Renault J8S cav
Txheem
Nyob rau hauv lub lig 70s, lub Fabkis J engine series tau ntxiv nrog ib tug diesel cav, uas tau ntse siv nyob rau hauv ntau nrov Renault tsheb.
piav qhia
Lub diesel version ntawm J J8S tsev neeg ntawm lub hwj chim units tau tsim thiab muab tso rau hauv ntau lawm nyob rau hauv 1979. Qhov kev tso tawm yog npaj ntawm lub tuam txhab cog hauv Douvrin (Fabkis). Nws tau tsim ob qho tib si hauv aspirated (1979-1992) thiab turbodiesel (1982-1996) versions.
J8S yog 2,1-liter nyob rau hauv-kab plaub-lub tog raj kheej diesel cav nrog lub peev xwm ntawm 64-88 hp. nrog thiab torque 125-180 Nm.
Nruab rau ntawm Renault tsheb:
- 18, 20, 21, 25, 30 (1979-1995);
- Master I (1980-1997);
- Traffic I (1980-1997);
- Hluav Taws Kuv (1982-1986);
- Chaw I, II (1982-1996);
- Safrane kuv (1993-1996).
Tsis tas li ntawd, lub cav no tuaj yeem pom hauv qab hoods ntawm Cherokee XJ (1985-1994) thiab Comanche MJ (1986-1987) SUVs.
Lub tog raj kheej thaiv yog ua los ntawm aluminium alloy, tab sis cov liners yog cam khwb cia hlau. Qhov kev daws teeb meem no tau nce qhov sib piv ntawm compression ntau.
Lub tog raj kheej taub hau kuj yog txhuas, nrog ib lub camshaft thiab 8 li qub. Lub taub hau muaj lub pre-chamber tsim (Ricardo).
Cov pistons yog ua raws li cov txheej txheem ib txwm muaj. Lawv muaj peb lub nplhaib, ob qho yog compression thiab ib qho roj scraper.
Siv lub sij hawm tsav tsheb, tsis muaj theem hloov pauv thiab hydraulic compensators. Txoj siv txoj siv yog me me - 60 txhiab km. Qhov txaus ntshai ntawm kev so (dhia) yog nyob rau hauv qhov khoov ntawm lub li qub.
Lub lubrication system siv lub iav hom roj twj tso kua mis. Txoj kev daws teeb meem yog qhov muaj cov roj tshwj xeeb nozzles kom txias hauv qab ntawm pistons.
Lub twj tso kua mis txhaj tshuaj txhim khu kev qha ntawm VE hom (Bosch) yog siv rau hauv cov khoom siv roj.

Kev hloov kho txhais li cas?
Raws li J8S, ntau qhov kev hloov kho tau tsim. Qhov sib txawv tseem ceeb ntawm lub hauv paus qauv yog qhov nce hauv lub zog vim kev teeb tsa ntawm lub turbocharger.
Ntxiv nrog rau cov yam ntxwv ntawm lub zog, kev saib xyuas ntau tau them rau cov pa purification system, vim tias qhov ntsuas ntawm ib puag ncig emission qauv tau nce siab.
Kev hloov pauv hauv kev tsim lub tshuab hluav taws xob sab hauv tsis tau ua tiav, tshwj tsis yog cov ntsiab lus ntawm fastening lub cev muaj zog rau lub cev lub cev, nyob ntawm nws cov qauv.

Kev ntseeg tau
Diesel J8S tsis txawv ntawm kev ntseeg siab. Tag nrho cov versions ua ntej 1995 yog tshwj xeeb tshaj yog tsis muaj zog nyob rau hauv no hais txog.
Los ntawm cov neeg kho tshuab ib feem, lub tog raj kheej lub taub hau tig los ua teeb meem. Lawv qhov kev pab cuam yog tsim los ntawm kev ua haujlwm qis ntawm lub sijhawm siv, qhov nyuaj ntawm qee txoj haujlwm thaum kho lub cev muaj zog, thiab tsis muaj hydraulic lifters.
Nyob rau tib lub sijhawm, raws li kev tshuaj xyuas ntawm ntau tus tswv tsheb, lub cav tau yooj yim saib xyuas ntau dua 500 txhiab km yam tsis muaj kev puas tsuaj loj. Txhawm rau ua qhov no, nws yog ib qho tsim nyog yuav tsum ua raws li kev saib xyuas raws sijhawm thiab siv tag nrho cov khoom zoo (thawj) thiab cov khoom siv. Tib lub sijhawm, nws raug pom zoo kom txo cov nqe lus ntawm kev saib xyuas.
Lub cev tsis muaj zog
Hauv qhov no, qhov tseem ceeb yog muab rau lub tog raj kheej taub hau. Feem ntau, los ntawm 200 txhiab km ntawm kev khiav, cov kab nrib pleb tshwm nyob rau hauv lub prechamber ntawm peb lub tog raj kheej. Jeeps tshwj xeeb tshaj yog raug rau qhov tshwm sim no.
Xyoo 1995, cov chaw tsim khoom tau tshaj tawm Cov Lus Ceeb Toom 2825A, kev coj ua nruj me ntsis uas txo qhov kev pheej hmoo ntawm lub taub hau tawg.
Nrog kev ua haujlwm tsis raug, hnyav thiab hnyav, lub tshuab hluav taws xob sab hauv yog ua rau overheating. Cov kev tshwm sim yog deplorable - ib tug loj overhaul los yog hloov lub cev muaj zog.
Internal combustion engine tsis muaj mechanisms rau damping thib ob-order inertial rog. Yog li ntawd, lub cev muaj zog khiav nrog kev vibrations muaj zog. Qhov tshwm sim yog qhov tsis muaj zog ntawm cov pob qij txha ntawm cov pob qij txha thiab lawv cov gaskets, cov tsos ntawm cov roj thiab cov dej xau.
Nws tsis yog qhov nyuaj rau lub turbine pib tsav roj. Feem ntau qhov no tshwm sim rau 100 txhiab km ntawm nws txoj haujlwm.
Yog li, lub cav yuav tsum tau ua tib zoo saib xyuas tas li. Nrog rau kev tshawb pom raws sij hawm thiab tshem tawm cov kev ua yuam kev, kev ntseeg siab thiab kev pabcuam lub neej ntawm lub cav combustion yog nce.
Txij nkawm zoo
Kev ruaj ntseg ntawm chav tsev yog txaus siab. Raws li koj paub, aluminium cylinder blocks tsis tuaj yeem kho txhua. Tab sis lub xub ntiag ntawm cam khwb cia hlau tes tsho nyob rau hauv lawv qhia tau hais tias muaj peev xwm ntawm ib tug tag nrho overhaul.
Nrhiav qhov chaw thiab cov rooj sib txoos rau kev kho dua tshiab kuj ua rau qee qhov teeb meem. Ntawm no, qhov tseeb tias feem ntau ntawm cov khoom seem sib koom ua ke los cawm, uas yog, lawv tuaj yeem khaws los ntawm ntau yam kev hloov kho ntawm J8S. Qhov teeb meem nkaus xwb yog lawv tus nqi.
Thaum txiav txim siab txog kev kho dua tshiab, koj yuav tsum xav txog qhov muaj peev xwm tau txais lub cav cog lus. Feem ntau qhov kev xaiv no yuav pheej yig dua.
Feem ntau, lub cav J8S tau hloov mus ua tsis tau zoo heev. Tab sis txawm hais tias qhov no, nrog rau kev ua haujlwm kom raug thiab kev pabcuam zoo raws sijhawm, nws tau dhau los ua hardy, raws li pov thawj los ntawm nws cov mileage siab.
