Indlela ukusetha isikhathi ukuthungela

Ngaphambi kokuqhubeka eyohlinzwa ezinjalo, njengoba ukuchayeka we ukuthungela, udinga ukuba uzijwayeze ezinye izincazelo. Ngokwesibonelo, isikhathi ukuthungela. Kuyaziwa ukuthi ngesikhathi lapho piston sihamba lo mvimbo kokucindezelwa, le crankshaft kwenza ukujika nengxenye, it is ijikelezwe by 180 degrees. Lokhu kumayelana hhayi kuphela unhlangothi kokucindezelwa, kuyilapho bonke abanye, ngenxa yalokho a yokusebenza umjikelezo ephelele injini ezine-unhlangothi kwenza linemibhikisho ezimbili noma 720 degrees.

Kukhona into efana nenombolo octane of uphethiloli. Ngeke bangene imininingwane kanjani kukalwa, kubalulekile ukuthi ihlukile. Manje, uphethiloli nge ezahlukene isivinini octane ukuthungela ihlukile kakhulu. Uma isikhathi ukuthungela isethwe ngokunembile ukuthi piston isezingeni TDC, le ukuthungela kwenzeka ngesikhathi lapho uya phansi ngaphansi isenzo inertia we ligcina uthi lokuphotha luzungeza.

Ukuze uvimbele lokhu ukuthi kwenzeke, futhi ukuqhuma ingxube Senzeka ngaso kanye nendawo phezulu efile, isikhathi ukuthungela isethwe. Ngokwesibonelo, uma piston Vaz-2106 ifinyelela TDC 4-5 mm, crankshaft kuze ngokugcwele 180 uyolahlekelwa degrees 10. Uma Imi lokuqala yobukhulu 2-3 mm, bese yesibili sehliselwe 5 degrees. Lona engeli ezivamile, ezisetshenziswa uma usebenzisa AI-80 futhi AI-92, ngokulandelana.

Manje ngqo ku bembonisa ukuthungela. Cabangela le nqubo njengesibonelo uhlelo non-contact, ukuze sigweme izinkinga ne igebe oxhumana. Okokuqala udinga ukucacisa unhlangothi kokucindezelwa e uMbhalo kuqala. Lokhu kwenziwa kusetshenziswa uboya, okuyinto amvalele inhlansi ipulaki imbobo ikhanda ke ijikelezwe kancane ngoba ratchet crankshaft. Uma isilinda kokucindezelwa muhle, uboya kufanele fly ekuseni emjikelezweni.

Njengomthetho, lo isondo lokugijimisa indiphi elenzelwe into esindayo crankshaft esembozweni has a ilebula. Lena isikhathi ukuthungela. Bona sihambisana engeli ngenhla, kanye TDC yena, isiqondiso ukuzungeza. Ngokusho ilebula zakamuva ngokuvamile wadalula ukuthungela ngoba AI-95 futhi AI-98, ngakho ukusetshenziswa loluphawu pretty ezingavamile.

Ngemva ngokubeka crankshaft ku isikhundla mshini ayesebekwa distributor ukuthungela, ezihlukahlukene brand kanye tinkhulumo, bahlukile, futhi timer ufakwa slot eyamukelayo, bese isilungisiwe.

Kodwa mangisho ekuqaleni wadalula ukuthungela isikhathi kungase kungabi sokugcina.

ukulungiswa Okuningi ngokucophelela ukuthungela wenziwa emva injini iqala, elifudumele-up ukuze izinga lokusebenza evamile, futhi ngemva efanele ukulungiswa we carburetor at lutho. Ngenxa yalesi othayiphiwe e lwesithathu isivinini igiya 35-40 km / h, ke inkinobho wesine. Ngemva kwalokhu detonation emfushane kumele kwenzeke, okuyinto ubalekela ingakapheli imizuzwana emihlanu. Uma uhlala isikhathi eside, kubalulekile ukuba ujike izindlu distributor bebheke ukujikeleza roller, noma okuphambene nalokho, uma engqongqoza wayengekho.

Ekuphetheni, kufanele kusho ukuthi nepravlny kusengaphambili engela, ikakhulukazi ekuseni kakhulu, okuholela umonakalo omkhulu yokuxhuma induku piston iqembu, ezifana, isibonelo, ziba ngcono phezulu ikhanda porshpaltsa induku noma entanyeni crankshaft ezansi.
