Imaphi amagesi i-OBD ewatholayo ku-exhaust?

Injini yakho isebenza lapho kusha—umlilo—okudala amagesi akhipha umoya. Izinhlobo eziningi zamagesi zikhiqizwa ngesikhathi sokusebenza okuvamile futhi kufanele zilawulwe njengoba eziningi ziba ukungcola lapho zikhishwa emkhathini. Empeleni kuwumbono oyiphutha ovamile wokuthi uhlelo lwemoto yakho lokuxilonga (OBD) luthola amagesi, kodwa akunjalo. Ithola amaphutha emishinini yokukhipha umoya (i-catalytic converter, izinzwa ze-oxygen, i-valve yokuhlanza ithangi likaphethiloli, njll.).

izinzwa ze-oxygen

Ingxenye yokudideka lapha ihlobene nesiguquli se-catalytic kanye nezinzwa zomoya-mpilo wemoto. Imoto yakho ingaba nesiguquli se-catalytic esisodwa noma ezimbili kanye nezinzwa zokwenza umoya-mpilo eyodwa noma ngaphezulu (ezinye zinezinzwa zomoya-mpilo eziningi ezitholakala ezindaweni ezihlukene kusistimu yokukhipha umoya).

Isiguquli se-catalytic sitholakala cishe maphakathi nepayipi le-exhaust ezimotweni eziningi (yize lokhu kungase kuhluke). Umsebenzi wawo ukushisa nokushisa amagesi e-exhaust akhona kuzo zonke izimoto. Nokho, uhlelo lwe-OBD aluwalinganisi la magesi, ngaphandle komoyampilo.

Izinzwa zomoya-mpilo (noma izinzwa ze-O2) zinesibopho sokulinganisa inani le-oxygen engashisiwe emshinini wokukhipha umoya wemoto yakho bese zidlulisela lolo lwazi kukhompuyutha yemoto. Ngokusekelwe olwazini oluvela kuzinzwa ze-O2, ikhompuyutha ingakwazi ukulungisa ingxube yesibaseli somoya ukuze ingasebenzi izancile noma inothe (i-oxygen encane kakhulu noma i-oxygen eningi, ngokulandelanayo).

Ezinye izingxenye ezilawulwa uhlelo lwe-OBD

Uhlelo lwe-OBD luqapha inani lezingxenye ezihlukene ezihlobene nesistimu kaphethiloli/yokuhwamuka, isistimu yokukhipha umoya, nezinye izinhlelo, okuhlanganisa:

  • I-valve ye-EGR
  • I-Thermostat
  • I-heater ye-catalytic
  • Isistimu yokungenisa umoya ye-crankcase ephoqelelwe
  • Ezinye izingxenye zesistimu ye-AC

Kodwa-ke, uhlelo lwe-OBD aluqapheli amagesi - luqapha amandla kagesi nokumelana, okungabonisa inkinga ngalezi zingxenye (ngakho-ke ukukhishwa okuphelele kwemoto ngokwayo).
