3 zvikonzero zvikuru zveinjini mafuta kuti apinde mumhepo sefa
Zviri mukati
Iyo mhepo sefa yakagadzirirwa kuteya marara, tsvina uye zvimwe zvinosvibisa, kwete mafuta. Dzimwe nguva, apo mechanic yebasa remunharaunda inotsiva sefa yemhepo, nyanzvi icharatidza kuti mafuta einjini awanikwa; ingave mukati memhepo sefa imba kana yakavakwa musefa yakashandiswa. Nepo oiri iri mumhepo sefa isingawanzo chiratidzo chekutadza kweinjini ine njodzi, haifanirwe kufuratirwa. Ngatitarisei zvikonzero zvitatu nei mafuta achipinda musefa yemhepo.
1. Yakavharwa yakanaka crankcase ventilation (PCV) valve.
Iyo PCV valve yakabatana nemhepo inotora imba, kazhinji nerubber vacuum hose, iyo inoshandiswa kubvisa vacuum mukati meinjini crankcase. Ichi chikamu chinowanzoiswa pamusoro pevhavhavhavha yevhavha yevhavha, uko kumanikidzwa kunoyerera kubva pasi pehafu yeinjini kuburikidza nemisoro yehumburumbira uye kunze kwechiteshi chekupinza. Iyo PCV valve yakafanana nejini yemafuta sefa mune iyo nekufamba kwenguva inovharika nemarara akawandisa (injini yemafuta mune iyi kesi) uye inofanirwa kutsiviwa zvichienderana nekurudziro yemugadziri wemotokari yako. Kana vheji yePCV isingatsiviwa sezvakakurudzirwa, mafuta akawandisa achapukunyuka kuburikidza nePCV valve uye apinde mumhepo yekutora mhepo.
Mhinduro yei? Kana vheji yePCV yakavharwa inowanikwa kuti ndiyo inokonzera mafuta ejini mukati memhepo yako yemhepo kana mhepo yekutora mhepo, inofanira kuchinjwa, kunwa kwemhepo kunocheneswa, uye itsva air filter yakaiswa.
2. Zvindori zvepiston zvakapfekwa.
Yechipiri inogona kubuda yeoiri yeinjini inopinda mumhepo sefa imba inopfekwa piston mhete. Zvindori zvepiston zvakaiswa pamucheto wekunze wepiston mukati mekamuri rinopisa. Mhete dzakagadzirirwa kugadzira kupisa kwemoto uye kubvumira mashoma emafuta einjini kuti arambe achizora mukati mekamuri yekupisa panguva yega yega piston sitiroko. Kana mhete dzapera, dzinoregedzera uye dzinogona kukonzera kuputika kwemafuta, izvo zvinowanzoratidza seutsi hwebhuruu hunobuda mupombi yepombi yemotokari uchityaira. Mumatanho ekutanga episton mhete yekupfeka, yakawandisa mafuta seepage inogona kukonzera yakawandisa kudzvanywa mukati me crankcase, iyo inotungamira mamwe mafuta kuburikidza nePCV vharafu uye pakupedzisira ichipinda mumhepo yekupinda sezvataurwa pamusoro.
Mhinduro yei? Kana iwe ukaona oiri yeinjini mumhepo yako sefa kana mhepo inotora imba, nyanzvi mechanic inogona kukurudzira kuti utarise kudzvanywa. Pano makanika anoisa yekumisikidza geji pane yega yega spark plug gomba kuti atarise kudzvanywa mucylinder yega yega. Kana iyo compression yakaderera pane yainofanira kunge iri, chikonzero chinowanzopfekwa piston zvindori. Zvinosuruvarisa, kugadzirisa uku hakusi nyore sekutsiva PCV valve. Kana zvindori zvepiston zvakapfekwa zvikaonekwa kuti ndiko kwabva, chingave chinhu chakanaka kutanga kutsvaga imwe mota yekutsiva, sezvo kutsiva mapiston nemarin'i zvingangodhura kupfuura kukosha kwemotokari.
3. Migero yemafuta yakavharwa
Chekupedzisira chinogoneka chikonzero chekuti oiri yeinjini ipinde mumhepo inotora system uye pakupedzisira kuvhara iyo sefa yemhepo imhaka yekuvharika kwemafuta ndima. Chiratidzo ichi chinowanzoitika kana injini yemafuta uye sefa zvisina kuchinjwa sezvakakurudzirwa. Izvi zvinokonzerwa nekuwanda kwekuwanda kwekabhoni deposits kana sludge mukati meinjini crankcase. Kana mafuta achiyerera zvisina kunaka, kuwedzera kwemafuta kunowedzera mujini, zvichiita kuti mafuta akawandisa asundirwe kuburikidza nePCV valve kupinda mumhepo.
Mhinduro yei? Muchiitiko ichi, zvakakwana kuti dzimwe nguva uchinje injini yemafuta, sefa, PCV valve uye kutsiva tsvina yemhepo. Zvisineyi, kana pakavharwa mapassword emafuta akawanikwa, zvinogaro kurudzirwa kugezesa oiri yeinjini uye kushandura sefa yeoiri kanenge kaviri mukati memakiromita ekutanga e1,000 kuti ive nechokwadi chekuti nzira dzemafuta einjini dzakachena nemarara.
Ibasa rei sefa yemhepo?
Iyo sefa yemhepo pane mazhinji emazuva ano emukati emoto injini inowanikwa mukati memhepo inotora imba, iyo yakaiswa pamusoro peinjini. Inosungirirwa kune jekiseni yemafuta (kana turbocharger) uye yakagadzirirwa kunyatsopa mweya (oxygen) kumafuta emafuta kuti asanganise nemafuta asati apinda mukamuri rinopisa. Basa guru resefa yemhepo nderekubvisa zvimedu zvetsvina, guruva, marara uye kumwe kusvibiswa mhepo isati yasangana nepeturu yemvura (kana mafuta edhiziri) yoshanduka kuita chiutsi. Kana iyo mhepo sefa yakavharwa nemarara, zvinogona kukonzera kudzikiswa kwemafuta uye kubuda kwemagetsi enjini. Kana mafuta akawanikwa mukati mesefa yemhepo, izvi zvinogona zvakare kukanganisa zvakanyanya kushanda kweinjini.
Kana uri kuita zvechinyakare kugadzirisa pamota yako, rori, kana SUV uye ukawana mafuta einjini mukati mesefa yemhepo kana imba yekupinza mhepo, ringava zano rakanaka kuita kuti makanika ane hunyanzvi auye kwauri kuzoongororwa panzvimbo. Kuziva nzvimbo yekutanga nemazvo kunogona kukuchengetedza mari yakawanda pakugadzirisa kukuru kana kutsiva mota yako nguva isati yasvika.
