Ndedzipi Nzira dzekuedza dzeExhaust Catalytic Converters?

Visual Inspection:Tarisa iyo exhaust catalytic converter yekukuvara uye kuwandisa panguva yekutyaira. Mushure mekusimudza mota, tarisa iyo catalytic inoshandura nzvimbo yemazino. Mazino aripachena uye zvikwambo zvinoratidza kukuvara kunogona kuitika kune catalytic converter carrier. Tarisa uone chigadziriso chemba chemavara akaomarara kana kuti neruvara rushoma -pepe marks. Tarisa uone zvakanyanya kuoneka rima grey mavara pakati pecatalytic converter inodzivirira kavha; izvi zvinoratidza kuti catalytic converter yanyanya kupisa uye kumwe kuongorora kunodiwa.

Back Pressure Test:Dhonza buri panzvimbo yakafanira papombi yekubuditsa pamberi peexhaust catalytic converter uye batanidza geji yekumanikidza. Tanga injini uye kuyera kupera kwemashure kudzvinyirira pasina basa uye 2500 rpm. Kana iyo exhaust yekudzokera kumashure ikasapfuura iyo injini yakatarwa muganhu, iyo catalytic inoshandura inotakura haina kuvharwa.

Vacuum Test:Batanidza vacuum geji kune yakawanda yekudyara, tanga injini, uye zvishoma nezvishoma wedzera kumhanya kwayo kubva pakusaita basa kusvika 2500 rpm. Tarisa kuchinja kwevacuum gauge. Kana iyo vacuum level ikadonha panguva ino, chengetedza injini kumhanya pa2500 rpm. Kana iyo vacuum level yekuverenga ichidonha zvakanyanya mushure, zvinoratidza kuti exhaust catalytic converter yakavharwa.
