Renault J8S engine
Tusmo
Dabayaaqadii 70-meeyadii, taxanaha engine ee Faransiiska J waxaa lagu buuxiyey matoor naafto ah, kaas oo si guul leh loogu adeegsaday baabuur badan oo Renault ah.
Description
Nooca naaftada ee qoyska J8S ee cutubyada korantada ayaa la sameeyay waxaana la geliyay wax soo saar sanadkii 1979-kii. Siideynta waxaa lagu diyaariyay warshadda shirkadda ee Douvrin (France). Waxaa la soo saaray labadaba hami (1979-1992) iyo turbodiesel (1982-1996) versions.
J8S waa matoorka naaftada afar-dhululubo ee laynka 2,1-litir ah oo awoodiisu tahay 64-88 hp. leh oo qulqulaya 125-180 Nm.
Lagu rakibay baabuurta Renault:
- 18, 20, 21, 25, 30 (1979-1995);
- Master I (1980-1997);
- Gaadiidka I (1980-1997);
- Dabka I (1982-1986);
- Booska I, II (1982-1996);
- Safrane I (1993-1996).
Intaa waxaa dheer, matoorkaan waxaa lagu arki karaa koofiyadaha Cherokee XJ (1985-1994) iyo Comanche MJ (1986-1987) SUVs.
Balooggu wuxuu ka samaysan yahay aluminium aluminium ah, laakiin xargaha ayaa ah bir la tuuray. Xalka naqshadeynta ayaa si weyn u kordhisay saamiga cadaadiska.
Madaxa dhululubada sidoo kale waa aluminium, oo leh hal camshaft iyo 8 valves. Madaxu wuxuu lahaa nashqad qolka ka hor (Ricardo).
Piston-yada waxaa loo sameeyaa si waafaqsan nidaamka dhaqameed. Waxay leeyihiin saddex siddo oo laba ka mid ah ay yihiin cadaadis iyo hal xoqid saliid.
Nooca suunka ee wadida wakhtiga, iyada oo aan lahayn wareegayaasha wejiga iyo magdhawga biyaha. Khayraadka suunka waa mid aad u yar - 60 kun km. Khatarta jabka (boodboodka) waxay ku jirtaa foorarsiga tuubooyinka.
Nidaamka sifaynta wuxuu isticmaalaa bamka saliidda nooca gear. Xalka hal-abuurka leh waa joogitaanka tuubooyinka saliidda ee gaarka ah ee qaboojinta hoose ee pistons.
Bamka la isku duro ee lagu kalsoonaan karo ee nooca VE (Bosch) ayaa loo isticmaalaa nidaamka sahayda shidaalka.

Maxay ka dhigan tahay wax ka beddelka?
Iyada oo ku saleysan J8S, dhowr wax ka beddel ayaa la sameeyay. Farqiga ugu weyn ee qaabka saldhigga ayaa ahaa kororka awoodda sababtoo ah rakibidda turbocharger.
Marka lagu daro sifooyinka tamarta, fiiro gaar ah ayaa la siiyay nidaamka nadiifinta gaaska qiiqa, taas oo keentay in heerka heerarka deegaanka si weyn kor loogu qaado.
Isbeddelka naqshadda matoorka gubashada gudaha lama fulin, marka laga reebo walxaha ku dhejinta matoorka jidhka baabuurka, taas oo ku xidhan qaabkiisa.

Halaynta
Diesel J8S kuma kala duwana isku halaynta sare. Dhammaan noocyada ka hor 1995 waxay si gaar ah u daciifeen arrintan.
Laga soo bilaabo qaybta farsamada, madaxa dhululubada ayaa u rogay dhibaato. Wax ku biirintooda waxaa lagu sameeyaa nolosha adeeg yar ee suunka waqtiga, kakanaanta boosaska qaarkood marka la hagaajinayo mishiinka, iyo la'aanta wiishadaha hawo-qaadista.
Isla mar ahaantaana, sida laga soo xigtay dib u eegista milkiilayaasha baabuurta badan, engine si fudud u daryeeli in ka badan 500 kun oo km oo aan burbur weyn. Si tan loo sameeyo, waxaa lagama maarmaan ah in la fuliyo dayactirka jadwalka ah ee wakhtiga iyo si buuxda iyadoo la adeegsanayo qaybo tayo sare leh (asalka ah) iyo alaabooyinka. Isla mar ahaantaana, waxaa lagula talinayaa in la yareeyo shuruudaha dayactirka.
Dhibco daciif ah
Arrinkan, mudnaanta ayaa la siinayaa madaxa dhululubada. Caadi ahaan, 200 kun oo km oo orod ah, dildilaacyo ayaa ka muuqda qolka hore ee dhululubada saddexaad. Jeeps ayaa si gaar ah ugu nugul dhacdadan.
Sannadkii 1995-kii, soo-saaruhu wuxuu soo saaray Farsamo Farsamo 2825A, u hoggaansanaanta adag ee hoos u dhigtay khatarta dillaaca madaxa.
Hawlgalka aan habboonayn, qallafsanaanta iyo gardarrada, mishiinka gubashada gudaha ayaa u nugul kulaylka. Natiijadu waa wax laga xumaado - dib u habeyn weyn ama beddelka mootada.
Matoorka gubashada guduhu ma laha habab lagu qoynayo xoogaga dabciga ah ee heerka labaad. Natiijo ahaan, matoorku wuxuu ku socdaa gariir xooggan. Natiijadu waa daciifinta kala-goysyada qanjidhada iyo gaaskooda, muuqaalka saliidda iyo dareeraha qaboojiyaha.
Maaha wax aan caadi ahayn in marawaxadaha uu bilaabo inuu wado saliid. Caadi ahaan tani waxay ku dhacdaa 100 kun oo km oo hawlgalkeeda ah.
Sidaa darteed, matoorku wuxuu u baahan yahay feejignaan joogto ah oo dhow. Marka la ogaado waqtiga iyo ciribtirka khaladaadka, isku halaynta iyo nolosha adeegga matoorka gubashada gudaha ayaa kordhay.
Daryeelka
Joogteynta cutubku waa mid lagu qanco. Sidaad ogtahay, baloogyada aluminium ee dhululubada ah gabi ahaanba lama hagaajin karo. Laakiin joogitaanka gacmo-gashiyada birta ah ee ku jira waxay muujinaysaa suurtogalnimada dib u habeyn buuxda.
Helitaanka qaybaha iyo shirarka dib-u-soo-celinta waxay sidoo kale keentaa dhibaatooyin. Halkan, xaqiiqda ah in inta badan qaybaha firaaqada ah ay midaysan yihiin ayaa u yimid samatabbixinta, taas oo ah, waxaa laga soo qaadi karaa isbeddello kala duwan oo J8S ah. Dhibka kaliya ayaa ah qiimahooda.
Markaad go'aansanayso soo celinta, waa inaad tixgelisaa suurtogalnimada inaad hesho mishiinka qandaraaska. Badanaa doorashadani aad bay u jaban tahay.
Guud ahaan, mishiinka J8S wuxuu noqday mid aan aad u guulaysan. Laakiin iyada oo taasi jirto, iyada oo la adeegsanayo hawlgal ku habboon iyo adeeg tayo leh oo waqtigeeda ku habboon, waxay u noqotay mid adag, taas oo caddaynaysa masaafada sare.
