Renault J8S injini
Zviri mukati
Mukupera kwema70s, iyo French J injini yakatevedzana yakazadzikiswa neinjini yedhiziri, iyo yakabudirira kushandiswa pamotokari zhinji dzakakurumbira dzeRenault.
tsananguro
Iyo dhiziri vhezheni yeJ J8S mhuri yemagetsi mayunitsi yakagadziridzwa uye yakaiswa mukugadzirwa muna 1979. Kuburitswa kwakarongwa pachirimwa chekambani muDouvrin (France). Yakagadzirwa zvese zviri zviviri mukushuvira (1979-1992) uye turbodiesel (1982-1996) shanduro.
J8S i 2,1-litre in-line four-cylinder dhizeli injini ine simba re 64-88 hp. pamwe uye torque 125-180 Nm.
Yakaiswa paRenault mota:
- 18, 20, 21, 25, 30 (1979-1995);
- Tenzi I (1980-1997);
- Traffic I (1980-1997);
- Moto I (1982-1986);
- Nzvimbo I, II (1982-1996);
- Safrane I (1993-1996).
Uyezve, injini iyi inogona kuonekwa pasi hoods pamusoro Cherokee XJ (1985-1994) uye Comanche MJ (1986-1987) SUVs.
Iyo cylinder block inogadzirwa nealuminium alloy, asi liner dzakakandwa simbi. Iyi sarudzo yekugadzirisa yakawedzera zvakanyanya kuwanda kwekumanikidza.
Musoro wecylinder zvakare aluminium, ine camshaft imwe uye 8 mavharuvhu. Musoro wacho waive ne pre-chamber design (Ricardo).
Mapistoni anogadzirwa maererano nehurongwa hwechinyakare. Vane zvindori zvitatu, maviri acho ari compression uye imwe mafuta scraper.
Bhandi-mhando yenguva yekutyaira, isina phase shifters uye hydraulic compensator. Bhandi rekushandisa idiki - 60 zviuru zvemakiromita. Ngozi yekutyora (kusvetuka) iri mukukotama kwemavharuvhu.
Iyo lubrication system inoshandisa giya mhando yepombi yemafuta. Mhinduro yekuvandudza kuvepo kweakakosha maoiri maoiri ekutonhodza pasi pepiston.
Iyo yakavimbika jekiseni pombi yeVE mhando (Bosch) inoshandiswa mumafuta ekupa system.

Kugadziridza kunorevei?
Kubva paJ8S, shanduko dzinoverengeka dzakagadzirwa. Musiyano mukuru kubva pachigadziko modhi yaive kuwedzera kwesimba nekuda kwekuiswa kwe turbocharger.
Pamusoro pemaitiro emagetsi, kutarisisa kwakawanda kwakabhadharwa kune yekupedza gasi yekuchenesa sisitimu, semhedzisiro iyo iyo dhigirii yezvakatipoteredza emission standard yakasimudzwa zvakanyanya.
Shanduko mukugadzirwa kweinjini yekupisa kwemukati haina kuitwa, kunze kwezvinhu zvekuisa mota kumuviri wemotokari, zvichienderana nemuenzaniso wayo.

Kuvimbika
Diesel J8S haina kusiyana mukuvimbika kwepamusoro. MaBhaibheri ese asati asvika 1995 akanga asina kusimba panyaya iyi.
Kubva pachikamu chemuchina, musoro wecylinder wakava dambudziko. Mupiro wavo unoitwa nehupenyu hwakaderera hwebasa rebhandi renguva, kuoma kwezvimwe zvinzvimbo pakugadzirisa mota, uye kushaikwa kwema hydraulic lifters.
Panguva imwecheteyo, maererano nekuongororwa kwevaridzi vakawanda vemotokari, injini inotarisira nyore kupfuura 500 zviuru zvemakiromita pasina kukanganisa kukuru. Kuti uite izvi, zvinodikanwa kuita gadziriro yakarongwa panguva yakakodzera uye zvizere uchishandisa yakakwirira-yemhando (yepakutanga) zvikamu uye zvinodyiwa. Panguva imwecheteyo, zvinokurudzirwa kuderedza mitemo yekuchengetedza.
Nzvimbo dzisina kusimba
Munyaya iyi, kukoshesa kunopiwa kumusoro wecylinder. Kazhinji, ne200 zviuru zvemakiromita ekumhanya, kuputika kunoonekwa mu prechamber yechitatu cylinder. Jeeps inonyanya kubatwa nechiitiko ichi.
Muna 1995, mugadziri akaburitsa Technical Note 2825A, kutevedzera zvakasimba izvo zvakaderedza njodzi yekutsemuka musoro.
Nekushanda kusina kunaka, kwehasha uye kwehasha, injini yekupisa yemukati inowanzopisa. Mhedzisiro yacho inosuruvarisa - kugadzirisa kukuru kana kutsiviwa kwemota.
Injini yekupisa yemukati haina nzira dzekudzikisa simba rechipiri-kurongeka inertial. Nekuda kweizvozvo, mota inomhanya nekudengenyeka kwakasimba. Mhedzisiro yacho kupera simba kwemajoini emanodhi uye gaskets yavo, kutaridzika kwemafuta uye inotonhorera inodonha.
Hazvisi zvisizvo kuti turbine itange kutyaira mafuta. Izvi zvinowanzoitika ku100 zviuru zvemakiromita ekushanda kwayo.
Nokudaro, injini inoda kugara uye kunyatsoteerera. Nekuona panguva uye kubviswa kwezvikanganiso, kuvimbika uye hupenyu hwebasa rejini yekupisa kwemukati inowedzera.
Kuchengetedza
Kuchengetedza kwechikwata kunogutsa. Sezvaunoziva, aluminium cylinder blocks haigone kugadziriswa zvachose. Asi kuvapo kwe-cast-iron sleeve mukati mavo kunoratidza mukana wekugadzirisa zvakakwana.
Kuwana zvikamu nemagungano ekugadzirisa zvakare kunokonzera mamwe matambudziko. Pano, chokwadi chekuti akawanda ezvimedu zvakabatana anouya kuzonunura, ndiko kuti, anogona kutorwa kubva kwakasiyana kugadziridzwa kweJ8S. Dambudziko chete mutengo wavo.
Paunenge uchifunga nezve kudzoreredza, iwe unofanirwa kufunga nezve mukana wekutora chibvumirano injini. Kazhinji iyi sarudzo ichave yakachipa zvakanyanya.
Kazhinji, injini yeJ8S yakave isina kubudirira zvikuru. Asi pasinei neizvi, nekushanda kwakakodzera uye sevhisi yehutano panguva, yakave yakasimba, sezvinopupurirwa nekukwirira kwayo mileage.
