Chidziwitso Choyenera

Masitepe osamalira mutu wa silinda: kuyang'anira ndi kuphatikizira

Njira yowunikira mutu wa cylinder

 

"Momwe mungakulitsire mphamvu ya injini ya dizilo zimadalira mphamvu yosindikiza ya kapu yatsopano. Izi zimafuna kuti pamwamba pa chipewacho chikhale chokwera kwambiri, osachepera kufika pamlingo wa 6 kapena apamwamba. Komabe, injini ya dizilo ikamakula ikugwira ntchito. Nthawi, pambuyo pa kugwedezeka kwamphamvu pafupipafupi, zopindika zing'onozing'ono zidzachitika pamene nthawi yogwiritsira ntchito ikuwonjezeka, zomwe zimafuna kuti flatness ya kapu ifufuzidwe bwino panthawi yokonzanso.", Ngati kusagwirizana kumafika pamwamba pa 0.10 mm, m'pofunika kugwiritsa ntchito makina opera odzipereka. kwa pamwamba akupera, koma kuchuluka akupera sayenera kukhala yaikulu kupewa kukhudza psinjika chiŵerengero cha injini ndi zimakhudza ntchito yake ntchito.Pasakhale ming'alu pakati pa mabowo.Ming'alu iyi siwoneka pokonzanso, ndipo kuzindikira zolakwika kuyenera kuchitidwa pakukonzanso mutu wa silinda.

 

1. Kuzindikira kwa mawu a Cylinder head stria

 

Nthawi zambiri, ming'alu imatha kuchitika mundege ya cylinder block, mabowo owongolera ma valve, mabowo owonekera, ndi makoma a jekete lamadzi ozizira.Kuyang'ana kumatha kuchitidwa ndi kuyesa kwa hydraulic, kuyesa kwa pneumatic, kuzindikira zolakwika za maginito, ndi njira zina.

 

2. Kuwunika kwa cylinder mutu flatness

 

Ngati pali zipsera, dzimbiri, kapena kuvala kosagwirizana pa makwerero a chivundikiro chosasinthika ndi gasket ya silinda, iyenera kuyang'aniridwa.Kutsetsereka kuyenera kufufuzidwa ndi m'mphepete mowongoka komanso ndi geji yomveka.Kuchuluka kwa makina aliwonse okhala ndi cylinder liner kuyenera kukhala 0.1270 ~ 0.1524mm.Pamene makulidwe a chivundikiro chosasunthika afika malire ogwiritsira ntchito, ayenera kutayidwa mosamala.Makulidwe osachepera a Tangmingqi 56BT mndandanda wa dizilo chivundikiro ndi 11.00m01, pazipita ndi 111.25m, ndipo malire ndi 110.240101.Zindikirani kuti pamene pamwamba pa chivundikiro chosasinthika sichikukonzedwanso, mapepala a silinda a 0.7939mm okha amaloledwa.Makulidwe a X a mutu wa silinda wa injini ya dizilo ya KTTA sayenera kuchepera 119.76mm.

 

Ndege zam'mwamba ndi zam'munsi za mutu wa silinda ziyenera kukhala zofanana, zosagwirizana mkati mwa 0.13mm, apo ayi dzenje la mpando wa silinda likhoza kukhala lopunduka.

 

3. Yang'anani kuthamanga kwa silinda

 

Kutentha kwamafuta a injini sikuyenera kutsika kuposa 30% C mukamayang'ana kuthamanga kwa silinda.Njira zodziwira kuthamanga kwa silinda ndi izi: (1) Tsekani kusintha koyambira, tsegulani throttle kwathunthu, ndipo gwiritsani ntchito cylinder pressure tester VAG1381/VAG1763 kuti muzindikire kupanikizika.(2) Yambitsani choyambira mpaka mtengo wapakati womwe ukuwonetsedwa pa tester sukuwonjezekanso.

 

2,Kuchotsa ndi kukhazikitsa mutu wa silinda

 

Mukakonza mutu wa silinda, zisindikizo zoyenera, ma gaskets, mtedza wodzitsekera, ndi mabawuti okhala ndi torque yomangika iyenera kusinthidwa.Mukayika chophimba kumaso ndi camshaft, malo olumikizirana pakati pa tappet ndi kamera ayenera kuthiridwa ndi mafuta a injini.Manja oteteza pulasitiki a silinda ayenera kuchotsedwa musanayike valavu.Poika chivundikiro chatsopano kapena cylinder head gasket, choziziritsira chakale chiyenera kutsanulidwa ndikudzazidwa ndi chozizirira chatsopano.Mitu ya cylinder yokhala ndi ming'alu pakati pa mipando ya valve ingagwiritsidwebe ntchito ngati kutalika kwa ming'alu sikudutsa 3mm, popanda kukhudza moyo wawo wautumiki.

 

1. Disassembly ndi msonkhano wa kudya kochuluka

 

(1) Kuchotsa kuchuluka kwa kudya.

 

Musanaphatikize, yang'anani mawu achinsinsi a wailesi yagalimoto, zimitsani choyatsira, chotsani waya wapansi wa batri, kukhetsa choziziritsa kukhosi, ndipo pochotsa cholumikizira, chotsani kapena kudula zingwe zonse ndi zingwe.Pakuyika, iyenera kukhazikitsidwanso momwe ilili.Kulowa mochuluka

 

Mayendedwe a pipeni ndi disassembly ndi awa:

 

D Chotsani thanki yoziziritsira ndi payipi.

