Kodi ndi zifukwa ziti zomwe chodulira burashi chanu sichikuyamba?

Pali zifukwa zitatu zazikulu zomwe makina odulira udzu sangathe kuyatsa: vuto ndi makina oyeretsera udzu, vuto ndi makina oyeretsera udzu; komanso kupsinjika kosakwanira kwa silinda.

Kawirikawiri, mavuto atatu akuluakulu sadzakhalapo nthawi imodzi. Chifukwa chake, ngati makina sangathe kuyatsa, choyamba muyenera kudziwa chomwe chayambitsa vuto, kudziwa kuti vutolo lili mu dongosolo liti, kenako tengani njira zothanirana nalo. Musamafulumire. Mutha kuyang'ana motsatira njira zotsatirazi.

① Choyamba, tembenuzani gudumu loyambira ndi dzanja. Likadutsa pakati pa dead pamwamba, limakhala lovuta kwambiri. Likatembenuza pakati pa dead pamwamba, gudumu loyambira limatha kutembenuka lokha kudzera mu ngodya yayikulu, zomwe zikusonyeza kuti kukanikizako ndi kwabwinobwino. Pa makina atsopano kapena makina akasinthidwa, kukanikiza nthawi zambiri kumakhala bwino.

② Palibe phokoso lophulika mu silinda mukayamba, chitoliro chotulutsa mpweya chimakhala chofooka, ndipo mpweya wotuluka ndi wouma komanso wopanda fungo. Izi nthawi zambiri zimasonyeza mavuto ndi makina amafuta. Muyenera kuyang'ana ngati chosinthira cha thanki yamafuta chayatsidwa, kuchuluka kwa mafuta mu thanki, ngati cholumikizira cha mafuta chatayidwa, ndikukanikiza chowonjezera cha carburetor kangapo kuti muwone ngati pali mafuta akutuluka. Mukapeza kuti zigawo zomwe zili pamwambapa ndi zabwinobwino ndipo sizingayambitsidwebe, mutha kutsanulira mafuta mu dzenje la chipinda cha spark ndikuyambiranso. Ngati sichikuyambabe kapena utsi nthawi zina umayaka kangapo kenako nkuzimitsa, zikutanthauza kuti dzenje loyezera mu carburetor likhoza kutsekedwa. Chotsani chipinda choyandama, tulutsani dzenje loyezera, ndikugwiritsa ntchito kupopera kapena kuyeretsa kuti muchotse. Musagwiritse ntchito waya wachitsulo kuti muchotse. Yesani dzenje.

③Palibe phokoso lophulika mu silinda panthawi yoyambitsa kapena phokoso lophulika limasokoneza, carburetor kapena muffler imabwerera m'mbuyo, ndipo mpweya wotuluka mu muffler umakhala wonyowa komanso wonunkhira ngati mafuta. Zochitika zomwe zili pamwambapa nthawi zambiri zimachitika chifukwa cha zolakwika mu dongosolo la ma circuit.

Ngati palibe kuphulika, choyamba muyenera kuchotsa chipinda cha spark, kuyika chipinda cha spark pa chotetezera spark plug pa chingwe champhamvu chamagetsi, kulumikizana ndi electrode ya mbali ya chipinda cha spark ndi gawo lachitsulo la makinawo, ndikutembenuza mwachangu gudumu loyambira kuti muwone ngati pali spark blue sparks zomwe zikudumphadumpha. Ngati sichoncho, yang'anani gawo lililonse la dera padera. Pa makina akale, ngati dera ndi dera la mafuta ndi zabwinobwino koma sizingayambebe, mutha kudziwanso ngati kuthamanga kwa compression kuli kotsika kwambiri. Pakadali pano, mutha kuchotsa spark plug ndikutsanulira mafuta pang'ono mu silinda, kenako ndikuyika spark plug. Ngati ikhoza kuyaka, zikutanthauza kuti kupsinjika kwa silinda sikwabwino. Mutu wa silinda uyenera kuchotsedwa kuti muwone ngati gasket ya silinda yawonongeka. Chotsani silinda ndikuwona ngati mphete ya pistoni ndi silinda zawonongeka kwambiri.

④Chigawo chilichonse chili bwino. Chifukwa kutentha kwa malo oyambira ndi kochepa kwambiri ndipo makinawo ndi ozizira kwambiri, mafutawo ndi ovuta kuwapanga atomu ndipo sikophweka kuwayatsa.

⑤ Ngati kulumikizana kwa payipi sikuli kolimba, pali mafuta ochepa komanso mpweya wambiri, kapena fyuluta ya mpweya yatsekeka, pali mafuta ambiri komanso mpweya wochepa, zidzakhala zovuta kuyambitsa.

⑥Kulowera kwa chingwe chokokera choyambira komanso liwiro loyambira zimakhudzanso ngati chingayambitsidwe.

⑦Ngati kutsegula kwa chitseko chamkati kwatsekedwa molakwika panthawi yoyambitsa, sizidzakhala zosavuta kuyambitsa.
