Pane suction chubhu padyo nemhepo sefa.Chii chiri kuitika?
Iyi ichubhu iri mu crankcase ventilation system inotungamirazve gasi rekuburitsa kune yakawandisa yekupisa.Injini yemotokari ine crankcase inomanikidzwa kufefetera system, uye kana injini ichimhanya, rimwe gasi rinopinda mu crankcase kuburikidza nepiston mhete.Kana gasi rakawandisa richipinda mu crankcase, kudzvanywa kwe crankcase kunowedzera, izvo zvinokanganisa piston pasi, asi zvakare zvinokanganisa kuita yekuisa chisimbiso kweinjini.Naizvozvo, zvinodikanwa kupedza magasi aya mu crankcase.Kana magasi aya akaburitswa akananga mumhepo, anosvibisa nharaunda, ndosaka mainjiniya akagadzira crankcase yekumanikidza kufefetedza system.Iyo crankcase yakamanikidzwa kufefetera system inodzoreredza gasi kubva ku crankcase kupinda mune yekudyara manifold kuitira kuti ipinde mukamuri yekupisa zvakare.Kune zvakare chikamu chakakosha che crankcase ventilation system, iyo inonzi mafuta uye gasi separator.Chikamu chegasi rinopinda mucrankcase gasi rekupedza, uye chikamu imhute yemafuta.Oiri uye gasi separator ndeyekuparadzanisa gasi rekubuda kubva muutsi hwemafuta, izvo zvinogona kudzivirira injini kupisa chiitiko chemafuta.Kana iyo mafuta uye gasi separator yakaputsika, ichaita kuti mafuta emafuta apinde muhumburumbira kuti atore chikamu mukupisa, izvo zvichaita kuti injini ipise mafuta, uye ichaitawo kuti kuwedzera kwekabhoni kuunganidzwa mukamuri yekupisa.Kana injini ikapisa mafuta kwenguva yakareba, inogona kukonzera kukuvadza kune matatu-nzira inoshandura inoshandura.
