Renault F4RT cav
Txheem
Thaum ntxov 2000s, Renault engineers raws li cov neeg paub zoo F4P tau tsim lub zog tshiab uas tau dhau los ntawm nws cov thawj coj hauv lub zog.
piav qhia
Lub cav F4RT thawj zaug ua rau nws tus kheej paub hauv 2001 hauv Le Bourget (Fabkis) ntawm lub tsheb huab cua qhia. Lub cev muaj zog ntau lawm txuas ntxiv mus txog xyoo 2016. Lub rooj sib txoos ntawm chav tsev tau ua nyob rau ntawm Cleon Plant, lub tuam txhab niam txiv ntawm Renault kev txhawj xeeb.
Lub cev muaj zog tau npaj rau kev teeb tsa ntawm cov tsheb ntawm nws tus kheej tsim nyob rau hauv cov khoom siv sab saum toj kawg nkaus thiab kev ua kis las.
F4RT yog 2,0-liter turbocharged plaub-lub tog raj kheej roj av chav tsev nrog lub peev xwm ntawm 170-250 hp. s thiab torque 250-300 Nm.
Nruab rau ntawm Renault tsheb:
- Tuaj txog (2001-2003);
- Lossis txaus (2002-2009);
- Chaw (2002-2013);
- Lagoon (2003-2013);
- Megane (2004-2016);
- Scenic (2004-2006).
Ntxiv rau cov qauv uas tau teev tseg, lub tsheb F4RT tau teeb tsa ntawm Megane RS, tab sis twb nyob rau hauv ib qho yuam kev (270 hp thiab lub zog ntawm 340-360 Nm).
Lub tog raj kheej thaiv yog cam khwb cia hlau, tsis lined. Aluminium alloy lub tog raj kheej taub hau nrog 16 li qub thiab ob lub camshafts (DOHC). Nws yuav tsum raug sau tseg tias ob lub camshafts thiab lwm qhov ntawm CPG (piston, txuas rods, crankshaft) tau ntxiv dag zog.
Cov theem regulator ntawm lub internal combustion engine twb ploj mus. Lub sijhawm tsav tseem nyob, zoo li nws cov thawj, siv.
Kev teeb tsa ntawm lub turbine yuav tsum tau siv cov roj zoo dua, nrog kev ntsuas octane siab dua (AI-95 rau lub hauv paus qauv, AI-98 rau cov qauv kev ua si - Megane RS).
Hydraulic compensators tshem tawm qhov xav tau manually kho lub valve clearance.

Qhov kev hloov kho F4RT 774, 776 txhais li cas
Thaum lub sijhawm tsim khoom, lub cav tau rov ua dua tshiab. Lub hauv paus ntawm lub cev muaj zog tseem zoo li qub, cov kev hloov pauv feem ntau cuam tshuam cov ntawv txuas. Yog li, piv txwv li, F4RT 774 muaj ob lub turbo.
Kev hloov kho lub cev muaj zog muaj qhov sib txawv tseem ceeb hauv cov yam ntxwv.

Kev ntseeg tau, tsis muaj zog, kev ruaj ntseg
Kev ntseeg tau
Cov tswv tsheb hu rau F4RT cav txhim khu kev qha thiab ruaj khov. Qhov no muaj tseeb. Chav tsev nyob rau hauv nqe lus nug occupies ib tug nruab nrab txoj hauj lwm nyob rau hauv lub segment ntawm roj av turbo engine nyob rau hauv nws cov chav kawm ntawv.
Tus tsav tsheb los ntawm lub nroog Serov, hauv kev tshuaj xyuas ntawm nws Renault Megane, sau: "... Lub cav f4rt 874 tsim los ntawm Renault Sport. Muaj kev ntseeg siab heev, yooj yim thiab lub sijhawm sim ". Nws tau txais kev txhawb siab los ntawm ib tug npoj yaig los ntawm Omsk: “... Lub cav yeej nyiam nws qhov tsis muaj suab nrov thiab elasticity. Lub cav ntawm Renault-Nissan kev txhawj xeeb, tib yam yog muab tso rau hauv Nissan Sentra tshiab, tsuas yog cov roj txhaj tshuaj sib txawv thiab cov khoom noj khoom haus zoo li txawv ib yam nkaus.. Summing up MaFia57 los ntawm Orel: “... Kuv tau ua haujlwm lub cav F4RT tau 8 xyoo tam sim no. 245000 130 km. Rau tag nrho lub sijhawm ntawm kev ua haujlwm, kuv tsuas yog hloov lub turbine, thiab tom qab ntawd kuv tau rhuav tshem ntawm kuv tus kheej txoj kev ruam. Kuv yuav ib qho siv nrog ib mais ntawm XNUMX thiab kuv tseem tsav tsheb yam tsis muaj teeb meem ".
