Ndeapi matambudziko ekutarisira kana injini yemafuta ikapinda mumhepo sefa, uye zvekuita
Wese ane ruzivo muridzi wemota akaona mafuta-yakasvibiswa mweya sefa kamwechete mubiography yake. Zvechokwadi, ichi chiratidzo chekushaya simba, asi zvakakomba sei? Portal "AvtoVzglyad" yakafunga nyaya yakasviba yakadaro.
Mamiriro ezvinhu apo, panguva yegadziriro yakarongwa, tenzi anoburitsa sefa yemhepo uye anoratidza muridzi mavara akasiyana emafuta einjini akafanana nebhaisikopo rinotyisa. Kuwana mafuta uye mafuta mu "air intake" chiratidzo-saka. Mushure mezvose, ichi chiratidzo chakakora pakusashanda kweiyo inodhura uye yakaoma kugadzirisa unit yemota chero ipi zvayo - injini. Tichifunga nezvechishuwo chakapararira chekuita kutsiva kwakazara kweyuniti, pachinzvimbo chekubvisa uye kutsvaga chikonzero, zvibodzwa zvichave zvitanhatu. Asi dhiyabhorosi anotyisa sezvaanopendwa here?
Chikonzero chekutanga uye chakakosha cheoiri kupinda mu "mhepo" yakavharwa machani mumusoro wecylinder. Pano, maawa akawanda ekufambisa kwemotokari, uye kusachengeta nguva yebasa, uye mafuta "pamutengo" pakarepo anouya mupfungwa. Pasina kupokana, maitiro akadaro achakurumidza kutumira injini yemazuva ano yakaoma kudhishi, uye kazhinji inobatsira zvakanyanya kune mutengesi kuti atendese mutengi wake kuti iyo unit haina kukodzera kugadziriswa. Asi hazvina kukodzera kubvumirana kune imwe chikwereti pakarepo, nokuti iwe unogona kuedza decoke injini - kune nzira dzakawanda uye makemikari emotokari. Uyezve: nzira dzemafuta e "shati" dziri kure nechikonzero chega chemafuta einjini kupinda mumhepo sefa imba.
Iri "dambudziko" rinogonawo kuitika nekuda kwekuwedzera kwekupfeka kwezvindori pamapistoni, ayo anokonzera kumanikidzika mukati memasilinda uye kukora kwefirimu yemafuta pamadziro. Kana iyo inopera ikaita grey, senge nzanga yemanheru pane "girazi" redunhu, saka hazvingave zvakaipa kuyera kudzvanywa mumasilinda usati waiisa kuti igadziriswe - zvinogona kunge dambudziko rakarara mumarin'i. Ivo vanopera simba, kudzvanywa mu crankcase kunowedzera, uye crankcase ventilation valve inotanga kurasa zvakawandisa. Unofunga kupi? Ndizvozvo, mumhepo inotora system. Izvo zvakananga kune sefa yemhepo.
Nenzira, nezve PCV valve, aka crankcase ventilation. Izvo, zvisinganzwisisike, zvakare inocheneswa nguva nenguva uye kunyange kuchinjwa. Kuwanda kweakaderera-mhando, kazhinji ekunyepedzera mafuta emotokari, ayo zvino akakurira musika wepamba, kunyangwe kuedza kwese kwemakambani emafuta, pamwe nemamiriro ekushanda akaoma - guta rine jam raro harisi nyore kushivirira chero injini kupfuura. iyo yakaoma kupfuura-nzira - ita "tsvina" yavo.
Uye "chiratidzo chekutanga", chinoratidza kudiwa kwekuita "kucheneswa kukuru" mujini, kunenge kuri kuvharika kweiyo yakamanikidzwa crankcase ventilation valve. Chitarisiko chayo chichakuudza kurongeka kwezvimwe zviito, asi maitiro anoratidza kuti makore maviri kana matatu mu "sango rematombo" nokuda kwenode iyi ndiyo muganhu wakakwana.
Zvinonzwisa urombo kuti kushanda uku hakusi mumabhuku ekushanda, pamwe chete nemutengesi "mipumburu", nokuti kutarisa kushanda, pamwe nekuchenesa kana kutsiva PCV sensor, zvakanyanya kuwedzera hupenyu hwejini. Kunyanya kuoma kwemazuva ano, kuremerwa neturbine. Mushure mezvose, iyo inokanganisa sensor inogona kukonzera yakanyanya kuwedzera kudzvanywa mukati me crankcase uye kunotevera ejection yemafuta yakananga mumhepo sefa.
Mafuta ari mumhepo sefa chiratidzo chisina mubvunzo chekushanda kwakashata kweinjini, asi hazvibviri kutora mhedziso uye kuita sarudzo yeramangwana remotokari chete pane zvaunoona. Zvakakosha kuziva kuti injini inoda kutarisirwa, uye muchina wacho wose unoda mari. Uyezve, huwandu hwemari yakasimwa kazhinji hunoenderana nekutendeseka kwatenzi uye ruzivo rwemuridzi.
