Ndeapi magasi anoonekwa neOBD mukupopota?
Injini yako inomhanya nekupisa-moto-izvo zvinogadzira gasi rekupedza simba. Magasi akasiyana-siyana anogadzirwa panguva yekushanda kwakajairika uye anofanirwa kudzorwa sezvo mazhinji achizosvibisa kana aburitswa mumhepo. Iri chaizvo pfungwa isiriyo yekuti mota yako iri pa-board diagnostic (OBD) system inoona magasi, asi handizvo. Inoona zvikanganiso mumidziyo yekupedza simba (catalytic converter, oxygen sensors, fuel tank purge valve, etc.).
Oxygen sensors
Chikamu chenyonganiso pano chine chekuita necatalytic converter uye mota yeokisijeni sensor(s). Mota yako inogona kunge iine imwe kana maviri anoshandura anoshandura uye imwe kana anopfuura maokisijeni sensors (mamwe ane akawanda maokisijeni sensors ari munzvimbo dzakasiyana mu exhaust system).
Iyo catalytic inoshandura inowanikwa pakati pepombi yekupedza simba pamotokari zhinji (kunyangwe izvi zvingasiyana). Basa rayo nderekupisa nekupisa magasi emhepo aripo mumotokari dzese. Nekudaro, iyo OBD system haiyere magasi aya, kunze kweokisijeni.
Masensa eOxygen (kana maO2 sensors) ane basa rekuyera huwandu hweokisijeni isati yapiswa mumotikari yemota yako uyezve kuendesa ruzivo irworwo kukombuta yemota. Kubva pane ruzivo kubva kuO2 sensors, kombiyuta inogona kugadzirisa musanganiswa wemhepo-mafuta kuitira kuti irege kumhanya yakaonda kana kupfuma (yakanyanya oksijeni kana yakawandisa okisijeni, maererano).
Zvimwe zvikamu zvinodzorwa neOBD system
Iyo OBD system inotarisisa akati wandei akasiyana zvinhu zvine chekuita nemafuta / evaporation system, emission system, uye mamwe masisitimu, anosanganisira:
- EGR vharafu
- Thermostat
- catalytic heater
- Yakamanikidzwa crankcase ventilation system
- Zvimwe zvikamu zve AC system
Nekudaro, iyo OBD system haitarise magasi - inotarisisa voltage uye kuramba, izvo zvinogona kuratidza dambudziko nezvikamu izvi (uye nekudaro kuburitsa kwese kwemotokari pachayo).
