Pane chubhu yekusveta mweya iri pedyo nefirita yemhepo. Chii chiri kuitika?
Iyi ichubhu iri mu crankcase ventilation system inotungamirazve gasi rekubuda mumhepo kuenda ku intake manifold kuti ripiswe. Injini yemota ine crankcase forced ventilation system, uye kana injini ichishanda, imwe gasi inopinda mu crankcase kuburikidza ne piston ring. Kana gasi rakawandisa rikapinda mu crankcase, kumanikidzwa kwe crankcase kuchawedzera, izvo zvinokanganisa piston pasi, asiwo zvinokanganisa mashandiro e sealing einjini. Saka, zvakakosha kuburitsa magasi aya ari mu crankcase. Kana magasi aya akaburitswa zvakananga mumhepo, zvinosvibisa nharaunda, ndosaka mainjiniya vakagadzira crankcase forced ventilation system. Crankcase forced ventilation system inodzosera gasi kubva mu crankcase kuenda ku intake manifold kuitira kuti ipinde zvakare mu combustion chamber. Kunewo chikamu chakakosha che crankcase ventilation system, inonzi oil and gas separator. Chikamu chegasi chinopinda mu crankcase i exhaust gas, uye chikamu i oil vapor. Oil and gas separator ndeyekuparadzanisa exhaust gas kubva ku oil steam, izvo zvinogona kudzivirira oil inopisa injini. Kana muchina wekuparadzanisa mafuta negasi ukatyoka, uchaita kuti utsi hwemafuta hupinde mu cylinder kuti hubatanidzwe mukutsva, izvo zvichaita kuti injini itsve mafuta, uye zvichakonzerawo kuwedzera kwekuunganidzwa kwekabhoni mukamuri yekutsva. Kana injini ikapisa mafuta kwenguva yakareba, zvinogona kukonzera kukuvara kwe three-way catalytic converter.
