Renault L7X cav
Txheem
Txhawm rau hloov PRV lub cav tsis tu ncua, cov neeg tsim hluav taws xob Fab Kis tau tshaj tawm ESL tshiab. Thawj tus yug hauv tsev neeg no yog lub zog L7X.
piav qhia
Lub cav tau tsim los ntawm Renault engineers ua ke nrog Peugeot-Citroen cov kws tshaj lij hauv xyoo 1997. Kev tsim khoom tau nqa tawm ntawm cov nroj tsuag hauv Douvrin (Fabkis).
L7X yog 3,0-liter V-twin petrol engine uas ua tau 190 hp. nrog thiab lub zog ntawm 267 Nm.
Nws tau nruab rau ntawm Renault Safrane, Laguna, Espace thiab "them" Clio V6 tsheb. Nyob rau hauv qhov Performance index ES9J4, nws tuaj yeem pom nyob rau hauv lub hood ntawm Peugeot (406, 407, 607 thiab 807), thiab nyob rau hauv qhov ntsuas XFX / XFV ntawm Sitroen XM thiab Xantia.
Lub tog raj kheej thaiv thiab lub tog raj kheej lub taub hau yog ua los ntawm aluminium alloy. Cam khwb cia hlau tes tsho.
Lub tog raj kheej taub hau muaj ob lub camshafts thiab 12 li qub. Cov shafts tau txais cov khoom nruab nrog theem hloov pauv txij li xyoo 2000.
Lub sij hawm siv lub sij hawm tsav nrog ib tug neeg kho tshuab tensioner roller (txog 2000 nws yog hydraulic). Cov peev txheej yog 120 txhiab km, tab sis nws yog qhov zoo dua los hloov nws ua ntej.
Ib qho tshwj xeeb hauv qhov txias txias yog lub twj tso kua mis. Ua ntej equipping lub cev muaj zog nrog ib theem shifter, ob hom twj tso kua dej tau siv, txawv nyob rau hauv lub diameters ntawm lub mounting qhov (73 thiab 63 mm).
Lub cav txhawb nqa tau nruab rau ntawm Clio V6 (saib cov lus). Ua ntej restyling, nws lub zog yog 230 hp. s, nyob rau hauv lub post-styling version - 255.

Kev hloov kho txhais li cas?
Nyob rau tib lub sijhawm ntawm kev tsim khoom, lub cav tau rov ua dua tshiab. Cov kev hloov pauv tau cuam tshuam cov ntawv txuas thiab lawv cov fastening. Mechanical feem tseem tsis hloov. Qhov tshwj xeeb yog Clio V6 thiab Venturi 300 Atlantique, uas muaj turbocharged xyaw.
Tau txais kev hloov pauv high-voltage coils. Lub triple (feem ntau) coil tau hloov nrog tus kheej coils.
Lub cav mounts tau hloov pauv raws li cov qauv ntawm lub tsheb uas lawv tau teeb tsa.
Specifications tau xyaum ua tib yam.

Kev ntseeg tau, tsis muaj zog, kev ruaj ntseg
Kev ntseeg tau
Raws li cov kws tshaj lij kev pabcuam tsheb thiab kev tshuaj xyuas ntawm cov tswv tsheb, lub cev muaj zog yog txhim khu kev qha thiab unpretentious. Peb yuav tsum them tribute, thaum xub thawj ntau muaj teeb meem nrog lub sij hawm. Tab sis qhov no tsis yog kev tsim kho tsis raug, tab sis qhov tsis paub txog theem pib ntawm cov yam ntxwv ntawm L7X.
Raws li kev saib xyuas cov cai thiab ua kom tiav ntawm cov chaw tsim khoom cov cai, lub cav zoo heev overlaps cov peev txheej hauv nws.
Lub cev tsis muaj zog
Tsis muaj cov ntsiab lus tsis muaj zog ruaj khov hauv chav tsev. Muaj cov teeb meem ntawm hluav taws xob tsis ua hauj lwm vim oxidized tiv tauj thiab ib qho kev poob qis ntawm cov chips los ntawm cov connectors.
Lub sij hawm siv yuav tsum tau saib xyuas tshwj xeeb. Ib qho kev nce hauv nws lub neej kev pabcuam cuam tshuam rau kev tawg, thiab, vim li ntawd, ib qho kev hloov kho loj lossis hloov lub cav.
Lub cav tsis tuaj yeem sawv ntsug txawm tias lub sijhawm luv luv overheating. Lub tog raj kheej thaiv, lub tog raj kheej taub hau thiab on-board computer ua tsis tau. Kev saib xyuas tas li ntawm kev ua haujlwm ntawm qhov ntsuas kub, ntsuas kub thiab ntsuas theem pib ntawm cov khoom siv thaum lub sijhawm mus txawv tebchaws yuav tshem tawm qhov muaj peev xwm ntawm overheating.
Txij nkawm zoo
Lub cev muaj zog yog suav tias yog kho tau. Kev tsis ntseeg hauv qhov teeb meem no yog tshwm sim los ntawm ib qho txhuas lub tog raj kheej thaiv. Nrog kev puas tsuaj sab hauv, nws tsis tuaj yeem kho.
Tsis muaj teeb meem nrog cov khoom seem hauv cov khw tshwj xeeb. Tab sis cov nqi rau qee qhov ntawm lawv qee zaum kuj siab heev. Piv txwv li, ib lub sij hawm siv sij hawm raug nqi ntawm $300 thiab $500. Nws hloov kuj tsis pheej yig. Ntawm qee lub tsheb qauv, lub cav yuav tsum raug tshem tawm los hloov nws.
Yog li ntawd, ua ntej pib kho, koj yuav tsum ua tib zoo txheeb xyuas cov nqi tsim nyog. Tej zaum nws yuav tshwm sim tias qhov kev xaiv ntawm kev yuav ib lub cav cog lus (tus nqi nruab nrab ntawm 60 txhiab rubles) yuav dhau los ua qhov zoo tshaj plaws.
Tus tub hlob ntawm ESL L7X series tau dhau los ua tiav thiab txhim khu kev qha. Tab sis ua raws thiab ua raws li tag nrho cov lus pom zoo ntawm cov chaw tsim khoom rau nws cov txij nkawm thiab kev ua haujlwm.
