Waa maxay sababta uu waalka u foorarsado marka wakhtigu jabo?
Habka waalka wuxuu u shaqeeyaa sida soo socota: wakhtigan pistonku gaaro xarunta ugu sareysa ee meydka ah, labada valve ee qolka gubashada waa la xiray - cadaadis gaar ah ayaa ku dhex jira. Suunka jaban waxay keenaysaa xaqiiqda ah in waalka ha haysan wakhti aad ku xidho wakhti ka hor imaatinka pistonka. sidaas darteed, kulankooda ayaa u muuqda - isku dhac, taas oo si sax ah u horseedaysa xaqiiqda ah in waalka uu leexiyo. Markii hore, si looga hortago dhibaatadan oo kale, godad gaar ah ayaa lagu sameeyay ICE-yadii hore. Jiilka cusub ee matoorada gubashada gudaha, meelo la mid ah ayaa sidoo kale laga helaa, laakiin waxaa loogu talagalay oo kaliya in laga fogaado qallafsanaanta fiilooyinka inta lagu jiro hawlgalka mashiinka gubashada gudaha iyo haddii ay dhacdo jebinta suunka, gabi ahaanba ma badbaadin.
Marka laga eego dhinaca muuqaalka, laga bilaabo wakhtiga suunka wakhtigu jabo, kamaraduhu isla markiiba way istaagaan, hoos yimaada ficilka ilaha soo celinta ee hoos u dhigaya kamaradihiisa. Waqtigan xaadirka ah, crankshaft waxay si aan toos ahayn u sii socotaa dhaqdhaqaaqeeda wareeg ah (iyadoon loo eegin haddii qalabku ku hawlan yahay iyo in kale, kacaanku waxay ahaayeen kuwo hooseeya ama sarreeya, duuliyaha ayaa sii waday inuu u leexiyo). Taasi waa, pistons-yadu waxay sii wadaan inay shaqeeyaan, natiijadana, waxay ku dhufteen fiilooyinka furan ee wakhtigaas. Aad bay dhif u tahay, laakiin waxay dhacdaa marka valves ay waxyeeleeyaan piston laftiisa.
Sababaha suunka waqtiga jaban
- xirashada suunka sidaas oo kale ama tayadiisu liidato (geerka shaftu wuxuu leeyahay cidhifyo fiiqan ama saliid ka soo baxda shaabadaha saliidda).
- jeexjeexyada crankshaft.
- matoorka bamka (dhacdada ugu badan).
- dhowr ama hal camshaft wedges (tusaale ahaan, ay sabab u tahay xumaanta mid ka mid ah - si kastaba ha ahaatee, halkan natiijadu wax yar ayay ka duwan tahay).
- roogga xiisaddu ma furna ama rollers -ka ayaa la jeexjeexay (suunku wuu furmaa ama wuu adkeeyaa).
Matoorada casriga ah, maadaama ay ka awood badan yihiin kuwii iyaga ka horreeyay, waxay leeyihiin badbaado aad u yar. Haddii aan tixgelinno sababta, ku tiirsanaanta fiilooyinka, dhibaatadani waxay u muuqataa sababtoo ah masaafada yar ee u dhaxaysa iyaga iyo piston. Taasi waa, haddii wakhtigan uu pistonku yimaado, waalka uu maqan yahay, ka dibna isla markiiba wuu foorarsadaa. Tan iyo markii cadaadis weyn iyo cadaadis xagga hoose ee piston ma jiro jeexdin ka hooseeya waalka ee qoto dheer loo baahan yahay.
Waa kuwee ICE-yada uu waalka ku foorarsado?
Mashiinnada leh 8-valve ICE, waxa ay ku fooraraan kuwa ugu yar, laakiin 16 iyo 20 unug, hadday noqon lahayd shidaal ama naafto, qaloocdu waxay dhacdaa inta badan kiisaska. Run, mararka qaarkood waxay noqon kartaa hal ama dhowr valves, iyo haddii mishiinka gubashada gudaha uu ka shaqeeyay shaqo la'aan, markaa dhibaatadu way sii socon doontaa. Laakiin kiisaskan oo kale way yar yihiin, inta badan, cawaaqibka ka dhalan kara waa kuwo aan dib loo celin karin. Miis ay ku qoran yihiin liiska ICE-yada oo ay ku foorarsadaan dhammaan baabuurka caanka ah marka suunka wakhtigu jabo.

Sidee lagu ogaadaa in uu waalku qalloocan yahay?
Hubinta matoorka gubashada gudaha haddii tubooyinka la leexiyo wakhtiga nasashada ka dib
Arrinkan, midna baadhis muuqaal ah iyo tirooyinka lagu sheegay miisaska "valve bend" kuma caawin doonaan. Xataa haddii aad gacantaada ku hayso macluumaadka soo saaraha ee ku saabsan waxyeelada ay dhacdo suunka jaban, lama garanayo sida la isku halayn karo.
Haddii aad rabto inaad hubiso suurtogalnimada inaad ku leexiso fiilooyinka bisinka marka suunka waqtigu jabo, waxaad u baahan tahay inaad ka saarto suunka, dheji pistonka ugu horreeya TDC, u rog kamarada 720 digrii.
Haddii wax waliba si fiican u dhaceen oo uusan nasan, waxaad sii wadi kartaa hubinta - u tag piston labaad. Marka wax waliba ay halkaas ku fiican yihiin, markaa suunka jaban ee suurtogalka ah uma horseedi doono cawaaqib xun matoorka gubashada gudaha ee gaarigaaga.
