Kutsiva kana kusatsiva?

Kune kukakavara kusingaperi pakati pevatyairi pamusoro pekuti zvakakosha here nguva nenguva - kuverenga: kamwe chete pagore kushandura mafuta ejini mumotokari. Kunyange zvazvo vatyairi vakawanda vachibvuma kuti izvi zvinofanira kuitwa pashure pokushandisa motokari zvikuru uye pashure penguva refu, havabvumirani zvikuru pamusoro pemotokari dzisingawanzotyairwa. Zvichakadaro, muoiri yeinjini, zvisinei nekuti mota inoitwa sei, maitiro asina kunaka anoitika anogona kupfupisa hupenyu hweinjini. Pazasi isu tinonyora mamwe akanyanya kukosha ayo, ayo achabvisa kusava nechokwadi chero pamusoro pemazano ekugara achichinja mafuta einjini.

Okisijeni, iyo inokuvadza

Munguva yekushanda kwezuva nezuva kwemotokari, maitiro anokuvadza e oxidation yeinjini oiri anoitika. Mhosva huru ndeyeokisijeni, kupindirana kunoshandura chikamu chezvikamu zvemafuta kuita peroxides. Izvi, zvakare, zvinoora kuita madoro uye asidhi uye, nekudaro, zvinononoka zvinhu zvinokuvadza injini. Kana tikawedzera kune iyi soot yakaumbwa panguva yekupisa kwemafuta, uye yakapfekwa zvimedu zvezvikamu zvesimba remagetsi, tinowana musanganiswa une mhedzisiro yakaipa kwazvo pamafuta einjini. Iyo yekupedzisira inorasikirwa neiyo viscosity yakakodzera uye kugona kugamuchira kupisa. Kushaikwa kwekuzora kwakakodzera kunotungamirirawo kune kushaya simba kana kunyange kubvongodzwa kwefirimu yemafuta kubva kumasilinda, iyo yakaipisisa inogona kutungamirira kukutora injini.

Sediment inosvibisa

Oxygen haisi iyo chete "chepfu" mumafuta emotokari. Mhando dzakasiyana-siyana dzezvinosvibisa zvinouya kwairi kubva mumhepo zvinewo mhedzisiro yakaipa. Mukubatana nepamusoro-soro resinous zvinhu, ivo vanogadzira sludge, iyo kuunganidza iyo inoita kuti zviome uye dzimwe nguva zvisingakwanisi kushanda iyo lubrication system, semuenzaniso, nekuda kwekuvhara mafirita. Nekuda kweizvozvo, vanomira kuita mabasa avo uye mafuta anoyerera achibuda kuburikidza neyakavhurwa vharafu yekudzivirira. Hunhu hwemafuta einjini zvakare hunodzikira pasi pesimba remafuta. Paunenge uchityaira painjini inotonhora, mafuta haabvisike nekukurumidza zvakakwana (kunyanya mumotokari dzine chikanganiso chekubatidza system) uye inonatsa mafuta, ichiyerera ichidzika nemadziro ecylinder kupinda musump.

Vanonatsa vanosakara

Havasi vese vatyairi vanoziva kuti kune anenge asina anovandudza anoshandiswa uye asina kuchinjwa mafuta einjini kwenguva yakareba, iro basa nderekuvandudza zvidziviriro zveiyo mafuta layer - iyo inonzi firimu pane yakaomeswa nzvimbo. Nekuda kweizvozvo, iyo yekupedzisira inopera nekukurumidza, izvo zvinozoita kuti injini ikundikane. Sezvinoita zvekunatsa, izvi zvinoshandawo kune rimwe basa iro mafuta emota anofanira kuita. Ndezvei? Nekuda kwekusarerekera kweanokuvadza acids, kunyanya sarufa zvinobva kune ese mafuta: peturu, dhiziri uye LPG. Kushanda nemazvo oiri yeinjini, ine alkaline reaction, inogadzirisa zvinokuvadza zveasidhi mujini. Izvi zvakakosha kudzivirira kuparara kwe powertrain zvikamu, kunyanya bushings uye pistons. Oiri inoshandiswa zvakanyanya inorasikirwa nehunhu hwayo, uye injini haichadzivirirwe kubva kune zvine hukasha.

Mafuta anofanira kuchinjwa

Njodzi dzekutyaira neyakashandiswa uye isina kuchinjika injini yemafuta yataurwa pamusoro inofanira kukupa iwe chikafu chekufunga. Naizvozvo, nguva nenguva kutsiva kwakasimbiswa neautomaker haisi ngano kana whims. Kuunganidzwa kwezvinhu zvinokuvadza muoiri yeinjini, zvakasanganiswa nesimbi zvimedu zvezvipfeko zveinjini, zvinogadzira chinhu chine njodzi zvakanyanya chinokwenya chinopinda mumanooks uye crannies yemagetsi unit. Kuita kuti zvinhu zvinyanye kuoma, mafirita emafuta akavharwawo, zvichiita kuti mafuta acho aunzwe pakanyanya kuderera. Iyo yekupedzisira, zvakare, inogona kutungamirira mukukuvadzwa kusingachinjiki kune zvakatenderedza zvinhu zveinjini, senge hydraulic lifters, bushings, uye mumotokari dzine turbocharger, mabhengi avo.

Saka, nguva nenguva shandura mafuta mujini, kunyange neine yakaderera mileage, kana kwete? Mushure mokuverenga rugwaro urwu, zvichida hapana achave nekusava nechokwadi pamusoro pekuratidza mhinduro yakarurama.
