaka sa crankshaft, probe ea lambda) li hlōleha hangata. Ho sa lebelloa, ECU e ka tlisa mathata.
Mohloli oa turbine le ona o siea lintho tse ngata tse lakatsehang. Hangata, ka mor'a lik'hilomithara tse likete tse 140-150, turbocharger e tlameha ho fetoloa.
Hangata enjene e na le tšebeliso e eketsehileng ea oli. Lebaka la sena e ka 'na ea e-ba ho se sebetse hantle ho turbine, mehele ea piston e khomaretsoeng, li-valve stem seals. Ntle le moo, li-smudges tse fapaneng li ka ama ts'ebeliso ea oli (ka setiiso sa oli sa crankshaft, litiiso tsa sekoaelo sa valve, turbocharger bypass valve).