Si aad uga fogaato dhibaatadan (la-laabashada valves-ka haddii ay dhacdo nasasho), waa inaad si joogto ah ula socotaa xaaladda iyo xiisadda suunka waqtiga. Marka dhawaaqa ugu yar ee aan la aqoon uu soo baxo inta lagu jiro hawlgalka, waa inaad isla markiiba isku daydaa inaad ogaato sababta ay u dhacday, hubi xaaladda rollers iyo bamka.
Markaad iibsanayso baabuurka la isticmaalay, beddel suunka wakhtiga isla markaaba, iyada oo aan loo eegin waxa iibiyahu kuu sheego. Ka dibna su'aal degdeg ah sida waalka ma laabtaa markuu jabo Laguma qasi doono.
Calaamadaha waalka qaloocsan
Marka suunka jabo, ka dibna si fudud u beddelo suunka wakhtiga, rajaynaya in wax walba ay tageen natiijo la'aan oo aad bilowdo mishiinka, maaha mid u qalma. Gaar ahaan haddii matoorka gubashada gudaha uu ku jiro liiska kuwa uu waalka ku foorarsado. Haa, waxaa jira waqtiyo marka laabtu aysan weyneyn oo dhowr valves aysan si fiican ugu habboonayn kooraska, ka dibna waxaad u rogi kartaa bilawga, laakiin inta badan falalka noocan oo kale ah ayaa sidoo kale ka sii dari doona xaaladda. Maadaama dhaawac yar uu wax kastaa shaqayn doono oo uu wareego, si kastaba ha ahaatee, matoorka gubashada gudaha ayaa ruxmi doona, cawaaqibkuna wuu ka sii dari doonaa.
Way fiicantahay in aad ka saarto "madaxa" si aad u hubiso tan muuqaal ahaan ama aad ku buuxiso kerosene, si kastaba ha ahaatee, waxaa jira dhowr siyaabood oo lagu hubin karo in waalka uu leexsan yahay iyada oo aan la kala furfurin mishiinka gubashada gudaha.
Calaamadda ugu weyn haddii valves ay leexdaan - yar ama gebi ahaanba cadaadis la'aan. Sidaa darteed, waxaad u baahan tahay inaad cabbirto cadaadiska ku jira dhululubada. Laakiin, falalka noocan oo kale ah ayaa khuseeya haddii shafka la rogi karo oo aan waxba ku nasan meel kasta. Markaa waxa ugu horreeya ee la sameeyo waa in la rakibo suunka cusub, gacanta, adoo adeegsanaya boodhka HF, ku rog dhammaan habka qaybinta gaaska dhowr wareeg (waxaad u baahan tahay inaad furto shumacyada isku mar).
Sida loo hubiyo in waalka leexsan yahay
Si loo go'aamiyo in tariinka waalka qaarkood uu qalloocan yahay, dhab ahaantii shan wareeg oo gacan-rogid ah oo furaha ku leh biraha birta ayaa ku filan. Haddii ulaha ay yihiin kuwo qumman, ka dibna wareeggu wuxuu noqon doonaa bilaash, foorarsan - culus. Iyo sidoo kale waa inay jiraan 4 dhibcood oo si cad loo taaban karo (hal kacaan) oo iska caabin ah dhaqdhaqaaqa pistons. Haddii caabbinta noocaas ah aan la dareemin, ka dibna dib u celi shumacyada, mid mid u fur oo mar kale u rog rogrogmada.
Awoodda jilitaanka gacanta, iyada oo mid ka mid ah shumacyadu maqan yihiin, way fududahay in la fahmo dhululubada gaarka ah ee valve(yada) la leexiyay. Si kastaba ha ahaatee, habkani had iyo jeer ma awoodi doono inuu kaa caawiyo inaad si sax ah u ogaato haddii uu jeexan yahay iyo in kale.
Haddii shafka uu u leexdo si xor ah, markaa waad awoodaa ku hubi cabirka cadaadiska. Ma jiro qalab noocaas ah? Macnaha samayn pneumotest, Intaa waxaa dheer, hubinta cidhiidhiga dhululubada waa habka ugu saxsan, kaas oo ka jawaabi doona sida taarikada waalka ee ku habboon sadarsyada, iyada oo aan lahayn cawaaqib dheeraad ah marka la duubayo bilawga iyo iyada oo aan la rakibin suunka cusub.
Sidee loo hubiyo in waalka laftiisa uu leexsan yahay?
Pneumotest, uma baahnid inaad baabuurka u soo jiido xarunta adeegga, adiga laftaadu waxaad ogaan kartaa in dhululubada uu ku dheggan yahay iyo in kale. Ugu fudud:
- soo qaado qayb ka mid ah tuubada iyadoo loo eegayo dhexroorka ceelka shumaca;
- fur shumaca;
- u dhig bisinka dhululubada meel sare oo meyd ah (valves xiran) mid mid;
- si adag u geli tuubada ceelka;
- waxa aad isku daydaa in aad isku daydo in aad ku afuufo qolka gubanaya (hawo soo marta - foorarsato, ma dhaafto - "lagu dhex maro").
Tijaabo isku mid ah ayaa lagu samayn karaa iyada oo la isticmaalayo kombaresarada (xitaa mishiinka). Run, waxaad u baahan doontaa inaad waqti yar ku bixiso, markaad u baahan tahay inaad diyaargarowdo. Ku daadi korantada dhexe shumaca hore, oo ku dheji tuubo caarada dhoobada ah (si fiican ugu hagaajiya xajin). Ka dib cadaadiska ku shub dhululubada (waa haddii piston-ka ku jira uu yaallo TDC).
