Renault K4J cav
Txheem
Thaum kawg ntawm lub 90s, Renault engineers tswj los tsim ib lub cav uas tau los ua ib tug masterpiece ntawm Fabkis cav lub tsev. Lub zog tsim hluav taws xob tau siv dav hauv kev lag luam thoob ntiaj teb. Tus yuam sij rau kev vam meej yog qhov ua tau zoo thiab kav ntev ntawm cov khoom.
piav qhia
Lub cav K4J tau tsim thiab muab tso rau hauv kev tsim khoom hauv xyoo 1998. Tau txais kev lees paub thoob ntiaj teb hauv xyoo 1999 ntawm qhov pib ua yeeb yam hauv Geneva (Switzerland). Nws yog ib tug roj av nyob rau hauv-kab plaub-lub tog raj kheej aspirated engine nrog ib tug ntim ntawm 1,4 litres nrog ib tug muaj peev xwm ntawm 82-100 hp nrog ib tug torque ntawm 127 Nm. Ua kom txog rau thaum 2013, muaj ntau yam kev hloov kho.
Lub cav K4J thiab nws cov kev hloov kho tau nruab rau ntawm Renault tsheb:
- Clio (1999-2012);
- Cim (1999-2013);
- Scenic (1999-2003);
- Megane (1999-2009);
- Hom (2004-2008);
- Grand Modus (2004-2008).
Lub tog raj kheej thaiv yog ua los ntawm cov hlau nplaum.
Aluminium lub tog raj kheej taub hau. Lub taub hau muaj 16 li qub. Nyob rau sab sauv muaj ob lub camshafts ntawm rau rau kev txhawb nqa txhua.
Valve lifters ua kom yooj yim kho lub valve clearance.
Siv lub sijhawm tsav tsheb. Txoj siv yog tsim rau kev khiav ntawm 60 txhiab km. Lub twj tso kua mis (dej twj tso kua mis) tau txais kev sib hloov los ntawm nws.
Crankshaft hlau, forged. Nws nyob ntawm tsib qhov kev txhawb nqa (liners-bearings).
Pistons yog tus qauv, nrum aluminium alloy. Lawv muaj peb lub nplhaib, ob qho yog compression, ib qho yog roj scraper.
Kaw crankcase ventilation system.
Cov khoom siv roj muaj xws li cov hauv qab no:
- roj twj tso kua mis (nyob rau hauv lub t / tank);
- throttle sib dhos;
- lim zoo;
- roj tswj siab;
- nozzles;
- roj kab.
Cov ntsiab lus ntxiv yog cov pa roj recirculation system thiab lim cua.
Chain roj twj tso kua mis tsav. Nws tau txais kev sib hloov los ntawm crankshaft. Lub ntim ntawm cov roj nyob rau hauv lub system yog 4,85 litres.
Lub txim plugs muaj lawv tus kheej high voltage coils.

Kev ntseeg tau, tsis muaj zog, kev ruaj ntseg
Xav txog yam tseem ceeb uas yuav tsum tau ua ntxiv rau cov yam ntxwv ntawm txhua lub cav.
Kev ntseeg tau
K4J lub cev muaj zog muaj ntau cov txiaj ntsig zoo uas ua rau nws ua tau zoo. Feem coob ntawm cov tswv tsheb ntawm cov tsheb nrog xws li lub cav sau tseg nws qhov kev ntseeg siab.
Lub simplicity ntawm tus tsim thiab ib tug xov tooj ntawm tshiab technologies paub meej tias lub tswv yim ntawm feem ntau. Piv txwv li, lub rooj sab laj tus tswv cuab ZeBriD los ntawm Novosibirsk sau: "... Kuv tshawb xyuas cov roj tsuas yog lub caij ntuj sov, ntawm lub cav txias ... Thiab txhua yam zoo".
Lub cav yuav txhim khu kev qha thiab ruaj khov yog tias cov kev ua haujlwm tau pom zoo los ntawm cov chaw tsim khoom raug pom zoo. Cov kev cai tshwj xeeb yog muab tso rau ntawm qhov zoo ntawm cov kua dej, tshwj xeeb tshaj yog cov roj thiab roj. Ntawm no yog ib qho "tab sis" tshwm sim - yog tias koj tseem tuaj yeem yuav cov roj uas yuav tsum tau ua, ces cov khoom yuav phem dua nrog roj. Koj yuav tsum txaus siab rau yam koj muaj. Tsuas muaj ib txoj kev tawm xwb - koj yuav tsum nrhiav lub chaw nres tsheb roj av uas cov roj av ntau dua lossis tsawg dua tus qauv.
Hauv Is Taws Nem koj tuaj yeem nrhiav cov ntaub ntawv hais txog kev siv roj av AI-92. Nws tsis yog tseeb kiag li. Hom roj pom zoo yog AI-95.
Cov chaw tsim khoom qhia cov ntsiab lus tshwj xeeb rau kev hloov cov khoom siv. Ntawm no, cov lus pom zoo yuav tsum tau ua kom muaj tswv yim, suav nrog kev ua haujlwm ntawm lub cav. Nws yog qhov tseeb tias lawv txawv ntawm European. Thiab qhov zoo ntawm cov roj thiab lubricants, thiab cov xwm txheej ntawm txoj kev. Yog li ntawd, lub sijhawm hloov pauv rau cov khoom siv thiab cov khoom yuav tsum raug txo.
Nrog rau tus cwj pwm tsim nyog rau chav tsev, nws tuaj yeem ua haujlwm yam tsis muaj kev puas tsuaj rau lub sijhawm ntev, nrog kev sib tshooj tseem ceeb ntawm cov peev txheej cog lus.
