Injini yekudzima moto kutadza kunoitika kana brake pedal ichidzvanywa.

Phenomenon: Kana brake pedal yakaora mwoyo, braking effect haina kunaka, uye panguva imwe chete, injini inodedera zvine simba kwenguva shoma shoma yobva yadzima, uye motokari inotadza kuzvidzora uye inoramba ichitsvedza mberi.

Analysis:

1. Kana mabhureki emoto akabuda pamotokari dzinofambiswa nemaoko, funga kana chiri chinhu chakajairika chekubhureki moto une magiya.

2. Mabhureki akaenzana nekusunungura chinofambisa chinyadzo neimwe nzira, tichifunga kuti mota isina basa inonamira panzvimbo yakaderera.

3. Kana iyo vacuum booster yakabhurwa, pane vacuum air leakage.

4. Nemhaka yokuti motokari iri otomatiki, moto webhureki une gear haufungidzirwe.

5, ona kuti hapana chikanganiso kodhi

6. Mushure mekuferefeta, kumhanya kusingashande kweinjini kwakagadzikana panenge 850 rpm, iyo inosangana nezvinodiwa zvakajairika. Zvinoratidza kuti iyo isina-isimbe mota yakanamatira munzvimbo yakaderera.

7. Paunotsika bhureki uchimhanya usingaite, injini inodzima mushure mekudedera zvine simba kwenguva shoma, uye panguva imwe chete, pedal inonzwa yakaoma, izvo zvinogona kungokonzerwa nekubuda kwevacuum. Nekudaro, nekuda kwekushanda kwakajairwa kweinjini nekumhanya kusingaite uye kutyaira kwakajairwa, pombi yevacuum inobatanidza vacuum booster neyakawanda yekutora haina kutariswa, uye kukanganisa kwakavharwa pane vacuum booster.

8. Batanidza vacuum gauge kune yakawanda yekutora kuti uedze. Pakumhanya kusingaite, iyo vacuum degree ndeye 64Kpa. Panguva inotsikirirwa brake pedal (injini inotanga kuzununguka, asi haina kudzima), vacuum degree inodonha kusvika 15Kpa. Nekuda kweiyo shanduko huru, iyo booster chete inogona kuve nemhepo yakakura kudaro yekudonha muhurongwa hwekudya (iyo vacuum chubhu yakakora kwazvo). Kugadzirisa matambudziko mushure mekutsiva.

Kuongororwa:

Kuruboshwe nekurudyi mhepo makamuri ari vacuum booster haigoni kunyatsovharwa panguva braking, izvo zvinotungamirira kuwanda mhepo kupinda kuruboshwe mhepo chamber uye ipapo kupinda combustion chamber kuburikidza neimwe-nzira vharafu uye vacuum pombi. Nekuda kwekuti mota inoshandisa mhepo inoyerera, haikwanise kunzwa kupinza kwemhepo kuseri kwevharuvhu, izvo zvinoita kuti musanganiswa uve wakatetepa uye uchidzima moto.
