I-database isetshenziswa kanjani lapho kudlula Ukuhlolwa Kombuso Kwezobuchwepheshe?
Uma uhlala endaweni edinga ukuhlolwa kokukhishwa kwekhabhoni minyaka yonke, uzodinga ukwenza ukuhlolwa okuyizingxenye ezimbili. Isikhungo sokuhlola sizokwenza izinto ezimbili: ukukala amagesi ku-exhaust nge-exhaust pipe test, futhi...
Uma uhlala endaweni edinga ukuhlolwa kokukhishwa kwekhabhoni minyaka yonke, uzodinga ukwenza ukuhlolwa okuyizingxenye ezimbili. Isikhungo sokuhlola sizokwenza izinto ezimbili: ukukala inani lamagesi ku-exhaust ngokuhlolwa kwepayipi le-exhaust futhi uhlole uhlelo lwakho lwe-OBD (on-board diagnostics). Iyiphi indima edlalwa uhlelo lwe-OBD lapha? Kungani udinga isheke lesistimu ye-OBD uma isikhungo senza isheke lepayipi lokukhipha umoya?
Izizathu Ezimbili Zokuhlolwa Kwezinyathelo Ezimbili
Empeleni kunesizathu esilula kakhulu sokuthi kungani isikhungo sokuhlola endaweni yangakini singadinga isheke le-OBD ngaphezu kokuhlola ipayipi lokukhipha umoya. Ngokuphambene nenkolelo evamile, uhlelo lwe-OBD alulinganisi amagesi ngaphandle komoyampilo. Ukuhlolwa kwepayipi le-exhaust kuyadingeka ukuze uhlaziye amagesi ahlukahlukene akhiqizwa futhi uqiniseke ukuthi imoto yakho ingaphakathi kwemingcele ebekwe uhulumeni.
Isizathu sesibili sihlobene nesokuqala. Ukuhlolwa kwepayipi le-exhaust kuhlola kuphela ukuba khona kwamagesi ekukhishweni kwakho. Ayikwazi ukuhlola isimo sezingxenye zakho zokulawula ukungcola. Yilokho okwenziwa isistimu ye-OBD - iqapha okokusebenza kwakho kokukhipha umoya njenge-catalytic converter, inzwa yomoya-mpilo, kanye nevalvu ye-EGR. Uma kunenkinga ngeyodwa yalezi zingxenye, ikhompuyutha yemoto ibeka ikhodi yesikhathi. Uma inkinga itholwa izikhathi ezingaphezu kwesisodwa, ikhompuyutha ivula ukukhanya kwe-Check Engine.
Yenzani uhlelo lwe-OBD
Uhlelo lwe-OBD lwenza okungaphezu nje kokukhanyisa lapho ingxenye yehluleka. Iyakwazi ukubona ukuguga okuqhubekayo kwezingxenye zesistimu yokulawula ukungcola kwemoto yakho. Lokhu kusiza ukugwema ukulimala okungase kube yingozi emotweni futhi kuqinisekisa ukuthi ungakwazi esikhundleni semishini yokulawula ukungcola ehlulekile ngaphambi kokuba imoto iqale ukungcolisa kakhulu imvelo.
Uma ilambu le-Check Engine likhanya kudeshibhodi, imoto yakho izofeyila uhlolo lokukhishwa kwekhabhoni njengoba kunenkinga edinga ukulungiswa kuqala. Nokho, imoto yakho ingase ingaphumeleli esivivinyweni ngisho noma ilambu elithi "Hlola Injini" livaliwe, ikakhulukazi uma uhlulekile ukuhlolwa kokucindezela kwegesi.
