M'zaka zaposachedwa, chidwi chochulukirapo chaperekedwa pachitetezo chazida zopangira kumayiko ena.Mwanjira iyi, chitetezo chazidacho chimakhala bwino kwambiri, ndipo chimatha kupeweratu ngozi zachitetezo zomwe zimachitika chifukwa chogwiritsa ntchito molakwika.

Thekutsekedwa kwa valveya dongosolo la mapangidwe ndi apadera pakali pano.Kutsekera kwa vavuku kumayendetsedwa makamaka ndi chogwirira cha valve chokhazikika.Mapeto amodzi a zotsekera valavu amalumikizidwa ndi bawuti ya nangula ya bonnet.Njira yolumikizira imapangidwa ndi mtedza wa 2, kulumikiza unyolo woyendetsa ndi pini pakati, kulunga mbali imodzi ku bonnet nangula wa zida zake zothandizira (waya wa nati wopangidwa ndi ulusi umafanana ndi waya wa bonnet nangula), ndi mapeto ena ali ndi mgwirizano wa inchi ulusi wolumikizidwa ndi nati wa ulusi, ndi chogwirira valavu ndi circumvented ndi unyolo pagalimoto.Mbali ziwiri za makina oyendetsa galimoto zimagwirizanitsidwa ndi mgwirizano wa ulusi wa inchi ndi zikhomo, ndipo chogwirira ndi chivundikiro cha valve zimagwirizanitsidwa molunjika.Njira yolumikizira ngati valavu ikupezeka kuti yatsekedwa, valavu silingatsegulidwe pokhapokha mgwirizano womwe uli pakati umasulidwa kapena kuwonongeka.

Pokonza kapena kutsegula ndi kutseka valavu, ndikwanira kupotoza mgwirizano pakati.Ma valve otsekera amagwiritsidwa ntchito makamaka m'ma valve ena omwe nthawi zambiri amatsekedwa ndi kutseguka, ndipo ma valve ena omwe amatsegulidwa ndi kutsekedwa panthawi yokonza, ndi ma valve ena omwe ayenera kutsekedwa angagwiritsidwe ntchito.Loko imathanso kutseka ma valve a 2, omwe makamaka amawateteza kuti asayambitse ngozi zachitetezo chifukwa cha zolakwika zogwirira ntchito.

Kutsimikiziridwa molingana ndi ntchito zothandiza, ndizothandiza komanso zimapulumutsa zambiri zopangira.Kutsekedwa kwa ma valveZakhala zikugwiritsidwa ntchito m'makampani ambiri opanga magetsi, ndipo zotsatira zake ndi zabwino kwambiri.Amagwiritsidwa ntchito nthawi zonse pakusintha kwamagetsi ndi kukonza nthawi kuti apewe zolakwika zogwirira ntchito ndikuwonetsetsa kuti makina ndi zida zikuyenda bwino.
