Renault J8S injini

Chakumapeto kwa zaka za m'ma 70s, mndandanda wa injini ya French J idawonjezeredwa ndi injini ya dizilo, yomwe idagwiritsidwa ntchito bwino pamagalimoto ambiri otchuka a Renault.

mafotokozedwe

Mtundu wa dizilo wa gulu lamagetsi la J J8S lamagetsi adapangidwa ndikupangidwa mu 1979. Kutulutsidwa kumakonzedwa pafakitale yamakampani ku Douvrin (France). Idapangidwa m'mitundu yonse ya aspirated (1979-1992) ndi turbodiesel (1982-1996).

J8S ndi injini ya dizilo ya 2,1-lita pamzere anayi yamphamvu yokhala ndi mphamvu ya 64-88 hp. ndi torque 125-180 Nm.

Zakhazikitsidwa pamagalimoto a Renault:

• 18, 20, 21, 25, 30 (1979-1995);
• Master I (1980-1997);
• Magalimoto I (1980-1997);
• Moto I (1982-1986);
• Space I, II (1982-1996);
• Safrane I (1993-1996).

Kuonjezera apo, injini iyi ikhoza kuwonedwa pansi pazitsulo za Cherokee XJ (1985-1994) ndi Comanche MJ (1986-1987) SUVs.

Chophimbacho chimapangidwa ndi aluminium alloy, koma zomangira zake ndi chitsulo choponyedwa. Njira yothetsera vutoli yawonjezera kwambiri chiwerengero cha kuponderezana.

Mutu wa silinda ndi aluminiyamu, wokhala ndi camshaft imodzi ndi ma valve 8. Mutuwo unali ndi pre-chamber design (Ricardo).

Ma pistoni amapangidwa motsatira dongosolo lachikhalidwe. Iwo ali ndi mphete zitatu, ziwiri zomwe ndi compression ndi mafuta scraper imodzi.

Magalimoto amtundu wa lamba, opanda zosinthira magawo ndi ma hydraulic compensators. Lamba gwero ndi laling'ono kwambiri - 60 zikwi Km. Kuopsa kwa kupuma (kudumpha) kwagona pakupindika kwa ma valve.

Dongosolo lopaka mafuta limagwiritsa ntchito pampu yamafuta amtundu wa gear. Yankho labwino kwambiri ndi kukhalapo kwa ma nozzles apadera amafuta oziziritsa pansi pa pistoni.

Pampu yodalirika ya jakisoni yamtundu wa VE (Bosch) imagwiritsidwa ntchito pamakina operekera mafuta.

*makhalidwe m'mabulaketi a turbodiesel. ** pali zosintha za injini yokhala ndi nthawi yayitali.

Kodi zosintha zimatanthauza chiyani?

Kutengera J8S, zosintha zingapo zidapangidwa. Kusiyanitsa kwakukulu kuchokera ku chitsanzo choyambira kunali kuwonjezeka kwa mphamvu chifukwa cha kuyika kwa turbocharger.

Kuphatikiza pa mawonekedwe amphamvu, chidwi chochuluka chidaperekedwa ku dongosolo loyeretsera mpweya wotulutsa mpweya, chifukwa chake kuchuluka kwa miyezo yotulutsa zachilengedwe kudakwezedwa kwambiri.

Kusintha kwa mapangidwe a injini yoyaka mkati sikunachitike, kupatulapo zinthu zomangirira galimoto ku thupi la galimoto, malingana ndi chitsanzo chake.

Kudalirika

Dizilo J8S samasiyana ndi kudalirika kwambiri. Mabaibulo onse chisanafike 1995 anali ofooka kwambiri pankhaniyi.

Kuchokera pamakina, mutu wa silinda udakhala wovuta. Zothandizira zawo zimapangidwa ndi moyo wochepa wautumiki wa lamba wanthawi, zovuta za malo ena pokonza mota, komanso kusowa kwa zonyamula ma hydraulic.

Pa nthawi yomweyo, malinga ndi ndemanga za eni galimoto ambiri, injini mosavuta kusamalira makilomita oposa 500 zikwi popanda kuwonongeka kwambiri. Kuti muchite izi, ndikofunikira kukonza zokonzekera munthawi yake komanso mokwanira pogwiritsa ntchito zida zapamwamba (zoyambirira) ndi zogwiritsira ntchito. Panthawi imodzimodziyo, tikulimbikitsidwa kuchepetsa mawu osamalira.

Mawanga ofooka

Pankhani iyi, choyambirira chimaperekedwa kwa mutu wa silinda. Kawirikawiri, ndi makilomita 200 zikwi zothamanga, ming'alu imawonekera mu prechamber ya silinda yachitatu. Ma jeep ndi omwe amakhudzidwa kwambiri ndi izi.

Mu 1995, wopanga adatulutsa Technical Note 2825A, kutsatira mosamalitsa komwe kumachepetsa chiopsezo chosweka mutu.

Ndi ntchito yosayenera, yankhanza komanso yaukali, injini yoyaka mkati imakhala yotentha kwambiri. Zotsatira zake zimakhala zomvetsa chisoni - kukonzanso kwakukulu kapena kusinthidwa kwa injini.

Injini yoyaka yamkati ilibe njira zochepetsera mphamvu zachiwiri. Zotsatira zake, injiniyo imathamanga ndi kugwedezeka kwamphamvu. Zotsatira zake ndi kufooka kwa mafupa a node ndi ma gaskets awo, maonekedwe a mafuta ndi kutuluka kozizira.

Si zachilendo kuti turbine iyambe kuyendetsa mafuta. Kawirikawiri izi zimachitika ku 100 zikwi makilomita a ntchito yake.

Chifukwa chake, injiniyo imafunikira chisamaliro chokhazikika komanso chapafupi. Pozindikira panthawi yake ndikuchotsa zolakwika, kudalirika ndi moyo wautumiki wa injini yoyaka mkati imawonjezeka.

Kusungika

Kusakhazikika kwa unit ndikokwanira. Monga mukudziwira, midadada ya aluminiyamu silinda sangathe kukonzedwa konse. Koma kukhalapo kwa manja achitsulo mwa iwo kumasonyeza kuthekera kwa kukonzanso kwathunthu.

Kuwonongeka kwa injini ya Renault J8S ndi mavuto | Zofooka zagalimoto ya Renault

Kupeza magawo ndi misonkhano ikuluikulu yokonzanso kumabweretsanso mavuto. Apa, mfundo yakuti mbali zambiri zotsalira ndizogwirizana zimabwera kudzapulumutsa, ndiko kuti, zikhoza kutengedwa kuchokera ku zosintha zosiyanasiyana za J8S. Vuto lokhalo ndi mtengo wawo.

Posankha kubwezeretsa, muyenera kuganizira mwayi wopeza injini ya mgwirizano. Nthawi zambiri njirayi idzakhala yotsika mtengo kwambiri.

Ambiri, injini J8S sizinali zopambana kwambiri. Koma ngakhale izi, ndi ntchito yoyenera ndi utumiki pa nthawi yake khalidwe, kunakhala olimba, umboni ndi mtunda wake mkulu.