Lub cev tsis muaj zog
Txawm tias muaj tseeb hais tias tus tsim ntawm lub cav tag nrho ua tau zoo, tsis muaj zog nyob rau hauv tej rooj plaub tshwm sim rau nws.
Ua ntej tshaj plaws, nws tau sau tseg Lub sij hawm siv tsis muaj zog. Qhov txaus ntshai ntawm nws breakage yog nyob rau hauv qhov khoov ntawm li qub. Xws li kev ntxhov siab ua rau muaj kev kho mob hnyav thiab ntau dua ntawm kev kho tag nrho lub cav. Txoj siv sia siv lub neej yog txiav txim siab los ntawm cov chaw tsim khoom ntawm 60 txhiab km ntawm lub tsheb khiav. Nyob rau hauv qhov tseeb, nws muaj peev xwm saib xyuas 90 txhiab km, tab sis kev hloov yuav tsum tau ua raws li cov neeg tsim khoom pom zoo. Ua ke nrog lub sij hawm siv, nws raug nquahu kom hloov txoj siv alternator.
Roj xau los ntawm ntau cov ntsaws ruaj ruaj kuj tsis tshua muaj. Txawm li cas los xij, daim duab no tsis yog tsuas yog rau Fab Kis lub zog xwb. Kev saib xyuas ntawm tus tswv lub tsheb yuav pab txhawm rau txheeb xyuas qhov ua haujlwm tsis zoo ntawm lub sijhawm, thiab nws yooj yim los kho koj tus kheej. Piv txwv li, nws yog txaus kom nruj lub valve npog mount thiab qhov teeb meem ntawm cov roj to yuav daws. Hauv qhov xwm txheej hnyav, koj tuaj yeem siv cov kev pabcuam ntawm cov kws pabcuam tsheb tshwj xeeb. Nws yog ib qho tsim nyog kom nco qab tias kev saib xyuas raws sij hawm tsis suav nrog qhov tshwm sim ntawm cov roj to.
Qhov tsis muaj zog loj tshaj plaws yog ua tsis tiav hauv kev ua haujlwm ntawm cov khoom hluav taws xob. Ignition coils thiab ntau yam sensors (crankshaft txoj hauj lwm sensor, siab sensor, thiab lwm yam) yog raug rau xws li ib tug "kev txom nyem". Nyob rau hauv cov ntaub ntawv no, nws yog tsis yooj yim sua kom tshem tawm cov malfunction yam tsis muaj tsheb tshwj xeeb kev pab cuam.
Zoo nkauj txwv kev pab cuam lub neej (100 txhiab km) muaj lub crankshaft damper pulley. Nws raug nquahu kom hloov nws tom qab qhov thib ob teem sijhawm hloov ntawm txoj siv sijhawm.
Yog li, peb pom tias muaj cov ntsiab lus tsis muaj zog ntawm lub cav, tab sis feem ntau tus tswv ntawm lub tsheb provokes lawv tshwm sim. Qhov tshwj xeeb yog auto electrics. Muaj tseeb muaj qhov tsis xws luag ntawm cov chaw tsim khoom ntawm no.
Txij nkawm zoo
Kev kho cav tsis yooj yim heev. Lub cam khwb cia-hlau thaiv tso cai rau koj los tho qhov cylinders mus rau qhov yuav tsum tau kho loj.
Kev hloov ntawm qhov chaw thiab cov rooj sib txoos tuaj yeem ua tau, tab sis nws tau sau tseg tias qee zaum muaj teeb meem nrog lawv txoj kev tshawb nrhiav. Tsis yog nyob rau hauv txhua lub nroog nyob rau hauv ib lub khw tshwj xeeb lawv nyob rau hauv txoj cai assortment. Ntawm no yog lub khw hauv online yuav los cawm, qhov twg koj tuaj yeem xaj cov khoom seem tsim nyog. Muaj tseeb, lub sijhawm ua haujlwm tuaj yeem ntev. Tsis tas li ntawd, ntau tus neeg tsav tsheb tau them nyiaj rau cov nqi siab ntawm cov khoom thiab cov khoom sib dhos.
Kev siv cov khoom seem los ntawm kev rhuav tshem tsis tas yuav ua rau qhov xav tau vim qhov tsis tuaj yeem kuaj xyuas lawv tus mob.
Raws li tau sau tseg, lub cav combustion sab hauv muaj ib qho yooj yim tsim. Tab sis qhov no tsis txhais hais tias txhua leej txhua tus muaj peev xwm kho nws nrog lawv tus kheej tes. Koj tsis tuaj yeem ua yam tsis muaj cov cuab yeej tshwj xeeb thiab khoom siv. Zoo li tsis muaj kev paub txog cov nuances ntawm kev kho. Piv txwv li, kev hloov ntawm ib qho gasket yuav tsum muaj qee qhov nruj torque ntawm nws cov fasteners. Nyob rau hauv rooj plaub uas tsis ua raws li cov lus pom zoo, qhov zoo tshaj plaws, yuav muaj cov kua dej ntws tawm, qhov phem tshaj plaws, cov xov ntawm cov txiv ntoo los yog stud yuav raug torn.
Qhov kev xaiv zoo tshaj plaws rau kev kho lub cev muaj zog yog tso siab rau cov kws tshaj lij ntawm kev pabcuam tsheb tshwj xeeb.
Fabkis txoj kev xav K4J tau ua tiav zoo heev, yooj yim hauv kev tsim, txhim khu kev qha thiab ruaj khov. Tab sis cov kev zoo no tsuas yog tshwm sim yog tias tag nrho cov chaw tsim khoom cov lus pom zoo tau pom thaum ua haujlwm ntawm lub cav.