 

Chotsani throttle chingwe pa throttle control unit ndi bulaketi (popanda kuchotsa throttle chingwe clamp), chotsani payipi ya mpweya pa throttle control unit, chotsani chitoliro cha vacuum chopita ku activated carbon, ndikutulutsa chitoliro cha vacuum kupita ku brake booster. .

 

@Chotsani sensa ya kutentha kwa mpweya ndi mapulagi a unit throttle control, ndiyeno mutulutse mapulagi kuchokera ku holo yolandirira sensor.

 

Chotsani mabawuti omangirira amafuta ndikukokera chitoliro cha vacuum kutali ndi chowongolera chamafuta.Chotsani chochulukira chamafuta ndi jekeseni wamafuta papaipi yolowera ndikuchiyika pansalu yoyera kuseri kwa chipinda cha injini.6 Chotsani payipi yozizirira ku chitoliro chapamwamba chozizirira.Chotsani mabawuti omangira chitoliro choziziritsa panjira yolowera komanso pompopompo flange yozizirira kumbuyo kwa mutu wa silinda.Chotsani payipi ya mpweya wa crankcase pamalo olowera, chotsani bulaketi yolowera, tulutsani sikelo yamafuta, masulani mabawuti omangirira panjapo, ndi pindani zochulukirapo.Gwiritsani ntchito nsalu yoyera kuti mutseke polowera mpweya pa chivundikiro cha chisokonezo cha mpweya.(2) Kukhazikitsa kochulukira kudya.

 

Bwezerani gasket ndikusindikiza, ndikuyika zochulukira munjira yochotsamo.Pakuyika, tcherani khutu pakusintha chingwe cha throttle ndikudzaza choziziritsa.Mukatha kukhazikitsa, mverani izi: D Mukalumikiza batire, lowetsani mawu achinsinsi oletsa kuba,

 

@ Tsekani kwathunthu zenera lakutsogolo lamagetsi ndi chosinthira magetsi.Gwiritsirani ntchito ma switch onse amagetsi ndi mawindo otsekedwa (osachepera 1s) kuti mutsegule ntchito imodzi yokha.

 

3 Sinthani wotchi.

 

4. Chitani zofananira zigawo zowongolera throttle.

 

2. Disassembly ndi msonkhano wa silinda mutu

 

(1) Disassembly masitepe a chivundikiro chamutu cha silinda:

 

D Chotsani zigawo zotumphukira za mutu wa silinda ya injini.

 

Masulani mabawuti a chitoliro cha mpweya wa crankcase pa zotchingira kutentha ndi malo amutu wa silinda, ndipo pang'onopang'ono sunthani chitoliro chopumira cha crankcase kumbali imodzi.

 

S Chotsani mlonda wapamwamba wa lamba wanthawi.

 

Chotsani pulagi ya koyilo yoyatsira, chotsani waya wapansi, ndi kumasula bawuti yomangira ya koyilo yoyatsira.

 

Chotsani chivundikiro cha silinda kumutu ndikuchotsa chivundikiro cha silinda.

 

(2) Ikani mutu wa silinda mu dongosolo lochotsamo.Chisamaliro chapadera chiyenera kulipidwa pakuyika: Ngati cylinder head gasket yawonongeka, iyenera kusinthidwa.

 

3. Kusamalira mutu wa silinda

 

(1) Disassembly masitepe a silinda mutu:

 

D Yang'anani mawu achinsinsi a wailesi yagalimoto.Zimitsani choyatsira ndikuchotsa waya wapansi wa batri.Chotsani choziziritsa kukhosi

 

Chotsani chitoliro chotumizira mafuta ndikubwezeretsa chitoliro pa chitoliro chogawa mafuta.Pochotsa, tcherani khutu ku kuthamanga kwa mafuta.Mukachotsa, tsekani chitolirocho kuti musawononge dongosolo lamafuta.Chotsani kuchuluka kwa utsi ndi 2-way catalytic converter kuchokera pazochulukitsa zambiri.

 

Chotsani mapulagi a activated carbon canister solenoid valve, ignition power terminal stage, ndi air quality mita mu dongosolo.

 

Chotsani cholumikizira cha payipi ndikuchotsa nyumba ya fyuluta ya mpweya.Chotsani pulagi pa koyilo yoyatsira ndi pulagi pa sensa yoziziritsa kutentha kwa mame.Tsegulani zingwe za mizere yonse kuchokera pamutu wa silinda ndikuyika mawaya pambali.Tulutsani payipi yozizirira yomwe imatsogolera ku kusinthana kwa kutentha kumbuyo kwa kapu ya gasi (choyamba masulani chosungira pa flange yolumikizira).Chotsani mlonda wapamwamba wa lamba wa nthawi, tembenuzirani crankshaft kunjira yozungulira injini kudzera pa bawuti yapakati pa crankshaft timing lamba, ndipo sinthani crankshaft kuti ikhale pakatikati pakufa pa silinda yoyamba.

 

Masulani chomangira lamba ndi T45 screwdriver, kanikizani chomangira lamba wanthawi, chotsani lamba wanthawi yake pa pulley ya nthawi ya camshaft, masulani bawuti ya Torx, ndikusunthira kutsogolo mbale yomangirira.O Chotsani chophimba kumutu cha silinda

 

Tsegulani mabawuti amutu wa silinda ndikuchotsa mutu wa silinda

 

(2) Kuyendera mutu wa silinda

 

Yezerani mutu wa silinda ndi m'mphepete mowongoka kapena makulidwe ake, ndipo mawonekedwe ovomerezeka kwambiri ndi 0.1mm.Monga momwe chithunzi 3 chikusonyezera, kukula kwa silinda (kukakula) sikuyenera kupitirira gawo locheperapo a, ndi gawo locheperapo a=139.25mm.