Nws yuav tsum tau borne nyob rau hauv lub siab hais tias qhov kev cia siab ntawm lub engine yog khaws cia tsuas yog raws sij hawm thiab tu kom zoo.
Thaum lub sijhawm ua haujlwm, nws tseem yuav tsum ua raws li tag nrho cov lus pom zoo ntawm cov chaw tsim khoom. Tsis quav ntsej lawv ua rau muaj kev cuam tshuam tsis zoo. Piv txwv li, kev siv AI-92 roj av, nrog rau cov roj qib qis, yog qhov tsis tsim nyog. Kev ua txhaum ntawm qhov kev pom zoo no yuav txo tau lub neej ntawm lub cev muaj zog thiab ua rau nws rov kho dua.
Lub cev tsis muaj zog
Qhov tsis zoo yog muaj nyob rau hauv txhua lub cav. Ib qho ntawm qhov tsis muaj zog tseem ceeb ntawm F4RT ib txwm muaj yog hluav taws xob tsis ua haujlwm. Ignition coils thiab qee qhov sensors (crankshaft txoj hauj lwm, lambda sojntsuam) feem ntau tsis ua haujlwm. Kev npaj txhij txog, ECU tuaj yeem xa cov teeb meem.
Cov peev txheej ntawm lub turbine kuj tawm ntau yam xav tau. Feem ntau, tom qab 140-150 txhiab kilometers, lub turbocharger yuav tsum tau hloov.
Feem ntau lub cav muaj kev siv roj ntau ntxiv. Yog vim li cas rau qhov no tej zaum yuav malfunctions nyob rau hauv lub turbine, daig piston rings, valve qia seals. Tsis tas li ntawd, ntau yam smudges tuaj yeem cuam tshuam rau kev siv roj (los ntawm cov roj crankshaft, valve cover seals, turbocharger bypass valve).
Tsis ruaj tsis khov ceev kuj tsis ua rau kev zoo siab. Lawv cov tsos yog txuam nrog kev siv cov roj tsis zoo, uas ua rau muaj kev cuam tshuam zoo tib yam ntawm lub throttle lossis injectors.
Txij nkawm zoo
Kev kho ntawm chav tsev tsis ua rau muaj teeb meem loj. Lub cam khwb cia hlau thaiv tso cai rau koj los tho qhov cylinders mus rau qhov loj me. Qhov no qhia tau hais tias muaj peev xwm ntawm tag nrho cov overhaul ntawm tag nrho cov internal combustion engine.
Cov khoom seem tsim nyog tuaj yeem yuav ntawm txhua lub khw tshwj xeeb. Qhov tsuas caveat yog tias tsuas yog thawj qhov chaw thiab cov rooj sib txoos tsim nyog siv rau hauv kev tsim kho lub cav. Qhov tseeb yog tias analogues tsis ib txwm sib haum mus rau qhov zoo, tshwj xeeb tshaj yog cov Suav. Nws tsis pom zoo kom siv cov khoom seem rau kev kho, vim nws yuav luag tsis tuaj yeem txiav txim siab lawv cov kev pabcuam seem.
Muab tus nqi siab ntawm cov khoom seem thiab qhov nyuaj ntawm kev ua haujlwm, nws yog ib qho tsim nyog los ntsuas qhov kev xaiv ntawm kev yuav lub cav cog lus. Nws tus nqi nruab nrab yog hais txog 70 txhiab rubles.
Lub cav F4RT, tsim los ntawm Renault engine builders, ua tau raws li tag nrho cov kev xav tau ntawm cov neeg tsav tsheb. Cov txiaj ntsig tseem ceeb yog kev ntseeg siab thiab kav ntev. Tab sis lawv tsuas yog tshwm sim yog tias cov chaw tsim khoom cov lus pom zoo rau kev pabcuam lub tsev tau ua raws.
