"Injini inopisa mafuta" inoreva kuti mafuta ejini anopinda mukamuri inopisa yejini uye anotora chikamu mukupisa pamwe chete nemusanganiswa, zvichiita kuti injini irasike kurasikirwa uye kubuda kwemafuta. Zvinetso zvinowanzoitika zvinowanzokonzera injini "kupisa mafuta" zvisimbiso zvemafuta evharuvhu uye zvindori zvepiston. Saka ko kana tikatonga kana iri dambudziko remhete yepiston kana dambudziko remafuta evhavha? Ngatitarisei pamwe chete. Chokutanga pane zvose, ngatitangei kunzwisisa chikonzero chekupisa mafuta

· Valve chisimbiso

Chisimbiso chemafuta evhavha hachina kudzvinyirirwa;

Kusununguka kukuru pakati pegwara revhavha uye cylinder musoro;

Kupfeka kwevhavha yemafuta chisimbiso, kupfeka kwakanyanya kwevhavha stem uye gwara revhavha;

Kuchembera kwechisimbiso chemafuta evharuvhu kunoita kuti mafuta ayerere achitevedza dzinde revharuvhu kuenda kukamuri rinopisa, zvichiita kuti mafuta apise. ·Piston mhete

Mhete yepiston inoiswa kumusoro pasi;

Iyo piston mhete haina kudzika sezvinodiwa;

Iyo yekunze dhayamita yepiston mhete idiki zvakanyanya uye kubvumidzwa pakati pe cylinder dhayamita yakakura;

Mukugadzirisa uye kushandiswa, zvisina hanya chenesa piston mhete, piston uye cylinder kupfeka;

Iyo piston mhete ine kushomeka kwekusagadzikana uye kupera nguva isati yakwana, zvichiita kuti mafuta apinde mukamuri yekupisa uye kupisa mafuta;

Pistons uye cylinder barrels zvinopfekwa. Mukana uri pakati pepiston dhayamita uye cylinder barrel inodarika kukosha kwakatarwa. · Zvimwe zvikonzero

Mhete yekoroti haina kuiswa panzvimbo, zvichiita kuti groove zviratidzo pa cylinder yejini;

Kukwenya madziro ehumburumbira netsaona panguva yegungano;

Injini yakakwirira tembiricha; (usatarise kushaya mafuta, kushaya mvura kana kushaya mvura)

Iyo yekuzora mhedzisiro yemafuta einjini haina kunaka;

Haidziye mota, inokonzera kupera uye kubvaruka;

Pombi yepeturu inopinda mukamuri rinopisa.
Ndedzipi nzira dzekutonga kupisa kweinjini mafuta?

Kune marudzi matatu ekupisa mafuta emota (zvichitevedzana, kupisa injini yemafuta mumotokari inotonhora, kupisa injini mafuta kana uchimhanyisa uye kupisa injini yemafuta chero nguva)

·Kutonga nzira yevharuvhu mafuta seal kupisa mafuta

1) Nzira dzekuwedzera uye kusunungura iyo throttle;

2) Yakakomba kabhoni deposits uye blockage yenzira nhatu-catalyst;

3) Kana iyo inopopota ichipfungaira utsi hwebhuruu, zvinoreva kuti mota yatopisa injini mafuta. Kana utsi hwebhuruu hukanyangarika mushure mekunge motokari yapisa, rudzi urwu rwemafuta ejini inotonhorera injini yemafuta. (Izvi imhaka yekuti chisimbiso chemafuta evhavha chiri kuchembera kana kukuvadzwa, zvichikonzera kusaisa chisimbiso, uye mafuta anopinda muhumburumbira kubva muvharuvhu).

·Kutonga Nzira yePiston Ring Kupisa Mafuta

1.Pashure pemotokari inopisa, kana iri kukurumidza kukurumidza kana kuti idling process, chero bedzi iyo kukurumidza ichikwira nokukurumidza, utsi hwebhuruu huchabudiswa kubva pombi yekupedza. Rudzi urwu rwekukurumidza kukurumidza kupisa mafuta. (Kukurumidzira kukurumidza kwekupisa kwemafuta kunonyanya kukonzerwa nekushaya chisimbiso kwechisimbiso pakati pemadziro emukati cylinder uye piston mhete, izvo zvinoita kuti mafuta apinde mukamuri yekupisa zvakananga kubva kune crankcase);

2.Paunenge uchiyera cylinder pressure, kana pane dambudziko nemhete yepiston, chiyero chekupfeka chinogona kutongwa nedhesi yedhivhavha (kana isiri yakanyanya kuoma, kana kuti cylinder dambudziko, nekuwedzera mugadziri wekugadzirisa, inofanirwa. ichagadziriswa otomatiki mushure memakiromita 1500). ·Nzira dzekutonga kune zvimwe zvikonzero

Kana yangotanga, utsi hwebhuruu hunogona kuonekwa. Panguva ino, injini yemafuta yatove yakakomba, uye panogona kunge paine njodzi yekuchengetedza. Mafuta emhando iyi anopiswa chero nguva. (Injini yakasakara zvakanyanya, zvichikonzera kuvharika kwekuvhara, izvo zvinopa mamiriro akanaka ekupisa mafuta. Panguva ino, inofanirwa kugadziriswa nekuchimbidza kudzivirira kutadza kwakanyanya uye kukuvara)
