Nedambudziko rini mastalls emota kana braking zvese mutyairi wecarburetor nemota yejekiseni zvinogona kubonderana. Kuputsika kwakadaro, kunze kwekusagadzikana, kunogonawo kutungamirira kune dambudziko. Mushure mezvose, mota inogona kumira kwete chete panguva inorema braking, asiwo pakutendeuka kana pamberi pechipingamupinyi. Kazhinji kazhinji, vatyairi vemotokari vane carburetor vanotarisana nedambudziko rakadaro. Zvisinei, motokari dzemazuva ano dzejekiseni hadzina kudzivirirwa kubva kune dambudziko rakadai. Zvikonzero nei injini yekupisa yemukati inogona kumira paunenge uchidzvanya brake pedal panogona kunge paine akati wandei - kuputsika mukushanda kwevacuum brake booster, depressurization yepombi yayo, matambudziko nepombi yemafuta kana idle speed sensor (yejekiseni). Muzvinyorwa izvi tichakupa ruzivo rwakakodzera, izvo zvichakubatsira kugadzirisa kuparara iwe pachako. Asi iwe unogona kuratidza chikonzero chechokwadi chekuparara chete mushure mekuita ongororo uye zvakadzama diagnostics yemotokari.

Kazhinji, kuparara kwakadaro kunoratidza kuparara kwebhureki system, saka hatikurudzire kushandisa mota yako kusvika panguva yainogadziriswa. Izvi zvinokudzivirira kubva mukukonzera tsaona mumigwagwa.

Zvikonzero zvikuru

Kana iyo injini yekupisa yemukati yemotokari yako ichimira kana braking, saka panogona kunge paine zvikonzero zvakawanda zveizvi. Nekudaro, iwo makuru ndeaya:

• kuputsika mukushanda kwevacuum brake booster;
• depressurization yeVUT hose;
• matambudziko mukushanda kwepombi yemafuta;
• kusashanda mune isina basa yekumhanyisa sensor (yeinjini dzejekiseni);
• kushanda kusina kururama kwemotokari yemagetsi ekudzora unit (kana yakaiswa).

kunewo zvimwe zvikonzero zvinoverengeka, zvishoma, zvatichakurukurawo pazasi. Saka ngatitangei muhurongwa.

Depressurization yeVUT kana hose yayo

Iyo vacuum brake booster (yakapfupikiswa seVUT) inoshanda kudzikamisa kuedza kunogadzirwa nemutyairi nekutsikirira brake pedal. Inowanikwa pakati pe master brake cylinder ndokuti pedal. Basa rake rakabatanidzwa nehuwandu hwekutora, kwaanobatanidzwa nehose yevacuum. Tichaongorora basa rake gare gare. Iyo VUT dhizaini, kuwedzera kune zvimwe zvinhu, inosanganisirawo membrane. Kana ikakuvadzwa kana kusashanda nemazvo, ichi chingave chimwe chezvikonzero nei ichimira kana ichibhureki.

kureva, kana iwe uchidzvanya zvakanyanya brake pedal, iyo ine kukanganisa membrane haina nguva yekugadzira vacuum, ndosaka chikamu chemhepo chiri mu brake system. inopinda musanganiswa wemafuta. Ichi ndicho chikonzero nei injini inomira kana ichiita mabhureki.

Kuputsika kwakadaro kunogona kuonekwa nyore nyore iwe pachako. Iyo inotevera algorithm yezviito inofanira kuteverwa:

• kudzima injini yemoto mukati memoto (kana yakashanda kare);
• kakawanda (4 ... 5) dzvanya uye usunungure brake pedal (pakutanga pedal stroke ichava "nyoro", uye ipapo sitiroko ichava "yakaoma");
• chengetedza pedal panzvimbo yepasi netsoka yako;
• tanga injini inopisa mukati;
• kana panguva yekutanga injini yekupisa mukati iyo pedal "yakundikana", saka zvinhu zvose zvakarongeka ne "vacuum tank" uye iyo yose system, kana ikaramba iripo, unofanira kutarisa matambudziko.

Kuongorora basa reVUT

zvakare imwe nzira:

• mushure mekunge injini yekupisa yemukati yashanda kwenguva yakati, dzvanya brake pedal;
• kukanganisa injini inopisa mukati;
• chengeta pedal yakaora mwoyo kweinenge 30 seconds;
• kana panguva ino pedal isingaedzi kusimuka uye isingarambi gumbo, saka zvinhu zvose zvakarongeka neVUT nehurongwa hwose.

kazhinji, vacuum booster haina kugadziriswa, asi kuchinja zvachose, muzviitiko zvisingawanzogadziriswa zvinogoneka, asi havasi vese vatenzi vanozviita. Uye kwete chero motokari yakadaro kugadzirisa kunobatsira. Naizvozvo, kana paine kukundikana kweVUT, isu tichiri kukurudzira kuti uitsive.

zvakare chimwe chikonzero nei mota ichimira kana braking ingave hose depressurization, iyo inobatanidza vacuum brake booster uye manifold ekutora. Iyo yekupedzisira inovimbisa kuumbwa kwakarurama kwemhepo-mafuta musanganiswa, iyo inodyiswa mberi mukati mejini inopisa mukati.
