Makiinadda lagu buufiyo: Qoondaynta iyo dayactirka

Sannad kasta, shuruudaha mashiinka naaftada ee shuruudaha sida awoodda, saaxiibtinimada deegaanka iyo dhaqaalaha oo kordho. Oo kaliya oo ah habka ugu fiican ee isku dhafka dabka loo oggol yahay waxay u oggolaaneysaa in la buuxiyo shuruudahan. Sidaas daraadeed, nidaamka cirbadeynta oo idil waa in uu si fiican u shaqeynaa, siinta buufinta ugu yar ee cadaadiska sare.

Nidaamka noocan oo kale ah, oo isku daraya qalabka shidaalka iyo mishiinka hal unit, waa mashiinka-boogaha. Si la mid ah mashiinnada duritaanka, mashiinka injirta ayaa isku duraa miisaan gaar ah oo ku jira wakhtiga saxda ah. Sababtoo ah xaqiiqda ah in mid kasta oo ka mid ah mishiinka matoorka ah uu jiro hal mashiinka-injirta, nidaamka noocan oo kale ah ma jiraan tuubbo shidaal oo bamka shidaalka ah.

nozzles qalab ka mid ah madaxa dhululubo amro Injector unit naaftada. Si aad ugu dhaqdhaqaaqdo qashin qubka waxaa jira 4 khaas ah. Ciidamada on the injectors unit plungers loo kala qaado iyada oo rookaha ah. Sababtoo ah qaabka gaarka ah ee gawaarida lagu riixo mashiinka-boogaha, dhagaxshuhu wuxuu marka hore u kaco si adag oo markaas si siman hoos ugu dhacaya.

Xilligan marka uu dhagaxgu sare u kaco, foorariyaha ayaa hoos u riixaya xawaare wayn. Sidaa darteed, cadaadis sare ayaa soo baxa. Marka gacanta rookaha bilaabo inuu si tartiib ah u dhici, sida Cabbeeyaha bilaabmin si aad u yarayso iyo dhaqdhaqaaqa uniform kor. Naqshadani waxay u oggolaataa in shidaalka uu ku soo galo qolka cadaadiska sare si aan fiicnayn, iyada oo aan loo sameynin goobooyin hawo ah. Waqtiga iyo mudada duritaanka ayaa xakamaynaya bamka gacanta lagu xiro ee balaastiga. Ujeedada this, iyada oo electronic unit gacanta ku bixisey danab. Xitaa marka la eego xarriiqyada yar ee waraaqaha warshadaha, inta lagu jiro buufinta shidaalka waa badanaa la isticmaalay, mashiinka wuxuu bilaabmaa inuu sameeyo "dhawaaqa".

Bamka mashiinka dhaadheer wuxuu noqon karaa saddex nooc: piezoelectric, electromagnetic, electro-hydraulic. Iyada oo waalka solenoid biiyaha dhigay sida shidaalka naaftada iyo matoorada, oo uu leeyahay qorshe fudud: biiyaha iyo waalka solenoid irbad buufis. Unugyada korontada ku shaqeeya ayaa lagu rakibay oo kaliya mashiinnada naaftada, kuwaas oo inta badan ka shaqeeya nidaamka Komon Rile. Piezoelectric waxaa loo tixgeliyaa midka ugu haboon ee matoorada naaftada ah. Bamka injirta ayaa soconaya illaa 4 jeer ka dhakhso badan injirta electromagnetic, iyo qiyaasta shidaalka la isku duro ee saxda ah.

Dayactirka unugyada waa in la sameeyaa marka calaamadaha soo socda la arko: Isticmaalka shidaalka si weyn ayuu u kordhay, guuldarada degdegga ah ee barta gaaska, shidaalka daadinta ama foorjirta nidaamka qiiqa. Baadhitaanada dareemka ee baabuurka waa kuwo aan degganeyn: fallaadhaha tikometerka joogtada ah "boodboodaya" si bilaa sabab ah. Hubinta cirbadaha, iyo sidoo kale in dayactirkooda lagu sameeyo saldhigyo gaar ah, sidaa daraadeed way adagtahay in la dayactiro naftaada: cadaadiska oo keliya 10% ka sareeya magaca sababaha keena mishiinka cilladaysan. Oo xataa haddii shaqada ee nidaamka shidaalka ma siin abuuray welwel, Baadhista Injector - habka ah in lagu talinayaa in ka dib kasta 60 000-70 000 km baabuurta orod.
